Hello,
I was reading about ACI fabric discovery process and want to make clear demarcation between IFM and OpFlex operations.
From book i read: "In this discovery process, a fabric node is considered active when the APIC and node can exchange heartbeats through the Intra-Fabric Messaging (IFM) process. The IFM process is also used by the APIC to push policy to the fabric leaf nodes."
I just want to understand if IFM is part of OpFlex ? or it is totally different protocol ? IFM operates only during switch discovery or heartbeats are constantly send ?
Thanks in advance,
