Specify the delay, in milliseconds, between each peer
notification (gratuitous ARP and unsolicited IPv6 Neighbor
Advertisement) when they are issued after a failover event.
- This delay should be a multiple of the link monitor interval
- (arp_interval or miimon, whichever is active). The default
- value is 0 which means to match the value of the link monitor
- interval.
+ This delay should be a multiple of the MII link monitor interval
+ (miimon).
+
+ The valid range is 0 - 300000. The default value is 0, which means
+ to match the value of the MII link monitor interval.
prio
Slave priority. A higher number means higher priority.
