Field Description
Bridge ID
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.
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).
VlanRoot ID/RPC
VLAN root ID and root path cost (the path cost from the device to the VLAN root
bridge).
RootPort ID
Root port ID. The value
0.0
indicates that the device is the root and there is no root
port.
