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(5)YC3 supports the same feature sets as Releases 12.1 and 12.1 T, but Release 12.1(5) can include new features supported by the Cisco SOHO series routers.
Table 3 lists the features and feature sets supported by the Cisco SOHO series routers in Cisco IOS Release 12.1(5)YC3, and uses the following conventions:

Note
New and Changed Information
The following section lists the new software features supported by the Cisco SOHO series for Release 12.1(5)YC3 and above.
New Software Features in Release 12.1(5)YC1
The following new software features are supported by the Cisco SOHO series for Cisco IOS Release 12.1(5)YC1 and above:
OpenDSL
This feature implements auto-provisioning of the Cisco SOHO 70 Series routers. Auto-provisioning operates at bootup, and includes two procedures: Device Authentication and Image Maintenance. The router will be authenticated at bootup using its vendor ID and serial number. It then requests the Proxy Element to download its configuration file, and configures itself from CLIs in this file. It then polls for configuration changes, and downloads a new image and configuration file, if available, to retrieve the latest changes.
Limitations and Restrictions
The CISCO-DSL-CPE-MIB is partially supported by the Cisco SOHO 70 routers for the OpenDSL feature. Only those objects used in the Device Authentication and Image Maintenance procedures are supported. These objects are:

Important Notes
The following sections contain important notes about Cisco IOS Release 12.1(5)YC3.
OpenDSL Issues for the Cisco SOHO 70 Routers
The Cisco SOHO 70 routers with OpenDSL are preloaded with a CLI configuration such as "autoconfigure" instead of with no configuration. If a router is not loaded with some configuration, it will enter the initial console-user configuration dialog, which requires input from the user to get the router started.
If the image has been deleted by the user, the user needs to clear flash memory to allow the downloading of a new image during auto provisioning.
There is no WarmRestart action available for the routers. Selecting WarmRestart on CDCM will not reload the routers.
Configuration files must conform to the following.

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 12.1 T, see Caveats for Cisco IOS Release 12.1 T.
All caveats in Cisco IOS Release 12.1 are also in Cisco IOS Release 12.1 T.
For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which lists severity 1 and 2 caveats and is located on Cisco.com and the Documentation CD-ROM.
Note
Resolved Caveats - Releases 12.1(5)YC2 and 12.1(5)YC3
This section describes unexpected behavior that is fixed in Releases 12.1(5)YC2 and 12.1(5)YC3.

Caveats for Release 12.1(5)YC1
This section describes possibly unexpected behavior by Release 12.1(5)YC1, specific to the Cisco SOHO 70 routers. These caveats are all of severity 3 (moderate).
Resolved Caveats - Release 12.1(5)YC1
This section describes possibly unexpected behavior by software releases prior to Release 12.1(5)YC1 that have been resolved in Release 12.1(5)YC1 and above.
CSCdt77246:
When a router is configured for PPPoE and IP NAT, and an incoming packet does not contain an MSS field or its TCP option field is not terminated by 0, the router might stop routing packets. This defect has been fixed in 12.1(5)YC1 release.
CSCdt35967:
When using CODEC g711alaw & g711ulaw, c827-4v fails to make an outgoing call to another Cisco voice gateway. This defect has been fixed in 12.1(5)YC1 release.
CSCds92106:
C827-4v may hang during system bootup. This defect has been fixed in 12.1(5)YC1 release.
Unresolved Caveats - Release 12.1(5)YC1
This section describes possibly unexpected behavior by Release 12.1(5)YC1.
CSCdt47054
When the router is configured to an ATM PVC with PPPoE encapsulation, it unexpectedly resets when the ATM PVC is removed in a subsequent configuration while the PPPoE session is still active.
CSCdt61879
When the configuration file URL in the ImageTable script is changed to point to a different, new configuration file and the router is reloaded, the previous configuration file is downloaded, rather than the new one. The problem has been traced to the cache in the PE, which retains the previous URL of the configuration file and sends that URL to the tftp server. The workaround is to clear the PE cache before reloading the router. This forces the PE to reload its cache with the latest information from the ImageTable script.
CSCdt61928
The router unexpectedly resets when executing cl or de commands in exec mode. The workaround is to expand these commands to at least cle and deb.
CSCdt61929
A zero byte configuration file will cause the router to operate in a loop and repeatedly download the configuration file.
