Attributes

Accepted as keyword arguments of .function_node(name) and of .set(**attrs) on this cursor. Enum parameters also accept the plain string.

parameter	wire	type	values	default	description
name (positional)	name	str	—	—	The name of the abstract node.
description	descr	str	—	—	Specifies a description of the policy definition.
func_template_type	funcTemplateType	VnsFuncTemplateType	ADC_ONE_ARM, ADC_TWO_ARM, CLOUD_NATIVE_FW, CLOUD_NATIVE_LB, CLOUD_VENDOR_FW, CLOUD_VENDOR_LB, FW_ROUTED, FW_TRANS, OTHER	OTHER	Func Template type
function_type	funcType	VnsNodeFuncType	GoThrough, GoTo, L1, L2, None	GoTo	A function type. A GoThrough node is a transparent device, where a packet goes through without being addressed to the device, and the endpoints are not aware of that device. A GoTo device has a specific destination.
is_copy	isCopy	bool	—	False	if the device is a copy device
managed	managed	bool	—	True	Specified if the function is using a managed device
owner_key	ownerKey	str	—	—	The key for enabling clients to own their data for entity correlation.
owner_tag	ownerTag	str	—	—	A tag for enabling clients to add their own data. For example, to indicate who created this object.
routing_mode	routingMode	VnsRoutingMode	Redirect, unspecified	unspecified	—
sequence_number	sequenceNumber	int	—	0	Sequence number. For CLI purposes
share_encap	shareEncap	bool	—	False	—

APIC diagnostics

States the APIC can flag on this class — it accepts the configuration and reports the inconsistency afterwards.
