unbalanced pool , persistence problem

Hi Theizer, here's a couple of things to look at:

 

 

1) Set the cookie persistence profile to the standard 'cookie insert' (preconfigured) one rather than any custom created ones. Or at least ensure the BigIP inserts its own cookie name (don't specify one).

 

2) Ensure the f5 is configured to use client/server ssl profiles (as appropriate depending on SSL terminating on the LTM or not). this is to ensure the BigIP can decrypt the traffic correctly (although from your description this all sounds correct but it is worth checking).

 

3) Ensure the cookie is set to be a session cookie, or even better for test purposes set it to a long lifetime (like a week or more)

 

4) Ensure client browser accepts cookies.

 

5) Any iRules that could over-ride persistence? Or remove the cookie?

 

6) does the entry get written in the persistence table? ( try " b persist show all")

 

6) If you take a pcap on the LTM can you confirm that once you disconnect then reconnect, as a client, you send the cookie with your requests?

 

 

Let me know how you get on!
