After the Primary Port of a Transit Node on an RRPP Ring Network Becomes Down and Then Recovers, the Transit Node and Other Transit Nodes Cannot Register With the Master Node

After the Primary Port of a Transit Node on an RRPP Ring Network Becomes Down and Then Recovers, the Transit Node and Other Transit Nodes Cannot Register With the Master Node

Fault Symptom

After the primary port of a transit node on an RRPP ring network becomes down and then recovers, the transit node and other transit nodes cannot register with the master node.

Procedure

  1. Check the master node on the RRPP ring.

    Run the display rrpp verbose domain domain-id [ ring ring-id ] command in any view on each node on an RRPP ring to view the role of each node.

    If the value of Node Mode is Master, the node is the master node.

    Then go to step 2.

  2. Check whether MAC address entries and ARP entries of the master node are updated.

    Run the display mac-address and display arp all commands in any view of the master node on an RRPP ring to check the MAC address table and ARP table on the master node. Check whether there are MAC address entries and ARP entries of transit nodes that cannot register.

    • If there are no MAC address entries and ARP entries of transit nodes that cannot register, MAC address entries and ARP entries of the master node are not updated. Go to step 3.

    • If there are MAC address entries and ARP entries of transit nodes that cannot register, go to step 4.

  3. Check whether nodes on an RRPP ring use the same working mode.

    Run the display rrpp brief [ domain domain-id ] command in any view to view the RRPP configuration.

    Check whether the configuration contains the rrpp working-mode gb command. If the rrpp working-mode gb command has been executed on a node, the node uses the RRPP standard version. If the rrpp working-mode gb command is not executed on a node, the node uses Huawei proprietary version.

    • If the master node and other transit nodes use different working modes, run the undo rrpp enable command in the system view of the chassis switch to disable RRPP and deactivate all RRPP rings. Then run the rrpp working-mode { hw | gb } command to change the working mode of each node to be the same.

    • If the master node and other transit nodes use the same working mode, go to step 4.

  4. Collect alarms, logs, and location information, and then contact technical support personnel.
