Feature Overview

The SNAP feature on the Cisco IAD2420 series IAD allows service providers to rapidly deploy and configure services to the Cisco IAD platforms at customer premises without requiring configuration of the IADs at the customer site and with little or no onsite technician intervention. SNAP is part of the Cisco Networking Services (CNS) technology, which allows network products to be installed and automates many of the configuration tasks. SNAP consists of two basic functions: learning and setting the IP address and downloading the configuration for the IAD.

Each Cisco IAD2420 series IAD using SNAP includes a CNS Configuration Agent and CNS Event Agent that communicates with the CNS Configuration Registrar to enable the configuration of the IAD.

Using SNAP in conjunction with a Cisco aggregation router, a CNS Configuration Registrar, and an optional Domain Name System (DNS) server, SNAP performs the IAD configuration on the CNS Configuration Registrar and downloads the configuration to the IAD at the customer premises.

Figure 1 shows the topology of the SNAP architecture.

Figure 1 SNAP Architecture

How SNAP Works

An initial configuration is installed on the Cisco IAD2420 series IAD using Config Express either by the manufacturer or by the service provider. The IAD is installed at the customer premises site following installation procedures included with the IAD. When the IAD is switched on, the IAD connects with the aggregation router at the central office (CO), where SNAP assigns a unique IP address and an optional hostname to the IAD. After resolving the IP address through either Serial Line Address Resolution Protocol (SLARP), ATM InARP, or PPP/IPCP protocols, the system uses the DNS reverse lookup feature to assign the hostname to the IAD.

The CNS Configuration Agent on the IAD then communicates with the CNS Configuration Registrar where the CNS Configuration Registrar determines the configuration of the IAD. The CNS Configuration Registrar searches its database to determine the correct configuration template and downloads that Cisco IOS configuration file in XML format to the IAD.

Once the IOS configuration file is downloaded, the IAD is now functioning. No further configuration on the IAD is required.

The initial configuration is a full configuration of the IAD that runs automatically upon switching on the IAD on the network. This configuration provides all information needed to operate. Incremental or partial configurations are performed to update the configuration information without the network having to shut down. The incremental configuration can be delivered in an event payload in a push operation or upon request in a pull operation.

Updates can be downloaded from the CNS Configuration Registrar in a push operation initiated by the service provider. For more information on the CNS Configuration Registrar, refer to Cisco Intelligent Engine 2100 Configuration Registrar, Cisco Release 1.0.

Options for Saving the Configuration File

If the CNS configuration is set to not save the configuration file in the NVRAM of the IAD, the SNAP download procedure repeats each time the IAD turns on. By turning the IAD off and then on, this procedure repeats and permits the IAD to save the current Cisco IOS configuration file so that updates can occur without intervention by a technician.

If the CNS configuration is set to be saved in NVRAM, the original default configuration that was installed during the manufacturing process is overwritten.

For more information about changing the SNAP configuration, see the "Configuration Tasks" section.

Benefits

SNAP simplifies the installation by moving the configuration requirements from the customer to the CNS Configuration Registrar and allowing the Cisco IOS configuration to run automatically.

Provides Configuration Through the CNS Configuration Registrar

The CNS Configuration Registrar uses popular industry standards and technologies such as XML, ADSI/Active Directory, HTTP/Web Server, ASP, and Publish-Subscribe Event Bus to enable a mechanism for provisioning the configuration of Cisco IOS devices. The CNS Configuration Agent provides a facility for the CNS Configuration Registrar to configure the IADs in a plug-and-play manner.

The CNS Configuration Agent is a Cisco IOS subsystem that establishes a TCP/IP connection with the CNS Configuration Registrar to retrieve and apply the initial and incremental configurations. The CNS Configuration Registrar can be running on Windows 2000, Solaris, and Linux platforms, such as the Cisco Intelligence Engine 2100 series.

