Issue in Failover of pool member

But if the source based persistence is used then it may take 5 min to hit the client traffic on next available poolmember when the 1st pool member goes down and the requirement is clients traffic should switchover to next available pool member within 4 sec whenever the 1st pool member goes down...

If your requirement is failover traffic to pool member B only if pool member A goes down? If Yes to the question then you need to go with Ratio load balance method and no need to use persistence.

Ration method:

Pool A --100% Pool B --0%

Hope this helps.

Thanks Raghvendra, but after setting lb method to ratio , will the Failover take place in 4 sec

anyways I'll set probe interval timings to 1 sec and probe timeout value to 4 sec , will this help me in achieving my target of Failover in 4 sec?

Yes. It should be immediately.

Thanks Raghvendra.
