Release Notes for CiscoAS5200 Universal Access Servers for Cisco IOS Release 11.2 P
78-5214-15 Rev. A0
New and Changed Information
Web Cache Control Protocol for the Cisco AS5200
The Web Cache Control Protocol (WCCP) feature allows you to use a Cisco Cache Engine to handle web
traffic, thus reducing transmission costs and downloading time. This traffic includes user requests to
view pages and graphics on World Wide Web servers, whether internal or external to your network, and
the replies to those requests.
Web caches reduce transmission costs and the amount of time required to download web files. If a client
requests a web page that is already cached, the request and data only have to travel between the Cisco
Cache Engine and the client. Without a web cache, the request and reply must travel over the Internet or
wide-area network.
Cisco IOS support of WCCP provides a transparent web cache solution. Users can benefit from web
proxy caches without having to configure clients to contact a specific proxy server in order to reach web
resources. Many web proxy caches require clients to reach web resources through a specific proxy web
server rather than using the originally requested web server URL. With WCCP, the clients send web
requests to the desired web server URL. Cisco IOS routers intelligently intercept HTTP requests and
transparently redirect them to a Cisco Cache Engine.
Note For step-by-step software configuration information, refer to the online feature module Web Cache
Control Protocol, which is part of the online publication CiscoIOS Release 11.2(10+)P New Feature
Documentation. For instructions on how to reach this publication via Cisco.com or the
Documentation CD-ROM, refer to the “Related Documentation” section on page14.
Flash Load Helper for the Cisco AS5200
This feature enables you to upgrade the system software on run-from-Flash memory systems that have
a single bank of Flash memory. It is a lower-cost software upgrade solution than dual-bank Flash
memory, which requires two banks of Flash memory on one SIMM.
Flash Load Helper is an automated procedure that reloads the ROM-based image, downloads the
software to Flash memory, and reboots to the system image in Flash memory. Flash Load Helper
performs checks and validations to maximize the success of a Flash memory upgrade and to minimize
the chance of leaving Flash memory either in an erased state or with a file that cannot boot.
Fastboot for the Cisco AS5200
This feature speeds up the boot process by using the system image directly from the system bootstrap
image without accessing the boot image. To enable this feature, perform a write memory by entering the
copy running-config startup-config command when running Cisco IOS Release 11.2(10) P or later.
Note If you run an image earlier than Cisco IOS Release 11.2(7) P or perform a write memory with
Cisco IOS Releases 11.2(7) P to 11.2(9) P, the feature will automatically disable itself.
Bundled Modem Code for the Cisco AS5200
For 56K modems, bundled modem code version 3.1.30 was provided. Themodem code filename is:
mcom-modem-code-3.1.30.bin
