Spanning Tree Port Configuration screen fields
Field
Description
Port
Indicates the switch port numbers, from 1 to 16, that correspond to the field settings in
that row of the screen (for example, the field settings in row 2 apply to switch port 2).
that row of the screen (for example, the field settings in row 2 apply to switch port 2).
Note that the settings in the All row (bottom row) affect all 16 switch ports.
Participation
Allows you to prevent any (or all) of the switch ports from participating in the STA.
Default Value
Enabled
Range
Enabled, Disabled
Priority
This read-only field is a bridge spanning tree parameter that prioritizes the port’s lowest
path cost to the root. When one or more ports have the same path cost, the STA selects
the path with the highest priority (lowest numerical value). See also Path Cost.
path cost to the root. When one or more ports have the same path cost, the STA selects
the path with the highest priority (lowest numerical value). See also Path Cost.
Default Value
128
Range
0 to 255
Path Cost
This read-only field is a bridge spanning tree parameter that determines the lowest path
cost to the root.
cost to the root.
Default Value
10 or 100
Path Cost = 1000/LAN speed (in Mb/s)
The higher the LAN speed, the lower the path cost.
See also Priority.
See also Priority.
Range
1 to 65535
State
This read-only field indicates the current port state within the spanning tree network.
Each port can transition to various states, as determined by the Participation field
setting. For example, when the Participation field is set to Disabled, the port does not
participate in the STA and transitions to the Forwarding state (the default). When the
Participation field is set to Enabled, the port transitions from the Disabled state through
the Blocking, Listening, and Learning states before entering the Forwarding state.
