Configure Port Speed

About this task

Manually configure the port speed.

Important

Important

If Auto-Negotiation is disabled and you change the speed on a port that results in a configuration mismatch in speed between two ports, VSP 4450 Series and VSP 4900 Series switches may show an incorrect operational status of "up" for the mismatched ports.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

    Note

    Note

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

  2. Configure the speed for one or more ports:
    speed {10|100|1000|10000|2500|25000|5000}

    or

    speed port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}] {10|100|1000|10000|2500|25000|5000}
