Automatically Configuring a New or Replacement Password
with the Authentication Server
As an alternative to manually configuring the password between the switch and the authentication server,
you can initiate a password negotiation from the switch. To configure the password negotiation, perform
this task:
Detailed Steps for Catalyst 6500
Command Purpose
Step 1
Router# cts change-password server
ip-address port {key secret | a-id a-id}
Initiates a password negotiation between the switch
and the authentication server.
• ip-address—The IP address of the authentication
server.
• port—The UDP port of the authentication server.
• key secret—The RADIUS shared secret of the
authentication server.
• a-id a-id—The A-ID associated with the
authentication server.

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.
