announces Cisco IOS
LRE, 2940, and 2955 Series Switches and CIGESM Blade Switch.
This product bulletin contains content and delivery information for Cisco IOS Software Release
12.1(22)EA9.
The following new features are available with Cisco IOS Software Release 12.1(22)EA9 for the
Cisco Catalyst 2940 Series:
IEEE 802.1x MAC-Authentication-Bypass: This feature allows clientless end users (with
●
no 802.1x supplicant) to authenticate to the network, utilizing the MAC address of the
device. The switch will initiate an Extensible Authentication Protocol (EAP) conversation
with an authentication, authorization, and accounting (AAA) server on behalf of a device to
authenticate the MAC address itself. This process is transparent to the end user and
utilizes a prepopulated database on the AAA server.
Table 1 lists new features of Cisco IOS Software Release 12.1(22)EA9.
