Display the RSTP Status for a Port

Perform the following procedure to display the RSTP-related status information for a selected port.

Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. Display the RSTP status for a port:

    show spanning-tree rstp port status {sub-port]][,...][slot/all][all]}

    Note

    Note

    If your platform supports channelization for 40 Gbps ports and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
