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 Cisco IOS 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 page 14.

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-configstartup-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.
