Changing the Filtering Database Dynamic Ageing Time

The Dynamic Ageing Time determines how long an entry remains in the Filtering Database before being purged due to inactivity. Purging older entries ensures that the Filtering Database is always using current information to make filter/forward decisions.

To change the Dynamic Ageing Time:

1.In the Filtering Database window, click mouse button 1 on the Change Ageing Time button to open the Change Ageing Time window.

As you change the ageing time, SPMA converts seconds to days:hours:minutes:seconds.
