DescriptionField
Spanning Tree Bridge Status
The current operational state of the bridge (enabled or disabled).Spanning Tree
The current protocol version of the bridge (STP or RSTP).Spanning Tree Version
MAC address of the switch.Switch MAC Address
The configured spanning tree priority of the switch.Switch Priority
The current Max Age bridge parameter setting.Max Age
The current Forward Delay bridge parameter setting.Forward Delay
MAC address of the current Root bridge.Root MAC Address
Spanning Tree priority of the current Root bridge.Root Priority
The sum of the Port Path costs on the least cost path to the Root bridge. For the
Root bridge this is zero.
Root Path Cost
The port on the switch that forwards traffic toward the Spanning Tree root.Root Port
Number of topology changes since STP was enabled.Topology Change Count
Time since last topology change was detected.Time Since Last Change
Spanning Tree Interface Status

Interfaces with the TCN Guard parameter currently set.TCN Guarded Interfaces
Interfaces with the BPDU Guard parameter currently set.BPDU Protected Interfaces
Interfaces with the BPDU Filter parameter currently set.BPDU Filtered Interfaces
The port number.Interface
The priority and port index used by the Spanning Tree protocol.Interface ID
The current Spanning Tree port role. The port role can be one of the following
values:
Role
• RootPort—A forwarding port that is the best port from non-root bridge to
Root bridge.
• DesignatedPort—Each LAN segment has one designated port, a single
bridge port to which packets destined toward the Root bridge are sent.
• AlternatePort—When the Designated port is currently on a different bridge,
the Alternate Port is a port on this bridge that may become the Designated
port if needed.
• BackupPort—When the Designated port is currently a different port on this
bridge, the Backup port is a port on this bridge that can become the
Designated port if needed.
• DisabledPort—Not strictly part of the Spanning Tree protocol; a network
administrator can manually disable the port.
The current Spanning Tree port state. The port state can be one of the following
values:
State
• Blocking—A port that may cause a switching loop, no user data is sent or
received but it may go into forwarding mode if the other links in use were
