FDB Commands
Egress flooding can be disabled on ports that are in a load-sharing group. If that is the situation, the
●
ports in the group take on the egress flooding state of the master port; each member port of the load-
sharing group has the same state as the master port.
FDB learning is independent of egress flooding; either can be enabled or disabled independently.
●
Disabling unicast (or all) egress flooding to a port also stops packets with unknown MAC addresses
●
to be flooded to that port.
Disabling broadcast (or all) egress flooding to a port also stops broadcast packets to be flooded to
●
that port.
BlackDiamond 8800 family of switches (formerly known as Aspen) and Summit X450 switch only. You can
enable egress flooding for unicast, multicast, or broadcast MAC addresses, as well as for all packets on
the ports of the BlackDiamond 8800 family of switches or the Summit X450 switch.
BlackDiamond 10K switch only. You must enable egress flooding on all packets on the specified port or
ports. You cannot specify broadcast, unicast, or multicast packets; the egress flooding command applies
to all packets.
Example
The following command enables egress flooding on slot 1, ports 1 and 2 on a BlackDiamond 10K
switch:
enable flooding all_cast port 1:1-1:2
The following command enables unicast flooding on ports 13-17 on a Summit X450 switch:
enable flooding unicast port 13-17
