About This Guide

New Features for this Release

This version of the Hotwire DSL Routers User’s Guide documents firmware

release 4.4, which adds the following new features for the Hotwire 6351

ReachDSL Router:

„

IP passthrough. This feature allows the router to pass through or share its

public IP address with a single LAN device. The DSL router establishes a

PPPoE and PPP session with the Network Access Server (NAS). The public

IP address is negotiated via IPCP, installed on the router’s DSL interface, and

served to the passthrough device via DHCP.

„

Automatic configuration of options provided by the DHCP server to its clients.

This feature is available when PPPoE is enabled and is the default unless

explicitly refused by the user. This allows the DHCP Server option

configuration items to be set automatically with values negotiated during the

network layer protocol phase of PPP (IPCP).

„

Secondary DNS server. The DHCP server can specify a secondary DNS

server in its offer to a client.

No router option required. Configuration of the DHCP Server feature no longer

requires that a value for the Router option be specified.

Introduction to Hotwire

DSL Routers

What is a Hotwire DSL Router?

The Hotwire^®DSL (Digital Subscriber Line) Router operates as a bridge and IP

router connecting a DSL link to an Ethernet network. This system provides

high-speed access to the Internet or a corporate network over a traditional

twisted-pair copper telephone line to the end user.

DSL Technologies Supported

Paradyne’s Hotwire DSL network supports the following types of technologies:

„

Hotwire IDSL (ISDN DSL) products provide IDSL multirate symmetric packet

transport and can operate over a connection with an ISDN repeater or digital

facilities. Data rates of 64 Kbps, 128 Kbps, or 144 Kbps can be configured.

„

Hotwire SDSL (Symmetric DSL) packet-based products provide high-speed

symmetric DSL services with bandwidth for business applications. These

products are configurable from 144 Kbps up to 2.3 Mbps. This gives service

providers the opportunity to sell multiple services with a single product.

„

Hotwire ReachDSL™ packet-based products provide high-speed Internet or

corporate LAN access over traditional twisted-pair copper telephone wiring,

regardless of line conditions (poor quality loops, long loops, or bad wiring at

customer premises), for guaranteed service delivery up to 18,000 feet. These

products are configurable from 128 Kbps up to 960 Kbps and give service

providers the opportunity to sell multiple services using a single product.

Hotwire RADSL (Rate Adaptive DSL) products are applicable for both

asymmetric and symmetric applications. The 1 Mbps symmetric operation is

ideal for traditional business applications while the 7 Mbps downstream with

1.1 Mbps upstream asymmetric operation provides added bandwidth for

corporate Internet access. RADSL products can also save line costs by

optionally supporting simultaneous data and voice over the same line.

1. Introduction to Hotwire DSL Routers

Typical DSL Router System

DSL is a local loop technology that uses standard twisted-pair copper wire to

support high-speed access over a single pair of twisted copper wires. DSL

applications are point-to-point, requiring DSL devices at central and end-user

sites.

Hotwire DSL routers interoperate with the following types of Hotwire DSL line

cards, at the DSLAM (Digital Subscriber Line Access Multiplexer) or GranDSLAM

chassis, to deliver applications at high speeds, supporting packet services over a

DSL link:

„

Hotwire 8303 or 8304 IDSL Cards interoperate with two Hotwire IDSL Routers:

— Hotwire 6301 IDSL Router with one Ethernet port

— Hotwire 6302 IDSL Router with a 4-port Ethernet hub

„

Hotwire 8343 or 8344 SDSL Cards interoperate with two Hotwire Symmetric

DSL Routers:

— Hotwire 6341 SDSL Router with one Ethernet port

— Hotwire 6342 SDSL Router with a 4-port Ethernet hub

„

Hotwire 8312 or 8314 ReachDSL Cards interoperate with the Hotwire 6351

ReachDSL Router with one Ethernet port

Hotwire 8510, 8373, and 8374 RADSL Cards interoperate with the Hotwire

6371 RADSL Router with one Ethernet port

Accessing the DSL Router

Access Control to the DSL Router

The Hotwire DSL Router can be managed from an NMS using SNMP or from the

Command Line Interface (CLI). There are several methods available for accessing

the command line interface:

„

Local access at the DSL router through the Console port.

Access by a Telnet session (controlled through the management interface at

the Hotwire chassis).

„

For the Hotwire 6351 ReachDSL Router, access by a Telnet session from the

service domain.

The Hotwire DSL Router accepts only one login session at a time.

Levels of Access

There are two levels of privileges on the Hotwire DSL system:

„

Administrator. The Administrator has two levels of access to the DSL router.

— Administrator, non-configuration mode: Provides read-only capabilities.

This is the same level of access as Operator.

— Administrator, configuration mode: Provides complete write access to the

DSL router.

Operator. The Operator has read-only access to display device information

with no modification permission and no access to management functions.

Refer to Appendix A, Command Line Interface, for access level details for each

command line entry.

For local console access, the Operator and Administrator have the same Login ID,

but with different passwords for their access level. For Telnet access through the

service domain for the ReachDSL Router, up to four login/password/access level

combinations can be configured.

2. Accessing the DSL Router

Local Console Access

Your user account can be configured with one user login name and different

passwords for accessing a CLI session. The DSL router ships with the local

console enabled. After login, the local console can be disabled.

„

To disable with the local console, type:

console disable

save

exit

Press Enter after each command that you type.

Entering console disableresults in NO local access to the DSL router. If

you attempt to log in, you will receive an error message.

After saving this change and ending the session, there is no local access

through the console port. Any access must be through a Telnet session or

the NMS.

„

To determine via a Telnet session whether a console is enabled, enter:

show console

One of the following messages is returned:

— console enabled– Command line management is available at the

console.

— console disabled– No command line management is available at the

console.

Changing Access Session Levels

„

To change the Administrator access level, enter:

admin enable

This command provides Administrator access privileges. The router responds

with a prompt to enter the password for Administrator access.

„

To end the Administrator access level, enter:

admin disable

This command ends the Administrator session. No password is needed.

Entering exithas the same result. Refer to Exiting from the System on

page 2-7 for further details on ending a session.

