OCF_HEARTBEAT_SENDAR(7)	      OCF resource agents      OCF_HEARTBEAT_SENDAR(7)

NAME
       ocf_heartbeat_SendArp - Broadcasts unsolicited ARP announcements

SYNOPSIS

       SendArp [start |	stop | monitor | meta-data | validate-all]

DESCRIPTION
       This RA can be used _instead_ of	the IPaddr2 or IPaddr RA to send
       gratuitous ARP for an IP	address	on a given interface, without adding
       the address to that interface. For example, if for some reason you
       wanted to send gratuitous ARP for addresses managed by IPaddr2 or
       IPaddr on an additional interface.

       nic

       background
	   Send	ARPs in	background. Set	to false if you	want to	test if
	   sending ARPs	succeeded.

	   (optional, boolean, default true)
