New Software Features in Release 12.3(2)XA
The following sections describe the new software features supported by the Cisco 1700 series routers for Release 12.3(2)XA.
Analog CAMA E911 Trunk
The Cisco 1751 and 1760 routers now support Analog Centralized Automatic Message Accounting (CAMA) trunks on the two- and four-port Foreign Exchange Office (FXO) cards. The VIC2-2FXO and VIC2-4FXO cards are now user configurable for CAMA mode operation on a port-by-port basis. For example, on the VIC2-2FXO card, the Port 0 can be configured for CAMA and port 1 can be configured for FXO-M1 operation.
The CAMA feature offers the following benefits:

VPN Access Control Using 802.1x Authentication
The 802.1x authentication feature is an Institute of Electrical and Electronics Engineers (IEEE) standards-based authentication technology. This feature enhances the Cisco IOS technology by supporting 802.1x authentication. It allows classification of users into authenticated and non-authenticated categories, based on the user credentials provided using the 802.1x port-based authentication specification. This feature also allows separate processing of traffic coming from authenticated users and non-authenticated users. Authenticated users are allowed to access a corporate IPSec tunnel. Unauthenticated or guest users are allowed to access local interconnections as well as connectivity to the Internet, but not a corporate IPSec tunnel.
In Cisco IOS Release 12.3(2)XA, the 802.1x user authentication support will be used in conjunction with Easy VPN Server and Easy VPN Remote (also called Easy VPN Client [EZVPN Client]).
For details on Cisco Easy VPN, refer to the following URL:
http://www.cisco.com/en/US/partner/products/sw/secursw/ps5299/index.html

Step 3
Step 4
An alternative to Microsoft's 802.1x authentication client, AEGIS 802.1x software for Microsoft Windows, can be found at the following URL:
NAT - Static IP Support
Public WAN networks use dynamic IP address allocation, and expect their users to be able to be provided an IP Address dynamically using Dynamic Host Configuration Protocol (DHCP).
When a customer's IP address is statically configured, the users cannot connect to the Internet and/or their corporation's Virtual Private Network (VPN).
With the static IP enhancement, users whose IP address is statically configured will be provided an IP address dynamically and will be able to establish an IP session (with the Internet or other destination networks).
The Cisco IOS Network Address Translation (NAT) feature will detect the fact that the user is statically configured and will provide the user with a working IP address within the public WAN network allowing the user to establish an IP session.
Support for user configurable CAMA operation is on a port-by-port basis.
New Software Features in Release 12.3(2)T
For information regarding the features supported in the Cisco IOS Release 12.3(2)T, refer to the Cross-Platform Release Notes and New Feature Documentation links at the following location on Cisco.com:
