Hardware Installation

and Network

Topology

Overview

The Intel Express 100BASE-TX Switching Hub is a 5-port Fast

Ethernet switch featuring five 100BASE-TX ports and two slots for

optional 100BASE-TX or 100BASE-FX media adapters. Each 100

Mbps port supports a Fast Ethernet segment, up to a total of 1024

cached nodes for the switch.

The switch increases the available bandwidth and extends the distance

of Fast Ethernet installations by dividing the network into segments

and insulating each from the others’ local traffic. Additionally, by

configuring a link for full duplex, you can establish a 200 Mbps link

between the switch and another switch, server, or workstation. This is

especially useful for busy file servers that are accessed by multiple

segments.

Data transfer delays are eliminated through the switch’s parallel store-

and-forward architecture with direct port-to-port transfer. Selective

flow control improves performance by preventing lost packets due to

buffer overload.

Intel Express 100BASE-TX Switching Hub

Security features include the creation of custom filters and virtual

networks (VLANs). You can define any custom filter based on

multicast/broadcast, source port, destination port, and destination

address. VLAN features include the ability to set broadcast or

multicast domains. See Chapter 2 for information on configuring

VLANs.

The switch also has a built-in SNMP (Simple Network Management

Protocol) agent and can be monitored and controlled through any

SNMP-compliant Network Management System (NMS). See page 20

for information on using the switch with an SNMP NMS and getting

the switch’s MIB (Management Information Base) file.

C H A P T E R 1 Hardware Installation and Network Topology

Installation and Setup

Install the switch in a rack or on a shelf.

For rack placement, connect the switch to a 19-inch rack using the

enclosed rack mount brackets.

For shelf placement, attach the enclosed rubber feet to each corner of

the bottom of the switch and place it on a flat, level surface.

Plug the switch in and turn the power on.

Plug the switch into an active AC outlet and turn the power on. A

built-in power supply automatically adjusts to any outlet providing

between 90 VAC and 264 VAC at 50/60 Hz.

Connect the Fast Ethernet devices.

NOTE

The switch will only work with

100 Mbps devices. For a

10BASE-T connection, see

page 12.

For optimum performance, the Fast Ethernet segments connected to

the switch must be configured carefully. Follow these general

guidelines:

•

Connect only 100 Mbps devices to the switch. The switch will not

work with 10 Mbps devices. See page 12 for information on

connecting to a 10 Mbps segment.

•

Always use Category 5 unshielded twisted-pair (UTP) cable when

plugging devices into 100BASE-TX ports.

Limit the distance between devices connected with UTP cable to

100 meters.

Use a crossover cable when directly connecting a workstation,

server, or another switch to the switch. Use straight-through

cables when connecting to a repeating hub or concentrator.

•

Configure the network so devices that primarily talk to each other

are on the same segment. Each port on the switch is defined as a

single Fast Ethernet segment.

Is setup complete?

If you’re using the switch as a stand-alone device (not under the

control of network management software), you’re done.

If you want to change the default configuration (shown in

Appendix A) or manage the switch, continue to Chapter 2.

Intel Express 100BASE-TX Switching Hub

NOTE

Using the Switch

The default configuration of

all ports is half-duplex mode.

The switch requires minimal user intervention. It automatically learns

the addresses of new stations as they appear, and will relearn

addresses dynamically if the network is reconfigured.

To change to full duplex, use

the Console Manager. See

page 19 for instructions.

Each of the Fast Ethernet ports has six status LEDs. There is a

separate bank of four LEDs for the management status.

Port status LEDs

Port LEDs provide information about the port’s configuration and the

status of devices connected to the ports.

Intel Express 100BASE-TX Switching Hub

Cabling Requirements

Incorrect cabling is often the cause of network configuration

problems. It’s important that you understand cabling requirements

before connecting Fast Ethernet devices to the switch.

UTP requirements

The 100BASE-TX Fast Ethernet specification requires you use

Category 5 (CAT5) unshielded twisted-pair (UTP) cabling to operate

at 100 Mbps per second. If you use lower grade cabling (CAT3 or

CAT4), you’ll get a connection, but will soon experience data loss or

slow performance.

