tenant.bd.subnet

A subnet defines the IP address range that can be used within the bridge domain. While a context defines a unique layer 3 space, that space can consist of multiple subnets. These subnets are defined per bridge domain.

Attributes

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

parameter	wire	type	values	default	description
subnet (positional)	ip	str	—	—	The IP address and mask of the default gateway.
subnet_control	ctrl	FvSubnetControl	unspecified, querier, nd, no-default-gateway	nd	The subnet control state. The control can be specific protocols applied to the subnet such as IGMP Snooping.
description	descr	str	—	—	Specifies the description of a policy component.
ip_dp_learning	ipDPLearning	FvipDPLearning	disabled, enabled	enabled	Knob to disable IP Dataplane Learning for Host(/32, /128) and for BD Subnet
name	name	str	—	—	—
preferred	preferred	bool	—	False	Indicates if the subnet is preferred (primary) over the available alternatives. Only one preferred subnet is allowed.
scope	scope	FvRouteScp	public, private, shared	private	The network visibility of the subnet.
virtual	virtual	bool	—	False	Treated as virtual IP address. Used in case of BD extended to multiple sites.

APIC diagnostics

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

Config issues

code	meaning
multiple-tag-selector-match	Tag(s) matching more than one ESG TagSelector. Subnets can only be associated to a single ESG TagSelector via Tags.
multiple-tag-selector-match-after-single-match	Tag(s) are now matching more than one ESG TagSelector. The original match is still active. Subnets can only be associated to a single ESG TagSelector via Tags.
