Cisco Networking Services Enhanced Results Message

The Cisco Networking Services Enhanced Results Message feature sends a second Cisco Networking Services result message to the subject “cisco.cns.config.results” in addition to the Cisco Networking Services results messages sent to the Cisco Networking Services Event bus after a partial configuration is complete.

The Cisco Networking Services enhanced results 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.

Information About Cisco Networking Services Enhanced Results Message

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.

    7.    exit


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Device> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.

     
    Step 2 configure terminal


    Example:
    Device# configure terminal
     

    Enters global configuration mode.

     
    Step 3 cns config partial {host-name | ip-address} [encrypt] [port-number] [source interface name] [inventory]


    Example:
    Device(config)# cns config partial 172.28.129.22 80
     

    (Optional) Starts the Cisco Networking Services configuration agent, which provides Cisco Networking Services configuration services to Cisco clients, and initiates an incremental (partial) configuration.

    • Use the optional port-number argument to specify the port number for the configuration server. The default is 80.

    • Use the optional source keyword and ip-address argument to specify the use of an IP address as the source for Cisco Networking Services configuration agent communications.

    • Use the optional inventory keyword to send an inventory of the linecards and modules in the device to the Cisco Networking Services configuration engine as part of the HTTP request.

    Note   

    The optional encrypt keyword is available only in images that support SSL.

     
    Step 4 logging cns-events [severity-level]


    Example:
    Device(config)# logging cns-events 2
     

    (Optional) Enables XML-formatted system event message logging to be sent through the Cisco Networking Services event bus.

    • Use the optional severity-level argument to specify the number or name of the desired severity level at which messages should be logged. The default is level 7 (debugging).

     
    Step 5 cns exec [encrypt] [port-number] [source {ip-address | interface-type-number}]


    Example:
    Device(config)# cns exec source 172.17.2.2
     

    (Optional) Enables and configures the Cisco Networking Services EXEC agent, which provides Cisco Networking Services EXEC services to Cisco clients.

    • Use the optional port-number argument to specify the port number for the EXEC server. The default is 80.

    • Use the optional source keyword and ip-address/interface-type number argument to specify the use of an IP address as the source for Cisco Networking Services EXEC agent communications.

    Note   

    The optional encrypt keyword is available only in images that support SSL.

     
    Step 6 cns event {hostname | ip-address} [encrypt] [port-number] [backup] [failover-time seconds] [keepalive seconds retry-count] [source ip-address | interface-name][clock-timeout time] [reconnect-time time]


    Example:
    Device(config)# cns event 172.28.129.22 source 172.22.2.1
     

    Configures the Cisco Networking Services event gateway, which provides Cisco Networking Services event services to Cisco clients.

    • The optional encrypt keyword is available only in images that support SSL.

    • Use the optional port-number argument to specify the port number for the event server. The default is 11011 with no encryption and 11012 with encryption.

    • Use the optional backup keyword to indicate that this is the backup gateway. Before configuring a backup gateway, ensure that a primary gateway is configured.

    • Use the optional failover-time keyword and seconds argument to specify a time interval in seconds to wait for the primary gateway route after the route to the backup gateway is established.

    • Use the optional keepalive keyword with the seconds and retry-count arguments to specify the keepalive timeout in seconds and the retry count.

    • Use the optional source keyword and ip-address/interface-name argument to specify the use of an IP address as the source for Cisco Networking Services event agent communications.

    • Use the optional clock-timeout keyword to specify the maximum time, in minutes, that the Cisco Networking Services event agent will wait for the clock to be set for transports (such as SSL) that require an accurate clock.

    • Use the optional reconnect-time keyword to specify the configurable upper limit of the maximum retry timeout.

    Note   

    Until the cns event command is entered, no transport connections to the Cisco Networking Services event bus are made and therefore no other Cisco Networking Services agents are operational.

     
    Step 7 exit


    Example:
    Device(config)# exit
     

    Exits global configuration mode and returns to privileged EXEC mode.

     

    Troubleshooting Tips

    • Use the show cns event connections command to check that the Cisco Networking Services event agent is connected to the Cisco Networking Services event gateway.

    • Use the show cns event subject command to check that the image agent subject names are registered. Subject names for the Cisco Networking Services image agent begin with cisco.mgmt.cns.image.

    Configuration Examples for Cisco Networking Services Enhanced Results Message

    Example: Configuring a Partial Configuration

    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.

    The following example shows incremental (partial) configuration on a remote device. The Cisco Networking Services configuration engine IP address is 172.28.129.22, and the port number is 80. 

     cns config partial 172.28.129.22 80
