Using the BayStack 450 10/100/1000 Series Switch3-114 309978-D Rev 01Participation Allows you to configure any (or all) of the switch ports for spanning tree participation.When an individual port is a trunk member (see Trunk field), changing this setting for oneof the trunk members changes the setting for all members of that trunk. You shouldconsider how this can change your network topology before you change this setting (see“MultiLink Trunking Configuration Rules” on page 1-90).The Fast Learning parameter is the same as Normal Learning, except that the statetransition timer is shortened to 2 seconds.Default Normal LearningRange Normal Learning, Fast Learning, DisabledPriority This read-only field is a bridge spanning tree parameter that prioritizes the port’s lowestpath cost to the root. When one or more ports have the same path cost, the STA selectsthe path with the highest priority (lowest numerical value). See also Path Cost.Default 128Range 0 to 255Path Cost This read-only field is a bridge spanning tree parameter that determines the lowest pathcost to the root.Default 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 65535State 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 participatein the STA and transitions to the Forwarding state (the default). When the Participationfield is set to Normal Learning or Fast Learning, the port transitions from the Disabledstate through the Blocking, Listening, and Learning states before entering theForwarding state.Default Topology dependentRange Disabled, Blocking, Listening, Learning, ForwardingTable 3-39.
