Seeing traffic when vip/ node are down, and have tcpdump's that validate that traffic is still passing.
Hello,
I have a very odd situation. I have a node configured to only respond on TCP port 8081 to incoming http traffic, with a very simple health monitor Get /health_check.txt \r\n. That seems to be working fine. However,
I disabled the VIP and the node and they show down in the network map. Running tcpdump on the F5 (11.4.1) I still see traffic being generated and the http page shows just fine. (and that is after clearing browser cache) In addition, I can telnet to the node on tcp port 8081 and get a response.
I guess my question is this, is the F5 caching the traffic when the VIP, server pool and node are in a disabled state? Has anyone seen this behavior before?
It has be scratching my head.
