Hi Stephan:

 

Thanks for relay.

 

current Ver big3d running 11.2.1 and 11.5.2.

 

11.2.1 big3d GTM able to discover VS with LTM 11.2.1 and 11.5.2 big3d. 11.5.2 big3d GTM failed discovery both version.

 

we are planning to update current all 11.2.1 GTM to 11.5.2. that why we have 2 version LTM and 2 version GTM connected together. So we try to ensure we resolve this issue in LAB before upgrade the production GTM.

 

is there other way to resolve this issue?

 

Thanks Danny

Hi Danny, I will rebuild my virtual lab tomorrow and cross check before recommending to use the big3d_install script to run a update on the big3d agent on the v11.2.1 platforms. Will keep you posted. Thanks, Stephan
