Description
CIST bridge ID. It comprises the switch'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 switch's priority in the CIST, and the value
following the period is the MAC address of the switch.
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 switch to the CIST root).
CIST regional root ID and internal path cost (the path cost from the switch to the
CIST regional root).
