These release notes describe new features and significant software components that support Cisco IOS Release 12.0(3)XG for the Cisco 3600 series routers. Cisco IOS Release 12.0(3)XG is based on Cisco IOS Release 12.0(3)T.
Use these release notes with the cross-platform Release Notes for Cisco IOS Release 12.0 located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
For a list of software caveats that apply to Release 12.0(3)XG, refer to the "Caveats" section.
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 WAN (wide-area network) 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.

| 1Added in Cisco IOS Release 12.0(3)XG. 2Cisco 3640 routers only |
This section describes a new feature introduced for the Cisco 3600 series in Cisco IOS Release 12.0(3)XG.
The Voice over Frame Relay (VoFR) capabilities that were introduced on the Cisco MC3810 multiservice access concentrator beginning with IOS Release 11.3 are now extended to the Cisco 3600 series router platforms.
The following additional functionality is supported in Release 12.0(3)XG:
When VoFR is implemented on a Cisco router, the router can carry voice traffic, such as telephone calls and faxes over a Frame Relay network.
This section contains important information about use of your Cisco IOS Release 12.0(3)XG software.
Older Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently being migrated into more scalable MIBs, without affecting existing Cisco IOS products or NMS applications. Application developers should update from deprecated MIBs to the replacement MIBs as shown in the table below.
| Deprecated MIB | Replacement |
|---|---|
OLD-CISCO-APPLETALK-MIB | RFC1243-MIB |

This section contains open caveats for the current Cisco IOS maintenance release only. Caveats describe unexpected behavior or defects in Cisco IOS software releases. The caveats listed below are severity 3, moderately seriouss, with the exception of CSCdm17845, as noted in the description.
For information on caveats in Cisco IOS Release 12.0, refer to the document Caveats for Cisco IOS Release 12.0 that describes caveats affecting all maintenance releases. Because Release 12.0(3)XG is based on Release 12.0, all caveats in Release 12.0 are also in Release 12.0(3)XG.
For information on other caveats that also apply to this release, refer to the Caveats for Cisco IOS Release 12.0 T document. This caveats document lists severity 1 and 2 caveats for Release 12.0 T. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
The following sections describe the documentation available for the Cisco 3600 series. Typically, these documents consist of hardware installation guides, software installation guides, Cisco IOS configuration and command references, system error messages, feature modules, and other documents.
Documentation is available as printed manuals or electronic documents, except for feature modules, which are only available online.
You can find the most up-to-date documentation on CCO and the Documentation CD-ROM. These electronic documents may contain updates and modifications made after the hardcopy documents were printed.
Use these release notes in conjunction with the documents listed in the following sections:
The following documents are specific to Cisco IOS Releases 12.0 T and 12.0, on which Release 12.0(3)XG is based. They are located on CCO and the Documentation CD-ROM:
The documents listed below are available for the Cisco 3600 series routers. These documents are also available online at Cisco Connection Online (CCO) and on the Documentation CD-ROM.

Feature modules describe new features supported by Cisco IOS Release 12.0 T, 12.0(3)XG, and other ED releases and are updates to the Cisco IOS documentation set. They consist of a brief overview of the feature, benefits, configuration tasks, and a command reference. As updates, the features modules are available online only. The feature module information is included in the next printing of the Cisco IOS documentation set.

The Cisco IOS software documentation set consists of the Cisco IOS configuration guides, Cisco IOS command references, and several other supporting documents. These documents are shipped with your order in electronic form on the Documentation CD-ROM---unless you specifically ordered the printed versions.
Each module in the Cisco IOS documentation set consists of two books: a configuration guide and a corresponding command reference. Chapters in a configuration guide describe protocols, configuration tasks, Cisco IOS software functionality, and comprehensive configuration examples. Chapters in a command reference provide complete command syntax information. Each configuration guide can be used in conjunction with its corresponding command reference.
