problem description:
root cause:
- The network is faulty.
- GK registration settings are inconsistent.
- The IP address of the MCU is in the restricted network segment of the GK.
solution description:
- The network is faulty.
Run ping to check the connection between the GK and MCU, and ask the network administrator to check the network and rectify the fault.
- GK registration settings are inconsistent.
Log in to the MCU using the CLI. Run display gk to check the parameters used for GK registration, specifically, whether GK enable is set to enable, and whether the GK IP address is correct.
If the preceding settings are inconsistent with those on the GK, run system-view gk-config to change the settings. After the change, ensure that the settings on the MCU and the GK are consistent.
- The IP address of the MCU is in the restricted network segment of the GK.
Change the restricted network segment of the GK.
