Introduction
The Cisco 3600 series includes the Cisco 3620 and Cisco 3640 routers. As modular solutions, the Cisco 3620 and Cisco 3640 enable corporations to increase dial-up intensity and take advantage of current and emerging wide-area network (WAN) technologies and networking capabilities. The Cisco 3600 series routers are fully supported by Cisco IOS software, which includes dial-up connectivity, LAN-to-LAN routing, data and access security, WAN optimization, and multimedia features.
For information on new features and Cisco IOS commands supported by Cisco IOS Release 11.2 P, see the "New and Changed Information" section and the "Related Documentation" section.

New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 3600 series for Cisco IOS Release 11.2 P.
New Features in Cisco IOS Releases 11.2(13)P through 11.2(26)P
No new features are supported by the Cisco 3600 series for Cisco IOS Release 11.2(13) and later P-train releases.
New Hardware Feature in Cisco IOS Release 11.2(12)P
The following new hardware feature is supported by the Cisco 3600 series in Cisco IOS Release 11.2(12)P and later releases.
T1 CSU WIC
The Cisco T1 data service unit/channel service unit (CSU) WAN interface card is an integrated, managed, T1 or fractional T1 WAN interface card. It provides nonchannelized data rates of 1 to 24 times 64 kilobits per second (kbps) or 1 to 24 times 56 kbps and follows ANSI T1.403 and AT&T Publication 62411 standards.
The Cisco T1 CSU WIC interface includes the following management features:
•
•
•
•
•
•
New Features in Cisco IOS Release 11.2(11)P
No new features are supported by the Cisco 3600 series for Cisco IOS Release 11.2(11)P.
New Hardware Feature in Cisco IOS Release 11.2(10)P
The following new hardware feature is supported by the Cisco 3600 series in Cisco IOS Release 11.2(10)P and later releases.
Digital Modem Network Modules
Digital modem network modules for the Cisco 3640 modular routers are supported in Cisco IOS Release 11.2(10)P and later releases. These modules are available in 6-, 12-, 18-, 24-, and 30-port sizes. Cisco 3620 routers support these modules in Cisco IOS Release 11.3(4)T1 and later releases.
These modules contain 6, 12, 18, 24, or 30 V.34+ digital modems for a direct digital connection to an Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) channel, allowing you to mix digital and analog calls to provide remote access to a LAN.
Digital modem network modules do not provide network interfaces of their own, but instead handle analog calls passing through other router interfaces. In addition to the digital modem module, the router must contain a PRI network module to connect to the ISDN channel, and another module, such as Ethernet, to provide connectivity to the LAN. The PRI module concurrently handles digital ISDN data connections and remote voice-channel (analog) modem connections, allowing a dynamic mix of digital and modem connections. The digital modem module acts as a pool of available modems that can be used for both incoming and outgoing calls.
Note
The following digital modem network module features are not supported in Cisco IOS Release 11.2(10)P for the Cisco 3640:
•
•
•
•
•
The following Cisco IOS commands, which apply to modem functionality, are not supported by the modem modules:
•
•
•
•
•
•
•
•

New Software Feature in Cisco IOS Release 11.2(10)P
The following new software enhancement is supported by the Cisco 3600 series in Cisco IOS Release 11.2(10)P and later releases.
Web Cache Control Protocol
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 travel only 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 benefit from web proxy caches without having to configure clients to contact a specific proxy server in order to access web resources. Many web proxy caches require clients to access 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. Routers running Cisco IOS software intelligently intercept HTTP requests and transparently redirect them to a Cisco Cache Engine.
Note
New Features in Cisco IOS Releases 11.2(8)P and 11.2(9)P
No new features are supported by the Cisco 3600 series for Cisco IOS Releases 11.2(8)P and11.2(9)P.
New Hardware Features in Cisco IOS Release 11.2(7)P
The following new hardware features are supported by the Cisco 3600 series in Cisco IOS Release 11.2(7)P and later releases.
Asynchronous Serial Task List
The 16- and 32-port asynchronous network module is supported in Cisco IOS Release 11.2(7)P and later releases. When used with corresponding octal cables, these modules provide 16 or 32 EIA/TIA-232 data terminal equipment (DTE) serial interfaces. Speeds up to 134.4 kbps are supported.
Note
Compression Network Module
The compression network module is supported Cisco IOS Release 11.2(7)P and later releases. This module provides hardware assistance to protocols that use compression and decompression, reducing the load on the CPU caused by software compression, while improving router performance.
The compression network module does not provide network interfaces of its own, but instead compresses and decompresses data passing through interfaces on other network modules or WAN interface cards in the router. The following interfaces are supported:
•
•
•
•
•
Hardware compression is supported only over Point-to-Point Protocol (PPP) links. The compression network module supports only the stacker compression algorithm.
Note
New Hardware Feature in Cisco IOS Release 11.2(6)P
The following new hardware feature is supported by the Cisco 3600 series in Cisco IOS Release 11.2(6)P and later releases.
Fast Ethernet Network Module
The Fast Ethernet network module provides a single interface that supports 100BaseT and 10BaseT connectivity. There is one RJ-45 10/100 port on the Fast Ethernet network module. This port enables autonegotiation of the peers' capabilities and configures itself to support the highest possible data rate.
Note
New Software Features in Cisco IOS Release 11.2(5)P
The following new software features are supported by the Cisco 3600 series in Cisco IOS Release 11.2(5)P and later releases.
Modular Design of Cisco 3600 Series Routers

Important Notes
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.
Product Number Change
Beginning with Cisco IOS Release 12.0(7) XK, Cisco changed the product numbers you use to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maintenance release, and build number. The following table provides some examples.
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.
For information on caveats in Cisco IOS Release 11.2 P, refer to the Caveats for Cisco IOS Release 11.2 P located on Cisco.com and the Documentation CD-ROM.
All caveats in Cisco IOS Release 11.2 are also in Cisco IOS Release 11.2 P.
For information on caveats in Cisco IOS Release 11.2, refer to the "Caveats" section in the Cross-Platform Release Notes for Cisco IOS Release 11.2 on Cisco.com and the Documentation CD-ROM. These release notes list severity 1 and 2 caveats affecting all maintenance releases.
Note
