Figure 2-11. The Port Source Address List
To view a port’s Source Address List:
1.
Display the Port menu by clicking mouse button 3 in the appropriate Port 
Status box.
2.
Drag down to Source Address List and release.
The Source Address List window displays addresses of all devices that have 
transmitted packets that were detected by the selected port within a time period 
less than the Source Address Table’s (SAT) defined ageing time (addresses that 
have not transmitted a packet during one complete cycle of the ageing timer will 
be purged). The Ageing Timer is user-configurable; see Setting the Ageing Time 
in the Source Address chapter, later in this manual. The List window can display 
about ten addresses at once; use the scroll bar to the right of the List window to 
view additional addresses, if necessary.
Since the SAT is constantly changing as old entries are aged out and new ones 
learned from the network, you should occasionally update a displayed list by 
clicking mouse button 1 on the 
button. Once displayed, the list is static
and will not reflect recent changes. The displayed number of Active Users is also 
static; this field will also update when you click on 
.
Managing the Hub
In addition to the performance information described in the preceding sections, 
the Hub View also provides you with the tools you need to configure your 
HUBStack and keep it operating properly. Hub management functions include 
setting polling intervals, enabling ports at the module and port level, and 
disabling ports at the port level.
