Synopsis

• Configuring LAN Automation sessions in Cisco Catalyst Center for automated discovery of devices and their integration into the network.

• Updating LAN Automation device configurations, including loopback addresses, hostnames, and link configurations.

• Automatically stopping an ongoing LAN Automation session based on conditions like timeout or discovery device list completion, without explicitly calling the stop API.

• Additionally, it provides functionalities to stop ongoing LAN Automation sessions and to handle PnP device authorization.

Requirements

The below requirements are needed on the host that executes this module.

• dnacentersdk >= 2.9.2

• python >= 3.9

Parameters

Parameter	Comments

destination_device_management_ip_address string / required	Management IP address of the destination device.
ip_pool_name string / required	Name of the IP pool configured within LAN Automation, from which IP addresses will be allocated for the new link.
source_device_interface_name string / required	Interface name on the source device.
source_device_management_ip_address string / required	Management IP address of the source device.
link_delete dictionary	Remove an existing link between two devices.
destination_device_interface_name string / required	Interface name on the destination device.
destination_device_management_ip_address string / required	Management IP address of the destination device.
source_device_interface_name string / required	Interface name on the source device.

loopback_update_device_list list / elements=dictionary	List of devices to update with new loopback IP addresses.
device_management_ip_address string / required	Management IP address of the device.
new_loopback0_ip_address string / required	New Loopback0 IP Address for the device, sourced from the LAN pool associated with the device discovery site.
lan_automation dictionary	Configuration for starting or stopping LAN Automation sessions.
device_serial_number_authorization list / elements=string	A list of serial numbers of devices to be authorized during the session.
discovered_device_site_name_hierarchy string / required	Site hierarchy where the discovered devices will be placed.
discovery_devices list / elements=dictionary	A list of devices to be discovered during the LAN Automation session. If only a device list is provided without a timeout, stop processing will occur once all devices from the list are discovered. The maximum number of devices that can be provided for a session is 50. If both the discovery devices list and timeout are provided, the stop processing will be attempted whichever happens earlier. Users may choose to use the LAN Automation ‘deleted’ state to stop processing at any time.
device_host_name string	Hostname of the device to be discovered.
device_management_ip_address string	Management IP address of the device.
device_serial_number string / required	Serial number of the device to be discovered.
device_site_name_hierarchy string	Site hierarchy where the device will be placed after discovery.
discovery_level integer	Depth of the discovery during LAN automation (e.g., Level 1-5 below the primary seed device). Default: 2
discovery_timeout integer	Timeout for device discovery during LAN Automation, in minutes. Until this time, stop processing will not be triggered. Any device contacting after the provided discovery timeout will not be processed, and a device reset and reload will be attempted to bring it back to the PnP agent state before process completion. The supported timeout range is in minutes [20-10080]. If both ‘discovery_timeout’ and ‘discovery_devices’ are provided, processing will stop based on whichever occurs earlier. Users can always use the LAN Automation deleted state to force stop processing.
host_name_prefix string	Prefix used for auto-generating hostnames during the LAN Automation session.
ip_pools list / elements=dictionary / required	A list of IP pools used during the LAN Automation session.
ip_pool_name string / required	Name of the IP pool.
ip_pool_role string / required	Role of the IP pool in the automation session, either MAIN_POOL or PHYSICAL_LINK_POOL. Choices: "MAIN_POOL" "PHYSICAL_LINK_POOL"
isis_domain_pwd string	Password for IS-IS domain configuration.
launch_and_wait boolean	Flag indicating whether the task should pause until the LAN Automation session completes before continuing to subsequent tasks. If set to false, the process will move to the next task immediately. Choices: false ← (default) true
multicast_enabled boolean	Flag to enable multicast routing in the LAN Automation session. Choices: false ← (default) true
peer_device_management_ip_address string	Management IP address of the peer device in the LAN Automation session.
pnp_authorization boolean	Flag to enable Plug and Play (PnP) authorization for devices discovered during the session. Choices: false ← (default) true
primary_device_interface_names list / elements=string / required	A list of interface names on the primary device to be used for LAN automation.
primary_device_management_ip_address string / required	Management IP address of the primary or seed device in the LAN Automation session.

When true and dnac_log_file_path is not provided, - Create the log file at the execution location with the name ‘dnac.log’. When false, - Logging is disabled. If the log file doesn’t exist, - It is created in append or write mode based on the “dnac_log_append” flag. If the log file exists, - It is overwritten or appended based on the “dnac_log_append” flag. Choices: false ← (default) true
dnac_log_append boolean	Determines the mode of the file. Set to True for ‘append’ mode. Set to False for ‘write’ mode. Choices: false true ← (default)

Notes

Note

• When waiting for the LAN automation session to complete, the timeout and the list of devices to be discovered will initially be considered. If neither a timeout nor a device list is provided, LAN automation will continue running until stopped.

• To stop a LAN automation session, execute the same details in the ‘deleted’ state. Only the seed device IP is required to terminate the session.

• PnP authorization will be performed if device authorization has been selected in Catalyst Center. LAN automation will continue running until the provided serial numbers are authorized, continuously checking the status of the devices. If PnP authorization is enabled without a list of devices for either authorization or discovery, the module will not wait for the LAN automation task to complete. However, if a device is in an Error state or authorization is not checked on Catalyst Center, the playbook will keep running until the state of the device is active or reached the timeout value.

• Does not support check_mode

• The plugin runs on the control node and does not use any ansible connection plugins instead embedded connection manager from Cisco Catalyst Center SDK

• The parameters starting with dnac_ are used by the Cisco Catalyst Center Python SDK to establish the connection
