Cisco Networking Services
Cisco Networking Services is a foundation technology for linking users to networking services and provides the infrastructure for the automated configuration of large numbers of network devices. Many IP networks are complex with many devices, and each device must currently be configured individually. When standard configurations do not exist or have been modified, the time involved in initial installation and subsequent upgrading is considerable. The volume of smaller, more standardized, customer networks is also growing faster than the number of available network engineers. Internet service providers (ISPs) now need a method for sending out partial configurations to introduce new services. To address all these issues, Cisco Networking Services has been designed to provide “plug-and-play” network services using a central directory service and distributed agents. Cisco Networking Services features include Cisco Networking Services configuration and event agents and a Flow-Through Provisioning structure. The configuration and event agents use a Cisco Networking Services configuration engine to provide methods for automating initial Cisco device configurations, incremental configurations, and synchronized configuration updates, and the configuration engine reports the status of the configuration load as an event to which a network monitoring or workflow application can subscribe. The Cisco Networking Services Flow-Through Provisioning uses the Cisco Networking Services configuration and event agents to provide an automated workflow, eliminating the need for an on-site technician.
Cisco Networking Services EXEC Agent
The CNS EXEC agent allows a remote application to execute an EXEC mode CLI command on a Cisco device by sending an event message that contains the command. A restricted set of EXEC show commands is supported.
Cisco Networking Services Results Messages
When a partial configuration has been received by the device, each line of the configuration will be applied in the same order as it was received. If the Cisco parser has an error with one of the lines of the configuration, then all the configuration up to this point will be applied to the device, but none of the configuration beyond the error will be applied. If an error occurs, the cns config partial command will retry until the configuration successfully completes. In the pull mode, the command will not retry after an error. By default, NVRAM will be updated except when the no-persist keyword is configured.
A message will be published on the Cisco Networking Services event bus after the partial configuration is complete. The Cisco Networking Services event bus will display one of the following status messages:
- cisco.mgmt.cns.config.complete—Cisco Networking Services configuration agent successfully applied the partial configuration.
- cisco.mgmt.cns.config.warning—Cisco Networking Services configuration agent fully applied the partial configuration, but encountered possible semantic errors.
- cisco.mgmt.cns.config.failure (CLI syntax)—Cisco Networking Services configuration agent encountered a command line interface (CLI) syntax error and was not able to apply the partial configuration.
- cisco.mgmt.cns.config.failure (CLI semantic)—Cisco Networking Services configuration agent encountered a CLI semantic error and was not able to apply the partial configuration.
With the CNS Enhanced Results Messages feature, a second message is sent to the subject “cisco.cns.config.results” in addition to the appropriate message above. The second message contains both overall and line-by-line information about the configuration that was sent and the result of the action requested in the original message. If the action requested was to apply the configuration, then the information in the results message is semantic in nature. If the action requested was to check syntax only, then the information in the results message is syntactical in nature.
Cisco Networking Services Message Formats
SOAP Message Format
Using the Service-Oriented Access Protocol (SOAP) protocol provides a way to format the layout of Cisco Networking Services messages in a consistent manner. SOAP is a lightweight protocol intended for exchanging structured information in a decentralized, distributed environment. SOAP uses extensible markup language (XML) technologies to define an extensible messaging framework that provides a message format that can be exchanged over a variety of underlying protocols.
Within the SOAP message structure, there is a security header that enables Cisco Networking Services notification messages to authenticate user credentials.
Cisco Networking Services messages are classified into three message types: request, response and notification. The formats of these three message types are defined below.
Request Message
The following is the format of a Cisco Networking Services request message to the Cisco device:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP:Envelope xmlns:SOAP="http://www.w3.org/2003/05/soap-envelope">
<SOAP:Header>
<wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext" SOAP:mustUnderstand="0">

</cns:Request>
<cns:Time>2003-04-23T20:27:19.847Z</cns:Time>
</cns:cnsHeader>
</SOAP:Header>
<SOAP:Body xmlns="http://www.cisco.com/management/cns/config">
<config-event config-action="read" no-syntax-check="TRUE">
<config-data>
<config-id>AAA</config-id>
<cli>access-list 1 permit any</cli>
</config-data>
</config-event>
</SOAP:Body>
</SOAP:Envelope>
 Note | The ReplyTo field is optional. In the absence of the ReplyTo field, the response to the request will be sent to the destination where the request originated. The body portion of this message contains the payload and is processed by the Cisco Networking Services agent mentioned in the Agent field. |
Response Message
The following is the format of a Cisco Networking Services response message from the Cisco device as a response to a request:
?xml version="1.0" encoding="UTF-8"? SOAP:Envelope xmlns:SOAP="http://www.w3.org/2003/05/soap-envelope" SOAP:Header wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext" SOAP:mustUnderstand="true" wsse:UsernameToken wsse:Username infysj-7204-8 /wsse:Username wsse:Password NTM3NTg2NzIzOTg2MTk2MjgzNQ==/wsse:Password /wsse:UsernameToken /wsse:Security CNS:cnsHeader Version="2.0" xmlns:CNS="http://www.cisco.com/management/cns/envelope" CNS:Agent CNS_CONFIG /CNS:Agent CNS:Response CNS:correlationID IDENTIFIER /CNS:correlationID /CNS:Response CNS:Time 2005-06-23T16:27:36.185Z /CNS:Time /CNS:cnsHeader /SOAP:Header SOAP:Body xmlns="http://www.cisco.com/management/cns/config" config-success config-id AAA /config-id /config-success /SOAP:Body /SOAP:Envelope
Note | The value of CorrelationId is echoed from the corresponding request message. |
The body portion of this message contains the response from the Cisco device to a request. If the request is successfully processed, the body portion contains the value of the response put in by the agent that processed the request. If the request cannot be successfully processed, then the body portion will contain an error response.