You’re limited to 100 meters between any two devices with UTP

cable. However, you can extend the total diameter by installing a fiber

optic media adapter and using fiber optic connections between

switches, or between the switch and a router or bridge.

See pages 10–11 if you’re unsure whether your network topology

meets these distance limitations.

Fiber optic requirements

The optional 100BASE-FX fiber optic media adapter (Intel product

code ESMODFX) lets you use multimode fiber optic cable to connect

two switches, or to connect the switch with a router or bridge. The

media adapter uses an SC fiber optic connector.

With multimode fiber optic cable, signals can travel up to 412 meters

with no repeater when the link is configured at half duplex. If

configured at full duplex, the signal can travel up to 2 km.

C H A P T E R 1 Hardware Installation and Network Topology

Straight-through vs. crossover cables

Ports on the switch are wired MDI so you can use a straight-through

cable when connecting to a Fast Ethernet repeating hub port, which is

usually wired MDI-X. For direct connection to another MDI port

(workstation, server, or another switch), you must use a crossover

cable. The pinouts of MDI and MDI-X ports are shown below.

Determining which cable to use

Different switch and repeater manufacturers implement their port

configurations differently. The following guidelines are based on the

Intel Express 100BASE-TX Switching Hub (switch), the Intel Express

100BASE-TX Stackable Hub (repeater) and the EtherExpress™

family of adapters (server or workstation). These apply to the majority

of switches and hubs:

Intel Express 100BASE-TX Switching Hub

Connecting to a 10 Mbps segment

The Express Switching Hub is a 100 Mbps-only switch. You can’t

connect a 10 Mbps device directly to the switch.

The preferred way to connect the segments is by using a bridge,

router, or a 100 Mbps uplink module for your 10 Mbps hub (there

isn’t a 10 Mbps uplink module available for the Express switching

hub). However, this is costly if you don’t already have the equipment.

An inexpensive alternative is to connect the segments through a

server.

router software by default.

You can download it from the

site.

Several adapters on the market (such as the Intel EtherExpress PRO/

100 adapter) operate at either 10 or 100 Mbps. By connecting the

Express 100BASE-TX Switching Hub to one server adapter at 100

Mbps and your 10BASE-T hub to a separate adapter at 10 Mbps in the

same server, you can route traffic from the 10 Mbps segment to the

100 Mbps segment through your Network Operating System (NOS).

If your NOS doesn’t support multi-protocol routing (Windows 95

peer-to-peer and Windows for Workgroups* don’t), you must use a

Fast Ethernet switch or router that supports both 10 Mbps and 100

Mbps.

C H A P T E R 1 Hardware Installation and Network Topology

NOTE

By default, flow control is

enabled on all ports.

Excessive flow control problems

During times of peak network usage, you may occasionally see the

FC/FD LED blink (for a description of the LED, see page 6). This is

normal. However, if it stays lit for more than a few seconds at a time,

or if there’s an excessive number of flow controls reported by the

If you configure a port for full

duplex, flow control is auto-

matically disabled.

network management software, it could indicate a problem with your

network configuration.

A port’s FC/FD LED indicator flashes whenever a packet is received

that needs to be forwarded to a port that already has too many packets

queued. This indicates a temporary overload situation on one port; the

total traffic to the port exceeds the amount the buffer can hold. This

typically occurs when there are several fast machines on different

ports trying to access a machine across the switch. If this is

infrequent, you don’t need to do anything. However, if this occurs

often on the network, then the devices causing flow control to activate

should be identified and moved to the same segment as the device that

they are talking to.

When Ethernet bandwidth is temporarily insufficient for the traffic,

there are only three possible actions: drop packets, use flow control,

or segment the network. Buffering packets only works for a very short

while. An extended overload will eventually overflow buffers and

cause dropped packets. Flow control stops transmission on a port and

forces devices to resend packets, ensuring that packets aren’t lost.

This is the most reasonable solution, since it relies on Ethernet’s

inherent collision detection mechanism to relieve temporary overload.

Repeater count limitations

The switch doesn’t count as a repeater. Each port on the switch can

support a full Fast Ethernet network. There can be one repeater/hub

between the switch and any workstations or servers (a stack of Intel

Express 100BASE-TX Hubs counts as a single hub). Also, the total

diameter of a segment can’t exceed 200 meters when using UTP

cable. That is, the distance between any two nodes on a segment (or

the switch and a node on the other side of a hub) can’t exceed 200

meters.

