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.
Examples This example shows how to set the aging time to 200 seconds for all VLANs:
Switch(config)# mac address-table aging-time 200
You can verify your setting by entering the show mac address-table aging-time privileged EXEC
command.
