ARP Statistics Analysis of ARP traffic on this interface; In fields are for
traffic received on the interface and Out fields are for traffic sent on the
interface
ARP requests Number of ARP requests
ARP responses Number of ARP responses
Errors Total number of errors in all ARP packets
Discards Total number of discarded ARP packets
queue Hardware packet queue associated with the specified traffic class
and interface
Queue length Length of the queue, in bytes
Forwarded packets, bytes Number of packets and bytes that were
forwarded on this queue
Dropped committed packets, bytes Number of committed packets and
bytes that were dropped
Dropped conformed packets, bytes Number of conformed packets and
bytes that were dropped
Dropped exceeded packets, bytes Number of exceeded packets and