Configuring and

Managing the Switch

You don’t need to read this chapter unless you want to change the

Express Switching Hub’s default configuration (see Appendix A for a

list of defaults) or intend to manage the switch. The switch is ready to

go simply by plugging it in and turning the power on.

However, if you need to change the default configuration or manage

the switch, there are two ways:

•

Use SNMP-compliant management software (not included).

However, you must first use the Console Manager to assign an IP

address to the switch.

•

Use the Express Switching Hub’s internal Console Manager.

Download from Www.Somanuals.com. All Manuals Search And Download.

C H A P T E R 2

Intel Express 100BASE-TX Switching Hub

Accessing the Console

Manager

The Console Manager software is contained in the switch’s

nonvolatile RAM (NVRAM); you don’t need to install any software.

To access the Console Manager:

Use the null-modem cable (included with the switch) to connect a

workstation’s COM port to the Console Mgmt port on the switch.

Console Mgmt

PC-3442

Open a terminal emulation program (such as Windows Terminal).

Select the COM port and these communication parameters:

9600 baud, eight data bits, no parity, one stop bit

In Windows Terminal, choose Communications from the Setting

menu.

Press E. The login prompt appears:

password:

By default, no login name or password is assigned. The password

you enter becomes active only after you reset the switch or turn

off the power. If you want the password to take effect

immediately, use the set-passwd command.

Accessing the Console Manager remotely

To access remotely through Telnet, you must first set the IP

configuration of the switch using the set-ip-conf command (see

page 32 for instructions). You can then use Telnet to reach the switch.

In a remote session, all commands work exactly as if a terminal were

directly connected to the Console Mgmt port. Note that only one

console session can be active at a time. After the first Telnet session is

established, the switch refuses other Telnet connections until the

current session is closed. To terminate an active Telnet session, press

E three times from the serial interface.

create VLANs.

Entering commands

To enter commands, type the command name followed by any

parameters and press E. For example, typing sys-stat E

at the command prompt displays basic system status information.

Items in angle brackets represent values. For example, <IPaddress>

represents an IP address in dotted decimal notation (such as

123.1.1.7).

Items in { } and separated by | represent alternatives for an

argument. For example,

get-comm {read|write|*}

means you can type one of the following

get-comm read

get-comm write

get-comm *

If you enter a command incorrectly, a message indicates the type of

error that occurred. For example, typing a nonexistent command gives

the following message:

SYS_console> pin

command <pin> not found

If the command exists but the number of parameters is incorrect, the

following message is displayed:

SYS_console> ping

Configuring and Managing the Switch

Console Manager command groups

The Console Manager has several categories of commands:

•

Console commands: help, banner, serial line setup, console

parameters setup.

System commands: system status, reset commands, download

commands, and system debug commands.

IP commands: IP address setup, parameter and information

display.

SNMP agent commands: SNMP settings, management, and trap

options.

Switching database commands: aging time management and

switching database entry management.

Spanning tree commands: disabling or manually configuring the

spanning tree protocol.

•

VLAN commands: management of security virtual LANs.

Port configuration commands: duplex and other port settings.

Switching statistics commands: traffic and packet counters.

The following sections explain some of the more commonly used

commands for configuring ports and monitoring traffic statistics.

Configuring a port for full duplex

Commands used

set-port-dplex Sets the duplex mode on the specified port.

get-port-cfg

Displays the current port configurations.

Configuring a port for full duplex allows the switch to send and

receive packets simultaneously with the destination device. To

establish a full-duplex link, both the switch and the destination device

must be configured for full duplex.

NOTE

Setting a port to full duplex

automatically disables flow

control. Since collisions don’t

happen on a full-duplex link,

flow control isn’t needed.

Additionally, the link must be to a switch, workstation, or server. You

cannot establish a full-duplex link to a device that broadcasts

incoming packets to every port on the device. This excludes most

shared hubs, repeaters, or concentrators.

