Description
Bridge ID, which contains the device's priority and MAC address. For example, in
output 32768.000f-e200-2200, the value preceding the dot is the device's priority.
The value following the dot is the device's MAC address.
Major parameters for the bridge:
•
Hello—Hello timer.
•
MaxAge—Maximum age timer.
•
FwdDelay—Forward delay timer.
•
MaxHops—Maximum 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).
VLAN root ID and root path cost (the path cost from the device to the VLAN root
bridge).
Root port ID. The value 0.0 indicates that the device is the root and there is no root
port.
