Determining Your Software Release

To determine the version of Cisco IOS software currently running on your Cisco 1700 series router, log in to the router and enter the show version EXEC command. The following sample output from the show version command indicates the version number on the second output line:

router> show version
Cisco Internetwork Operating System Software 
IOS (tm) c1700 Software (c1700-y-mz), Version 12.2(4)XL6, 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 Sets

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(4)XL6 supports the same feature sets as Releases 12.2 and 12.2(4)T, but Release 12.2(4)XL6 includes new features supported by the Cisco 1700 series routers, including support for the command Squeeze Flash: and for G.SHDSL ATM WIC software on all the Release 12.2(4)XL6 images listed in the "Memory Requirements" section, in Table 1: "Recommended Memory for 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.

The command Squeeze Flash: was introduced on Cisco 1700 series routers in Release Release 12.2(4)XL. Additional features are listed in previously-released software versions for Cisco 1700 series routers, the Cross-Platform  Release Notes for Cisco IOS  Release 12.2 T  and Release 12.2 T Cisco IOS documentation.

New and Changed Information

The following sections list the new hardware and software features supported by the Cisco 1700 series for Release 12.2(4)XL6.

New Hardware Features in Release 12.2(4)XL

The following sections list the new hardware features supported by the Cisco 1700 series for Release 12.2(4)XL.

G.SHDSL WAN Interface Card

Release 12.2(4)XL supports a new G-standard Symmetrical High bit-rate Digital Subscriber Loop (G.SHDSL) WAN interface card. The Cisco G.SHDSL WAN interface can achieve rates up to 2.3 Mbps over a single copper pair with TC-PAM line coding. The card is supported on the following routers:

Cisco 1720 routers

Cisco 1750 series routers

Cisco 1751 series routers

New Software Features in Release 12.2(4)XL

The following sections describe the new software features supported by the Cisco 1700 series for Release 12.2(4)XL.

Squeeze Flash Command Support

Release 12.2(4)XL supports the command squeeze flash: on Cisco 1700 series routers. This command removes all deleted files from Flash, recovers the space they occupied, and retains the other files intact.

To enable the Squeeze Flash feature, you must first remove all existing Flash partitions (if any), erase the entire Flash using the command erase flash, and then enter the command squeeze flash:. To disable the feature, enter the command erase /no-squeeze flash:.

To enable the feature to function within an individual partition of a partitioned Flash, specify the partition using the command flash:partition_number. For example, the following command performs the Squeeze Flash feature operation on the second partition:

Router> squeeze flash:2

New Software Features in Release 12.2(4)T

For information regarding the features supported in Cisco IOS Release 12.2 T, refer to the Cross-Platform Release Notes and New Feature Documentation links at the following location on CCO:

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2(4)XL6 that can apply to the Cisco 1700 series. (Also, see the "Caveats" section.)

Fan Operation in Cisco 1700 Series Routers

The fans in some Cisco 1700 series routers stay off until thermally activated. The fans in Cisco 1760 and 1760-V routers are always on.

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(4)XL6. 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 Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity.

Another option is to go to http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl. 


Resolved Caveats - Releases 12.2(4)XL2 Through 12.2(4)XL6

This section describes unexpected behavior that is fixed in Releases 12.2(4)XL2 through 12.2(4)XL6.

Management

CSCdw65903

An error can occur with management protocol processing. Please use the following URL for further information:

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw65903 

Caveats for Release 12.2(4)XL

This section describes possibly unexpected behavior by Release 12.2(4)XL. Only severity 1 through 3 caveats are included.

CSCdt87258

Release 12.2(4)XL supports the command squeeze flash: on Cisco 1700 series routers. See the "Squeeze Flash Command Support" section.

CSCdv33932

When using the ATM-MIB on a Cisco 1700 series router with a G.SHDSL WAN interface card, the object table aal5VccTable does not become populated. Performing an SNMP query returns no response.

CSCdv35093

When running an object query, the object atmTrafficQoSClass returns a value different from the default value defined in the MIB.

CSCdv35199

When running an object query, the object atmVclAdminStatus returns the value "UP" when the ATM interface and its corresponding PVCs are down.

CSCdv39409

The command default atm vp-per-vc does not work. The configured value remains 256, irrespective of the value entered with the command default atm vp-per-vc.

CSCdv69386

The counter for the G.SHDSL WIC becomes unreliable under very heavy traffic. This caveat is a duplicate of CSCdv39226.
