The MSTI ID.
The slot number and port number of the port.
The port's current state for the MSTI. Possible values are:

Blocking – The port does not send or receive traffic, but does receive
BPDUs.
•
Learning – The port receives traffic but does not forward the traffic.

•
Listening – The port monitors BPDUs, but does not forward traffic
and does not learn the source MAC addresses of incoming frames.
•
Disabled – The port is disabled (not by MSTP).
The Regional Root ID component of the port's Port Priority vector for the
MSTI.
The Internal Root Path Cost component of the port's MSTI port priority
