This counter tallies the total number of internal ARP Get requests processed, referring to lookups against the device's own ARP cache rather than requests sent over the wire. An admin uses this as an indicator of how often internal firmware processes are querying the ARP table, for example to resolve a next-hop address before forwarding traffic. A high arpGetReqs count relative to arpCacheSize would suggest the cache is being consulted heavily and might benefit from a larger size.
