Description: The number of packets dropped because there is no ARP entry in the ARP table.
What is cdmipDroppedPacketsNoArpEntry?
This counts packets dropped because there was no matching entry in the ARP table for the next-hop address. A rising count here typically means the modem has a route pointing at a next hop, via cdmipIpRouteNextHopAddress, that it cannot actually resolve to a MAC address, often because that next-hop device is down, misconfigured, or not actually present on the expected Ethernet segment. A route configured with a next-hop address of 192.168.1.1 that does not correspond to any actual device on that LAN segment would show up as a steadily climbing count here, since the modem can never successfully ARP for that address.
