The number that identifies the MST instance.
The bridge priority for the spanning-tree instance. This value affects
the likelihood that the bridge is selected as the root bridge. A lower
value increases the probability that the bridge is selected as the
root bridge.
The number of VLANs that are mapped to the MSTI. This number
does not contain any information about the VLAN IDs that are
mapped to the instance.
A unique value that is automatically generated based on the bridge
priority value of the MSTI and the base MAC address of the bridge.
When electing the root bridge for an MST instance, if the bridge
priorities for multiple bridges are equal, the bridge with the lowest
MAC address is elected as the root bridge.
Change
The amount of time that has passed since the topology of the MSTI
has changed.
The bridge identifier of the root bridge for the MST instance. The
identifier is made up of the bridge priority and the base MAC
address.
The path cost to the designated root for this MST instance. Traffic
from a connected device to the root bridge takes the least-cost
path to the bridge. If the value is 0, the cost is automatically
calculated based on port speed.
The port on the bridge with the least-cost path to the designated
root for the MST instance.
