Table 18 Switch Spanning Tree Group Information controls
Control Description
Path Cost Displays the cumulative path cost to the Current Root.
Root Port Displays the switch port that is connected to the Current Root.
Max Age 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.
Hello Time 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.
Forward Delay 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.
Hold Time Displays the minimum number of seconds that must elapse between transmissions
of consecutive configuration BPDUs on a port.
Topology Change Counts Displays the number of times the spanning tree topology has changed.
Aging Time 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.
Bridge Priority Controls which bridge on the network will become the STP root bridge.
Bridge Hello Time 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.
Bridge Max Age Specifies, in seconds, the maximum time the bridge waits without receiving a
configuration bridge protocol data unit before it reconfigures the STP network.
Bridge Forward Delay Specifies, in seconds, the amount of time that a bridge port has to wait before it
changes from learning state to forwarding state.
Bridge Aging Time 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 19 Switch Spanning Tree Port Information controls
Control Description
Port Displays the port number for each port’s STP information.
Spanning Tree State Shows if Spanning Tree is turned on or off for the port.
Port State
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).
