Identifying the Ports that are Connected to a Segment
You can find out what ports in the stack are connected to a segment
by clicking on that segment’s name button on any of the hubs:
■
If the hub’s segment is isolated from the cascade segment, only
ports that are connected to the hub’s segment are highlighted.
■
If the hub’s segment is connected to the cascade segment, all other
ports in the stack which are part of segments that are connected to
the same cascade segment, are highlighted.
The ports (and any transceiver module ports) that are part of the
segment, are highlighted with a dark blue surround. Click the name
button again to turn off the highlighting.
