Manually Configuring a Device SGT
In normal Cisco TrustSec operation, the authentication server assigns an SGT to the device for packets
originating from the device. You can manually configure an SGT to be used if the authentication server
is not accessible, but an authentication server-assigned SGT will take precedence over a
manually-assigned SGT.
To manually configure an SGT on the device, perform this task:
Detailed Steps for Catalyst 6500, 3850, 3750-X
Configuration Examples for Manually Configuring a Device SGT
Catalyst 6500, Catalyst 3850, and Catalyst 3750-X:
Switch# configure terminal
Switch(config)# cts sgt 1234
Switch(config)# exit
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# cts sgt tag
Configures the SGT for packets sent from the device.
The tag argument is in decimal format. The range is 1
to 65533.
Step 3
Switch(config)# exit
Exits configuration mode.

Cisco TrustSec Specifications

General

Category	Network Security
Functionality	Provides role-based access control, network segmentation, and policy enforcement.
Key Components	Security Group Tags (SGT), Security Exchange Protocol (SXP).
Authentication Methods	802.1X, MAC Authentication Bypass (MAB), Web Authentication
Security Group Tagging (SGT)	Assigns security group tags to users and devices for identity-based segmentation.
Security Exchange Protocol (SXP)	A protocol used to propagate SGT information across network devices.
Policy Enforcement	Enforces security policies based on SGTs and SGACLs.
Benefits	Enhanced security, simplified policy management, and improved compliance.
Encryption	Supports encryption for data in transit through IPsec and MACsec.
Scalability	Scalable to large enterprise networks with thousands of devices.
Compatibility	Compatible with a wide range of Cisco network devices.
Description	Cisco TrustSec is a security architecture framework designed to build secure networks. It uses identity-based access control to segment the network and enforce policies based on user roles and device types, rather than relying solely on IP addresses.
