    Thank you very much for your help. We find the solution and the real problem. We have this configuration GTM 1, GTM 2 and GTM 3. All our GTM are synchronized.

     

    We have tested connection between GTM 1 and LTM, it's ok.

     

    We have tested connection between GTM 2 and LTM, it's ok.

     

    We have tested connection between GTM 3 and LTM, it doen't work.

     

    That's the problem.

     

    If One of your GTM group doesn't reach a LTM. All other GTM doesn't work. We have open port onfirewall for GTM 3 and now all it is ok.

     

    Thanks for all.

     

    Have a good day.

Hello Jonathan,

 

Does iquery works fine between GTM and LTM ? Also under the data centre server list when you configure your LTM, have you selected the health monitor as bigip ?

 

Please can you explain how you have configured your GTM and LTM ? a quick overview will be helpful.

 

Thanks, Pankaj

    Hello Pankaj,

     

    Thanks for your quick answer. Yes, we configure big ip has health monitor. To verify iquery we use the command : "iqdump LTM_IP" from GTM and it works fine.

     

    LTM virtual server Discovery works great on an other GTM. So we think ther is a problem on GTM But what ?

     

    I thought if iqdump work then virtual server Discovery work.

     

    We have our GTM in a network and our LTM in another network, tlnet 4353 and iqdump work fine. Thanks.
