CSS load balancing issue

[gavin han]

Hi,

I've following configuration setup on CSS. users are complaning that the request isn't going to service1, it always goes to service2. (even though both services are up - if I check them on CSS). please advise what could be the issue.

service service1

  ip address 192.168.123.1
  protocol tcp
  port 80
  keepalive port 80
  keepalive type http
  keepalive uri "/test.asp"
   active

service service2

  ip address 192.168.123.2

  protocol tcp

  port 80

  keepalive type http

  keepalive uri "/test.asp"

  active

owner owner1

  content content1
    vip address 10.10.54.1
    protocol tcp
    port 80
    url "/*"
    balance weightedrr
    advanced-balance sticky-srcip
    add service service1
    sticky-inact-timeout 45
     add service service2
    active

Thanks...

Gavin,

Is the user connection proxied or NAT'd before it gets to the CSS VIP?

Since you're using sticky based on client source IP all the request will be sent to the same server

all the time (unless the timeout is reached) and proxy or NAT would be most likely the root of the issue.

You can also test with arrowpoint cookie as your sticky method and see if that alleviates the problem

HTH
