output definitions
Msti The Multiple Spanning Tree Instance (MSTI) instance number. Config-
ured through the
bridge msti command. Note that MSTI 0 also repre-
sents the CIST instance that is always present on the switch.
Port The slot number for the module and the physical port number or a logi-
cal port. If the slot number is 0, then the port number refers to a link
aggregate logical port number (e.g., 0/31).
Oper St The port operational state as defined by application of the Spanning
Tree Protocol. Possible port operational states include: disabled, block-
ing, learning, and forwarding.
Path Cost The contribution of this port to the path cost towards the Spanning Tree
root bridge that includes this port. Path cost is a measure of the distance
of the listed port from the root bridge in the number of hops. Config-
ured through the
bridge slot/port path cost command.
Role The role of the port for this Spanning Tree instance. Possible port roles
are:
root, designated, alternate , and backup .
