Catalyst 3750-X and 3560-X Switch Software Configuration Guide
OL-21521-01
Chapter 1 Overview
Features
–
IP phone detection enhancement to detect and recognize a Cisco IP phone
–
Guest VLAN to provide limited services to non-IEEE 802.1x-compliant users
–
Restricted VLAN to provide limited services to users who are IEEE 802.1x compliant, but do
not have the credentials to authenticate via the standard IEEE 802.1x processes
–
IEEE 802.1x accounting to track network usage
–
IEEE 802.1x with wake-on-LAN to allow dormant PCs to be powered on based on the receipt
of a specific Ethernet frame
–
Voice aware IEEE 802.1x security to apply traffic violation actions only on the VLAN on which
a security violation occurs
–
Network Edge Access Topology (NEAT) with 802.1x switch supplicant, host authorization with
CISP, and auto enablement to authenticate a switch outside a wiring closet as a supplicant to
another switch.
–
IEEE 802.1x authentication with downloadable ACLs and redirect URLs to allow per-user ACL
downloads from a Cisco Secure ACS server to an authenticated switch.
–
Multiple-user authentication to allow more than one host to authenticate on an 802.1x-enabled
port.
• MAC authentication bypass to authorize clients based on the client MAC address.
• Voice aware IEEE 802.1x and mac authentication bypass (MAB) security violation to shut down
only the data VLAN on a port when a security violation occurs
• Network Admission Control (NAC) features:
–
NAC Layer 2 IEEE 802.1x validation of the antivirus condition or posture of endpoint systems
or clients before granting the devices network access.
For information about configuring NAC L
ayer 2 IEEE 802.1x validation, see the “Configuring
NAC Layer 2 IEEE 802.1x Validation” section on page 11-58.
–
NAC Layer 2 IP validation of the posture of endpoint systems or clients before granting the
devices network access.
For information about configuring NAC Layer 2 IP validation, see the Network Admi
ssion
Control Software Configuration Guide.
–
IEEE 802.1x inaccessible authentication bypass.
For information about configuring this feature, see the “
Configuring the Inaccessible
Authentication Bypass Feature” section on page 11-53.
–
Authentication, authorization, and accounting (AAA) down policy for a NAC Layer 2 IP
validation of a host if the AAA server is not available when the posture validation occurs.
For information about this feature, see the Network Adm
ission Control Software Configuration
Guide.
• TACACS+, a proprietary feature for managing network security through a TACACS server
• RADIUS for verifying the identity of, granting access to, and tracking the actions of remote users
through AAA services
• Kerberos security system to authenticate requests for network resources by using a trusted third
party
• Secure Socket Layer (SSL) Version 3.0 support for the HTTP 1.1 server authentication, encryption,
and message integrity and HTTP client authentication to allow secure HTTP communications
