Chapter 5 Configuring SGACL Policies
Manually Configuring SGACL Policies
Manually Configuring SGACL Policies
A role-based access control list bound to a range of SGTs and DGTs forms an SGACL, a TrustSec policy
enforced on egress traffic. Configuration of SGACL policies are best done through the policy
management functions of the Cisco ISE or the Cisco Secure ACS. To manually (that is, locally)
configure SGACL policies, do the following:
1. Configure a role-based ACL.
2. Bind the role-based ACL to a range of SGTs.
Note An SGACL policy downloaded dynamically from the Cisco ISE or Cisco ACS overrides any conflicting
manually configured policy.
