New Features in Cisco CG-OS Release CG1
Table 1 lists the new features added in this release.
Table 1 New Features in Cisco CG-OS Release CG1
Release Feature Description Related DocumentationCG1(5) and later
Incremental software image upgrade
The CG-OS software image files (kickstart and system image) are now available in two formats:
•Full software image (large file)
•Incremental software image (smaller patch file)
The incremental image file contains only the differences between the previous software image and the new software image.
Using the CLI, you can combine the incremental image file from the new release with the full image file from the previous release to get the equivalent of the full image file for the new release.
The combined software image file can be used to upgrade the software on the Cisco CG-OS router with the install all command.
Note This feature is currently supported on CG3(1) and CG1(5) and later only. Therefore, you can upgrade from CG1(5) and later CG1 releases to CG3(1) and later releases, using this feature.
See Generating Software Images Using Incremental Image Files.
CG1(4) and later
Support for setting hostname and password for CDMA Simple IP authentication
The CDMA module now includes Point-to-Point Protocol (PPP) Challenge Handshake Authentication Protocol (CHAP) type 6 and type 7 password support.
CLI commands for Simple IP authentication have been added to enable you to configure a hostname and password on a cellular interface to be used for PPP negotiation.
Currently, the password is not subject to password strength-check configuration because the Cisco CG-OS router acts as the PPP client rather than a server. Typically, the hostname and password are managed and set by the cellular network-side server with strength-check functionality.
For feature overview and configuration details, see the Cisco Connected Grid Cellular 3G Module for CGR 1000 Series Installation and Configuration Guide.

Installation Notes
This section addresses the following topics:
•Determining the Software Version
•Upgrading to a New Software Release
•Erasing the Configuration File
Determining the Software Version
To identify the software version operating on the Cisco CG-OS router, enter the following command.
Upgrading to a New Software Release
You can upgrade the software on the Cisco CG-OS router by employing the install all command.
Listed below are the two possible approaches when downloading images using the install all command. You must select one of the following approaches:•Download the images (kickstart and system image) from a remote server into the volatile memory of the Cisco CG-OS router by employing the install all command to specify the path to the remote server and the protocol. After the download, the software installation begins automatically.
•Download the images (kickstart and system image) from a local server directly into the bootflash of the Cisco CG-OS router, and then manually enter the install all command to initiate the software upgrade.
The following table provides detailed command syntax for the install all command.
EXAMPLES
This example shows how to download the software images from a remote FTP server onto the
Cisco CG-OS router bootflash. After download, the software installation starts automatically on the

Note The Cisco CG-OS router reboots after a successful installation.
Generating Software Images Using Incremental Image Files
The kickstart and system images are both available as incremental image files. Incremental image files contain only the differences between the previous software image and the new software image. An incremental software image can be combined with the previous software image to get the equivalent of the full version of the new software image, which can then be installed with the install all command, as described in the Upgrading to a New Software Release section.
For example, an incremental image file for CG3(1) contains only the differences between CG3(1) and the previous software release (that supports this feature), CG1(6). You can combine the CG3(1) incremental image file with the CG1(6) software image to get the equivalent of the full version of the CG3(1) software image. There are separate incremental image files for the kickstart and system images.
To generate software images using incremental patch files, you use the image-patch command in privileged EXEC mode. The following table provides detailed command syntax for the image-patch command.
Erasing the Configuration File
When you enter the write erase [boot | debug | secrets] command, it erases all of the persistent memory of the Cisco CG-OS router except for items noted in the table below.
Important Notes
Battery Backup Unit
To prevent the battery backup unit (BBU) from discharging during transport or servicing of the Cisco CG-OS router, disable the BBU automatic discharge feature using the system software. Details on this procedure, please see the Installing Battery Backup chapter within the Cisco 1240 Connected Grid Router Hardware Installation Guide.
Guidelines and Limitations
Refer to the "Guidelines and Limitations" section of each chapter within the Cisco Connected Grid Routers Software Configuration Guides listed in Table 2 and the highlighted Notes, Warnings, and Cautions throughout all Cisco CG-OS router documentation.
Limitations and Restrictions
Cisco recommends that you review this section before you begin working with the router. These limitations might not be fixed, or do not have a workaround. Some features might not work as documented, and some features might be affected by recent changes to the switch module hardware or software.
•CSCtw44740
Symptom: In some cases, over the air service provisioning (OTASP) might not be successful or might time out.
Workaround: Re-attempt OTASP activation.
•CSCty61792
Symptom: The CGR 1000 fails certificate authentication.
Conditions: This issue can occur when authenticating the router using Simple Certificate Enrollment Protocol. If the enrollment profile refers to a Cisco IOS registration agent (RA), and the RA refers to a sub-certificate authority (SubCA) instead of a certificate authority (CA), the authentication fails.
Workaround: Authenticate to the SubCA over a terminal connection, or authenticate to the SubCA but do not use a Cisco IOS RA.
•CSCud12701
Symptom: IKEv2 handshake fails given IKEv2 can only accept messages of up to 2048 bytes.
Conditions: CGR 1000 was configured with IKEv2 for authentication by using RSA signatures and certificates. The IKEv2 authentication resulted in packets that were larger than 2048, which IKEv2 could not accept.
Workaround: There is no workaround.
Caveats
This section addresses the open and resolved caveats in CG1 releases and provides information on how to use the Bug Toolkit to find further details on those caveats.
Open Caveats
