Field Description
CIST Bridge
CIST bridge ID, which comprises the device's priority in the CIST and its MAC
address. For example, in output "32768.000f-e200-2200," the value preceding
the dot is the device's priority in the CIST, and the value following the dot is the
device's MAC address.
Bridge Times
Major parameters for the bridge:
• Hello—Hello timer.
• MaxAge—Max age timer.
• FwDly—Forward delay timer.
• MaxHop—Max hops within the MST region.
CIST Root/ERPC CIST root ID and external path cost (the path cost from the device to the CIST root).
CIST RegRoot/IRPC
CIST regional root ID and internal path cost (the path cost from the device to the
CIST regional root).
CIST RootPortId
CIST root port ID. "0.0" indicates that the device is the root, and there is no root
port.
BPDU-Protection Global status of BPDU protection.
Bridge Config-
Digest-Snooping
Global status of Digest Snooping.
TC or TCN received Number of TC/TCN BPDUs received in the MSTI.
Time since last TC Time after the latest topology change in the MSTI.
[FORWARDING] The port is in forwarding state.
[DISCARDING] The port is in discarding state.
[LEARNING] The port is in learning state.
Port Protocol Status of the spanning tree feature on the port.
Port Role
Port role, which can be Alternate, Backup, Root, Designated, Master, or
Disabled.