Telnet Access

Telnet access through the management interface in the DSLAM is always enabled

and defaults to Administrator level. For information on accessing the router

through the MCC card in the DSLAM, see the Hotwire Management

Communications Controller (MCC) Card, IP Conservative, User’s Guide.

For the Hotwire 6351 ReachDSL Router, Telnet access from the service domain is

allowed. Telnet Login and a user name and password should be configured if

Telnet access is enabled on the router (the factory default is disable). Up to four

access level/login/password combinations can be configured for the service

domain from which the ReachDSL Router will accept Telnet connections when the

Telnet login feature is enabled.

NOTE:

For network security, Telnet access in the service domain should be disabled

after the the initial remote configuration unless a firewall or some other

security mechanism is used at the subscriber management system. This

ensures that Telnet access to the endpoint is limited to the service provider.

Configuring the DSL Router

DSL Router Configuration Overview

Hotwire DSL Routers support various customer premises distribution networks

that contain IP forwarding devices or routers, as well as locally attached hosts

or subnets. The Hotwire DSL Router’s IP Routing Table contains IP address and

subnet mask information.

The DSL router supports Internet Protocol, as specified in RFC 791, and Internet

Control Message Protocol (ICMP), as specified in RFCs 792 and 950. It acts as a

router (or gateway), as defined in RFC 791. It also acts as a bridge, bridging all

traffic in the service domain, or routing IP traffic and bridging all other traffic in the

service domain, without affecting traffic in the management domain.

For more information on supported RFCs, refer to Appendix C, Traps and MIBs.

The DSL Router’s Interfaces

Hotwire DSL Routers have two interfaces: the DSL interface and the Ethernet

interface.

„

DSL Interface

The router’s interface type is determined by its model number:

— Models 6301 and 6302 are Hotwire IDSL Routers.

— Models 6341 and 6342 are Hotwire SDSL Routers.

— Model 6351 is the Hotwire ReachDSL Router.

— Model 6371 is the Hotwire RADSL Router.

The DSL interface has a unique MAC address, assigned before the router is

shipped.

3. Configuring the DSL Router

„

Ethernet Interface

— The Ethernet interface is a 10/100BaseT interface that automatically

negotiates the rate to be used, 10 Mb or 100 Mb. If all Ethernet-attached

devices are capable of operating at 100 Mb, the router defaults to 100 Mb.

Otherwise, it operates at 10 Mb.

— The interface can be configured for either DIX or IEEE 802.3 frame format.

When configured to use IEEE 802.3 format, SNAP encapsulation is used,

as specified in RFC 1042.

— The interface has a unique MAC address, assigned before the router is

shipped.

— Hotwire 6302 IDSL and 6342 SDSL Routers have a hub configuration

(separate pins for input and output) with four Ethernet connectors. The

hub acts as a bit-level repeater, with the four Ethernet interfaces logically

appearing as one Ethernet communications interface with a single

collision domain.

— In router mode, the router only accepts transmissions on the Ethernet

interface with the interface’s MAC address, or a broadcast or multicast

MAC address.

— In bridge mode, the router accepts all transmissions. This is the default

setting.

Interface Identifiers

The following conventions are used for naming router interfaces:

„

dsl1 (or d0) – Identifier for the DSL interface.

eth1 (or e0) – Identifier for the Ethernet interface.

With exception to primary status, an interface cannot be deleted or changed as

long as there is a declared route that uses the interface.

Service Domain IP Address Assignments

Hotwire DSL Routers support multiple service domains.

„

Service domains are defined by the configured network addresses and subnet

masks using the CLI.

Up to four service domain IP addresses and subnet masks can be assigned to

each DSL (dsl1) or Ethernet (eth1) interface.

When a numbered interface is designated as the primary interface, that interface’s

IP address is used as the Router ID. If no interface is designated as the primary

interface, the last numbered interface that was created becomes the Router ID.

3. Configuring the DSL Router

Numbered DSL or Ethernet Interface

In this scenario, the hosts attached to the DSL router’s Ethernet interface are on a

different logical network than the core router. The DSL router is the next hop router

for the hosts. The DSL router’s upstream next hop router is the core router.

Simplified Network Topology

Core

Router

DSL

Router

Host

(End Users)

99-16609

Hosts can be assigned IP addresses on the network attached to the DSL router’s

Ethernet interface either statically or dynamically using DHCP. The upstream next

hop router is assigned an address on a different logical network than the hosts.

To configure the router’s interfaces using this scenario, you must:

„

Enable routing on the DSL router.

Assign an IP address to the Ethernet interface, eth1.

Assign an IP address to the DSL interface, dsl1.

Assign an upstream next hop router (not necessary necessary when using

FUNI/MPOA DSL link encapsulation or when the PPPoE client is enabled).

Unnumbered DSL Interface

In this LAN extension application scenario, hosts connected to a corporate

network for virtual office connections or telecommuters want to look like they are

on the same network as the core router. The core router is the next hop router

for the hosts and is on the same logical network as the hosts. This is not the

same as enabling Bridging mode.

To configure the router’s interfaces for this scenario, you must:

„

Enable routing on the DSL router.

Assign an IP address to Ethernet interface (eth1).

Specify the DSL interface (dsl1) as unnumbered.

Assign an upstream next hop router (not necessary necessary when using

FUNI/MPOA DSL link encapsulation or when the PPPoE client is enabled).

„

Enable Proxy ARP for both the eth1 and dsl1 interfaces (not necessary to

enable Proxy ARP on the dsl1 interface when using FUNI/MPOA DSL link

encapsulation or when the PPPoE client is enabled).

3. Configuring the DSL Router

IP Routing

Hotwire DSL Routers use destination-based routing for downstream traffic. An IP

Routing Table is maintained to specify how IP datagrams are forwarded

downstream. The DSL Router is capable of supporting static routes configured by

the user. This table can be viewed by both Operator and Administrator access

levels.

The DSL router uses source-based forwarding for upstream traffic to ensure that

packets are forwarded to the upstream router specified for the configured service

domain.

Refer to Chapter 4, DSL Router Configuration Examples, for further details.

IP Options Processing

The DSL router handles and processes IP datagrams with options set as

described below. No command is available to set IP options.

