Changing a port priority

Follow these steps to change the QoS priority of a specific port.

  1. Enter global configuration mode.
    
    device# configure terminal
    
  2. Enter interface configuration mode.
    
    device(config)# interface ethernet 1/1/1
    
  3. Set the port priority.
    
    device(config-if-e1000-1/1/1)# priority 7
    
    This step assigns priority 7 to untagged switched traffic received on port 1/1/1.
  4. Return to privileged EXEC mode.
    
    device(config-if-e1000-1/1/1)# end
    
  5. Verify the configuration.
    
    device# show interface brief

    The interface priority is listed under the heading Pri.
