Configuring Network Interface Status Checks
When the device is deployed in Azure cloud, it may experience intermittent problems in communication with virtual hosts that may cause the virtual network interface (NIC) to "freeze". To overcome this issue, the device can periodically check the status of all network interfaces to detect if this condition exists and mitigate it by performing a maintenance reboot.
By default, the device monitors each interface every 10 seconds to ensure that both the receiving (Rx) and transmitting (Tx) counters are incrementing. If a counter remains unchanged, the device sends an ARP request and waits for a reply, which should increment the counters. If no ARP reply is received after 10 consecutive attempts (one per second), the device determines that the interface is "stuck" and automatically restarts. This device restart is logged as an exception in the Debug file.
This feature is applicable only to Mediant VE/CE deployed on Azure cloud.
