This topic explains why an SAG-1000 device cannot connect to a local client in the same CCN instance and how to troubleshoot it.

Symptoms

An SAG-1000 device cannot connect to a local client in the same CCN instance.

Causes

  • The link between the terminal and the SAG is faulty.
  • The VPN link between the SAG and Alibaba Cloud is faulty.
  • The network environment of the target PC is faulty.
  • The network of the service provider is faulty.
  1. Log on to the Smart Access Gateway console.
  2. Click the ID of the target Smart Access Gateway (SAG) instance and check whether the SAG is the Ready state.
    • If the SAG is offline, see The SAG is offline for troubleshooting.
    • If the SAG is ready, proceed to 3.
  3. Log on to the switch console to check the connectivity between the SAG and the switch.
    • If access is provided through static routes, ping the IP address of each interface on the SAG from the switch. If you cannot ping an interface, see Link failure between SAG-1000 and the switch to restore the connection to the interface.
    • If the SAG is stand-alone, check whether the second or third indicator on the right is lit yellow or flashing.
      • If the second indicator is lit yellow or flashing, the SAG has a software fault. Open a ticket for technical support.
      • If the third indicator is lit yellow or flashing, the VPN tunnel between the SAG and Alibaba Cloud is unavailable. Open a ticket for technical support.

      For more information, see SAG indicators.

  4. Repeat the preceding steps to check the SAG in the network environment of the target PC. If the problem persists, open a ticket for technical support.