The router does not process (and drops) any IP datagrams with the following IP

options:

„

Loose source and record route (type 131)

Strict source and record route (type 133)

Security (type 130)

Stream ID (type 136)

The router does process IP datagrams with the following IP options, but does not

provide its IP address or timestamp information in the response message:

„

Record route (type 7)

Timestamp (type 68)

„

Address Resolution Protocol (ARP)

Address Resolution Protocol, as specified in RFC 826, is supported in the router.

Up to 265 ARP Table entries are supported, and a timeout period for complete and

incomplete ARP Table entries can be configured.

NOTE:

ARP is not available on the DSL interface when PPPoE is enabled for the

ReachDSL Router.

ARP requests and responses are not processed on the DSL interface when the

interface is configured to support RFC 1483 PDU routing (Standard mode). Refer

to Routed vs. Bridged PDUs on page 3-13 for more information.

3. Configuring the DSL Router

Operating mode (Standard or VNET) can be changed without reconfiguration of

the router. Static ARP entries can be configured, regardless of the current

operating mode. If static ARP entries are configured, they remain in the database

and can be displayed using the show arpCLI command.

Using CLI commands, you can:

„

Create up to 64 static ARP Table entries.

Display the ARP Table.

Delete ARP Table entries.

Display and delete automatically added ARP Table entries made by the DHCP

server and relay functions. Refer to Dynamic Host Configuration Protocol

(DHCP) Server on page 3-9.

Proxy ARP

The DSL router supports Proxy ARP. Proxy ARP responses are based on the

contents of the IP Routing Table for service domain traffic. The table must have

entry information that indicates what hosts can be reached on the Ethernet

interface, including hosts for which the router will not forward packets because of

IP filters. For additional information on filtering, see IP Protocol Type Filtering on

page 3-11.

Proxy ARP is not available on the DSL interface when the router is configured to

support RFC 1483 PDU routing. See Routed vs. Bridged PDUs on page 3-13 for

more information.

If an ARP request is received on one interface, and the requested IP address can

be reached on the other interface, the router responds with its own MAC address.

Using CLI commands, you can enable and disable Proxy ARP for each interface.

NOTES:

— When Basic NAT is enabled, the DSL interface (dsl1) must have Proxy

ARP enabled when the dsl1 interface address is part of the Basic NAT

global IP network address.

— Proxy ARP is not available on the DSL interface when PPPoE is enabled

for the ReachDSL Router.

— When IP Passthrough is enabled, the Ethernet interface (eth1) must have

Proxy ARP enabled.

3. Configuring the DSL Router

Network Address Translation (NAT)

The DSL router provides NAT, as described in RFC 1631, IP Network Address

Translator (NAT). NAT allows hosts in a private (local) network to transparently

access the external (public or global) network using either a block of public IP

addresses (Basic NAT) or a single IP address (NAPT). Static mapping enables

access to selected local hosts from outside using these external IP addresses.

NAT is used when a private network’s internal IP addresses cannot be used

outside the private network. IP addresses may be restricted for privacy reasons, or

they may not be valid public IP addresses.

Simultaneous Basic NAT and Network Address Port Translation (NAPT) is

supported. Refer to Simultaneous Basic NAT and NAPT on page 3-8 for additional

information.

Basic NAT

Basic NAT allows hosts in a private network to transparently access the external

network by using a block of public addresses. Static mapping enables access to

selected local hosts from the outside. Basic NAT is often used in a large

organization with a large network that is set up for internal use, with the need for

occasional external access.

Basic NAT provides a one-to-one mapping by translating a range of assigned

public IP addresses to a similar-sized pool of private addresses (typically from the

10.x.x.x address space). Each local host currently communicating with a external

host appears to have an unique IP address.

„

IP addresses

A total of 256 IP addresses can be allocated for use with Basic NAT. Two IP

addresses are reserved, and 254 IP addresses are available for use. Up to

64 static mappings can be configured.

Network Address Port Translation (NAPT/PAT)

NAPT allows multiple clients in a local network to simultaneously access remote

networks using a single IP address. This benefits telecommuters and SOHO

(Small Office/Home Office) users that have multiple clients in an office running

TCP/UDP applications. NAPT is sometimes referred to as PAT (Port Address

Translation).

NAPT provides a many-to-one mapping and uses one public address to interface

numerous private users to an external network. All hosts on the global side view

all hosts on the local side as one Internet host. The local hosts continue to use

their corporate or private addresses. When the hosts are communicating with

each other, the translation is based on the IP address and the protocol port

numbers used by TCP/IP applications.

3. Configuring the DSL Router

Simultaneous Basic NAT and NAPT

Simultaneous Basic NAT and NAPT (or PAT) is supported. In this mode, the

servers (private IP addresses) using Basic NAT are configured and the devices

(private IP addresses) using NAPT are optionally configured (static mappings). If

not configured, the remaining private IP addresses default to NAPT.

Enabling Basic NAT does not disable NAPT. When both Basic NAT and NAPT are

enabled, Proxy ARP can also be enabled, although it is only used for Basic NAT.

Applications Supported by NAT

The DSL routers support the following applications and protocols:

„

FTP

HTTP

Ping

RealPlayer

Telnet

TFTP

3. Configuring the DSL Router

Dynamic Host Configuration Protocol (DHCP) Server

The router provides a DHCP Server feature, as specified in RFC 2131, Dynamic

Host Configuration Protocol, and RFC 2132, DHCP Option and BOOTP Vendor

Extensions. DHCP is the protocol used for automatic IP address assignment.

DHCP setup considerations:

„

The range of IP addresses to be used by the DHCP server must be

configured. The maximum number of clients is 256.

The DHCP server is not activated until one IP address and subnet mask are

assigned to the Ethernet interface and routing is enabled.

The DHCP server must be enabled, and the DHCP server and DHCP relay

functions cannot be enabled at the same time.

When the DHCP IP address range is changed, all binding entries,

automatically added routes, and ARP Table entries for the clients configured

with the old address range are removed.

„

When the DHCP Server is enabled, there can be only one IP address

configured for the service domain (Ethernet interface).

The IP address for the next hop router provided to the hosts in the DHCP reply

must be configured.

The subnet mask can be configured along with the IP address range

(optional).

„

The DHCP server domain name can be configured (optional).

