4.4Fault Diagnosis and Troubleshooting of GK Client

Fault 1: The register of GW on GK Server end fails.

Troubleshooting: Please follow the following steps:

zFirst, use ping command to check that it can interwork with GK Server on network layer.

zUse show running-configcommand to check that gateway command takes effect.

zCheck that GK Server end gatekeeper is activated.

Check that GK Server end has configured the area.