C H A P T E R 2

Intel Express 100BASE-TX Switching Hub

NOTE

To configure a port for full duplex

You must have a point-to-

point connection to establish

a full-duplex connection

(shared hubs/repeaters/

concentrators aren’t capable

of full duplex). Additionally,

both points of the connection

must be configured for full

duplex.

Configure the adapter or switch port on the other end for full

duplex.

Set the Express Switching Hub port to full duplex. This example

sets port 3 to full duplex:

set-port-dplex 3 full

Check the FC/FD LED. It should be solid yellow, indicating full

duplex.

Configuring the SNMP agent for IP

Commands used

set-ip-conf

ping

Sets IP address, netmask, and broadcast address.

Contacts another IP device.

The switch can be monitored and controlled through any SNMP-

compliant network management system (NMS). First, you must

configure the SNMP agent by assigning an IP address.

To configure the SNMP agent

Set the IP configuration. Type the command:

set-ip-conf 192.1.1.64 255.255.255.0 192.1.1.255

If the switch doesn’t have an IP address, then the specified IP

configuration is changed immediately and saved in NVRAM.

If the switch is already configured, the command changes only the

NVRAM. To use the new parameters, reset the switch using the

warm-resetcommand.

Test the installation. Type the command:

SYS_console> ping 192.1.1.1 2

This example tests connectivity from the switch to a workstation

with an IP address of 192.1.1.1. For more information on the ping

command, see page 33.

Download the MIB from Intel’s Customer Support World Wide

Web site (http://www-cs.intel.com). The file is compressed in the

file SWCH1MIB.EXE.

C H A P T E R 2

Configuring and Managing the Switch

Monitoring traffic

Commands used

get-br-cnt

Displays the packet statistics for a port. For a

complete description, see page 52.

get-eth-cnt

Displays the Ethernet counters for a port.

get-colls-cnt

Displays the collision distribution counters for a

port.

get-rmon-cnt

get-sdist-cnt

Displays the Ethernet RMON counters for a port.

Displays the packet size distribution counters for a

port.

get-mgm-brcnt

clr-cnt

Displays the statistics for the management port.

Resets the Ethernet and bridging statistics.

Use monitoring commands to determine the traffic volume from

specific ports or between ports. This allows you to determine the

traffic patterns of your network and adjust your network topology for

maximum efficiency.

Statistics are generated for the current session. Reset counters by

using the clr-cnt command, resetting the switch, or cycling the

power.

In general, keep devices that primarily talk to each other on the same

segment (remember, each port is a Fast Ethernet segment). For

example, if a high volume of traffic is forwarded from port 4 to port

3, determine which devices are generating traffic and move them to

the same segment. This often happens when users are accessing a

server on a separate segment. A change may not be efficient,

however, if users from several segments all access the same server

frequently.

To check traffic on a port

Determine the port you want to check.

Type the command:

SYS_console> get-br-cnt 3

====================================================

In this example, a station on port 3 is accessing a server on port 4. To

reduce the amount of traffic crossing the switch, the server should be

connected to a hub on port 3 instead of a hub on port 4. This keeps

traffic localized to the same Fast Ethernet segment.

Creating VLANs

Commands used

set-vbc-domain Sets up a Virtual Broadcast Domain (VBD).

del-vbc-domain Deletes a VBD.

get-vbc-tbl

set-sec-vlan

del-sec-vlan

get-svlan-tbl

Displays the VBD table.

Sets up a security VLAN.

Deletes a security VLAN.

Displays the security VLAN table.

There are two types of VLANs:

•

Security VLANs (SVLANs). Ports in an SVLAN can exchange

packets only with other ports in the same SVLAN.

•

VBDs: Ports in a virtual broadcast domain can exchange packets

only with other ports in the same VBD. However, they can see

broadcast frames from other ports in the same VBD.

Use only one type. Configuring both types in the same switch can

lead to unpredictable traffic patterns.

If you want a device to talk to multiple VLANs (for example, a

management workstation), apply a custom filter to the device. See

page 24 for instructions.

C H A P T E R 2

Configuring and Managing the Switch

To create an SVLAN

Determine the ports you want to group together.

