SET SWITCH AGINGTIMER|AGEINGTIMER
Syntax
set switch agingtimer|ageingtimer= value
Parameter
agingtimer or 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 stack uses the aging timer to delete inactive dynamic MAC addresses
from the MAC address table in the master switch. When the stack 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, it deletes
the address from the table. 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addresses of nodes that are no longer active.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. No dynamic MAC
addresses are aged out and the table stops learning new addresses after
reaching its maximum capacity.
To view the current setting for the MAC address aging timer, refer to
“SHOW SWITCH AGINGTIMER|AGEINGTIMER” on page 136.
Example
The following command sets the aging timer to 120 seconds (2 minutes):
set switch agingtimer=120
