Participation Allows you to configure any (or all) of the switch ports for Spanning tree participation.
When an i ndivi dual p ort is a trunk me mber (s ee Trunk field) , cha nging this set ting f or one
of the trunk members changes the setting for all members of that trunk. You should
consi der how this ca n c han ge you r ne twork topology before you change th is se tting (see
MultiLink Trunking Configuration Rules” on page 1-69).
The Fast Learning parameter is the same as Normal Learning, except that the state
transition timer is shortened to 2 seconds.
Default Value Normal Learning
Range Normal Learning, Fast Learning, 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 por ts 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.
Default Value 10 or 100 (1 for gigabit port)
Path Cost = 1000/LAN speed (in Mb/s)
The higher the LAN speed, the lower the path cost.
See also Priority.
Range 1 to 65535
State This read-only field indicates the current port state within the spanning tree network.
Each p ort can tr ansi tion to va rious states , as determined b y th e P articipation field s etting.
For exa mpl e , when the Participation fi eld is set to Disabl ed, the p ort does not pa rtic ipa te
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.
Default Value Topology dependent
Range Disabled, Blocking, Listening, Learning, Forwarding
