Observation

The rendering of a Service Graph Template is dependent on the following:

  • existence of two EPGs with a contract relationship,

As soon as that contract is attached to the Service Graph Template during the “Apply Service Graph Template” phase, then that is the moment where the Service Graph Instance appears in the APIC GUI.
