Q

What is the key difference between a traditional SDN control plane and Ciscos APIC?

A

Cisco keeps the control plane on the device but uses a stateless controller in its SDN to send policy changes to network devices. The individual network device is responsible for translating the policies into commands.

Q

What is the key difference between a traditional SDN control plane and Ciscos APIC-EM

A

Uses traditional methods such as Telnet, SSH, and SNMP to the control plane on devices that do not have a native API environment.
