IOS (tm) c1700 Software (c1700-y-mz), Release 12.2(2)XQ, 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 12.2(2)XQ supports the same feature sets as Releases 12.2 and 12.2 T, but Release 12.2(2)XQ 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 can 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 (Parts 1 through 4) lists the features and feature sets supported by the Cisco 1700 series routers in Cisco IOS Release 12.2(2)XQ. The table uses 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 shows the Cisco IOS release in which the feature was introduced. For example, (12.2[2]XQ) means a feature was introduced in Release 12.2(2)XQ. If a cell in this column is empty, the feature was included in the initial 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 Cisco.com. These electronic documents may contain updates and modifications made after the hardcopy documents were printed.

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2(2)XQ that can apply to the Cisco 1700 series. (Also, see the "Caveats" section.)

Cisco Express Forwarding

When installed in a Cisco 1720, 1750, or 1751 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 or defects 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 Release 12.2 T are also in Release 12.2(2)XQ. For information on caveats in Cisco IOS Release 12.2 T, refer to the Caveats for Cisco IOS Release 12.2 T document. For information on caveats in Cisco IOS Release 12.2, refer to the Caveats for Cisco IOS Release 12.2 document. These documents list severity 1 and 2 caveats, and are 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. You can reach Bug Navigator II on CCO at Software Center: Cisco IOS Software: BUG TOOLKIT: Cisco Bug Navigator II, or at http://www.cisco.com/support/bugtools/bugtool.shtml. 

---

Caveats for Release 12.2(2)XQ

This section describes possibly unexpected behavior by Release 12.2(2)XQ. Only severity 1 through 3 caveats are included.

CSCdu07336

The number of packets matched is incorrect when the length of the IP packet is greater than the MTU, as shown by the command show policy int atm slot/port.

CSCdu38029

The call completion rate of LLQ+LFI through virtual-template is less than ninety-eight percent.
