Field Descri
p
tion
Bridge ID
Bridge ID, which comprises the device's priority in the MSTI and its MAC address. For
example, in output "32768.000f-e200-2200," the value preceding the dot is the
device's priority in the MSTI, and the value following the dot is the device's MAC
address.
Bridge times
Major parameters for the bridge:
• Hello—Hello timer.
• MaxAge—Maximum age timer.
• FwdDelay—Forward delay timer.
• MaxHops—Maximum hops within the MST region.
Root ID/ERPC CIST root ID and external path cost (the path cost from the device to the CIST root).
RegRoot ID/IRPC
CIST regional root ID and internal path cost (the path cost from the device to the CIST
regional root).
RootPort ID Root port ID. "0.0" indicates that the device is the root and there is no root port.
BPDU-Protection Global status of the BPDU guard function.
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 since 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.
