❏ Front panel display
The front panel graphic displays the image
of the connected switch, its LED panel,
and the active data ports.
The front panel LED display simulates the
IntraSwitch in real-time operating mode. It
approximates all switch activity as it
occurs.
❏ Legend bar
This is a bar which is located below the
simulated IntraSwitch panel. It describes
individual port activity indicated by the use
of colored lights within the port connector.
These lights indicate Spanning Tree state
(i.e., forwarding, blocking, etc.) of the indi-
vidual switched port as long as link is estab-
lished. If activity is occurring on the port,
the bar will display its current usage as fol-
lows:
■ Forwarding. This is a green LED
which indicates forwarding activity on
the selected port.
■ Listening/Learning. This is a yellow
LED which indicates an intermediate
Spanning Tree Mode prior to a forward-
ing or blocking decision. See Table 7-2.
■ Blocking. This is a red LED which
indicates that the port has detected a
data loop and is no longer switching
packets.
■ Disabled. This is a blue LED which
indicates that the port has been dis-
abled.
