Creating and Enabling an RRPP Ring

Creating and Enabling an RRPP Ring


You need to manually add nodes to an RRPP ring and configure an interface role for each node.

The RRPP ring can be activated only when both the RRPP ring and the RRPP protocol are enabled on all the switches on an RRPP ring.


STP has been disabled on the interfaces that need to be added to the RRPP ring. (By default, STP is enabled on all interfaces of the device.)


  1. Run system-view

    The system view is displayed.

  2. Run rrpp domain domain-id

    The RRPP domain view is displayed.

  3. Run ring ring-id node-mode { master | transit } primary-port interface-type interface-number secondary-port interface-type interface-number level level-value

    An RRPP ring is created.

    Level 0 indicates the major ring, and Level 1 indicates a sub-ring.

    • A domain contains only one major ring. Before creating a sub-ring, you must create the major ring.
    • The master node on the sub-ring cannot server as the edge node or the assistant edge node.
    • A maximum of 24 rings can be created on the S5720EI, S5720HI, S5720I-SI, S5720S-SI, S5720SI, S5730HI, S5730S-EI, S5730SI, S6720EI, S6720HI, S6720S-EI, S6720S-SI, and S6720SI, and 16 rings on other models.
    • Before adding an interface to a RRPP ring, disable port security on the interface; otherwise, loops cannot be prevented.

  4. Run ring ring-id node-mode { edge | assistant-edge } common-port interface-type interface-number edge-port interface-type interface-number

    An edge node and an assistant edge node on the RRPP sub-ring are configured.

    The common interfaces on the edge node and assistant edge node must be located on the major ring.

    The system automatically sets the level of the ring where the edge node and assistant edge node reside to 1.

  5. Run ring ring-id enable

    The RRPP ring is enabled.