The Domain Name Server (DNS) IP address can be configured (optional).

A minimum and maximum lease time setting can be configured.

For additional information, refer to Chapter 4, DSL Router Configuration

Examples.

3. Configuring the DSL Router

DHCP Relay Agent

The router provides the capability of serving as a DHCP Relay Agent, as specified

in RFC 2131, Dynamic Host Configuration Protocol. The router provides the

capability to enable and disable the DHCP Relay Agent and to configure the IP

address of the DHCP server to which the DHCP requests are to be forwarded.

The DHCP server assigns an IP address to the end-user system. When DHCP

Relay is enabled, it is possible to limit the number of DHCP clients. The IP Routing

Table and ARP Table are automatically updated. The DHCP relay agent in the

router should be used when there is a DHCP server upstream in the service

domain.

DHCP relay agent setup considerations include the following:

„

DHCP server IP address must be configured.

DHCP relay and routing must be enabled; that is, both the server address and

the interface closest to the server are configured.

„

The number of DHCP clients can be limited to 1–256.

DHCP server and DHCP relay functions cannot be enabled at the same time.

NAT and DHCP relay cannot be enabled at the same time.

3. Configuring the DSL Router

Security

The router offers security via the following:

„

Filtering. A filter consists of a set of rules applied to a specific interface to

indicate whether a packet received or sent on that interface is forwarded or

discarded. Filters are applied to traffic in either the inbound (from the Ethernet

port) or outbound (from the DSL port) direction on that interface:

— IP Protocol Type: TCP, UDP, or ICMP

— ICMP Message Type, Code

— TCP/UDP Ports

— Source/Destination IP Address

— Ethernet Type

„

Always enabled:

— Land Bug Prevention

— Smurf Attack Prevention

NOTE:

All Hotwire DSL Router filters are configured on the Hotwire DSL card. Some

routing parameters that affect filtering, such as enabling bridging or routing,

can only be configured on the DSL router.

IP Protocol Type Filtering

By default, IP Protocol Type (IP) filtering is disabled on the Hotwire DSL card for

the DSL router. If enabled, filtering provides security advantages on LANs by

restricting traffic on the network and hosts based on the source and/or destination

IP addresses.

There is one filter per direction, with a maximum of 33 rules per filter. For IP filters,

all filter access rules with a source host IP address are applied first, with all rules

with a destination host IP address applied next. The remaining filters are applied in

the order in which they were configured.

For additional information about IP filtering, refer to the Hotwire MVL, ReachDSL,

RADSL, IDSL, and SDSL Cards, Models 8310, 8312/8314, 8510/8373/8374,

8303/8304, and 8343/8344, User’s Guide.

3. Configuring the DSL Router

Ethernet Type Filtering

Ethernet Type filtering (Ethertype) does not apply when the DSL router is in

router-only mode. By default, Ethertype filtering is disabled on the Hotwire DSL

card for the DSL router. If enabled, separate Ethertype filters are applied to the

Ethernet and/or DSL interface with one filter per interface direction. There is a

maximum of 16 rules per list. Each rule access list allows filtering of a single

Ethertype or a range of Ethertypes.

MAC frames can be filtered based on the:

„

SNAP Ethernet field in the 802.3 header.

Protocol type field in the DIX Ethernet header.

For Ethertype filters, the rules are applied in the order in which they were

configured. For additional information about Ethertype filters, refer to the Hotwire

MVL, ReachDSL, RADSL, IDSL, and SDSL Cards, Models 8310, 8312/8314,

8510/8373/8374, 8303/8304, and 8343/8344, User’s Guide.

Land Bug/Smurf Attack Prevention

Land Bug and Smurf Attack prevention are enhanced firewall features provided

by the router.

„

Land Bug – The router drops all packets received on its DSL or Ethernet

interface when the source IP address is the same as the destination IP

address. This prevents the device from being kept busy by constantly

responding to itself.

„

Smurf Attack – The router does not forward directed broadcasts on its DSL

and Ethernet interfaces, or send an ICMP echo reply to the broadcast

address. This ensures that a legitimate user will be able to use the network

connection even if ICMP echo/reply (smurf) packets are sent to the broadcast

address.

3. Configuring the DSL Router

Routed vs. Bridged PDUs

The router supports both the VNET model and 1483 Routed model (derived from

RFC 1483) for the transportation of PDUs (Protocol Data Units) from the DSL

router to the router in the core network. When operating in Standard mode, the

DSL router in conjunction with the DSL line card with an ATM uplink (for example,

Model 8304, 8344, etc.) supports routed PDUs. When operating in VNET mode,

the DSL router in conjunction with the DSL line card with an ATM uplink supports

bridged PDUs only.

NOTE:

Standard mode vs. VNET mode is configured on the DSL card at the

DSLAM/GranDSLAM chassis by changing the link encapsulation on the DSL

port.

Both ends of the network (e.g., the DSL router and the DSL line card and the core

router) must be configured to operate the same way (i.e., routed or bridged).

PPPoE Client Support

The Hotwire 6351 ReachDSL Router supports a PPPoE client as defined in

RFC 2516, allowing PPPoE functionality to be moved from the PC clients to the

ReachDSL Router. See PPPoE Client Commands in Appendix A, Command Line

Interface, for information on configuring PPPoE client support.

PPPoE client support can only be enabled on the Hotwire 6351 ReachDSL Router

when:

„

The router is configured for IP Routing (bridging must be disabled),

The router must be in VNET mode,

Proxy ARP for the DSL interface must be disabled, and

No upstream next-hop route should be defined for the DSL interface.

In addition to using the CLI to enable PPPoE support, the CLI can be used to

specify the interface to assign the IP address negotiated during the network-layer

protocol phase of PPP (the default is the DSL interface).

3. Configuring the DSL Router

When the negotiated IP

address is assigned to the . . . Then . . .

Ethernet interface of the

ReachDSL Router

The DSL interface will automatically be configured as

unnumbered, and any IP address(es) previously

assigned to the Ethernet and DSL interfaces are

removed. A route for the subnet defined by the

negotiated IP address assigned to the Ethernet interface

will automatically be added to the IP routing table.

