Troubleshooting Procedure

Troubleshooting Procedure

After commands are configured to troubleshoot faults, pay attention to the configuration validation mode to ensure that the configurations take effect. Unless otherwise specified, this manual defaults to the two-phase validation mode.

  • In immediate validation mode, the configuration takes effect immediately after you run a command and press Enter.
  • In two-phase validation mode, you must run the commit command after commands are configured to commit the configuration.

Save the results of each troubleshooting step, so you can provide related information to Huawei technical support if your troubleshooting fails.

Procedure

  1. Check whether an administrative VLAN is configured.

    Run the display current-configuration configuration trill | include admin-vlan command to check whether an administrative VLAN is configured.

    • If no administrative VLAN is configured, run the admin-vlan vlan-id command to configure it.

    • If an administrative VLAN has been configured, run the display vlan command to check whether the configured administrative VLAN is established. If the configured administrative VLAN is not established, run the vlan command to establish the VLAN. If the configured administrative VLAN is already established, go to Step 2.

  2. Check whether the administrative VLANs configured at the two ends are the same.
    • If the administrative VLANs configured at the two ends are different, run the admin-vlan vlan-id command on either end to modify the administrative VLAN so that the administrative VLANs configured at the two ends are the same.

    • If the administrative VLANs configured at the two ends are the same, go to Step 3.

  3. Check whether TRILL traffic is forwarded properly.

    Run the display trill route [ nickname ] command or the display trill mroute [ vlan-id ] command to check whether there are TRILL routes to the other end.

  4. Collect the following information and contact technical support personnel.

    • Results of the preceding troubleshooting procedure
    • Configuration files, log files, and alarm files of the devices
