Configuring the Auto-Negotiation Function

Configuring the Auto-Negotiation Function

Context

The auto-negotiation function allows interfaces on both ends of a link to select the same operating parameters by exchanging capability information. The parameters include the duplex mode and rate. When the negotiation succeeds, the two interfaces use the same duplex mode and work at the same rate. In non-auto-negotiation mode, the operating parameters must be set manually.

NOTE:
  • By default, GE interfaces do not support flow control auto-negotiation. You can run the flow-control negotiation command to configure flow control auto-negotiation.
  • GE optical interfaces do not support auto-negotiation function after FE optical modules are installed on the interfaces.
  • The GE interfaces on the AR2201-48FE, AR2202-48FE, AR2204-51GE-P, AR2204-51GE-R, AR2204-27GE-P, AR2204-27GE, AR2204E, AR2204E-D and AR2204 do not support flow control.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Configure the auto-negotiation function.

    • Run negotiation auto

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

    • Run undo negotiation auto

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

    By default, an Ethernet interface works in auto-negotiation mode.
