Bridging

Figure 2-18. Port Source Addresses Window

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 DatabaseÕs deÞned aging timer (learned addresses that have not transmitted a packet during one complete cycle of the aging timer are purged from the Source Address Table). For more information, see Filtering Database, page 2-41 .

NOTE

The aging time displayed in the Port Source Addresses window is the same as the aging time displayed in the Filtering Database window. The aging time can be set from either window, and any changes to its value will be reßected in both locations.

Setting the Aging Time

The Filtering Database Aging Time is user-conÞgurable through the Device Aging Time window.

To alter the Aging Time for Dynamic and Learned entries:

1.Click the I-bar cursor ( ) next to the Device Aging Time ﬁeld. The Device Aging Time window, Figure 2-19, will appear.
