Set to "Root" if this bridge is the rootbridge.Port Num The port number of the interface.Pri The configured priority of the port. The default is 128.PortPath Cost Configured or auto detected path cost for port.P2P Mac Indicates if the port is configured with a point-to-point link:• T – The port is configured in a point-to-point link• F – The port is not configured in a point-to-point linkEdge Indicates if the port is configured as an operational edge port:• T – indicates that the port is defined as an edge port.• F – indicates that the port is not defined as an edge portRole The current role of the port:• Master• Root• Designated• Alternate• Backup• DisabledState The port’s current 802.1s state. A port can have one of the followingstates:• Forwarding• Discarding• Learning• DisabledDesignated Cost Port path cost to the root bridge.Max Hop cnt The maximum hop count configured for this instance.Root Hop cnt Hop count from the root bridge.TABLE 168 Output from Show MSTP (Continued)This field...
