The video looks into Cisco TrustSec feature on Cisco Nexus 1000V. We will configure port-profiles to assign SGT to hosts, and have SGT-to-IP mapping sent to an ASA firewall over a SXP connection for policy enforcement. We will see how we can construct an ACL on the ASA to permit or deny traffic based on SGT value using a object-group-security. 

Notes:
  • As of version 4.2.1.SV2, Nexus 1000V
    • cannot enforce access policy with SGT (SGACL)
    • cannot insert SGT into packet
    • does not support dynamic SGT assignment from a policy server (eg. ISE)
  • Advanced license is required for Cisco TrustSec feature
