Product Bulletin No. 3012

Cisco Systems® announces Cisco IOS® Software updates for the Cisco® Catalyst® 3550, Catalyst 2950, Catalyst 2950 LRE, and Catalyst 2940 series and Cisco Catalyst 2955 Intelligent Ethernet switches.

OVERVIEW

This new release furthers Cisco leadership in providing secure, reliable, and feature-rich LAN switching solutions. This product bulletin contains content and delivery information for Cisco IOS Software Release 12.1(22)EA5.
The following new features are available with Cisco IOS Software Release 12.1(22):

NAC L2 802.1x-NAC L2 802.1x enables a switch to enforce network access privileges based on information such as the revision of anti-virus software or OS patch level running on the end station. This feature uses the 802.1X port authentication mechanism to allow an agent running on the end station to provide Network Admission Control (NAC) information to the AAA server along with the authentication credentials. The AAA server can direct the end station into an appropriate VLAN based on the NAC information.

Standard 802.1x with Wake on LAN Feature-This feature allows transmission of frames from an unauthenticated port to the connected end station, blocking only inbound traffic until authentication completes. Customers deploying IEEE 802.1x port authentication and also using remote desktop-management systems can use this feature to "wake up" PCs and perform maintenance, even if a user is not currently logged in or the PC is down.

Extended VLAN IDs-This feature extends the existing support for the full range of 4094 VLAN IDs to the Cisco Catalyst 2940 platform, which was restricted to using VLAN IDs in the range 1 to 1005.