Type the command:

set-sec-vlan all 3-4-5

This command groups port 3, 4, and 5 as an SVLAN immediately

and saves the entry in NVRAM. Replace all with nvramto save

the entry without changing it immediately or with runto change

the entry now without saving it.

To display a summary of saved SVLANs, type

get-svlan-tbl nvram

Any SVLANs created with the nvramor alloption are

displayed.

To create a VBD

Determine the ports you want to group together.

Type the command:

set-vbc-domain run 3-5-6-7

This command groups port 3, 5, 6, and 7 as a VBD temporarily

(only until the next reset or power down). To save the entry and

have it take effect now, replace runwith all.

Configuring the spanning tree

Commands used

get-stp

set-stp

Displays the spanning tree session state.

Enables or disables the spanning tree for the next

session.

get-st-bcfg

get-st-pcfg

Displays the spanning tree bridge parameters.

Displays the spanning tree port parameters table.

get-st-syscfg Displays the spanning tree system ports

configuration.

set-br-prio

Sets the spanning tree bridge priority.

set-br-maxage Sets the spanning tree bridge maximum age.

set-br-hellot Sets the spanning tree bridge hello time.

set-br-fwdel

set-prt-prio

set-prt-enb

Sets the spanning tree bridge forward delay.

Sets the spanning tree port priority.

Enables or disables a port spanning tree.

set-prt-pcost Sets the spanning tree port path cost.

Spanning tree is a protocol that determines which port is turned off in

a redundant configuration. Spanning tree is enabled anytime a packet

could potentially be caught in an infinite loop on the network (for

example, when two switches are connected to each other and also to

the same bridge). The protocol uses the port with the lowest-cost path

and turns off the other port. If one path fails, the other path is

automatically turned on.

Spanning tree is enabled by default. See the “Spanning tree

commands” section later in this chapter for more information.

Creating custom filters

Commands used

add-cf-entry

del-cf-entry

get-lt-filter

get-nv-cftbl

Adds a custom filter entry.

Deletes a custom filter entry.

Displays the filter for a given MAC address.

Displays all configured custom filters.

Download from Www.Somanuals.com. All Manuals Search And Download.

C H A P T E R 2

Configuring and Managing the Switch

Use custom filters to control where the switch forwards packets from

a given MAC address. Custom filters override VLANs. This is useful

when you want a device to talk to devices outside of its VLAN.

Filters are defined for a set of ports. For example, you can set a

custom filter that tells the switch to forward packets received on ports

3 and 4 to ports 6 and 7.

To set a custom filter

Determine the MAC address of the device you’re applying the

filter to.

Determine the switch ports where the device’s packets will arrive.

These are the source ports.

NOTE

Source ports start with port 1.

Destination ports start with

port 0, which is the internal

SNMP management port.

Determine the switch ports where the device’s packets will be

forwarded. These are the destination ports.

Use the Custom Filter Port Tables in Appendix A to find the

source and destination port hexadecimal equivalents.

Type the command:

add-cf-entry perm 00-A0-C9-11-11-11 C C0

This custom filter would send packets from the device with MAC

address 00-A0-00-11-11-11 arriving on ports 3 or 4 (hexadecimal

C) to both ports 6 and 7 (hexadecimal C0).

the interface. SLIP can be used with a terminal server but not with a

modem. The SLIP interface can be configured using the

set-slip-conf console command. The serial port can be returned to

console mode by pressing E three consecutive times from a

terminal.

set-sw-file

set-sw-file <filename>

Sets the name of the file downloaded by TFTP (trivial file transfer

protocol). This command is used in case of an update to the switch’s

firmware. The file name must match the name of the agent software

file on a TFTP server. When TFTP is used, the per-packet

retransmission time-out value on the server (not the switch) must be

increased to 10 seconds, since the SNMP agent must first erase its

flash EEPROM, which takes about 30 seconds.

Ping commands

The ping command sends an Internet Control Message Protocol

(ICMP) echo request packet to a station. The ping process is

asynchronous, so any responses are mixed in with other system

console messages. For this reason, it’s best to avoid typing other

commands (except ping-stop, which cancels the ping) while the ping

process is active.

ping

C H A P T E R 2

Intel Express 100BASE-TX Switching Hub

Ping a device (at IP address) numberof times or 0for endless ping.

