    Hi Sohail,

     

    did you apply some kind of persistence to your virtual server?

     

    Thanks, Stephan

    Hi,

     

    Maybe there is priority group activation used? Or there is some flapping caused by monitor for one pool member?

    Hi Sohail,

    there are very few current connections only at all on your virtual server.

    (The bigpipe dump is showing the current connection table only.)

    How does the pool statistics page look like? 
    tmsh show ltm pool  members

    Thanks, Stephan

    Hi Sohail,

    your are right "
    tmsh
    " was introduced with TMOS v10 and "
    bigpipe
    " is the TMOS v9 equivalent.

    Based on the provided statistics data I see a relatively even distribution of traffic across all pool members in "
    session enabled
    " state.

    Pool members in state "
    session disabled
    " will not receive new connections (except for new connections matching persistence table entries [which is not the case in your setup as you wrote]).

    Make sure to set all pool members to "
    enabled
    " state via the WebUI configuration utility or via "bigpipe" command (can´t tell the syntax out of my head, sorry).

    Thanks, Stephan
