you have configured ' advanced-balance sticky-srcip '

So each time you connect with the same source ip you are directed to the same server.

CSS just does what you configured it for.

Remove this command if you just want round-robin.

Gilles.

Hi:

Acceding of any client, always it connects to the server serv1, it is to say the client "a" is connected and it sends it serv1, client

"b" connects itself and also she sends it serv1; is to say to nonbalance to the second client to the other servidor serv2.

how many clients did you use for your test ?

Roundrobin is not perfect like connection 1 to server 1 and connection 2 to server 2.

You may see like 3 connections to server 1 and then 2 to server 2 and 1 to server 1 and then 2 to server 2.

In real production network this is ok and will give perfect roundrobin.

If you are in a lab environment, and using only a few clients, you may get incorrect result.

Try to generate many connections from many clients.

I you have many clients, capture a 'sho summary' and 'sho serv summary' and attach it to the discussion.
