NCM Config Transfer

Config Transfers

Network Configuration Manager 7.4 (released in 2015) introduced a new API for managing configuration transfer operations, including downloading device configs, uploading device configs, and executing scripts on devices. This API consists of a set of verbs on the existing Cirrus.ConfigArchive entity type and a new NCM.TransferResults entity type you can query to check on the status of config transfer operations.

Cirrus.ConfigArchive

Verb: DownloadConfig

Download configs for multiple devices and store them in NCM database.

Guid[] DownloadConfig(Guid[] nodeId, string configType)

• nodeId - list of NCM node Ids to download configs from
• ConfigType - Config Type to download

Returns a list of TransferID values, one per specified node. Query NCM.TransferResults with these TransferID values to track the status of the operations.

Verb: UploadConfig

Upload config changes for multiple devices.

Guid[] UploadConfig(Guid[] nodeId, string configType, string ConfigText, bool RebootDevice)

• nodeId - list of NCM node Ids to upload config changes to
• ConfigType - Config Type to upload
• ConfigText - config text to upload
• RebootDevice - true to reboot the device after uploading the new config

Returns a list of TransferID values, one per specified node. Query NCM.TransferResults with these TransferID values to track the status of the operations.

Verb: ExecuteScript

Execute script on multiple devices

Guid[] ExecuteScript(Guid[] nodeId, string script)

Run a script (specified as a string in the script parameter) on each of the nodes (specified by NCM NodeID GUID in the nodeId parameter). Returns a list of TransferID values, one per specified node. Query NCM.TransferResults with these TransferID values to track the status of the operations.

Verb: ClearTransfers

void ClearTransfers(Guid[] TransferTickets)

Remove the history record from NCM.TransferResults for the transfers with the TransferID values specified in TransferTickets. No return value.

Verb: CancelTransfers

void CancelTransfers(Guid[] TransferTickets)

Cancel any ongoing or queued transfers with the TransferID values specified in TransferTickets. No return value.

NCM.TransferResults

Query NCM.TransferResults to see the status of queued and completed config transfer operations.

• TransferID - unique ID of transfer ticket returned to client by one of transfer verbs
• NodeId - NCM Node Id from NCM.NodeProperties entity
• Action - enum type of transfer: Download = 1, Upload = 2, Execute Script = 3
• RequestedConfigType - originally requested type of config to perform transfer. Value is NULL for execute script action
• RequestedScript - Original script requested to execute on device. Value is NULL for download config action

• TransferProtocol - textual description of protocols combination used to perform transfer (for example Telnet - TFTP)
• Status - enum status of transfer: Queued = 0 - means transfer is waiting for execution in queue, Transferring = 1 - means transfer is executing right now, Complete = 2, Error = 3
• ErrorMessage - transfer error message. Value is populating only in case Status is equal to Error
• DeviceOutput - store script execution results. Value is empty for download config action
• DateTime - time when transfer was requested
• UserName - name of user who requested transfer
