2-20 Managing the Hub
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.
