Table 8-48: Parameters displayed in the output of the show mstp msti command
Parameter Meaning
MSTI The instance number of the spanning tree.
Bridge Identifier The unique Bridge Identifier of the switch. This
parameter consists of two parts, one part is derived
from the switch’s unique MAC Address, and the
other part is the priority value entered for the switch.
Bridge Role The role of the bridge in the spanning tree. This can
be either root bridge or designated bridge.
VLAN Members A list of the VLANs that are mapped to a specified
multiple spanning tree instance.
Regional Root Identifier The bridge identifier of the root bridge for the MSTI
in an MST region.
Designated Bridge The bridge identifier for the transmitting bridge for
the spanning tree.
Root Path Cost The path cost to the regional root.
Root Port The port number of the root port for the switch. This
parameter is invalid if the switch is the root bridge. In
this situation n/a will be displayed.
Time Since Topology Change The time elapsed, in seconds, since the last topology
change.
Topology Change Count The number of times that the topology has changed
since the bridge was powered or initialised.
Topology Change The indication whether the topology is in the middle
of changing.
