Ethernet SGT Protection

In a Cisco TrustSec network, a Cisco ISE assigns a Layer 2 Security Group Tag (SGT) to a user’s or endpoint’s session.
In a Cisco TrustSec network, a Cisco Identity Services Engine (ISE) assigns a Layer 2 Security Group Tag (SGT) of 16 bits to a user’s or endpoint’s session. You can create a Zone Protection profile with Ethernet SGT protection when your firewall is part of a Cisco TrustSec network. The firewall can inspect headers with 802.1Q (Ethertype 0x8909) for specific Layer 2 security group tag (SGT) values and drop the packet if the SGT matches the list you configure for the Zone Protection profile attached to the interface. Determine which SGT values you want to deny access to a zone.
