Description

Lost connection to a site and seeing a lot of ARP Failures.

Symptoms

Alerts for 'WAN Edge ARP Failure'

Loss of connectivity

Solution

If SSR does not receive a response from its ARP queries, this is expected behavior. By default, we send an ARP query every 5 seconds.


  • Verify missing responses in dynamic pcaps
  • Check connected devices to the port or the network path/upstream to see why the ARP responses are not being received
  • The behavior should go away once we start receiving responses again