DSL interface of the

ReachDSL Router

Any IP address(es) previously assigned to the DSL

interface are removed. The IP address(es) assigned to

the Ethernet interface are left intact unless they conflict

with the negotiated IP address. The IP address used by

the Ethernet interface must be assigned by the user.

DSL interface of the

ReachDSL Router using the

IP Passthrough feature

The negotiated IP address is assigned to the DSL

interface of the DSL Router and served to a passthrough

device on the LAN interface via DHCP. Any IP address

previously assigned to the DSL interface is removed. Any

IP address assigned to the Ethernet interface is left intact

(unless it conflicts with the negotiated IP address). The IP

address used by the Ethernet interface must be assigned

by the user.

Once the PPP-negotiated IP address is assigned, the ReachDSL Router’s

configuration database will automatically be converted to a new configuration

determined by this IP address and the interface to which it is assigned. However,

any changes made to the interface assignment for the PPP-negotiated IP address

do not take effect until the next time the PPP link is established. This new

configuration will result in the following:

„

The DSL and/or Ethernet interface(s) are reconfigured.

Routes associated with any interfaces that have been removed are deleted.

An exception to this is when the negotiated IP address is assigned to the

Ethernet interface and the subnet defined by the interface’s IP address is the

same as the one defined by the negotiated IP address.

„

All dynamic ARP entries are removed. All static ARP entries associated with

the DSL interface and any removed interfaces are deleted. Static ARP entries

for the Ethernet interface are retained if the negotiated IP address is assigned

to the Ethernet interface and the subnet defined by the interface’s IP address

is the same as the one defined by the negotiated IP address.

„

The negotiated IP address automatically becomes the primary IP address and

the NAPT public IP address.

An active service domain Telnet session is terminated if the interface

associated with the session is removed or the IP address of the interface is

changing.

„

All DHCP bindings and BOOTP Relay Agent snoop information are removed if

the subnet defined by the Ethernet IP address changes. If the new Ethernet IP

address is still in the same subnet, then only the binding and snoop

information that conflicts with this IP address is removed.

If the IP Passthrough feature is used, the DHCP Server feature is

automatically enabled and the negotiated IP address is the only IP address

served. In addition, the derived subnet mask, discovered peer IP address, and

negotiated DNS server addresses (unless explicitly directed not to use the

DNS addresses) are configured as the DHCP options provided to the client.

In this basic routing example:

„

There are multiple clients with statically assigned public IP addresses

configured on the Ethernet side of the DSL router.

The IP addresses of the clients are contained within the subnet specified by

the configured Ethernet IP address and subnet mask.

The next hop router (default gateway) of the clients is the Ethernet interface

(eth1) of the DSL router.

The next hop router for downstream forwarding from the core router is the DSL

interface (dsl1) of the DSL router.

The commands and syntax for this example are:

ip routing enable

ifn address eth1 155.1.3.254 255.255.255.0

ifn address dsl1 155.1.4.254 255.255.255.0

— FUNI/MPOA (1483 routed) link encapsulation can be used with this

configuration and the DSL card Models 8304, 8314, 8344, and 8374. Link

encapsulation is configured on the DSL port. This link encapsulation must

match the core network encapsulation type. The ip route create

upstreamcommand is not necessary when using FUNI/MPOA link

encapsulation.

— If IP Scoping is enabled, the clients’ IP addresses must be entered into the

client VNID table.

Simultaneous Basic NAT and NAPT Configuration Example

The DSL router can be configured for Basic NAT and NAPT simultaneously. In the

private address space, multiple work stations can use NAPT and the servers can

use Basic NAT. This allows a server to support traffic other than TCP/UDP traffic

and accommodate multiple inbound traffic types. Using Basic NAT also allows you

to have multiple servers of the same type (Web, FTP, Telnet) on the private

network. All private addresses not specified in a Basic NAT map command will be

translated via NAPT.

The clients, the DSL router’s Ethernet interface, and the core router’s interface

are all on the same logical network.

„

If IP Scoping is enabled at the DSL card, the eth1 and the client’s IP

addresses must be placed in the client VNID table (VNID mode must be

selected on the DSL cards with an ATM uplink, such as Model 8304, 8344,

etc.).

The commands and syntax for this example are:

NOTES:

— The ip routing enablecommand is only required when using

firmware version 4.2.5 or higher.

— FUNI/MPOA (1483 routed) link encapsulation can be used with this

configuration and the DSL card Models 8304, 8314, 8344, and 8374. Link

encapsulation is configured on the DSL port. This link encapsulation must

match the core network encapsulation type. The ip route create

Device Restart

Alarms Inquiry

The DSL router can be restarted locally or remotely. From the CLI, type Restart

and press Enter.

The router reinitializes itself, performing a power-on self-test and resetting the

local System Log (SYSLOG).

The DSL router’s front panel includes an Alarm (ALM) LED to alert you to alarm

conditions. The alarm(s) detected can be viewed using the show alarmsCLI

command.

See show alarm s on page A-24 in Appendix A, Command Line Interface, for

information about the command and what is displayed when the command is

entered.

6. Diagnostics and Troubleshooting

System Log

The router can log significant system events (SYSLOG). The SYSLOG can be

maintained locally on the router and can also be sent to a remote SYSLOG server.

To activate:

„

The router must be configured to enable the output of SYSLOG messages via

the syslog enable command.

The Management Controller Card (MCC) always has SYSLOG enabled.

An IP address (loopback or remote) must be supplied.

„

The SYSLOG can also be captured by a remote SYSLOG server running the

UNIX daemon syslogd or an equivalent program. It is necessary to know the

IP address where the syslogd resides and the UDP port number the syslogd is

using.

The advantage of using a remote SYSLOG server is that ALL events will be

maintained upon restart of the router. The local SYSLOG is cleared upon

restart.

Events are classified by severity level and the system administrator can specify the

minimum severity to be logged.