Notification Message
The following is the format of a Cisco Networking Services notification message sent from the Cisco device:
?xml version="1.0" encoding="UTF-8"? SOAP:Envelope xmlns:SOAP="http://www.w3.org/2003/05/soap-envelope" SOAP:Header wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext" SOAP:mustUnderstand="true" wsse:UsernameToken wsse:Username dvlpr-7200-2 /wsse:Username wsse:Password /wsse:Password /wsse:UsernameToken /wsse:Security CNS:cnsHeader version="2.0" xmlns:CNS="http://www.cisco.com/management/cns/envelope" CNS:Agent CNS_CONFIG_CHANGE/CNS:Agent CNS:Notify /CNS:Notify CNS:Time 2006-01-09T18:57:08.441Z/CNS:Time /CNS:cnsHeader /SOAP:Header SOAP:Body xmlns="http://www.cisco.com/management/cns/config-change" configChanged version="1.1" sessionData="complete" sequence lastReset="2005-12-11T20:18:39.673Z" 7 /sequence changeInfo user/user async port con_0 /port /async when absoluteTime 2006-01-09T18:57:07.973Z /absoluteTime /when /changeInfo changeData changeItem context /context enteredCommand cli access-list 2 permit any /cli /enteredCommand oldConfigState cli access-list 1 permit any /cli /oldConfigState newConfigState cli access-list 1 permit any /cli cli access-list 2 permit any /cli /newConfigState /changeItem /changeData /configChanged /SOAP:Body /SOAP:Envelope
A notification message is sent from the Cisco device without a corresponding request message when a configuration change is made. The body of the message contains the payload of the notification and it may also contain error information. If the request message sent to the Cisco device fails in XML parsing and the CorrelationId field cannot be parsed, then an error notification message will be sent instead of an error response.
Error Reporting
Error is reported in the body of the response or a notification message in the SOAP Fault element. The following is the format for reporting errors.
?xml version="1.0" encoding="UTF-8"? SOAP:Envelope xmlns:SOAP="http://www.w3.org/2003/05/soap-envelope" SOAP:Header wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext" SOAP:mustUnderstand="true" wsse:UsernameToken wsse:Username dvlpr-7200-2 /wsse:Username wsse:Password /wsse:Password /wsse:UsernameToken /wsse:Security CNS:cnsHeader version="2.0" xmlns:CNS="http://www.cisco.com/management/cns/envelope" CNS:Agent CNS_CONFIG /CNS:Agent CNS:Response CNS:correlationID SOAP_IDENTIFIER /CNS:correlationID /CNS:Response CNS:Time 2006-01-09T19:10:10.009Z /CNS:Time /CNS:cnsHeader /SOAP:Header SOAP:Body xmlns="http://www.cisco.com/management/cns/config" SOAP:Detail config-failure config-id AAA /config-id error-info line-number 1 /line-number error-message CNS_INVALID_CLI_CMD /error-message /error-info /config-failure /SOAP:Detail /SOAP:Fault /SOAP:Body /SOAP:Envelope
Cisco Networking Services IDs
The Cisco Networking Services ID is a text string that is used exclusively with a particular Cisco Networking Services agent. The Cisco Networking Services ID is used by the Cisco Networking Services agent to identify itself to the server application with which it communicates. For example, the Cisco Networking Services configuration agent will include the configuration ID when communicating between the networking device and the configuration server. The configuration server uses the Cisco Networking Services configuration ID as a key to locate the attribute containing the Cisco CLI configuration intended for the device that originated the configuration pull.
The network administrator must ensure a match between the Cisco Networking Services agent ID as defined on the routing device and the Cisco Networking Services agent ID contained in the directory attribute that corresponds to the configuration intended for the routing device. Within the routing device, the default value of the Cisco Networking Services agent ID is always set to the hostname. If the hostname changes, the Cisco Networking Services agent ID also changes. If the Cisco Networking Services agent ID is set using the CLI, any change will be followed by a message sent to syslog or an event message will be sent.
The Cisco Networking Services agent ID does not address security issues.
