Source Route Configuration 4-61
Bridging
You can use the Set button at the bottom of the window to change the Hop Count
for the port, as explained in the section Making and Setting Changes, page 4-63.
The permissible value for this Þeld is 0 to 28.
Spanning Tree Expl.
This read-only Þeld displays the action currently being applied to Spanning Tree
Explorer frames received by the indicated port. This Þeld will appear in one of
two ways:
¥ If the Spanning Tree Mode for the bridge is set to Auto (as explained in the
following section), this Þeld will display the Spanning Tree Port State for the
indicated port.
If set to Auto, the device is subject to the Spanning Tree Algorithm. Each port
will treat incoming frames according to its current Spanning Tree bridging
state (i.e., Forwarding, Disabled, Listening, Learning, Blocking, or Broken).
¥ If the Spanning Tree Mode is set to Manual (as explained in the following
section) this Þeld will display either Enabled or Disabled as the Spanning Tree
Port Enable State for the indicated port.
Bridge Number
The Bridge Number uniquely identiÞes a bridge port when more than one bridge
is used to span the same two segments. The Bridge Number should be in the
range of 0 to 15.
You can use the Set button at the bottom of the window to change the bridge
number of the port, as explained in the section Making and Setting Changes,
page 4-63. Current source routing protocols allow a range of 0 to 15 (0ÐF
hexadecimal) for the bridge number identiÞer. If no bridge number is assigned to
the device, a default value of 1 will appear in this Þeld.
