Determining Your Software Release
To determine the version of Cisco IOS software running on your Cisco 1700 series router, log in to the platform and enter the show version EXEC command:
Cisco Internetwork Operating System Software
IOS (tm) 12.1 XT Software (c1700-y-mz), Version 12.1(3)XT1, RELEASE SOFTWARE
Upgrading to a New Software Release
For general information about upgrading to a new software release, see Software Installation and Upgrade Procedures located at: http://www.cisco.com/warp/public/130/upgrade_index.shtml.
Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features. Release 12.1(3)XT2 supports the same feature sets as Releases 12.1 and 12.1 T, but Release 12.1(3)XT2 can include new features supported by the Cisco 1700 series routers.
Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
Table 2 through Table 5 list the features and feature sets supported by the Cisco 1700 series routers in Cisco IOS Release 12.1(3)XT2. The tables use the following conventions:
•Yes—The feature is supported in the software image.
•No—The feature is not supported in the software image.
•In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, (2) means a feature was introduced in 12.1(2)T. If a cell in this column is empty, the feature was included in the initial base release.
Note These tables might not be cumulative or list all the features in each image. You can find the most current Cisco IOS documentation on CCO. These electronic documents may contain updates and modifications made after the hardcopy documents were printed.

New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 1700 series routers for Release 12.1(3)XT2.
New Hardware Features in Release 12.1(3)XT
The following new hardware feature is supported by the Cisco 1700 series routers for Cisco IOS Release 12.1(3)XT:
1-Port 10Base-T Ethernet WAN Interface Card
The 10Base-T Ethernet WAN Interface Card is a 1-port WAN interface card for the Cisco 1700 series of modular access routers. It provides the Cisco 1700 series routers with an optional second Ethernet interface for small and branch office customers deploying a second perimeter local area network (LAN) for public access or to connect a cable/DSL modem for broadband access. It connects to the Cisco 1700 series router platform through a WAN interface card slot, and to a line-side twisted pair connection through an RJ-45 connector.
For configuration instructions, refer to the document Configuring a Single-Port Ethernet WIC on a Cisco 1700 Series Router.
Important Notes
The following sections contain important notes that can apply to the Cisco 1700 series routers.
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software causes a Cisco router or switch to halt and reload if the IOS HTTP service is enabled and you browse to http://router-ip/anytext?/ and enter the enable password when it is requested. This defect can be exploited to produce a denial of service (DoS) attack. This vulnerability can only be exploited if the enable password is known or not set.
The vulnerability, identified as Cisco bug ID 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 IOS releases. Cisco urges all customers to upgrade to releases that are not vulnerable to this defect as listed in the complete advisory, which is available at: http://www.cisco.com/warp/public/707/ ioshttpserverquery-pub.shtml. You are strongly encouraged to read the complete advisory.
Cisco Express Forwarding
When installed in a Cisco 1720 or 1750 router, the Cisco Virtual Private Network (VPN) module does not support Cisco express forwarding (CEF).
Fan Operation in Cisco 1700 Series Routers
The fans in Cisco 1700 series routers stay off until thermally activated.
Flash defaults to Flash:1 on Multipartition Flash
When using a multipartition flash card, the various flash partitions are referred to as "flash:1:", "flash:2:", etc. If you specify only "flash" in a multipartition flash, the parser assumes "flash:1:." For example, if you enter show flash all, the parser defaults to "show flash:1: all" and only the flash information for the first partition displays. To see information for all flash partitions, enter show flash ?. This will list all of the valid partitions. Then enter show flash:xx: all on each valid partition.
Peak Cell Rate and Sustainable Cell Rate Values
On Cisco 1700 routers, specify the Peak Cell Rate (PCR) and Sustainable Cell Rate (SCR) as multiples of 32 Kbps. Other rates are treated as the next lower value of a multiple of 32. For example, an entered PCR value of 150 is considered 128.
Using the boot flash Command
Booting a Cisco 1700 series router with the commands boot flash or boot system flash results in unpredictable behavior. To work around this problem, be sure to enter a colon (:) following both commands (for example, boot flash: or boot system flash:.)
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.
All caveats in Cisco IOS Release 12.1 and Cisco IOS Release 12.1 T are also in Cisco IOS Release 12.1(3)XT1.
For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1.
For information on caveats in Cisco IOS Release 12.1 T, see Caveats for Cisco IOS Release 12.1 T, which lists severity 1 and 2 caveats and is located on CCO and the Documentation CD-ROM.
Note If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. To reach Bug Navigator II, Login to CCO and click Software Center: Cisco IOS Software: Cisco Bugtool Navigator II. Another option is to go directly to http://www.cisco.com/support/bugtools.
