Filtering Database 3-27
9E312/9E423 Module Bridging
The Port Source Addresses window displays the MAC addresses of all devices
that have transmitted packets that have been forwarded through the selected
bridging interface during the last cycle of the Filtering Database’s defined ageing
timer (learned addresses that have not transmitted a packet during one complete
cycle of the ageing timer are purged from the Source Address Table). For more
information on the Filtering Database, see Filtering Database on page 3-19.

Ageing Time window.

2. Type in the new Ageing Time (allowable range is 10 to 1,000,000 seconds; the
default is 300 seconds).
3. Click to accept the new Ageing Time, or click to exit the
window without making changes.
TIP
You can also open the Port Source Addresses window from the Module View by clicking
on the front panel interface of interest and selecting the Source Addressing option from the
menu that appears.
NOTE
The ageing time displayed in the Port Source Addresses window is the same as the ageing
time displayed in the Filtering Database window. The ageing time can be set from either
window, and any changes to its value will be reflected in both locations.
