NimbostratusCan I verify that VIP is doing the right job ?
I have a VIP A and VIP B, how can I verify that VIP is doing the right job:
Source IP: 1.1.1.1
VIP-A: 172.16.1.1:7002 Pool: Sever_7002
Health Monitor
X_monA : Send String Ord , Receive String Ord-Ok, Receive Disable String Ord-Disable
Y_monA : All Ports Time interval 10 , 31
Pool Member -1: 10.1.1.1:7002 Pool Member-2: 10.1.1.1:7002
Source Client: 1.1.1.1
VIP-B: 172.16.2.1:7002 Pool: Sever_7002
Health Monitor
X_monB: Send String Sync, Receive String: Sync-Ok Receive Disable String Sync-Disable
Y_monB: All Ports Time interval 10, 31
Pool Member -1: 10.1.1.1:7002 (down due to X_monB) Pool Member-2 : 10.1.1.1:7002
Issue is: Pool Member -1 is in VIP B down due to x_monB monitor, but backend team slates that they still gets the traffic on Pool Member-1 via VIP-B, how can I check from f5 prospective ? I tried tcpdump their it shows me push, ack, fin packets what no displays the send/receive string parameters in tcpdump

BigFootHi, it's strange that you have same pool on both VIPs, but different monitor. I think that pool name is different, then you can configure same pool members, but different monitors. If pool member is red, then LB is not sending any traffic to it. Why they are saying that traffic is from VIP B? LB is not sending VIP IP to the server, if you are not putting it to http header by iRule for example. I think it's rather traffic from VIP A and you can confirm it by tmsh command: show sys connection
jaiAdityaSinglaThanks Roman, but i found it its from VIP B by sys connection only, now i pinned the issue and fixed it its was cache related
