What protocols does APIC use to push policies and objects to switches and vCenter?

Is APIC using HTTPS/SSL or some other protocol to push out configuration to switches and vcenter? Is it based on TCP or UDP?

Hello,

Protocols used are as follows:

1.Between APIC and ACI switches: Opflex protocol

2. Between APIC and Vcenter: HTTPS(if I am not wrong they communicate via APIs)

For more details on Opflex kindly refer below link:

Hope that helps!