Table 6-1. SYSLOG Commands (1 of 2)

show syslog

Minimum Access Level: Operator

Command Mode: Standard

Shows whether the current status of system as enabled or disabled. The severity level, IP

address, domain, and User Datagram Protocol (UDP) port are displayed.

syslog {enabled | disabled}

level {emer | err | norm | info}

ip-addr x.x.x.x

domain {management | service}

port nnn

syslog {enable| disable}

Minimum Access Level: Administrator

Command Mode: Config

Enables or disables SYSLOG output. When enabling SYSLOG, the SYSLOG IP address

must be entered (next command) and saved.

enable – Enables SYSLOG output.

disable – Disables SYSLOG output so no system log entries are sent.

ip-addr – The IP address for SYSLOG. The loopback address of 127.0.0.1 can be used to

have the functionality of the SYSLOG (entries kept locally).

mgt – The IP address resides in the management domain. This is the default setting.

srvc – The IP address resides in the service domain.

syslog port [port-number]

Minimum Access Level: Administrator

Command Mode: Config

Specifies the User Datagram Protocol (UDP) port number on the server to which the

system events will be sent.

port-number – The UDP port number. The default is 514.

syslog level level

Minimum Access Level: Administrator

Command Mode: Config

Specifies the minimum severity level to be logged. Refer to T a ble 6-2, SYSLOG

Messages, for a list of messages by their severity level.

level – The minimum level to be logged. The default is NORM.

The choices for severity level (displayed as high severity to low severity) are as follows:

EMER – emergency, the system is unusable

ERR – error conditions reported

NORM – normal or administrative reporting

INFO – informational reporting

Example: To log EMER and ERR severity levels, type syslog level ERRand press

Enter.

show log [number ]

Minimum Access Level: Administrator

Command Mode: Config

Displays the contents of the local system error log. (The 100 most recent SYSLOG entries

are kept locally.) The user specifies how many entries they wish to view. Entries are

displayed in reverse order from most recent to oldest.

number – The number of local entries to be seen. The default is 10; the range is 1–100.

NOTE: The locally retained SYSLOG will be reset at the router if the restart

command is issued. External logs are retained after a router restart.

Ping

The Ping program is an IP-based application used to test reachability to a specific

IP address by sending an ICMP echo request and waiting for a reply. A Ping can

test upstream or downstream connectivity.

Table 6-3. Ping Command

ping dest-ip [mgt| -x source-ip] [-l bytes] [-w time] [-i{eth1| dsl1}]

Command Mode: Standard

Pings the specified destination IP address. Once Ping starts, the input prompt does not

redisplay until the Ping is finished or aborted with Ctrl-c.

Example: ping 135.300.41.8 –l 144 –w 30 -i eth1

dest-ip – The destination IP address of the device to ping.

mgt – Specifies that the IP address is in the management domain (through the MCC). The

mgt designation cannot be entered unless you have Administrator access level. Do not

use this designation with the –xsource-ip selection.

6. Diagnostics and Troubleshooting

TraceRoute

The TraceRoute program is an IP diagnostic tool that allows you to learn the path

a packet takes from the service domain local host to its remote host.

If you are unable to ping a device in a Hotwire network configuration, you may

want to run a TraceRoute to identify the link (destinations up to 64 hops) between

the router and the device that is not forwarding the Ping message.

Table 6-4. TraceRoute Command

traceroute dest-ip [-x source-ip] [-l bytes] [-w time] [-h hops]

[-i { eth1ꢀ_ꢀꢀdsl1}]

Minimum Access Level: Operator

Command Mode: Standard

Performs TraceRoute to the specified destination IP address. Once TraceRoute starts, the

input prompt will not redisplay until TraceRoute finishes or is aborted with Ctrl-c.

Example: traceroute 135.300.41.8 –w 60 -i eth1

dest-ip – The destination IP address for TraceRoute.

source-ip – The source IP address used. The default source address is from the service

domain in which the test is being done. The IP address is validated to verify that it is an

interface IP address.

bytes – Bytes of data (l = length). The default is 64 bytes; the range is 0–15,000.

time – Time (in seconds) before the TraceRoute is abandoned. The default is 10 seconds;

the range is 0–60.

hops – Decimal number that specifies the maximum number of hops to be tested. The

default is 8; the range is 0–128.

interface – Specifies the target interface for the command. Do not use with the

–xsource-ip selection.

eth1 – Ethernet interface

dsl1 – DSL interface

Command Line Interface

Command Line Interface Capability

The Hotwire DSL router is managed with text commands from the Command Line

Interface (CLI). The CLI can be accessed:

„

Locally with an ASCII terminal connected to the Console port, or

Remotely via a Telnet session (through the management interface or from the

service domain).

The CLI is ASCII character-based and provides the capability to:

„

Display the syntax of commands.

Change the operational characteristics of the router by setting configuration

values.

„

Restore all configuration values to the initial factory default settings.

Display the router’s hardware and identification information.

Display system status, including DSL link and Ethernet status.

Display a sequence of commands that will set all configurable parameters to

their current value.

Refer to Appendix B, Configuration Defaults and Command Line Shortcuts.

A. Command Line Interface

Navigating the Router’s CLI

The Hotwire DSL router’s CLI uses the following keys (as do most terminal

emulation programs):

„

Enter or Return – Accepts the input.

Ctrl-c – Aborts the entry or clears the input line.

Down Arrow – Repeats an entry within the last five entries made.

Up Arrow – Displays the last entry.

Left Arrow – Moves the insertion point one space to the left.

Right Arrow – Moves the insertion point one space to the right.

Command Recall

The router keeps a history of the last several commands entered on the CLI. For

example, if you press the Up Arrow key, the most recently entered command

appears on the command line, where it can be edited and reentered by pressing

Enter. If you press the Up Arrow key again, the next most recent command

appears, etc.

After pressing the Up Arrow key one or more times, pressing the Down Arrow key

moves down the list of recent commands, wrapping past the end of the list in either

direction.

Commands appearing in the command line can be edited. Use the Left and Right

Arrow keys to move the insertion point, enter the new characters or use the Delete

key to delete the character just to the left of the insertion point.

Syntax Conventions

The following conventions are used in command line syntax throughout this

manual. With the exception to the Login ID and Password, the CLI is not

case-sensitive.

Convention

Translation

Square brackets represent an optional element.

Braces represent a required entry.

Vertical bar separates mutually exclusive elements.

Minimum Access Level: Administrator

Command Mode: Config

Specifies the IP address associated with either the Ethernet or DSL interface.

