SET SWITCH AGINGTIMER|AGEINGTIMER
Syntax
set switch agingtimer|ageingtimer= value
Parameter
agingtimer Specifies the aging timer for the MAC address table.
ageingtimer The value is in seconds. The range is 0 to 1048575.
The default is 300 seconds (5 minutes). The
parameters are equivalent.
Description
The switch uses the aging timer to delete inactive dynamic MAC
addresses from the MAC address table. When the switch detects that no
packets have been sent to or received from a particular MAC address in
the table after the period specified by the aging time, the switch deletes
the address. This prevents the table from becoming full of addresses of
nodes that are no longer active. Setting the aging timer to 0 disables the
timer and therefore no dynamic MAC addresses are aged out.
To view the current setting for the MAC address aging timer, refer to
“SHOW SWITCH AGINGTIMER|AGEINGTIMER” on page 483.
Example
The following command sets the aging timer to 120 seconds (2 minutes):
set switch agingtimer=120
