INTELLIGENT SWITCHING

SOFTWARE VERSION 8.1.2

Overview

These release notes describe CoreBuilder^®2500 Intelligent Switching

software, version 8.1.2, from 3Com Corporation, dated February 19,

1999. This release supersedes LANplex^®2500 Intelligent Switching

software, version 8.1.1, dated December 20, 1996.

In mid-1997, 3Com changed the name of the LANplex 2500 switch to

the CoreBuilder 2500 switch. In version 8.1.2, however, the LANplex

name and related abbreviations, such as lpand lpx, remain in the

filenames and displays on the Administration Console.

These release notes use the CoreBuilder name. If applicable for your

system, substitute LANplex for CoreBuilder throughout these release

notes.

Before You Start Before you install Intelligent Switching software version 8.1.2 on your

system, be sure to read this document in its entirety so that you

understand the release features, system issues, known problems,

supported configurations, and the software installation procedure.

Upgrade You can load Intelligent Switching software version 8.1.2 on any

Considerations LANplex 2500 or CoreBuilder 2500 system. Before you upgrade a system,

read “Upgrade Considerations” on page 11 for important information

and cautions.

COREBUILDER 2500 INTELLIGENT SWITCHING SOFTWARE VERSION 8.1.2

About Software

Version 8.1.2

Intelligent Switching software version 8.1.2 is a maintenance release that

includes several patches (bug fixes). Table 1 lists the patch numbers and

descriptions.

Patch Descriptions

Table 1

Patch

No.

Descriptions of Fixed Problems

Added the ability to save nonvolatile configuration data from one system

and restore it to another system.

Fixed a problem with the nvdata saveprocess and .nvd file extensions.

Fixed a buffer leak problem with IPX NetBIOS in configurations that have

no outgoing interfaces.

Fixed a problem in which IPX NetBIOS network numbers were corrupted

when using FDDI 802.2 encapsulation on an IPX interface. This problem

affected the processing of an IPX NetBIOS frame and potentially caused it

to be dropped.

Fixed a problem with Fast Ethernet port lockups.

Fixed the FDDI Source Route frame problem with Panic 3 errors. Errors

were caused by frames with unicast DA, known DA, source route SA,

known SA, and frames in error.

Fixed a problem with multibuffer FDDI and ATM Panic 3 errors.

Fixed an error with the max VLAN condition that occurred while adding

VLANs.

Fixed the corruption problem with frames that required fragmentation

between FDDI and Ethernet.

Fixed filtering problems with ATM LECs.

Fixed a problem in which, if an IP VLAN was removed, then the remaining

IP VLANs could no longer communicate with each other through the

system.

Fixed a problem in which AUI and BNC ports hung when a certain amount

of collision activity occurred.

Revised the fix that dealt with frame corruption during FDDI-to-Fast

Ethernet or FDDI-to-Ethernet fragmentation.

Fixed a problem with the initialization and timing of ATM LECs.

Fixed a problem that occurred if an ATM multicast limit was set. If that limit

value was reached on an ATM interface, all future traffic through that

interface was dropped.

Fixed the Panic78 frame buffer overreturn problem that was caused by

Source Route frames in error. This fix is only for Transparent Bridge Mode.

About Software Version 8.1.2

Patch Descriptions (continued)

Table 1

Patch

No.

Descriptions of Fixed Problems

Added functionality to disable ATM throttling to the Broadcast and

Unknown Server (BUS). A value indicates the number of unknown

addresses that can be sent to the BUS. A new value of "0" disables this

function.

Fixed a problem with console lockup that can occur after you enter a

Ctrl+C command at the Administration Console.

Fixed performance problems (slow responses, lost connections, and so on)

that occurred when the system accessed the ARP table via SNMP.

Fixed a memory leak that was caused by ARP frames.

Fixed an ARP-related problem that resulted in buffer loss.

Added support for LEC IDs of zero.

Fixed the cause of various cp panic messages when the system is

interoperating in an ATM environment.

Fixed a buffer leak that was caused by receiving packets that were larger

than legal Ethernet sizes.

Changed how passwords are handled in the system.

Changed the system response for certain MIB requests. When the MIB

objects swSysSystemConsoleWritePwd and

swSysSystemConsoleAdminPwdare requested by a management

entity, the system now returns the message NoSuchName, regardless of

the access level of the community string that you use to request these

objects.

