1 Network Admin defines Network Profile Template for VMs/PMs in projects

2 Instances of Network Policies are automatically created in VTS (or DCNM) when a Server Admin provisions VMs/PMs

3 When a VM/PM pertaining to a project is detected, Network Policy is applied to the leaf

4 When VM moves, the Network Policy is applied automatically to the leaf

Cisco DCNM Prime Benefit

15

“Cisco Prime DCNM 7 helps simplify cloud operations and automate network configurations for lower Opex in next-generation fabrics”

Day 1 §  Helps lower opex with efficient management & visualization – includes overlay/underlay visibility

§  Integrated with Cisco UCS Director, VMware vCloud Director and OpenStack for Auto-configuration

Day 0 §  Ready-to-run, virtual appliance

§  Makes large fabrics easy to deploy

Contains the infrastructure necessary to install, maintain and grow your network fabric.

§  REST APIs for NMS/OSS Automation flexibility
