Appendix C Notes for Catalyst 6500 Series Switches
FIPS Support
Prerequisites for FIPS Configuration
• Disable Telnet. Users should log in using Secure Shell (SSH) only.
• Disable SNMPv1 and v2. Any existing user accounts on the device that have been configured for
SNMPv3 should be configured only with SHA for authentication and AES/3DES for privacy.
• Delete all SSH server RSA1 key-pairs.
Guidelines and Limitations for FIPS
• The RADIUS keywrap feature works only with Cisco Identity Services Engine 1.1 or Cisco ACS
Release 5.2 or later releases.
• HTTPS/TLS access to the module is allowed in FIPS approved mode of operation, using
SSLv3.1/TLSv1.0 and a FIPS approved algorithm.
• SSH access to the module is allowed in FIPS approved mode of operation, using SSHv2 and a FIPS
approved algorithm. Many SSH clients provide cryptographic libraries that can be set to FIPS Mode,
making all cryptographic operations FIPS 140-2 Level 2 compliant.
• Your passwords must have a minimum of eight alphanumeric characters including at least one letter
and at least one number character.
Default Settings for FIPS
The default is FIPS mode disabled, RADIUS keywrap disabled.

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.
