Persistence Not Working

Hi,

 

 

For the following VIP, persistence is not working..

 

 

virtual syz-443

 

pool syzpl-443

 

destination 20.20.12.25:https

 

ip protocol tcp

 

vlans 25 enable

 

profiles tcp-profile

 

persist persist-source-addr-syz

 

 

 

http://20.20.12.25/lb/on.txt is giving different server every minute when persistence is set to 600 sec.

 

 

any help here would be great on what is causing this?

    Just taking a quick look at your posted config, it seems as though your destination is https but the URL you posted is http. Is there another Virtual Server using http without persistence?

    i noticed the following also..

     

     

    persist-source-addr-syz - IS the custom profile...AND

     

     

    persist-default-syz - Is the default profile

     

     

    Although, the persist-source-addr-syz is set for timeout vlaue of 600,

     

     

    the persist-default-syz profile seems to be having no setting of timeout value

     

     

    b profile persist-default-syz list

     

    profile persist-default-syz

     

    defaults from sourceaddr

     

     

    As no timeout setting is defined the custom profil persist-source-addr-syz , must be inheriting timeout settings from the parent profile.

     

    and therefore persistence is not sticking till 600 secs.

     

     

    Could this be the reason?
