Description
Shows if Spanning Tree is turned on or off for the switch.
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
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
value of the root bridge.
Forward Delay
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
, , or
learning forwarding
The State field in RSTP or MSTP mode can be one of the following:
(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.