The ping process sends a numberof datagrams, one per second. One

line of output appears for every response received. Normal response

time is 1 to 10 seconds.

The ping command is intended for testing the connectivity between

the switch and an IP station. It is not intended as a traffic generator, so

it’s best to avoid using an endless ping. To stop the ping, use cC

or enter the ping-stop command.

SYS_console> ping 129.1.1.1 10

129.001.001.001 Alive. echo reply: id 297, seq 4, echo-data-len 8

PING process stopped - press <CR> for prompt

— press <CR> to get the prompt again

If the host doesn’t respond, the console prompt appears and no output

is added. Failure to get an echo response from a host may be due to

the following:

•

A bad physical connection.

A nonexistent or inactive host.

network unreachable: no corresponding entry in the routing table.

destination unreachable: the default gateway failed to route the

datagram.

•

outdated Address Resolution Protocol (ARP) table information:

clear the ARP table with the del-arp-entrycommand.

If there’s an active ping process due to a previous “long” ping

command and you try to start a new ping, the command fails.

ping-stop

Stops the active ping process. You can also use cC.

del-arp-entry

del-arp-entry {<IPaddress>|*}

Deletes entries from the ARP table. If you enter an IP address, the

matching ARP entry is deleted. If you enter *, the entire ARP table is

cleared. Use this command if the network topology has physically

changed. For example, if a management station moves from one

segment to another, its port number changes.

SNMP commands

This section lists commands for configuring the SNMP agent itself,

access and trap configuration.

SNMP community strings

SNMP community strings authenticate access to the Management

Information Base (MIB). Community strings function as “passwords”

embedded in every SNMP packet. The community string must match

one of the two community strings configured in the switch for the

message to be processed. There are two community strings, one for

each of the following type of access:

• read mode gives read access to all the objects in the MIB, but

doesn’t allow write access.

• write mode gives read and write access to all objects in the MIB.

get-comm

get-comm {read|write|*}

Displays the SNMP community string for a given access mode (read

or write). If the access mode is specified as *, both read and write

community strings are displayed.

SYS_console> get-comm *

Current read community is: < public >

Current write community is: < private >

Specifies the SNMP community string for each of the two access

modes (read and write).

SYS_console> set-comm write password

New write community is: < password >

SNMP trap message commands

When the switch detects an irregular event, it generates a trap. A trap

is a notification message that can be sent to predefined network

management stations. A trap event can be a cold or warm reset,

detection of a port link status change, an SNMP authentication failure

Switching database commands

This section contains instructions for managing the switching

database with the Console Manager.

The switching database, also called a learn table or address table,

consists of 1024 entries. Each active entry contains the information

relevant to a network node, identified by its Ethernet MAC address.

Each entry contains the following information:

Lock. If on (denoted as a +), the entry is a static entry and isn’t

deleted by the switch aging process. If off (denoted as a -), the entry is

a dynamic entry that’s automatically deleted if the workstation is not

active during the aging time period.

C H A P T E R 2

Intel Express 100BASE-TX Switching Hub

Self(not user configurable). If on (denoted as a +), the entry is a

system address. These are the switch’s individual and group

addresses, as well as other addresses added by the management

system. If off (denoted as a -), the entry contains the MAC address of

a station on the network.

Dport. The destination port where frames from the entry are

forwarded. If the MAC address is a custom filter, this doesn’t apply.

Mgmt. If on (denoted as a +), frames from the entry are sent to the

management port on the switch.

The first section, “Virtual addresses,” lists commands relevant to

standard MAC addresses (for example, determining the behavior of

the switch when it sees a particular address). The second section,

“Custom filtering,” lists commands pertinent to the custom filtering

capabilities of the switch.

the device is inactive for 300 seconds (the default aging time).

get-lt-age

Displays the switching database aging time in seconds. This is the

amount of time the switch stores a device’s MAC address before

clearing it from the database. An entry whose MAC address doesn’t

appear in the source field of an incoming packet for this period of

time is discarded. The default is 300 seconds.

Custom filtering

Custom filters are useful for ensuring that a device can reach other

devices regardless of where the device is attached. For example, if

you have a laptop computer that acts as a management station, you

want to make sure you can reach your servers from any part of your

network, even if some segments have security VLAN restrictions.

