MAC Address Table Management Commands 167
undo mac-address timer aging
View
System view
Parameter
aging age: Specifies the aging time (measured in seconds) of the Layer-2 dynamic
address table entry, ranging from 10 to 630. By default, the aging time is 300
seconds.
no-aging : No aging time.
Description
Use the mac-address timer command to configure the aging time of the Layer-2
dynamic address table entry.
Use the undo mac-address timer command to restore the default value.
If aging time is too short, the MAC address might be deleted before the switch
gets the address information. That way the switch broadcasts the received packets
to all the ports within the VLAN. This will affect the switch operation performance.
If aging time is too long, the switch will store a great number of out-of-date MAC
address tables. This will consume MAC address table resources and the switch will
not be able to update MAC address table according to the network change.
c
CAUTION: The aging of dynamic MAC address is completed during the second
aging cycle that has been configured.
Example
# Configure the entry aging time of Layer-2 dynamic address table to be 500
seconds.