Fixed a problem with Rlogin so that customers can use Rlogin instead of

Telnet. The use of Telnet causes small memory leaks of about 40 bytes per

session. If you Telnet to a system with a Rev 7 motherboard every 15

minutes on a 7x24 basis, then it would take approximately 24 days to start

receiving memPartAllocerror messages when you access the system for

information. This time would be longer than 24 days for systems with Rev

8 motherboards and shorter for systems with Rev 6 motherboards,

because they have different amounts of memory. A system reboot or

power cycle returns all memory that is lost through the leaking process.

Provided a software fix for a flash memory issue. In certain circumstances,

if the system was rebooted, the system indicated unrecoverable checksum

errors. This fix incorporates a new expander file to be used during the

software installation process.

COREBUILDER 2500 INTELLIGENT SWITCHING SOFTWARE VERSION 8.1.2

System Issues

The following system issues have been identified for software

version 8.1.2:

■

When a ping is initiated from the CoreBuilder 2500 system and is

destined to an ATM device that has a specific ATM adapter card,

multiple pings are required before communication is initiated. This

situation arises because of the amount of time required for the

adapter card to resolve ATM ARP.

■

An ATM LEC cannot be configured as the backbone port in Express

Switching mode.

After you set a system baseline, ATM LEC bridge statistics are

incorrect.

■

You cannot set the ipDefaultTTLMIB variable.

When the ILMI autoconfiguration option is enabled on a

CoreBuilder 7000 switch, it could take several minutes for a LEC

configured on a CoreBuilder 2500 to join an emulated LAN.

■

Packet filters can access data only through byte 64 in the packet.

Roving Analysis frames that are sent over a remote Fast Ethernet

connection are truncated if greater than 1495 bytes.

■

Roving analysis is not supported on a system that has an ATM module

installed in the chassis.

Remote roving analysis is not supported over a Fast Ethernet

connection that has the Spanning Tree Protocol enabled.

Before you enable Express Switching mode, disable the backbone

port. Then, after you enable Express Switching mode, reenable the

backbone port.

■

The system cannot route FDDI multicast frames that are larger than

1500 bytes (that is, frames that require fragmentation).

The FCS error statistics field reports inaccurate values for Fast Ethernet

ports.

System Issues

There are three primary upgrade considerations:

Upgrade

Considerations

■

Once you install software version 7.0.0 or higher in a system that uses

a revision 8.0 motherboard, you can never install software versions

previous to version 7.0.0 in the future. To see if you have a revision 8.0

motherboard in your system, enter system displayat the top level

of the Administration Console. The first line of the display shows the

product name and, in parentheses, the revision number of the

motherboard.

■

If you are upgrading from a release prior to version 7.0.0, be aware

that the menu item ip forwardingwas changed to ip routing

at version 7.0.0. If you have created automated scripts that include

ip forwarding, edit them to reflect this command change.

If you are upgrading from a release prior to version 8.1.1,

be aware that the parameter broadcast addressin the IP

interface definition procedure was changed to

advertisement address(es)at version 8.1.1. If you have

created automated scripts that include broadcast address, edit

them to reflect this command change.

Each CoreBuilder 2500 chassis features two slots for low-speed modules

(Ethernet) and two slots for high-speed modules (ATM, FDDI, or Fast

Ethernet). At this release, however, the system supports only one ATM

module per chassis.

Restrictions with

ATM and 10BASE-FL

Modules

In addition, restrictions apply to certain configurations that mix one ATM

module with two older Ethernet 10BASE-FL modules (3C201400; no

longer orderable). The combination of these three modules causes certain

systems to draw excessive power and eventually fail. Whether your

system could be affected by this module-combination problem depends

on the revision level of the system motherboard.

You can order a newer version of the 10BASE-FL module (3C201400A).

The configuration restrictions described in this section do not apply to this

newer version of the 10BASE-FL module.

To determine the revision level of your system motherboard, enter

system displayat the top level of the Administration Console. The

first line of the display shows the product name and, in parentheses, the

revision number of the motherboard.

Software Installation To install CoreBuilder 2500 Intelligent Switching software version 8.1.2,

Process Summary follow these general steps, which are explained in greater detail in the

indicated sections:

1 Copy the software files from the Software CD-ROM or download the

software files from the 3Com Web Site to the hard disk of a host device.

See “Copying Software to a Hard Disk” for detailed instructions.

2 Prepare the system and the host device.

See “Preinstallation Tasks” for detailed instructions.

3 Install the diagnostic software file and system software files onto the

CoreBuilder 2500 system by retrieving the files from the host device.

See “Installing the Diagnostic Software” and “Installing the

System Software” for detailed instructions.

You can update software on the system while it is operating in a network.

The system continues to forward traffic during the installation, except

when the system is rebooting.

