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.
