Configuring the Rate for an Ethernet Interface

Configuring the Rate for an Ethernet Interface

Context

You can set the interface rate in either the auto-negotiation or non-auto negotiation mode.

  • In auto-negotiation mode, interfaces on both ends of a link negotiate their interface rates. You can set the auto-negotiation rate range to limit the negotiated rate. For example, if two interfaces negotiate to work at a rate of 100 Mbit/s, but they are required to work at a rate of 10 Mbit/s to prevent network traffic congestion, you can run the auto speed 10 command to set the rate of the interfaces to 10 Mbit/s.
  • In non-auto negotiation mode, you must set the rate for interfaces so that the two devices can communicate.

Procedure

  • Configuring interface rate in auto-negotiation mode
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The Ethernet interface view is displayed.

    3. Run auto speed { 10 | 100 | 1000 }*

      The rate is set for the Ethernet interface.

    By default, interfaces on both ends of a link negotiate their interface rates.

  • Configuring the interface rate in the non-auto negotiation mode
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The Ethernet interface view is displayed.

    3. Run undo negotiation auto

      The Ethernet interface is configured to work in non-auto negotiation mode.

    4. Run speed { 10 | 100 | 1000 | 10000 }

      The rate is set for the Ethernet interface.

    By default, an Ethernet interface works at the maximum rate. Specially, when a GE electrical interface works in non-auto-negotiation mode, its default rate is 100 Mbit/s, not the maximum rate 1000 Mbit/s supported by the GE interface.
