to remove an IP address; arp flush allows users to clear arp cache; arp status allows users to
review current status for the arp table; arp accept allows to accept or reject the source
/destination MAC address; arp setCacheLife allows users to configure the duration in which
ARP caches can be stored on the system. If ip arp setCacheLife is set with “60”, it means you
have an ARP cache at 0 second. Sixty seconds later without any ARP messages received, the
system will think such ARP cache is expired. The system will issue a few ARP request to see if
this cache is still valid.
