GTM LTM Virtual Discovery

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.
   • TAC said it is not possible to run it over the management interface.
   • https://community.f5.com/t5/technical-forum/gtm-not-discovering-ltm-virtual-server/td-p/261988
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,