Cisco Networking Services Password
The Cisco Networking Services password is used to authenticate the Cisco Networking Services device. You must configure the Cisco Networking Services password the first time a device is deployed, and the Cisco Networking Services password must be the same as the bootstrap password set on the Configuration Engine (CE). If both the device and the CE bootstrap password use their default settings, a newly deployed device will be able to connect to the CE. Once connected, the CE manages the Cisco Networking Services password. Network administrators must ensure not to change the Cisco Networking Services password. If the Cisco Networking Services password is changed, connectivity to the CE will be lost.
Cisco Networking Services Zero Touch
The Cisco Networking Services Zero Touch feature provides a zero touch deployment solution where the device contacts a Cisco Networking Services configuration engine to retrieve its full configuration automatically. This capability is made possible through a single generic bootstrap configuration file common across all service provider end customers subscribing to the services. Within the Cisco Networking Services framework, customers can create this generic bootstrap configuration without device-specific or network-specific information such as interface type, line type, or controller type (if applicable).
The Cisco Networking Services connect functionality is configured with a set of Cisco Networking Services connect templates. A Cisco Networking Services connect profile is created for connecting to the Cisco Networking Services configuration engine and to implement the Cisco Networking Services connect templates on a Customer Premise Equipment (CPE) device. Cisco Networking Services connect variables can be used as placeholders within a Cisco Networking Services connect template configuration. These variables, such as the active DLCI, are substituted with real values before the Cisco Networking Services connect templates are sent to the device’s parser.
To use the zero touch functionality, the device that is to be initialized must have a generic bootstrap configuration. This configuration includes Cisco Networking Services connect templates, Cisco Networking Services connect profiles, and the cns config initial command. This command initiates the Cisco Networking Services connect function.
The Cisco Networking Services connect functionality performs multiple ping iterations through the device’s interfaces and lines, as well as any available controllers. For each iteration, the Cisco Networking Services connect function attempts to ping the Cisco Networking Services configuration engine. If the ping is successful, the pertinent configuration information can be downloaded from the Cisco Networking Services configuration engine. If connectivity to the Cisco Networking Services configuration engine is unsuccessful, the Cisco Networking Services connect function removes the configuration applied to the selected interface, and the Cisco Networking Services connect process restarts with the next available interface specified by the Cisco Networking Services connect profile.
The Cisco Networking Services Zero Touch feature provides the following benefits:
How to Configure Cisco Networking Services
- Deploying the Cisco Networking Services Device
- Configuring Advanced Cisco Networking Services Features
- Troubleshooting Cisco Networking Services Agents
Deploying the Cisco Networking Services Device
Incremental or partial configuration allows the remote device to be incrementally configured after its initial configuration. You must perform these configurations manually through the Cisco Networking Services configuration engine. The registrar allows you to change the configuration templates, edit parameters, and submit the new configuration to the device without a software or hardware restart.
Perform this task to manually install an initial Cisco Networking Services configuration.
Your remote device arrives from the factory with a bootstrap configuration. Upon initial power-on, the device automatically pulls a full initial configuration from the Cisco Networking Services configuration engine, although you can optionally arrange for this manually as well. After initial configuration, you can optionally arrange for periodic incremental (partial) configurations for synchronization purposes.
For more details on using the Cisco CNS configuration engine to automatically install the initial CNS configuration, see the Cisco CNS Configuration Engine Administrator's Guide at http://www.cisco.com/en/US/docs/net_mgmt/configuration_engine/1.3/administration/guide/ag13.html
Initial Cisco Networking Services Configuration
Initial configuration of the remote device occurs automatically when the device is initialized on the network. Optionally, you can perform this configuration manually.
Cisco Networking Services assigns the remote device a unique IP address or hostname. After resolving the IP address (using Serial Line Address Resolution Protocol (SLARP), ATM Inverse ARP (ATM InARP), or PPP protocols), the system optionally uses Domain Name System (DNS) reverse lookup to assign a hostname to the device and invokes the Cisco Networking Services agent to download the initial configuration from the Cisco Networking Services configuration engine.
Incremental Configuration
Before you can configure an incremental configuration, Cisco Networking Services must be operational and the required Cisco Networking Services agents configured.

Configuring Advanced Cisco Networking Services Features
Perform this task to configure more advanced Cisco Networking Services features. After the Cisco Networking Services agents are operational, you can configure some other features. You can enable the Cisco Networking Services inventory agent--that is, send an inventory of the device’s line cards and modules to the Cisco Networking Services configuration engine--and enter Cisco Networking Services inventory mode.
Some other advanced features allow you to use the Software Developer’s Toolkit (SDK) to specify how Cisco Networking Services notifications should be sent or how to access MIB information. Two encapsulation methods can be used: either nongranular (SNMP) encapsulation or granular (XML) encapsulation.

Troubleshooting Cisco Networking Services Agents
This section explains how to troubleshoot Cisco Networking Services agent issues.
The show commands created for the Cisco Networking Services image agent display information that is reset to zero after a successful reload of the device. Depending on the configuration of the image distribution process, the new image may not reload immediately. When a reload is not immediate or has failed, use the Cisco Networking Services image agent show commands to determine whether the image agent has connected to the image distribution server over HTTP or whether the image agent is receiving events from an application over the Cisco Networking Services Event Bus.
