78-5214-15 Rev. A0
Introduction
Introduction
The Cisco AS5200 universal access server is a multifaceted data communications platform that provides
all the functions of an access server, a router, modems, and terminal adapters (TAs) in a modular chassis.
Mid-sized organizations or service providers requiring centralized processing capabilities for mobile
users and telecommuters will benefit the most using the Cisco AS5200 universal access server.
With its optimization for high-speed modem access, the Cisco AS5200 universal access server is ideally
suited for all traditional dial-up applications, such as host access, electronic mail, file transfer, and
dial-in access to a local area network.
For information on new features and Cisco IOS commands supported by Cisco IOS Release 11.2(26) P,

New and Changed Information
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 For step-by-step software configuration information, refer to the online feature module Modem
Pooling for the Cisco AS5200, which is part of the online publication 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 on page 14.
12. TACACS+ Single Connection and TACACS+ SENDAUTH enhancements are supported.
13. Cisco IOS Release 11.2 introduces several DLSw+ enhancements available in the Plus, Plus 40, and Plus 56 feature sets.
14. SRB/RSRB is fast switched. This enhancement is on by default, but can be disabled.
15. Terminal services are supported on access servers (with limited support on router auxiliary ports).
16. Use of LAT requires terminal license (FR-L8-10.X= for an 8-user license or FR-L16-10.X= for a 16-user license).

Release Notes for Cisco AS5200 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 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-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. The modem code filename is:
mcom-modem-code-3.1.30.bin

Release Notes for Cisco AS5200 Universal Access Servers for Cisco IOS Release 11.2 P
78-5214-15 Rev. A0
New and Changed Information
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 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 on page 14.
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.

Important Notes
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 on page 14.
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 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,

Caveats
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.
Some 40-bit Encryption Images Are Unavailable
Cisco is conducting an internal review of the build and distribution processes associated with its 40-bit
Cisco IOS cryptographic products. To provide seamless access to Cisco IOS 40-bit encryption capability,
Cisco will provide access to the most current 40-bit encryption images, beginning with Cisco IOS
Release 11.2 (12), 11.2(12)P, and 11.3(2). The following 40-bit encryption images will be indefinitely
unavailable:
•11.2(1)–11.2(11.2)
•11.2(2)P–11.2(11.1)P
•11.2(1)F–11.2(4)F
•11.3(1)
This review is not related to any new or previously unreported bugs. The information gathered in the
review will be used to implement new automated development and order processing applications.
Some V.110 Terminal Adapters are Unavailable
The V.110 terminal adapters are not supported in Cisco IOS Release 11.2(12) P through 11.2(15) P.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most
serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only
select severity 3 caveats are included in the caveats document.
This section only contains open and resolved caveats for the current Cisco IOS maintenance release.
