● Bridge Status
Shows the status of the bridge, e.g. whether or not the device is the root bridge.
● Regional Root Priority (only available with MSTP)
For a description, see Bridge Priority / Root Priority
● Regional Root Address (only available with MSTP)
Shows the MAC address of the device.
● Regional Root Cost (only available with MSTP)
Shows the path costs from the regional root bridge to the root bridge.
The table contains the following boxes:
● Port
Shows the port via which the device communicates.
● Role
shows the status of the port. The following values are possible:
– Disabled
– Designated
– Alternate
– Backup
– Root
– Master
● State
Displays the current status of the port. The values are only displayed. The parameter
depends on the configured protocol. The following statuses are possible:
– Discarding
– Listening
– Learning
– Forwarding

The port was removed manually from the spanning tree and will no longer be taken
into account by the spanning tree.
The ports leading away from the root bridge.
The port with an alternative route to a network segment
If a switch has several ports to the same network segment, the "poorer" Port becomes
the backup port.
The port that provides the best route to the root bridge.
This port points to a root bridge located outside the MST region.
The port receives BPDU frames. Other incoming or outgoing frames are discarded.
The port receives and sends BPDU frames. The port is involved in the spanning tree
algorithm. Other outgoing and incoming frames are discarded.
The port actively learns the topology; in other words, the node addresses. Other
outgoing and incoming frames are discarded.
Following the reconfiguration time, the port is active in the network. The port receives
and sends data frames.
