30APPENDIX 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

■LAN Emulation 1.0 (LEC support) — 2 Emulated LANs

■Dynamic configuration of Emulated LANs (ELANs)

■A maximum of 128 Virtual Connections (VCs) per system

■Management:

■UME Address registration

■MIBs: ILMI, AToM, LEC, SONET

For detailed information about administering the ATM module and related software commands, see Appendix B in these release notes.

Parameter Change in The parameter broadcast address in the IP interface definition Interface Definition procedures has been changed to advertisement address(es),

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 (,).
