Ping functionality is used to check whether the device can be reached from the Aeris portal or not. PING uses the ICMP protocol to test layer 3 (network) connectivity. If a device is in a current session, the device will be assigned an IP address. The PING command allows you to test connectivity to your devices from the Aeris platform. When a PING is successful, it means the device is up and able to accept TCP/IP connections.
When a PING fails, there are several reasons. The device may be offline or powered down. The device may be up, but there may be a routing issue between the Aeris platform and the device. There may be a port blocked on the device that isn't allowing PING to operate. There are a number of reasons that PING may fail, if you are unable to PING your device consistently, you may need to open a ticket with Aeris by e-mailing support@aeris.net
