Description
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.
Description
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).
