Classis STP Limitation 50% of all Links not utilized Complex to Harden
No STP Blocked Ports Full Links Utilization Faster Convergence Macro for “best practice”
No STP Simple to Configure Higher Fabric Bandwidth Consistent Latency
Spine Scales to provide fabric bandwidth
Leaf Scales to provide access port density
Workload Mobility Increased App Communication Higher Server Port Density and Bandwidth

Programmable Fabric Attributes Rapid Deployment of VM and Network
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
