Security Group Access – Security Group Tagging

Cisco Proprietary

Tags are added after the 802.1Q information in the Ethernet frame.

Network Access Device will tag the L2 packets from the endpoint based on the ISE authorization policy. The tags will be used in Security Group ACLs around the network to allow or block access to the resources.

• Classification: at ingress, dynamic (802.1x, MAB, Web Authentication) or static (based on IP, subnet, VLAN)
• Transport: SGT is propagated via inline tagging or SXP
• Enforcement: Policy is applied via SGACL or SGFW
