CIST bridge ID, which comprises the device's priority in the CIST and its
MAC address. For example, in output information
"32768.000f-e200-2200", the value preceding the period (".") is the
device's priority in the CIST, and the value following the period is the
device's MAC address.
Major parameters for the bridge:
Hello: Hello timer
MaxAge: Max Age timer
FWDly: Forward delay timer
Max Hop: Max hops within the MST region
CIST root ID and external path cost (the path cost from the device to the
CIST root)
CIST regional root ID and internal path cost (the path cost from the device
to the CIST regional root)
CIST root port ID. "0.0" indicates that the device is the root and there is no
root port.
Indicates whether BPDU protection is enabled globally.
Indicates whether Digest Snooping is enabled globally on the bridge.
Number of received TC/TCN packets
