Hi, I am sorry for such long E-mail, but I have to figure out this for work and don't know anyone to ask. While searching Internet found this forum.
I am a CCNA and have been working with routers and switches for over 4 years, but recently at work was introduced to Cisco load Balancing switch 11500. This is a situation where I don't really have time to learn ..just need to do it. I hope, someone in this list can help me to figure this out. Here is the scenario: Client sends a request to the web server ( public url) , web server has two other servers ( with the application running) that he sends the requests to. The task is to make the CSS balance load these two app. server , but when the request comes to one server make it stay there until the session is over. The Cisco consultant was hired previously to help with the configuration. He configured web service and the apps service. Two application servers that need to be load balanced are parts of the apps service. He used arrow-point advanced load method.. here is how it specified in the content rule for the apps service. Ex: Owner Boston Content APPS VIP address x.x.x.x for the apps servers belongs to web server's subnet. Protocol TCP Port 80 URL "/*" Advanced-balance arrowpoint-cookies Active The initial request comes from client to the web server and web server passes the request to CSS ( that how this Internet application works). CSS needs to load balance request between two application servers to process the request. The persistent part works o'k. When the request comes from the web server to CSS it returns the Arrowpoint cookie to one of the application servers and stays there until the session is over. No problem,, should be that way... The problem is that the next brand new request comes to the same server, and then next new request again to the same server... Then randomly, next time it can go to the other server and all the new connections again to that server... So it's not really load balancing between two servers What needs to be added? I wasn't present when this consultant was doing final testing and I was told that it worked. Now, it doesn't. Show configs are the same with what he put in... What can I check ? Why it's not doing balancing ... At first I thought that it should come from different clients, but it really doesn't matter as all requests come to web server first and them should go to different app servers from the same web server. So during this testing , I was initiating requests from the web server itself. I really need help... I need to present a solution after labor day weekend... Thank you in advance if anyone can help.