Examples: ifn address dsl1 135.300.41.8 255.255.255.0

ifn dsl1 primary

Up to four (4) IP addresses can be assigned on each interface. An interface address and

mask cannot be changed while there is a static route (upstream or downstream) that uses

it. Interface IP address ranges must not overlap.

eth1, eth1:1, eth1:2, eth1:3, eth1:4 – Ethernet interface (eth1 is the same as eth1:1).

dsl1, dsl1:1, dsl1:2, dsl1:3, dsl1:4 – DSL interface (dsl1 is the same as dsl1:1).

ip-address – The IP address associated with the specified interface.

mask – The subnet mask associated with the specified IP address.

primary – The Primary designation of a numbered interface marks that interface as the

one whose IP address will be used as the Router ID. (The Router ID is important when the

DSL interface is unnumbered.) If no interface is defined as Primary, the last numbered

interface created will become the Primary IP Address.

unnumbered – Specifies that the DSL interface is to be unnumbered.

NOTES:

– For each defined Ethernet interface, a corresponding upstream next hop router IP

address must be configured for routing of packets received on that interface, unless

FUNI/MPOA link encapsulation is being used or PPPoE is enabled. See ip route

create upstream eth1[:ifn] next-hop-i p on page A-8 for more details.

– When the eth1 is assigned an IP address, this section also defines the logical

network (subnet) containing the locally attached hosts. An IP route table entry will

automatically be created to correspond to the subnet defined by the mask.

– When the DSL interface is numbered, multiple logical Ethernet interfaces can be

assigned to the same DSL logical interface by configuring the same upstream next

hop router. This is not necessary if FUNI/MPOA link encapsulation is being used or

PPPoE is enabled.

– The configured DSL logical interfaces must be either all numbered or a single

unnumbered interface.

– When NAT is being used, the DSL interface must be numbered.

– When NAT, DHCP Server, or DHCP Relay is enabled, there can be only one service

domain configured. Only one logical interface must be defined for each physical

interface, i.e., one IP address to each interface.

A. Command Line Interface

PPPoE Client Commands

PPPoE Client commands are supported only for the Hotwire 6351 ReachDSL

Router, and only when the router is configured for IP routing (bridging must be

disabled) and is operating in VNET mode. See PPPoE Client Support in

Chapter 3, Configuring the DSL Router for more information.

Table A-13. PPPoE Client Commands (1 of 3)

pppoe {enable| disable}

Minimum Access Level: Administrator

Command Mode: Config

Enables or disables PPPoE client support in the service domain.

enable – Enable PPPoE client support in the service domain. When the PPPoE client is

enabled, Proxy ARP for the DSL interface must be disabled and no upstream next hop

routers should be defined for the DSL interface.

disable – PPPoE client support is not available. This is the default setting.

ppp ip {eth1| dsl1| passthrough} [mask] [no-dns]

Minimum Access Level: Administrator

Command Mode: Config

Specifies the interface to assign the PPP negotiated IP address for the ReachDSL Router.

The IP address is negotiated during the network-layer protocol phase of PPP.

NOTE: This IP address is retained through a power reset and does not cause the

ReachDSL Router to reset. However, a change to this option does not take effect until

the next PPP link establishment. At that time, the new configuration determined by this

IP address and its assigned interface will overwrite the current configuration.

eth1 – The negotiated IP address will be assigned to the Ethernet interface of the

ReachDSL Router. The DSL interface will then be automatically configured as

unnumbered, and any IP address previously assigned to the Ethernet and DSL interfaces

is removed. A route for the subnet defined by the negotiated IP address assigned to the

Ethernet interface will automatically be added to the IP routing table.

NOTE: An attempt to assign the negotiated IP address to the Ethernet interface when

NAT is enabled will be rejected since the DSL interface must be numbered when NAT

is enabled.

dsl1 – The negotiated IP address will be assigned to the DSL interface of the ReachDSL

Router. Any IP address previously assigned to the DSL interface is removed. Any IP

address assigned to the Ethernet interface remains intact unless there is a conflict with

the negotiated IP address. IP address assignment to the Ethernet interface is the

responsibility of the user when dsl1 is selected. This is the default setting.

passthrough – The negotiated IP address will be assigned to the DSL interface of the

ReachDSL Router and served to a passthrough device on the LAN interface via DHCP.

When the address is assigned to the DSL Router, any IP address previously assigned to

the DSL interface is removed. Any IP address assigned to the Ethernet interface is left

intact (unless it conflicts with the negotiated IP address). IP address assignment to the

Ethernet interface is the responsibility of the user when passthrough is selected.

A. Command Line Interface

Table A-13. PPPoE Client Commands (2 of 3)

ppp ip {eth1| dsl1| passthrough} [mask] [no-dns]

(Continued from previous page)

The passthrough device is selected as the first to broadcast a DHCP DISCOVER. The

DHCP Server feature of the DSL Router will be automatically enabled and the negotiated

IP address will be configured as the range of IP addresses to be served. In addition, the

derived subnet mask (see the description for mask below) and discovered peer IP

address will be configured as the Subnet and Router option values, respectively, provided

by the DHCP server to its clients. Because the DHCP Server is required for passthrough,

selecting this option is restricted by the same mutual exclusion rules that apply to the

DHCP Server feature. For example, since the DHCP Server and the DHCP Relay Agent

features cannot be enabled simultaneously, attempting to select the passthrough option of

this command when the DHCP Relay Agent is enabled will result in rejection of the save

command.

NOTE: Proxy ARP must be enabled on the Ethernet interface for traffic to be properly

forwarded from the passthrough device.

mask – The subnet mask associated with the PPP negotiated IP address. If the mask is

not specified, a mask is calculated that is the longest mask that allows the negotiated IP

address and the IP address of the PPP link peer to reside in the same subnet.

no-dns – The negotiated DNS server address values are not passed to the client when

the DHCP Server feature is enabled. See DHCP Server Commands on page A-14.

ppp authentication{chap| pap| both| none}

Minimum Access Level: Administrator

Command Mode: Config

Specifies the authentication protocol to be negotiated and used in the PPP session. The

ReachDSL Router will always be the authenticated party of this protocol.

NOTES:

– A change to this option does not take effect until the next PPP link establishment.

