Bridging Commands
The Bridge Management menu provides several commands that are useful in pinpointing
problems in the network. The commands allow you to lookup specific MAC addresses and
where they were learned, create and view static bridge addresses, view information on
remote trunking stations, view MAC address statistics for a group or a port, or look up infor-
mation on domain mappings. Many times a network problem can be tracked down by view-
