Using the SEHI Hub View

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.
