This topic explains why connection failures occur between a Smart Access Gateway (SAG) device and a switch, and provides solutions.
- You cannot ping the ports of the SAG device through a switch.
- On the Port Alloc page of the web console, the indicators are red.
- When the Open Shortest Path First (OSPF) protocol is configured for dynamic routing, the indicators are red on the configuration page of the web console.
- On the Home page of the web console, no route type is configured for the target CIDR block.
- The cable that connects the SAG device to the switch is faulty.
- The port of the switch is disabled.
- IP address configurations of the SAG device and the switch are incorrect.
- Check whether the cable that connects the SAG device and the switch is faulty. Make sure that the indicators of the ports are on.
- Check whether the port of the switch is enabled.
- Check whether the IP address of the switch port and the SAG device port fall into the same CIDR block.
- If the OSPF protocol is configured, check whether the configurations of the OSPF port
and the SAG device port are the same.
The parameters include: Area ID, Hello Time, Dead Time, Authentication Type, Router ID, Area Type. Make sure that all directly connected CIDR blocks have advertised routes.
