Cisco DFA Services Support
Services such as a firewall, load balancer, and virtual private networks (VPNs) are deployed at the aggregation
layer in the traditional data center. In a Cisco Dynamic Fabric Automation (DFA) deployment, services nodes
are deployed at regular leaf switches for both east-west and north-south traffic. Services can be physical or
virtual services nodes.
The following figure shows the interaction between the Cisco Prime Network Services Controller (NSC) and
the Cisco DFA deployment through Cisco Data Center Network Manager (DCNM).
