Output Fields

  • rx-arp-requests/tx-arp-replies, RX Requests/Tx Replies—Number of ARP requests received on the interface, and number of replies sent to these ARP requests.

  • arp-add-fails, Add Fails—Packets for which an ARP entry in the forwarding plane could not be created.
  • rx-arp-reply-drops, RX Reply Drops—Currently, the software does not increment this counter.
  • rx-arp-rate-limit-drops, RX Rate Limit Drops—Currently, the software does not increment this counter.
  • tx-arp-rate-limit-drops, TX Rate Limit Drops—Number of ARP packets generated by the forwarding plane that exceed the CPU rate limit, which is 16 ARP packets sent towards the CPU and 128 ARP packets send towards physical ports.
  • rx-arp-non-local-drops, RX Non-Local Drops—Received ARP packets that do not match the destination IP address of any local IP address.
  • tx-arp-request-fail—Packets that could not be transmitted because an ARP request for the MAC address corresponding to the destination IP address was unable to retrieve a MAC address.
  • tx-no-arp-drops, TX No ARP Drops—Packets dropped in the forwarding plane because of a missing ARP entry for a destination IP address.
