Intelligent Switching software version 8.1.1 supports the
CoreBuilder 2500 ATM Module, which provides a single OC-3 155 Mbps
interface (multimode fiber) into a high-speed slot.
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.
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
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.
The parameter broadcast address in the IP interface definition
procedures has been changed to advertisement address(es),
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
