Introduction
The Cisco Configuration Engine 3.5.1 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 either Linux or Solaris.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, where a new device can automatically connect with the Cisco Configuration Engine and ask for the correct configuration.
What's New in this Release
Cisco Configuration Engine 3.5.1 supports the following features:
•Dynamic Gateway Port Assignment
•Text only Device Configuration
VMware Support
You can install and run the Cisco Configuration Engine in VMware environment. The Cisco Configuration Engine supports the VMware environment starting from the Cisco Configuration Engine 3.5. The host operation system for VMware could be either Windows or Linux. The guest operating system for Cisco Configuration Engine is RHEL4 or RHEL5.
Support for RHEL5
The Cisco Configuration Engine supports RHEL5 starting from the Cisco Configuration Engine 3.5.
Dynamic Gateway Port Assignment
The dynamic gateway port assignment enhancement enables to perform the true Zero Touch Deployment (ZTD).
Note In the Cisco Configuration Engine, the event gateway ports 11011 and 11012 are reserved for port automatic allocation starting from the Cisco Configuration Engine release 3.5. If a user wants to zero touch deploy the devices or already have deployed the devices currently using these two ports, then the user should enable this feature and enter the correct cns event command during Cisco Configuration Engine setup. For more information, see "Scalability among Event Gateway Ports" chapter in the Cisco Configuration Engine Installation and Configuration guide.
External Authentication
The Cisco Configuration Engine supports external user authentication. From the 3.5 release, the Cisco Configuration Engine supports Lightweight Directory Access Protocol (LDAP)-based external authentication integrating with MS Active Directory.
ZTD Over Serial Line
The Cisco Configuration Engine supports ZTD over a serial line.
UDI Support
The Cisco Configuration Engine provides full Unique Device Identifier (UDI) support.
Text only Device Configuration
The Cisco Configuration Engine listing of device configuration currently has a line number in front. This prevents the customer from cut and paste a portion of a configuration.
Multizone System Setup
The Cisco Configuration Engine can segregate the HTTP/HTTPS and TCP traffic based on the source IP address or the network interface. This traffic segregation enables the Cisco Configuration Engine to support multi-zone deployment architecture.
Note The installation of the Cisco Configuration Engine software does not offer the multizone system setup by default. If you require a multizone system setup, you must enable the multizone feature during the system setup. To setup multiple IP addresses on the Cisco Configuration Engine server, you must manually customize the network parameters of the server to have multiple IP addresses. For more information, see Chapter 6 "Setting Up a Multizone System" in Cisco Configuration Engine Installation and Configuration Guide.
FTP and SFTP Support
The Cisco Configuration Engine supports FTP and SFTP for transferring device configuration and templates to and from another external application.
Accessibility
The Cisco Configuration Engine complies with the Cisco accessibility requirement.
Health Checking Utility
A wrapper resource health checking utility is provided in release 3.5 to monitor the health of Event Gateways and Tibco Rendezvous Daemon. If any of the processes stops, the health checking utility restarts the process and logs a message in /var/log/CNSCE/resource_monitor/resource_monitor.log file. This utility (resource_monitor_daemon) starts during the Configuration Engine setup and stops when the Configuration Engine server stops.

Cisco IOS Dependencies
Table 2 lists Cisco IOS versions with corresponding versions of Configuration Engine, including feature limitations associated with each version.
Router Configuration
The Cisco Configuration Engine 3.5.1 software needs to be installed and prepared first before configuring a device. The device can obtain its initial configuration from the Cisco Configuration Engine 3.5.1.
For information about Cisco Flow-Through Provisioning, see http://www.cisco.com/en/US/docs/ios/12_2t/12_2t8/feature/guide/ftsnap26.html.
Limitations and Restrictions
•If you download a configuration that changes username, password, enable password, or IP address for a non-agent-enabled device, you need to modify the corresponding Intelligent Modular Gateway (IMGW) hop information for the device to update it with the new username, password, enable password, and IP address.
•TFTP:
–No new files can be created and files cannot be deleted. However, existing files can be overwritten ONLY if they are publicly writable. The permissions of the files placed into the FTP directory can be controlled by the SFTP user managing 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, TFTPD allows only publicly readable files (o+r) to be accessed. Files may be written only if they already exist and are publicly writable.
•Device Name values may only contain: period (.), underscore (_), hyphen (-), and alphanumeric characters.
•Group Name values may only contain: underscore (_) and alphanumeric characters.
•The configuration entry in /etc/hosts on the server where CE is installed must comply with the following format:
<server IP> <hostname> <FQDN>
172.27.117.199 imgw-test16 imgw-test16.cisco.com
•CNS Agent should use the same config event and image ID when using CE to manage devices.
•If you download a configuration that changes the CNS password, you need to use CE to resync the device.
•Attribute name must begin with alpha characters only when adding a new attribute through the Directory Manager.
