Source Address Functions
Figure 4-3. Port Source Addresses Window
The source address list window displays the MAC addresses of all devices that have transmitted packets through the selected port within a time period less than the SAT’s defined ageing time (addresses that have not transmitted a packet during one complete cycle of the ageing timer are purged). The Ageing Time is user-configurable; see Setting the Device Ageing Time, page 4-5.
NOTE |
You can create a text file which will add names to correspond to the source addresses that appear in the Source Addresses window. For more information on how this naming feature works, refer to the NetSight Element Manager User’s Guide.
Setting the Device Ageing Time
The source address list Ageing Time determines the minimum amount of time an inactive source address will remain in the Source Address Table before it is purged. The source address timer runs continuously beginning at the time the device is turned on (or the repeater channel is activated); source addresses that are added to the SAT during one timer cycle will remain in the table for the rest of the current cycle, and at least through the next complete cycle. If no packets have been received from that address during one complete cycle, the address will be purged from the table.
