I have ACE 4710, I have configured the load balancing for the Web Portal. But I am not able to configure the Stickness. Below is the configuation of load balancing.



rserver host ITSMWeb_1
  description ITSMWeb-1
  ip address 192.168.200.161
  inservice
rserver host ITSMWeb_2
  description ITSMWeb-2
  ip address 192.168.200.162
  inservice


serverfarm host SF_ITSM_Web_Server
  probe ITSMWeb_PROBE_80
  rserver ITSMWeb_1
    inservice
  rserver ITSMWeb_2
    inservice

  replicate sticky
  serverfarm SF_ITSM_Web_Server


class-map match-any ITSM_Web_Server
  2 match virtual-address 172.23.15.163 any


policy-map type loadbalance first-match PM_LB_ITSM_Web_Server
  class class-default
    serverfarm SF_ITSM_Web_Server

  service-policy input PM_ITSM_MAPP_Server
  service-policy input PM_BYPASS_FOR_LAN_HTTP
  service-policy input PM_BYPASS_HTTP
  service-policy input PM_MAIN_BCPROXY
  no shutdown



I can do the remote desktop, ping, telnet on port 80 but not able to get the sticky in function. Due to this stickiness my authentication is not working.


Please let me know what I am missing.

Hi,


You've defined a sticky serverfarm, but you haven't created a policy that refers to it.


policy-map type loadbalance first-match PM_LB_ITSM_Web_Server
  class class-default
    serverfarm SF_ITSM_Web_Server


should read:


policy-map type loadbalance first-match PM_LB_ITSM_Web_Server
  class class-default
    sticky-serverfarm ITSM-STICKY

My experience with load balancing ITSM has been that you have to use the JSESSIONID for stickiness.
