This object reflects the status of the interface's ARP support. A value of 'none' indicates that the interface does not support ARP. If the interface supports ARP but the interface is inactive, then the object will be set to a value of 'unknown'. If the interface is active and supports ARP, the object will be set to one of remaining values. A value of 'tcpipArp' indicates that the TCP/IP instance maintains the ARP cache entries and ARP counters for the interface. A value of 'offloadNoInfo' indicates that the interface maintains its ARP cache entries and ARP counters and the TCP/IP instance can not retrieve this information. A value of 'offloadArpInfo' indicates that the interface maintains its ARP cache entries and ARP counters but supports retrieval of this information by the TCP/IP instance. If the value of the MIB object is 'offloadArpInfo', then the ARP cache entries and ARP counters retrieved represent aggregated information and may reflect shared usage of the interface by more than one TCP/IP instance.
