Adding an Interface to an MSTP Process

Adding an Interface to an MSTP Process

Context

After being added to MSTP processes, interfaces can participate in MSTP calculation.
  • The links connecting MSTP—enabled devices and access rings are called access links.

  • The link shared by multiple access rings is called a shared link. Interfaces on this shared link participate in MSTP calculation in multiple access rings and MSTP processes.

Procedure

  • Adding an interface on an access link to an MSTP process
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The Ethernet interface view is displayed.

      The interface specified in this command must be the interface that connects the device and the access ring.

    3. Run stp binding process process-id

      The interface is added to the specified MSTP process.

    4. Run commit

      The configuration is committed.

  • Adding an interface on a shared link to an MSTP process
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The view of the Ethernet interface that participates in spanning tree calculation is displayed.

      The interface specified in this command must be an interface on the shared link between the devices configured with MSTP multi-process. It cannot be an interface that connects an access ring and device.

    3. Run stp binding process process-id1 [ to process-id2 ] link-share

      The interface is added to multiple MSTP processes to complete MSTP calculation.

      NOTE:

      In an MSTP process where there are multiple shared links, run the stp enable command in the MSTP multi-instance view. On an interface that is added to an MSTP process in link-share mode, run the stp enable command in the interface view.

    4. Run commit

      The configuration is committed.
