New and Changed Information
The following sections list the new hardware and software features supported by the Cisco AS5200 for Cisco IOS Release 11.2 P.
New Hardware and Software Features in Cisco IOS Release 11.2(26) P
There are no new hardware and software features supported by the Cisco AS5200 for Cisco IOS Release 11.2(26) P.
New Software Features in Cisco IOS Release 11.2(11) P through 11.2(24) P
There are no new software features supported by the Cisco AS5200 for Cisco IOS Release 11.2(11) P through Cisco IOS Release 11.2(24) P, with the exception of the following:
Bundled Modem Code for the Cisco AS5200
Bundled modem code version 3.3.20 was provided in Cisco IOS Releases 11.2(15) P and 11.2(16) P.
New Software Features in Cisco IOS Release 11.2(10) P
Modem Pooling for the Cisco AS5200
Modem pooling allows service providers to define, select, and use separate pools of modems within a single access server or router to provide different dial-in services. Modem allocation is based on the dialed number identification service (DNIS) and a predetermined number of modem ports based on DNIS.
There are a number of applications for using the call setup information, including DNIS/ANI, processing incoming call requests with CallerID, and selecting services to set up "automatically" for specified calls. These uses generally fall into two categories: those requiring allocation of a specific number of modems for a specific service, and those requiring allocation of specific physical modems.
Note
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
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
Bundled Modem Code for the Cisco AS5200
For 56K modems, bundled modem code version 3.1.30 was provided. The modem code filename is:
mcom-modem-code-3.1.30.bin
New Software Features in Cisco IOS Release 11.2(6) P through 11.2(9) P
There are no new software features supported by the Cisco AS5200 in Cisco IOS Release 11.2(6) P though Release 11.2(9) P.
New Software Features in Cisco IOS Release 11.2(5) P
The following new feature is supported by the Cisco AS5200 only and are available in Cisco IOS Release 11.2(5) P and later.
Channelized E1 Signaling for the Cisco AS5200
Cisco IOS Release 11.2(5) P and later support channel-associated signaling for channelized E1 lines, which are commonly deployed in networks in Latin America, Asia, and Europe.
After this feature is configured on a single E1 controller, up to 30 remote users can simultaneously dial in to the Cisco AS5200 through networks running the R2 protocol. Typically, all 30 channels of a channelized E1 line are used for analog calls. However, a signal converter is still needed to perform conversions between R2 signaling and ear and mouth signaling (also known as E&M). Because the Cisco AS5200 has two physical E1 ports on its dual E1 Primary Rate Interface (PRI) board, up to 60 simultaneous connections can be made through the dual E1 PRI board.
These service adapters provide high-performance, hardware-based data compression capabilities via simultaneous stacker compression data compression algorithms with independent full-duplex compression and decompression capabilities on Point-to-Point Protocol (PPP) encapsulated packets.
Note
New Software Features in Cisco IOS Release 11.2(3) P through 11.2(4) P
There are no new software features supported by the Cisco AS5200 in Cisco IOS Release 11.2(3) P through Release 11.2(4) P.
New Features in Cisco IOS Release 11.2(1) P through 11.2(2) P
The following new features are supported by the Cisco AS5200 only and are available in Cisco IOS Release 11.2(1) P and later.
Robbed-Bit Signaling for the Cisco AS5200
Ground-start and loop-start signaling was provided for channelized T1. This new signaling is set using the cas-group controller configuration command.
For step-by-step software configuration information, refer to the feature module Channelized E1 Signaling for the Cisco AS5200, which is published in the Feature Guide for Cisco IOS Release 11.2 P. For instructions on how to reach this publication via Cisco.com or the Documentation CD-ROM, refer to the "Related Documentation" section.
Dual E1 PRI for the Cisco AS5200
A new E1 PRI card providing physical termination for two E1 PRI lines was introduced. Unlike most controller E1 configurations, the Cisco AS5200's E1 PRI controllers require a clock source, which is set with the clock source command.
Note
Important Notes
The following sections contain important notes about Cisco IOS Release 11.2 P that can apply to the Cisco AS5200.
Deferral of Cisco IOS Release 11.2(26)P1, 11.2(26)P2 and 11.2(26)P3 Images
All images in Cisco IOS Release 11.2(26)P1, 11.2(26)P2 and 11.2(26)P3 have been deferred due to the following severe defect:
CSCdw78210-Related to fixes in CSCdw65903 and outlined in
http://www.cisco.com/warp/public/707/cisco-malformed-snmp-msgs-pub.shtml.
These releases have been replaced with the following software solution, which is available on CCO:11.2(26)P4.
In order to increase network availability, Cisco recommends that you upgrade affected IOS images with the suggested replacement software images. Cisco will discontinue manufacturing shipment of affected IOS images. Any pending order will be substituted by the replacement software images.
Note
The terms and conditions that governed your rights and obligations and those of Cisco, with respect to the deferred images will apply to the replacement images.
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable password is supplied when requested. This defect can be exploited to produce a denial of service (DoS) attack.
The vulnerability, identified as Cisco caveat CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected Cisco IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml.
