* Note: If you have ATM Uplink Modules in the chassis and you
set the Age Timer value to less than 30 seconds, you
must change the Flush MAC Timer on each ATM
Uplink module to be less than or equal to the new Age
Timer value.
Enter a new value in the Super Age Time field. The valid entries
are 1-30 days. The Super Age Timer marks all invalid table entries,
then checks to see if they remain invalid for the specified super age
interval. This clears the table of entries that are no longer used. The
default value is 7 days.
Click APPLY to save your changes, or CANCEL to restore previous
settings.
