Usage Guidelines
If hosts do not send continuously, increase the aging time to record the dynamic entries for a longer time.
Increasing the time can reduce the possibility of flooding when the hosts send again.
If you do not specify a specific VLAN, this command sets the aging time for all VLANs and bridge
domains.
You can verify your setting by entering the show mac address-table aging-time privileged EXEC
command.
Examples This example shows how to set the aging time to 200 seconds for all VLANs and bridge domains:
Switch(config)# mac address-table aging-time 200
OL-28238-01
mac address-table aging-time {0 | 10-1000000}[bridge-domain domain-id | routed-mac | vlan
vlan-id]
no mac address-table aging-time {0 | 10-1000000} [bridge-domain vlan-id | routed-mac | vlan
vlan-id]
This value disables aging. Static address entries are never aged or removed from
the table.
Aging time in seconds. The range is 10 to 1000000 seconds.
(Optional) Specifies a bridge domain to which to apply the aging time. The bridge
domain ID range is from 1 to 8000.
(Optional) Specifies applying the aging time to routed MAC addresses.
