Parameter description:
Port:
The physical port index; available value is 1 to 24.
Instance :
Every MRSTP instance must have a unique instance ID.
Status :
To display the port join MRSTP status.
Role :
If “Yes” causes the Port not to be selected as the Root Port for the CIST or any
MSTI, even if it has the best spanning tree priority vector. Such a Port will be
selected as an Alternate Port after the Root Port has been selected. This
parameter is “None” by default. If set, it can prevent spanning tree connectivity.
It is set by a network administrator to prevent bridges external to a core region
of the network from influencing the spanning tree active topology, possibly
because those bridges are not under the full control of the administrator.
Path Cost :
Displays the port path cost. If the path cost shows zero, the STP will get the
recommended value resulting from auto-negotiation of the link accordingly and
display this value in the Path Cost Status field. Otherwise, it may show the
value that the administrator set up in Configured Path Cost and Path Cost
Status.
Priority :
