System Issues

25

If you attempt to run CoreBuilder 6000 system software revision 8.2.3 on an LMM+ at revision 2.11 or earlier, the system fails to reboot when you turn it on. See “Hardware Dependencies” on page 1.

You can configure a maximum total of 100 routing interfaces for all switching modules in a single CoreBuilder 6000 system.

When your system is connected to the MBONE (the Internet’s multicast backbone) and multicast routing is enabled, configure a maximum of 3 slots for multicast routing.

When you use the Administration Console to display all instances of a given MAC address in a mixed token ring and Ethernet environment, use the find command for both the noncanonical and canonical formats.

ESMs do not support IGMP snooping. To avoid unwanted traffic, filter IP multicast traffic with a packet filter.

The Ethernet Switching Module (ESM) and the Token Ring Switching Module (TRSM) incorrectly report transmit filter statistics.

The ESM and TRSM FDDI packet filters cannot access packet data beyond byte 16 in a packet.

VLAN statistics are not supported on the ESM.
