The table has the following columns:
• Port
Shows the interfaces via which the device communicates.
• Role
Shows the status of the port. The following values are possible:
– Disabled
The port was removed manually from the spanning tree and will no longer be taken
into account by the spanning tree.
– Designated
The ports leading away from the root bridge.
– Alternate
The port with an alternative route to a network segment
– Backup
If a switch has several ports to the same network segment, the "poorer" Port
becomes the backup port.
– Root
The port that provides the best route to the root bridge.
– Master
This port points to a root bridge located outside the MST region.
• Status
Shows the current status of the interface. The values are only displayed. The
parameter depends on the configured protocol.
– Discarding
The port receives BPDU frames. Other incoming or outgoing frames are discarded.
– Listening
The port receives and sends BPDU frames. The port is involved in the spanning
tree algorithm. Other outgoing and incoming frames are discarded.
– Learning
The port actively learns the topology; in other words, the node addresses. Other
outgoing and incoming frames are discarded.
– Forwarding
Following the reconfiguration time, the port is active in the network. The port
receives and sends data frames.
• Oper. Version
Shows the compatibility mode of Spanning Tree used by the port.
• Priority
If the path calculated by the spanning tree is possible over several ports of a device,
the port with the highest priority (in other words the lowest value for this parameter)
is selected. A value between 0 and 240 can be entered for the priority in steps of 16. If
you enter a value that cannot be divided by 16, the value is automatically adapted.
The default is 128.
• Path Cost
This parameter is used to calculate the path that will be selected. The path with the
