{slot/port[/sub-port][-slot/port[/sub-port]][,...]}: Shows RSTP port statistics. {slot/port[/sub-port][-slot/port[/sub-port]][,...]} identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If your platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

Default

None

RxRstBpduCount	The number of RSTP BPDUs received on this port.
RxConfigBpduCount	The number of configuration BPDUs received on this port.
RxTcnBpduCount	The number of TCN BPDUs received on this port.
TxRstBpduCount	The number of RSTP BPDUs transmitted by this port.
TxConfigBpduCount	The number of Config BPDUs transmitted by this port.
TxTcnBpduCount	The number of TCN BPDUs transmitted by this port.
InvalidRstBpduRxCount	The number of invalid RSTP BPDUs received on this port. A trap is generated on the occurrence of this event.
InvalidConfigBpduRx Count	The number of invalid configuration BPDUs received on this port. A trap is generated on the occurrence of this event.
InvalidTcnBpduRxCount	The number of invalid TCN BPDUs received on this port. A trap is generated on the occurrence of this event.
