NimbostratusInactive node taking traffic
Hello All,
I have one VIP setup in which i can see node is down , but it still taking traffic. As i know e default behavior of F5 HLB, when it detects that a node is down, is to route new requests to a known good node and let existing sessions continue to go to the known bad node . So Is there any way that to stop the traffic immediately. Is any irule or any specific setting that i can apply for desired result ?
Thanks, Deepak

can you try LB::status and reject command?

Another option is to set the 'action on service down' pool setting to 'reject' so TMM will send a TCP reset when the pool member is marked down by a monitor.

I have vip setup , and using tool we are monitoring public ips form which traffic is coming to server. Since few days its stop working .I took tcpdumo using server ip and using tool I found that its showing only one ip form which traffic is coming to server. when I checked for that ip , I can see that ip is configured as snat.
