Setting the Link Type for a Port

Setting the Link Type for a Port

Context

P2P links can implement rapid convergence. If the two ports connected by a P2P link are root or designated ports, they can transition to the Forwarding state quickly by sending Proposal and Agreement packets. This reduces the forwarding delay.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The view of an Ethernet interface participating in STP calculation is displayed.

  3. Run:

    stp point-to-point { auto | force-false | force-true }

    The link type is set for the interface.

    By default, an interface automatically identifies whether it is connected to a P2P link. P2P links implement rapid network convergence.

    • If the Ethernet interface works in full-duplex mode, the interface is connected to a P2P link. In this case, force-true can be specified in the command to implement rapid network convergence.

    • If the Ethernet interface works in half-duplex mode, you can run the stp point-to-point force-true command to forcibly set the link type to P2P.
