Configuring Cisco TrustSec SXP
To configure the SXP peer connection, perform this task:
Detailed Steps for Catalyst 6500
This example shows how to enable SXP and configure the SXP peer connection on Switch A, a speaker,
for connection to Switch B, a listener:
Router# configure terminal
Router(config)# cts sxp enable
Router(config)# cts sxp default password Cisco123
Router(config)# cts sxp default source-ip 10.10.1.1
Router(config)# cts sxp connection peer 10.20.2.2 password default mode local speaker
This example shows how to configure the SXP peer connection on Switch B, a listener, for connection
to Switch A, a speaker:
Router# configure terminal
Router(config)# cts sxp enable
Router(config)# cts sxp default password Cisco123
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# cts sxp connection
peer peer-ipv4-addr
[source src-ipv4-addr]
password {default | none] mode {local |
peer} {speaker | listener}
[vrf vrf-name]
Configures the SXP address connection.
The optional source keyword specifies the IPv4
address of the source device. If no address is specified,
the connection will use the default source address, if
configured, or the address of the port.
The password keyword specifies the password that
SXP will use for the connection using the following
options:
• default—Use the default SXP password you
configured using the cts sxp default password
command.
• none—Do not use a password.
The mode keyword specifies the role of the remote
peer device:
• local—The specified mode refers to the local
device.
• peer—The specified mode refers to the peer
device.
• speaker—Default. Specifies that the device is the
speaker in the connection.
• listener—Specifies that the device is the listener
in the connection.
The optional vrf keyword specifies the VRF to the
peer. The default is the default VRF.
Step 3
Router(config)# exit
Exits configuration mode.
Step 4
Router# show cts sxp connections
(Optional) Displays the SXP connection information.

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.