The custom filter entry for an address is shown onscreen as a matrix.

The source (SRC) column lists the available source ports (1 through 7,

where ports 1 and 2 may or may not be installed). The other columns

each represent an available destination port. A + represents a

forwarding path. In the example, each source port (except port 3,

because ports don’t forward frames to themselves) forwards frames to

port 3.

sport is a hexadecimal representation of incoming ports, and dport is

a hexadecimal bitmask of representation of outgoing ports. Because

bitmasks are difficult to determine, a list of numbers for every

combination of source and destination ports is listed in Appendix A.

Packets arriving at the switch with the destination MAC address from

any port specified in sport are transmitted to all ports specified in

dport.

Troubleshooting

If there is an operating problem with the Express Switching Hub,

incorrect configuration or cabling is probably the cause. Try the

troubleshooting steps below in order:

Verify that your cables are wired correctly. This is the most

common problem. Use a UTP crossover cable to directly connect

another switch, server, or workstation to the switch. Use a straight-

through cables when connecting to a repeater. See page 8 for more

information.

Make sure the unit is plugged into a grounded, functioning AC

outlet providing between 90 VAC and 264 VAC at 50/60 Hz.

Review the Link LEDs of other devices to ensure that those ports

you believe should be functioning are properly attached to the

switch with a Category 5 UTP cable.

Review the switch’s Link LEDS to ensure that ports you believe

should be functioning are properly configured, and not disabled or

partitioned.

If you configured a port for full duplex, make sure the device on

the other end is configured for full duplex and is capable of

transmitting in full duplex. Remember, you must have a point-to-

point connection for a full-duplex link. Most repeaters aren’t

capable of full duplex.

C H A P T E R 3

Intel Express 100BASE-TX Switching Hub

If the FC/FD LED shows excessive activity, see Chapter 1 for

recommendations on dealing with excessive flow control.

Make sure that the equipment attached to the switch is properly

configured. If the CLSN LED is on continuously, you may have a

problem with an adapter on the segment.

Use the Console Manager to check the switch’s status. Use the

sys-statcommand to check the overall system status and the get-

port-cfgcommand to check the status of each port.

If you encounter any situations or problems you cannot solve, get the

following information:

•

The serial number of the Express Switching Hub printed on the

back side of the switch.

•

The firmware revision number displayed in the Console Manager

sys-statmessage.

•

The configuration of the equipment connected to the switch.

The sequence of events leading up to your problem.

Actions you have already taken.

Technical Information

SNMP and MIB Support

The Express Switching Hub contains a built-in SNMP agent running

on the SNMP processor board. This allows each Express Switching

Hub to be managed from a centralized management station via any

SNMP-compliant NMS.

The SNMP agent software complies with the following standards:

•

RFC 1155, The Structure of Management Information (SMI) for

TCP/IP Based Internets, 5/90.

RFC 1556, Management Information Base (MIB) for Network

Managers of TCP/IP Based Internets, 5/90.

RFC 1557, The Simple Network Management Protocol (SNMP), 5/

90.

•

RFC 1213, The Management Information Base II (MIB II), 3/91.

RFC 1643, Definitions of Managed Objects for the Ethernet-like

Interface Types.

•

RFC 1573, Evolution of the Interfaces Group of MIB-II, 1/94.

RFC 1493, Definitions of Managed Objects for Bridges, 7/93.

RFC 793, Transmission Control Protocol.

RFC 854, Telnet Protocol Specification.

RFC 1055, Nonstandard for transmission of IP datagrams over

serial lines: SLIP, 1/88.

The SNMP agent uses UDP/IP (RFC 768, RFC 950, RFC 1071 and

RFC 791) as OSI layers 3 and 4 protocols, and ICMP (RFC 792) and

ARP (RFC 826) to complete the UDP/IP protocol suite.

The UDP/IP stack implementation is conformant to:

•

RFC 1122, Requirements for Internet hosts, communication layers.

RFC 1123, Requirements for Internet hosts, application and

support.

The Express Switching Hub may be managed by any SNMP Manager

that conforms to the above standards.

The Express Switching Hub implements an Intel Enterprise MIB.
