COREBUILDER 2500 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.
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. Table 1 Patch Descriptions Patch No. 5 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 save process and .nvd file extensions.
About Software Version 8.1.2 9 Table 1 Patch Descriptions (continued) Patch No. 25 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.
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.
System Issues Upgrade Considerations Restrictions with ATM and 10BASE-FL Modules 11 There are three primary 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 display at the top level of the Administration Console.
COREBUILDER 2500 INTELLIGENT SWITCHING SOFTWARE VERSION 8.1.2 Table 2 outlines the configuration restrictions.

APPENDIX A: NEW FEATURES IN INTELLIGENT SWITCHING SOFTWARE VERSION 8.1.
B ADMINISTERING ATM This appendix describes how to administer asynchronous transfer mode (ATM) on a LANplex® 2500 or CoreBuilder® 2500 system. It covers the following topics: ■ ATM in Your Network ■ Before You Configure ATM ■ LAN Emulation ■ Administering UNI Management Entities ■ Administering ATM Ports Before you add an ATM module to your system, see “Restrictions with ATM and 10BASE-FL Modules” on page 11 for details.
APPENDIX B: ADMINISTERING ATM ATM in Your Network LAN Emulation and Classical IP 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.
Before You Configure ATM Before You Configure ATM Checking ATM Link Status 37 Before you configure ATM, follow these steps: ■ Check the ATM link status. ■ Verify that address registration is operational. ■ Verify that signalling is operational. To check the link status, follow these steps: 1 From the top level of the Administration Console, enter: atm ume display You are prompted for the number(s) of the UME that you want to display. 2 Enter the number(s) of the UME(s) or all.
APPENDIX B: ADMINISTERING ATM Verifying Address Registration After you ensure that the link is connected, verify that the system is able to register addresses at both the network and the user sides of the UME Network Interface (UNI). Two addresses — one for LAN Emulation and one for Classical IP over ATM — are registered at the network side.
Before You Configure ATM Verifying Signaling 39 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.
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: ■ A Broadcast and Unknown Server (BUS) — Responsible for handling broadcast, multicast, and initial unicast frames sent from a LAN Emulation Client. Each ELAN contains only one BUS.
LAN Emulation Eliminating Bridge Loops in ELAN Configurations 41 When configuring more than one LEC in a LANplex 2500 or 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).
APPENDIX B: ADMINISTERING ATM 3 Enter the LECS access type. Choices are lecs and manual. If you choose LECS as your means of joining an ELAN, and another CoreBuilder system provides LES and BUS services, you must update the directly attached ATM switch LECS with the ELAN name and the corresponding LES address. 4 Enter the name of the emulated LAN to which you are adding the client, or press Return to choose the default ELAN shown in brackets. The ELAN name may contain a maximum of 32 characters.
LAN Emulation Administering LAN Emulation Clients 43 From the Administration Console you can: ■ Display summary or detailed information about emulated LAN clients ■ Modify information for emulated LAN clients ■ Define a client for inclusion in an emulated LAN ■ Remove a client from the network Displaying Information About LAN Emulation Clients You can display a summary report or a detailed report of information about LAN Emulation Clients.

APPENDIX B: ADMINISTERING ATM Modifying Information About LAN Emulation Clients To modify LAN Emulation Client parameters, follow these steps: 1 From the top level of the Administration Console, enter: atm lane modify You are prompted for the parameter that you want to modify. 2 Enter the parameter. You are prompted for the number(s) of the LEC(s) that you want to modify. 3 Select the number(s) of the LEC(s) or all. You are prompted for the new value of the option that you selected.
Administering UNI Management Entities Administering UNI Management Entities 49 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.
APPENDIX B: ADMINISTERING ATM Table 7 describes the fields provided in the UNI Management Entity displays.
Administering UNI Management Entities Listing Network Prefixes and Addresses 51 You can list the registered network prefixes and addresses of any ATM port. To list prefixes and addresses: 1 From the top level of the Administration Console, enter: atm ume list You are prompted for an ATM port. 2 Select an ATM port. The registered network prefixes and addresses are listed for the port that you requested.
APPENDIX B: ADMINISTERING ATM Setting the Virtual Path Identifier For each ATM port, you can set the virtual path identifier (VPI) used by UME for the Interim Local Management Interface (ILMI). To set the VPI: 1 From the top level of the Administration Console, enter: atm ume vpi You are prompted for an ATM port. 2 Enter the ATM port for which you want to set the virtual path identifier. 3 Enter the new value for the VPI. The new VPI takes effect after the port has been disabled and then enabled.
Administering ATM Ports Administering ATM Ports Displaying Port Information 53 You can display summary or detailed reports, create labels, and list virtual channel connection (VCC) information for ATM ports. You can display a summary of ATM port information or a detailed report.
