we have this setup, 2 servers which are running 2 instances on each server. First instance is via port 9688 then second is via port 9443. The traffic flow runs in a way that users will hit the VIP via port 9688, F5 will then load balance between the 2 servers. Let say traffic is routed to server1, within the server1 it will it will connect to another url via port 9443. Take note these 2 (9688 and 9443) are both running in the same server.
Is there a way without using IRULE that when port 9443 is down (let say on server1), F5 will mark the node as DOWN?
You do not need an iRule. Just crate a new tcp monitor. Set Alias Service Port 9443 in this monitor. After that, assign it to the node which you wanna see down while not reaching via port 9443.
That is it.
Alias Service Port
Great. It works but I have did it under Pool not under node.
Thanks a lot.