Copying Software Because you cannot directly load Intelligent Switching software

to a Hard Disk version 8.1.2 from the Software CD-ROM or the 3Com Web site onto

your system, you use an interim host device to transfer software files to

your system.

Prerequisites for the host device:

■

Must be able to function as an FTP server

■

Must use a UNIX, Windows 95, or Windows NT operating system

To copy the software to a host device, follow these steps:

1 Either:

a Copy the software files from the Intelligent Switching version 8.1.2

Software CD-ROM to the hard disk of the selected host device.

a Download the compressed file from the 3Com Web Site to the hard

disk of the selected host device. Begin with the following URL:

http://support.3com.com/software/switches.htm

b Decompress the file on the host device to reveal the individual

software files.

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

Software Installation Procedure

Because you need it later in the procedure, write down the exact

pathname, using exact letter case, for the location of each software file

on the host device.

If you copy files from one host device to another host device using the file

transfer protocol (FTP), be aware that the case of the letters in the

software filenames may change during the transfer.

Proceed to “Preinstallation Tasks” next.

To ensure that the system and the host device are ready to continue with

the procedure, follow these steps:

Preinstallation Tasks

Using the ip pingcommand, verify that the CoreBuilder 2500 system

can reach the host computer to which you copied the updated software.

See the CoreBuilder 2500 Administration Console User Guide for more

information about the ip pingcommand.

Verify that the host device has FTP server software running on it.

Using the system nvData savecommand, save your system’s

NVRAM configuration data.

See the CoreBuilder 2500 Administration Console User Guide for more

information about the system nvData savecommand.

APPENDIX A: NEW FEATURES IN INTELLIGENT SWITCHING SOFTWARE VERSION 8.1.1

Support for the Intelligent Switching software version 8.1.1 supports the

ATM Module CoreBuilder 2500 ATM Module, which provides a single OC-3 155 Mbps

interface (multimode fiber) into a high-speed slot.

Physical Configuration

Each CoreBuilder 2500 chassis has two slots for high-speed modules

(100 Mbps or higher) and two slots for low-speed modules. You can

install only one ATM module per chassis. See “Restrictions with ATM and

10BASE-FL Modules” on page 11 for details.

Features

The CoreBuilder 2500 ATM Module is designed to be fully interoperable

with other 3Com ATM switches, as well as with other switches that

comply with industry standards (UNI 3.0 and LANE 1.0).

The ATM module supports these features:

■

UNI 3.0 signaling

Procedure primarily to support nonbroadcast networks, such as ATM.

Previously, a broadcast address was configured for each IP interface. The

router used this IP address as the destination address for advertisements,

such as RIP updates. You may now enter one or more addresses, and the

router sends advertisements to each of these addresses. There is no

restriction on the addresses. They may be broadcast addresses, individual

addresses, or any combination. Separate multiple addresses with

commas (,).

State, has been added to the interface display table,

Field Added to the A new field,

Interface Display allowing you to view the state of all interfaces configured for each

switching module in the system.

The interface state is determined based on the state of all ports

associated with the interface. For IP, the state displayed is either Up

or Down:

■

The interface state is displayed as Downif no port in the defined

interface, including those in overlapping subnetworks, has established

link status. Link status is not established for FDDI DAS ports when

neither the A nor the B port has established link status.

■

The interface state is displayed as Upif one or more ports in the

defined interface, including those in overlapping subnetworks, have

established link status.

As the interface state changes, transitions are reflected in the

corresponding tables for all directly connected and associated routes.

For IP transitions, all routes that are associated with the interface time out

in the same manner as do learned routes that are not updated.

If link status is transitioned, previously defined configurations, such as

static routes, do not have to be redefined.

New System A menu option was added so that you can display the time — in minutes,

Uptime Menu hours, and days — since the last system reboot occurred.

APPENDIX B: ADMINISTERING ATM

ATM in Your

Network

ATM architecture differs fundamentally from IEEE 802.x technology. IEEE

802.x LANs, which are limited to FDDI, Ethernet, and token ring, are

connectionless and use the Media Access Control (MAC) addresses in

each packet to communicate to end-stations. ATM is connection-oriented

and uses an circuit identifier, called a virtual channel identifier, to

exchange data between two ATM stations over previously established

virtual channel connection (VCC).

LAN Emulation To forward data over an ATM interface in an existing network, two

and Classical IP methods are provided to adapt existing network layer protocols to the

connection-oriented paradigm of ATM:

■

— Supports transparent translation of higher

LAN Emulation (LANE)

level protocols, such as IP, IPX, and AppleTalk protocols. LANE also

supports broadcast and multicast addressing.

■

— Supports transparent translation of IP only

over ATM, and does not support broadcast or multicast addressing.

