  1. Run the display mpls te tunnel-interface command and check whether the Tunnel State Desc field is displayed as UP.

    • If so, go to step 2.

    • If not, see "TE Tunnel Is Down" in the Huawei AR100&AR120&AR150&AR160&AR200&AR1200&AR2200&AR3200&AR3600 Series Enterprise Routers MPLS Troubleshooting.

  2. Run the ping lsp te tunnel interface-number command on the ingress of the protection tunnel to check whether traffic runs properly.

    • If so, go to step 3.

    • If not, see "Host Cannot Transmit Packets Along an LSP" in the Huawei AR100&AR120&AR150&AR160&AR200&AR1200&AR2200&AR3200&AR3600 Series Enterprise Routers MPLS Troubleshooting.

  3. Check whether the physical link over which the tunnel is set up is faulty.

    • If so, repair the physical link.

    • If not, go to step 4.

  4. Collect alarm information and configuration information, and then contact technical support personnel.
  5. End.
