System Issues

■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.
