show fdb agingtime
Displays the aging timeout period for forwarding database entries.
Syntax show fdb agingtime [vlan vlan-id]
Defaults None.

Examples The following command displays the aging timeout period for all VLANs:
WSS# show fdb agingtime

command lists the aging timeout period for each VLAN separately.
