Unable to redirect to a different pool

Env : Big IP 9.4

 

I have configured the Below iRule and added it to Virtual Server

 

 

when LB_SELECTED {

 

if {([LB::server port] == 9931)}{

 

pool APILink_A

 

log local0. "Port 9931 Identified"

 

} elseif {([LB::server port] == 9933)} {

 

pool APILink_B

 

log local0. "Port 9933 Identified"

 

}

 

}

 

 

I am able to get the correct log based on the status of the port condition. but the F5 does not direct the traffic to the specified pool .

 

 

eg

 

 

When [LB::server port] == 9931 condition is satisfied, Pool APILink_A is not selected. But "Port 9931 Identified" is logged.

 

Any help you be appreciated.

    If you're using LB::server port, hasn't your traffic already hit a specific pool and the load balancing decision already been made?

     

     

    If you read the wiki on "pool," you'll notice the event isn't valid in LB_SELECTED even though it doesn't throw an error:

    Can you better explain what you're trying to accomplish here? It sounds like you have a VS and you want to send traffic to two different pools but I'm unsure of what you're trying to base that decision on.
