The following table describes the Switch Spanning Tree Group Information controls: Table 16 Switch Spanning Tree Group Information controls Control Description Spanning Tree State Shows if Spanning Tree is turned on or off for the switch. VLANs Current Root Path Cost Root Port Max Age Hello Time Forward Delay Hold Time Topology Change Counts Aging Time Bridge Priority Bridge Hello Time Bridge Max Age Bridge Forward Delay Bridge Aging Time Displays the VLANs that are members of this Spanning Tree Group. Displays information about the root bridge for the Spanning Tree. Information includes the priority (hex) and MAC address of the root. Displays the cumulative path cost to the Current Root. Displays the switch port that is connected to the Current Root. Specifies, in seconds, the maximum time the bridge waits without receiving a configuration bridge protocol data unit before it reconfigures the STP network. If the bridge is not the root bridge, it uses the MaxAge value of the root bridge. Specifies, in seconds, how often the root bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge uses the root bridge hello value. Specifies, in seconds, the amount of time that a bridge port has to wait before it changes from learning state to forwarding state. If the bridge is not the root bridge, it uses the Forward Delay value of the root bridge. Displays the minimum number of seconds that must elapse between transmissions of consecutive configuration BPDUs on a port. Displays the number of times the spanning tree topology has changed. Specifies, in seconds, the amount of time the bridge waits without receiving a packet from a station before removing the station from the Forwarding Database. Controls which bridge on the network will become the STP root bridge. Specifies, in seconds, how often the root bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge uses the root bridge hello value. Specifies, in seconds, the maximum time the bridge waits without receiving a configuration bridge protocol data unit before it reconfigures the STP network. Specifies, in seconds, the amount of time that a bridge port has to wait before it changes from learning state to forwarding state. Specifies, in seconds, the amount of time the bridge waits without receiving a packet from a station before removing the station from the Forwarding Database. Switch Spanning Tree Port Information The following table describes the STP port parameters: Table 17 Switch Spanning Tree Port Information controls Control Description Port Spanning Tree State Port State Port Priority Port Cost Displays the port number for each port's STP information. Shows if Spanning Tree is turned on or off for the port. Shows the current state of the port. The state field can be blocking, listening, learning, forwarding, or disabled. The State field in RSTP or MSTP mode can be one of the following: Discarding (DISC), Learning (LRN), Forwarding (FWD), or Disabled (DSB). Helps determine which bridge port becomes the designated port. In a network topology that has multiple bridge ports connected to a single segment, the port with the lowest port priority becomes the designated port for the segment. Helps determine the designated port for a segment. Generally speaking, the faster the port, the lower the path cost. A setting of 0 indicates that the cost will be set to the appropriate default after the link speed has been auto negotiated. Dashboard 33
