Version 4.1 - 6.5 Network segregation
There's not a lot to network segregation (or more accurately segmentation) that would be beyond any network engineer. Before moving on to the subtopics, you should probably take a look at Cisco TrustSec for Policy-Defined Segmentation.
And you should probably take a look at Cisco Nexus 1000v Network Segmentation Manager Configuration Guide - just to be thorough.
Step 1 Enable the NSM feature using the "Enabling the NSM Feature" section.
Step 2 Create a port profile for network segmentation policies using the "Creating a Port Profile for Network Segmentation Policies" section.
Step 3 Create network segmentation policies using the "Creating Network Segmentation Policies" section.
Step 4 Register NSM with vShield Manager using the "Registering vShield Manager with Network Segmentation Manager" section.
