Description
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 dot is the device's priority in the CIST, and the value
following the dot is the device's MAC address.
The bridge ID, which comprises the device's priority in VLAN 1 and its MAC
address. For example, in output information ―32768.000f-e200-2200‖, the
value preceding the dot is the device's priority in VLAN 1, and the value
following the dot 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).
VLAN root ID and root path cost (the path cost from the device to the root).
CIST root port ID. "0.0" indicates that the device is the root and there is no
root port.
VLAN root port ID. "0.0" indicates that the device is the root and there is no
root port.
