Catalyst 3750-E and 3560-E Switch Software Configuration Guide
1-12
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
IEEE 802.1x readiness check to determine the readiness of connected end hosts before configuring
IEEE 802.1x on the switch
Support for IP source guard on static hosts
RADIUS Change of Authorization (CoA) to change the attributes of a certain session after it is
authenticated. When there is a change in policy for a user or user group in AAA, administrators can
send the RADIUS CoA packets from the AAA server, such as Cisco Secure ACS to reinitialize
authentication, and apply to the new policies
IEEE 802.1x User Distribution to allow deployments with multiple VLANs (for a group of users) to
improve scalability of the network by load balancing users across different VLANs. Authorized
users are assigned to the least populated VLAN in the group, assigned by RADIUS server
Support for critical VLAN with multiple-host authentication so that when a port is configured for
multi-auth, and an AAA server becomes unreachable, the port is placed in a critical VLAN in order
to still permit access to critical resources
Customizable web authentication enhancement to allow the creation of user-defined login, success,
failure and expire web pages for local web authentication
Support for Network Edge Access Topology (NEAT) to change the port host mode and to apply a
standard port configuration on the authenticator switch port
VLAN-ID based MAC authentication to use the combined VLAN and MAC address information for
user authentication to prevent network access from unauthorized VLANs
MAC move to allow hosts (including the hosts connected behind an IP phone) to move across ports
within the same switch without any restrictions to enable mobility. With MAC move, the switch
treats the reappearance of the same MAC address on another port in the same way as a completely
new MAC address
Support for 3DES and AES with version 3 of the Simple Network Management Protocol (SNMPv3).
This release adds support for the 168-bit Triple Data Encryption Standard (3DES) and the 128-bit,
192-bit, and 256-bit Advanced Encryption Standard (AES) encryption algorithms to SNMPv3
Support for the Security Group Tag (SCT) Exchange Protocol (SXP) component of Cisco TrustSec,
a security architecture using authentication, encryption, and access control
Automatic QoS (auto-QoS) to simplify the deployment of existing QoS features by classifying
traffic and configuring egress queues
Cross-stack QoS for configuring QoS features to all switches in a switch stack rather than on an
individual-switch basis (only Catalyst 3750-E switches)
Auto-QoS enhancements that add automatic configuration classification of traffic flow from video
devices, such as the Cisco Telepresence System and Cisco Surveillance Camera.
