Cisco Configuration Engine 3.5.5 is a network management application that acts as a configuration service for automating the deployment and management of network devices and services. The
Cisco Configuration Engine runs on host systems running Linux.
The Cisco Configuration Engine is a network management software application that provides a highly scalable, secure, and reliable solution for remote deployment. By taking advantage of intelligent agents inside Cisco IOS Software, the Cisco Configuration Engine enables the call-home architecture, which enables a new device to automatically connect with the Cisco Configuration Engine and obtain the correct configuration.
Cisco Configuration Engine 3.5.5 can now scale up to 30,000 devices through 60 ports on RHEL 6 (64-bit) servers. Each port will have a maximum capacity of 500 devices.
1. Cisco Configuration Engine 3.5.5 Release only supports the RHEL6 (64-bit) operating system and the support for the older versions (RHEL4 32-bit, RHEL 5 32-bit and Solaris 10) have been removed.
2. Cisco Configuration Engine 3.5.5 no longer supports IMGW (Non-Agent) devices.
a. User cannot add IMGW (Non-agent) devices through GUI.
b. User cannot add IMGW (Non-agent) devices through bulk upload as well as through Web services.
c. Also, while migration IMGW(Non-agent), devices will not be added to Cisco Configuration Engine 3.5.5
3. Cisco Configuration Engine 3.5.5 no longer supports Cisco PIX firewall devices.
4. Cisco Configuration Engine 3.5.5 does not use Tibco® and /TibGate for event messaging and gateway functionality respectively. Also, the following changes in the Configuration Engine 3.5.5 SDK:
a. Tibco Rendezvous® based Event API’s will not be available.
b. Solaris 10 packages for SDK will not be available for use.
c. Cisco Configuration Engine will only support Web services SDK in 3.5.5
If you have custom attributes defined in the Cisco Configuration Engine, and are planning to migrate from Release 3.5.3 or earlier to Cisco Configuration Engine 3.5.5, run the schema patch script. The patch script will be a part of Cisco Configuration Engine Release 3.5.5; the patch script file is available in the RPMS/patch directory when you untar the Cisco Configuration Engine 3.5.5 tar file. After applying this patch, you can run search queries based on your custom attributes.
To run the patch script, follow these steps:
1. Untar the Cisco Configuration Engine 3.5.5 tar file and go to the RPMS/patch folder.
2. Run the./schema_patch.sh script.
Example of Data Export Prompts:
For more information on schema patch script, see the Cisco Configuration Engine Installation and Configuration Guide.
Note If you are using releases prior to Release 3.5.3, execute the schema patch to upgrade to Release 3.5.5. If you are using Release 3.5.3, you do not have to execute this patch.
Table 1 lists the Cisco IOS versions with the corresponding versions of the Cisco Configuration Engine, including feature limitations associated with each version.
The Cisco Configuration Engine 3.5.5 software should be installed before configuring a device. The device can obtain its initial configuration from the Cisco Configuration Engine 3.5.5.
– No new files can be created, and existing files cannot be deleted. However, existing files can be overwritten if they are publicly writable. The permissions for the files placed in the FTP directory can be controlled by the SFTP user managing the files in the FTP directory.
– The TFTP service does not require an account or password on the server system. Because of the lack of authentication information, TFTP allows only publicly readable files to be accessed.

Symptom: Unable to delete a group having IMGW(Non Agent) devices,after migration to 3.5.5.
Conditions: Cisco Configuration Engine Software, 3.5.4 is installed in RHEL6 (64-bit SMP, kernel 2.6, and SELinux disabled).
Workaround: Delete the group in LDAP.
Symptom: User is unable to configure cns event with source interface during Configuration Engine setup.
Conditions: This problem occurs during the setup of Cisco Configuration Engine. when the setup prompt to enter cns command as shown below:
"Enter CNS Event command: cns event bgl-dt-CE3 keepalive 120 2 reconnect 10
The user is not able to provide “cns event bgl-dt-ce3 source gigabitEthernet0/0 keepalive 120 2 reconnect 10”
Workaround: Configure route’s such as not to use source interface on the cns commands.
Symptom: FTP and TFTP does not work.
Conditions: This condition occurs when Reloading xinetd...
/etc/rc.d/init.d/xinetd reload
Reloading configuration: ^[[60G[^[[0;31mFAILED^[[0;39m]^M.
Workaround: Execute etc/rc.d/init.d/xinetd restart from the server command line prompt to start the xinetd.
Symptom: Installed CE using ce_install.sh script. Verified the user called setup exists in /etc/password file.
Conditions: This condition occurs when the Cisco Configuration Engine Software, 3.5.4 is installed in
RHEL6 (64-bit SMP, kernel 2.6, and SELinux disabled)
Workaround: Deleted the setup user using userdel command in $CISCO_CE_HOME/bin directory and Run./setup script and perform the setup.
Symptom: While trying to update httpd, update is not happening due to the unsatisfied dependencies with respect to the packages.
Unset the $LD_LIBRARY_PATH and execute : rpm –Va from server command line prompt.
Conditions: Cisco Configuration Engine Software, 3.5.4 is installed in RHEL6 (64-bit SMP, kernel 2.6, and SELinux disabled).