Classical IP is supported only in CoreBuilder 2500 Extended Switching

Software, version 8.1.0 or later. Thus, it does not apply to Intelligent

Switching Software version 8.1.2.

Before You Configure ATM

The ATM signaling protocol allows end-stations to establish, maintain,

and clear ATM connections between end points with virtual connections

(VCCs). Multiple virtual connections can exist on a physical link. There are

two types of virtual connections: a virtual path and a virtual channel.

Verifying Signaling

You can verify that signaling is operational by viewing the virtual

connections — virtual path identifiers (VPIs) and virtual channel identifiers

(VCIs) that the system has established.

To verify that signaling is operational, from the top level of the

Administration Console, enter atm ports vcc list

APPENDIX B: ADMINISTERING ATM

LAN Emulation

LAN Emulation (LANE) provides unicast, multicast, and broadcast network

behavior over connection-oriented ATM. An emulated LAN (ELAN) can

consist of many LAN emulation clients (LECs). An ELAN consists of the

following components:

■

— Responsible for

handling broadcast, multicast, and initial unicast frames sent from a

LAN Emulation Client. Each ELAN contains only one BUS.

A Broadcast and Unknown Server (BUS)

A LAN Emulation Server (LES)

— Responsible for registering and

resolving MAC addresses to ATM addresses for LECs. Each ELAN

contains only one LES.

LAN Emulation Clients (LECs)

— The end node from the perspective

of the ATM network. It performs data forwarding, address resolution,

and other control functions. Additionally, it maintains the LAN

emulation software.

■

— The LECS

A LAN Emulation Configuration Server (LECS)

provides configuration information about the ATM and LAN networks.

It also provides the address of the LES to the LEC.

Important considerations:

■

You must define a LES and a BUS as part of an ELAN before you can

define a LEC.

■

You can configure the LES and the BUS on the same LEC or on

different LECs.

Creating an You can create an 802.3 emulated LAN on ATM by defining the LAN’s

Emulated LAN servers (the BUS and the LES) and then configuring each LAN Emulation

Client (LEC).

To create an emulated LAN, follow these steps:

1 Determine the location of the BUS and LES.

You can define the BUS and LES in any LEC on the network, or on an

ATM switch, such as the 3Com CoreBuilder 7000 system.

2 Define the Broadcast and Unknown Server (BUS).

3 Define the LAN Emulation Server (LES).

4 Define the LAN Emulation Clients (LEC).

LAN Emulation

When configuring more than one LEC in a LANplex 2500 or

Eliminating Bridge

Loops in ELAN

CoreBuilder 2500 system, a bridge loop may be created. This possibility

exists because the LANplex can bridge between all ports, including logical

bridge ports (LECs). Because the Spanning Tree Protocol (STP) is off by

default, we recommend following this procedure when you create

multiple LECs with Intelligent Switching software:

Configurations

After you define all LECs, at the Enable Stateprompt, enter enable

Enable STP. From the top level of the Administration Console, enter:

bridge stpState enabled

Reboot the system.

The system adds the LECs to the bridge table.

You can configure a LAN Emulation Client (LEC) to join an existing 802.3

emulated LAN by providing information about the LAN Emulation Server

(LES) and the Broadcast and Unknown Server (BUS).

Configuring Clients to

Join an Existing

Emulated LAN

Defining LAN Emulation Clients

When you define a LAN Emulation Client, you give information necessary

for a client to be included in the emulated LAN. A BUS and a LES must

already be defined as part of the emulated LAN before you can define a

client.

When the client attempts to join the emulated LAN, some of the

configured information is carried along with the join request sent to the

LES. The LES can alter this information. The client then has the option of

accepting or rejecting any changes made by the LES. If the changes are

accepted or if there are no changes, the client successfully joins the

emulated LAN. Otherwise, the join fails.

To define a client:

From the top level of the Administration Console, enter:

atm lane define

Enter the number of the ATM port to which the client is attached.

You can attach only one client per port to the same emulated LAN.

Administering UNI Management Entities

Administering UNI

Management

Entities

A User-to-Network Interface (UNI) Management Entity (UME) implements

the management interface to the ATM network. Each ATM port has one

UME, which manages the network prefix and address tables and provides

access to the Interim Local Management Interface (ILMI) MIB.

Each CoreBuilder 2500 UME registers one address for LAN Emulation and

one address for Classical IP over ATM with the switch port to which it is

attached.

You can display information about each UME and configure its attributes.

When you display UME information for an ATM port, you display values

for the connection state, the VPI (virtual path identifier), the VCI (virtual

channel identifier), and other attributes.

Displaying UME