– To negotiate an authentication protocol, the CHAP host name and secret or PAP

peer ID and password must have already been configured (using the ppp

usernameand ppp passwordcommands), or the negotiation will operate as

though the default setting (none) has been configured.

chap – During the link establishment phase, the ReachDSL Router will accept the

proposed use of the Challenge Handshake Authentication Protocol (CHAP) only.

pap – During the link establishment phase, the ReachDSL Router will accept the

proposed use of the Password Authentication Protocol (PAP) only.

both – During the link establishment phase, the ReachDSL Router will accept the

proposed use of either CHAP or PAP.

none – During the link establishment phase, the ReachDSL Router will not negotiate to

use any authentication protocol nor will it accept the proposed use of one. This is the

default setting.

Traps and MIBs

SNMP Overview

The Simple Network Management Protocol (SNMP) is an application-level

protocol used in network management to gather information from network devices.

Each DSL router runs an SNMP agent that collects data. The network

management station in the NAP domain can exercise all the management

functions remotely from the Network Operations Center (NOC).

There is no discovery of the DSL router, and it does not appear on the

Management Domain map. SNMP security is configured on the MCC card and all

SNMP requests to the DSL router are authenticated at the MCC. The MCC is the

destination for all traps originated by the DSL router.

See the Hotwire Management Communications Controller (MCC) Card, IP

Conservative, User’s Guide for more information on SNMP.

NOTE:

There are several SNMP Sets that result in resetting the DSL router. When

this happens, the NMS that sent the Set command may not receive a

response from the DSL router and will time out. This is not an error.

Traps Overview

Traps inform the NMS of an alert occurring in the system (e.g., threshold

exceeded). Traps are sent at the start and completion of a test or alarm condition.

The MCC is the destination for all traps originated by the DSL router. These traps

are then rebuilt with the trap destination information stored on the MCC and

forwarded to the appropriate trap managers.

Traps are configured via a Telnet session, terminal session, or via SNMP, and are

based on community names. Traps are included in the MIB II, Entity and Hotwire

Enterprise MIB definitions. MIBs can be accessed through the Paradyne Web site

at www.paradyne.com. Select Technical Support → MIBS.

The DSL system can send traps to three IP addressable destinations per

community (for a total of 12 destinations).

MIBs Overview

Standard MIBs

MIB II (RFC 1213)

The Hotwire DSL system supports standard as well as Paradyne Enterprise MIBs.

Various configuration, status, and statistical data within the SNMP agent is

accessible from the NMS. The content of an SNMP agent’s MIBs is defined by

various Internet Request for Comments (RFC) documents.

The following sections provide brief descriptions about supported MIBs. Complete,

up-to-date details about the content of all DSL MIBs are available on the Paradyne

Web site at www.paradyne.com. Select Technical Support → MIBs.

Standard MIBs supported consist of the following:

Firmware Upgrade

Overview

The Hotwire 6351 ReachDSL Router supports a TFTP client for the purpose of

firmware upgrades within the service domain. The Network Service Provider

(NSP) can initiate upgrades for the ReachDSL Router using CLI commands from

the local console or through Telnet access.

Firmware Upgrade Commands

download {dsl1[:ifn]| eth1[:ifn]} server-ip filename

Minimum Access Level: Administrator

Command Mode: Config

Performs a firmware download for the specified interface, TFTP server IP address, and

firmware image filename.

dsl1 [:ifn] – The DSL interface for the TFTP session.

NOTE: The interface must be configured, or the command will be rejected. If an IP

address is configured for the interface, the TFTP client will assume the configured

address. If the DSL interface is unnumbered, the TFTP client will assume the IP

address of the Ethernet interface, if one is configured.

eth1 [:ifn] – The Ethernet interface for the TFTP session.

NOTE: The interface must be configured, or the command will be rejected. If an IP

address is configured for the interface, the TFTP client will assume the configured

address.

server-ip – The TFTP server host IP address.

NOTE: The server must be accessible within the service domain and a route must exist

for the TFTP session to become active.

filename – The firmware image file name, 1–31 characters.

NOTE: The filename must match the filename as it exists on the TFTP server.

apply download

Minimum Access Level: Administrator

Command Mode: Config

Provides the capability of activating an alternate firmware image. This command is

typically used following a successful download of a new firmware image.

For example:

download ifn address eth1 155.1.3.254 Paradyne server

3. The command syntax is verified and you are prompted for confirmation:

Downloading will affect user data performance.

Are you sure?

Once you confirm the request, the file transfer begins and you can observe the

following:

— The ALM and TST LEDs alternately flash until the file transfer

completes.

— The symbol ! is displayed on the CLI for every 10 packets received

from the server.

4. Upon completion of the transfer, if the image transferred has the same

firmware version as the image in the target flashbank, the download process is

complete and the final command response is displayed.

If the transferred image is different, the image is programmed to flash memory.

During this programming time (approximately 30 seconds), you can observe

the following:

— The ALM and TST LEDs light.

— User data performance is affected.

After flash programming completes, the ALM LED goes off, and the status of

the checksum calculation, a final information (or error) message, and the file

transfer statistics are displayed:

Accessing TFTP: //server_ip/filename

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

E. Firmware Upgrade

NOTE:

A checksum of the file is calculated and verified prior to programming the

flashbank. However, a checksum of the active flashbank does not occur

until a power-on self-test. If the flashbank was not successfully

programmed, the verification of the checksum image in flash memory will

fail during self-test and the valid image in the alternate bank will be copied

to the active bank.

If the image transferred has the same software revision as the image in the

alternate flashbank, an error message displays and the image is not

reprogrammed into flash. Also, if an error occurs during the file transfer or

flash programming, an error message is displayed.

Procedure

To activate an alternate firmware image following a successful firmware download

of a new firmware image:

1. At the CUSTOMER-CONFIG#> prompt, type:

apply download

2. You are then prompted for a command confirmation:

Applying download will result in a system reset.

Are you sure?

Once you confirm the request, the ReachDSL Router will switch from the

active flashbank to the alternate flashbank, reset the system and execute the

new image. The following message is displayed:

System is being reset

However, if the same firmware image exists in both the active and alternate

flashbanks, the unit will not reset and the following message is displayed:

No new firmware to apply
