Hello,

 

Please check the below points:

  1. Check that both GTM and LTM are having same big3d.
  2. Check iqdump command output from the GTMs to the LTM.
  3. make sure communication is going through the Self IP and not the management of any BIG-IP device.
  4. the autodiscover feature is disabled if NAT is activated on the LTM, so check whether NAT enabled or not, and if yes, unfurtunately, you will need to make it manually.

 

Thanks,

    Idump command shows configuration details from LTM but GTM under server list doesn't show it.

      Hello,

      Are the virtual server configured on the LTMs configured in non default route domain? if yes, you need to check "expose route domain options" when you are trying to discover the virtual servers.

      Hello,

       

      Are the LTM certificates the default self signed ceritificates or signed from a CA? if they are signed, you need to import the CA certificates. Also, make sure to run the big-ip scripts on GMTs and LTM as well.