Assigns Unique IP Addresses and Hostname

SNAP applies the DNS reverse lookup feature (optional) to retrieve the hostname by passing the IP address. Then SNAP assigns the IP address and hostname to the IAD. Assigning the hostname is an optional feature.

Reduces Technical Personnel Requirements

SNAP permits Cisco IAD2420 series IADs to be installed by a person with limited or no technical experience. SNAP does not require a network engineer or technician for installation.

Speeds Deployment

Upon receiving the Cisco IAD2420 series IAD at the customer premises, the unit can be immediately installed by following simple installation instructions, without any knowledge or use of Cisco IOS software.

Permits Direct Shipping

SNAP permits the Cisco IAD2420 series IADs to be shipped directly to the end-user site to eliminate warehousing of inventory and manual handling. Configuration occurs automatically upon connection to the network.

Permits Remote Updates

Remote configuration updates, service additions, and deletions are handled through SNAP. The CNS Configuration Registrar performs a push operation to send the information to the Cisco IAD2420 series IAD.

Restrictions

Configuration Tasks

The Simple Network-Enabled Auto-Provision feature allows the Cisco IAD2420 series IAD to be connected and configured automatically. Configuration Express loads a minimal set of Cisco IOS configuration commands for the IAD in the startup-configuration file in the NVRAM, either at the manufacturer or at the service provider premises. The IAD is ready to be installed at the customer premises with no further configuration.

If the service provider desires to change the configuration or install a custom configuration, these tasks allow a new configuration to be loaded. Each task in the list is optional and is not required for the initial installation of the Cisco IAD2420 series IAD.

•Configuring the CNS Configuration Agent (Optional)

•Configuring the CNS Event Agent (Optional)

•Full Configuration of Cisco IAD2420 Series IAD (Optional)

•Incremental Configuration of Cisco IAD2420 Series IAD (Optional)

Configuring the CNS Configuration Agent (Optional)

The CNS Configuration Registrar uses templates to build the configuration file. Refer to Configuration Registrar Administration, Cisco Release 1.0, for additional information on using the CNS Configuration Registrar.

Each parameter in the template must have a directory-customized schema attribute associated. Create the template in the CNS Configuration Registrar through the Edit Template graphical user interface (GUI). Each Cisco IAD2420 series IAD object in the CNS Configuration Registrar must be associated with one specific template, although one template may be applied to multiple IAD objects. The template does not have interactive ability. You must enter the value in the Edit Parameter GUI of the CNS Configuration Registrar. If there is no value assigned for the attribute, the attribute value in the configuration file is empty.

Configuring the CNS Event Agent (Optional)

To initiate an event between the IAD and the CNS Configuration Registrar, the connection must be configured by the CNS Event Agent. To configure the CNS Event Agent, use the following commands beginning in global configuration mode:

	Command	Purpose
Step 1	Router(config)# cns event {ipaddress | hostname} {port-number | backup }	Configures the Event Gateway for CNS. ipaddress—IP address of the event gateway. hostname—The host name of the event gateway. port-number—(Optional) Port number for the event gateway. The default port number is 11011. backup—(Optional) Indicates that the event agent is the backup gateway.
Step 2	Router(config)# show cns event	Displays information about the CNS Event Agent.

Full Configuration of Cisco IAD2420 Series IAD (Optional)

The full or initial configuration of the Cisco IAD2420 series IAD occurs when the IAD is initialized on the network. This configuration occurs automatically at the customer premises. If desired, this configuration can be performed manually.

After connecting the IAD to the network where the aggregation router resides and switching it on, the IAD boots up and the commands are executed.

SNAP assigns the IAD with the unique IP address or hostname. After resolving the IP address through SLARP, ATM InARP, or PPP protocols, the system uses the DNS reverse look up feature (optional) to assign the hostname to the IAD (optional) and invokes the CNS agents to download the initial configuration from the CNS Configuration Registrar.

To manually perform the initial configuration, use the CNS Configuration Registrar and follow these steps:
