Troubleshooting Procedure

Context

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.
