Chapter 5 Configuring SGACL Policies
Enabling SGACL Policy Enforcement Per Interface
Enabling SGACL Policy Enforcement Per Interface
You must first enable SGACL policy enforcement globally for Cisco TrustSec-enabled routed interfaces.
This feature is not supported on Port Channel interfaces.
To enable SGACL policy enforcement on Layer 3 interfaces, perform this task:
Detailed Steps Catalyst 6500
Configuration Examples for Enabling SGACL Policy Enforcement Per Interface
Catalyst 3850:
Switch# configure terminal
Switch(config)# interface gigabit 1/0/2
Switch(config-if)# cts role-based enforcement
Switch(config-if)# end
Enabling SGACL Policy Enforcement on VLANs
You must enable SGACL policy enforcement on specific VLANs to apply access control to switched
traffic within a VLAN, or to traffic that is forwarded to an SVI associated with a VLAN.
To enable SGACL policy enforcement on a VLAN or a VLAN list, perform this task:
Detailed Steps Catalyst 6500
Configuration Examples for Enabling SGACL Policy Enforcement on VLANs
Catalyst 3850:
Switch# configure terminal
Switch(config)# cts role-based enforcement vlan-list 31-35,41
Switch(config)# exit
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# interface gigabit 6/2
Specifies interface on which to enable or
disable SGACL enforcement.
Step 3
Router(config-if)# cts role-based enforcement
Enables Cisco TrustSec SGACL policy
enforcement on routed interfaces.
Step 4
Router(config-if)# do show cts interface
Verifies that SGACL enforcement is enabled.
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# cts role-based
enforcement vlan-list vlan-list
Enables Cisco TrustSec SGACL policy enforcement
on the VLAN or VLAN list.

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.
