Description
An interface represents a network interface belonging to one network device. An interface may be a physical port, a BSSID carried on a wireless access point, or other layer-2 attachments. An interface may have several simultaneous names including a link-layer address that is unique on any VLAN. An interface may carry traffic for one untagged VLAN and several tagged VLANs.
Parameter prefix: ifc
Relationships
device
Related type: device
Description: The singular parent device to which
the interface belongs; a reference to the device described by the
"device_name" and "device_id" essential attributes
Dressing parameter: ifc_device
Cardinality: exactly one (scalar)
Relationship Attribute: interface.device_id
Availability restricted to: This topic/item has not yet been finalized.
untagged_vlans
Related type: interface_vlan
Description: The set of interface_vlan objects
representing a vlan configuration on the interface for which the
interface carries traffic without 802.1q frame tags.
Dressing parameter: ifc_untagged_vlans
Cardinality: zero to many (list)
Relationship Attribute: interface_vlan.interface_id
Availability restricted to: This topic/item has not yet been finalized.
tagged_vlans
Related type: interface_vlan
Description: The set of interface_vlan objects
representing a vlan configuration on the interface for which the
interface carries traffic with 802.1q frame tags.

Relationship Attribute: interface_vlan.interface_id
Availability restricted to: This topic/item has not yet been finalized.
vlans
Related type: interface_vlan

observed_macs
Related type: mac_port
Description: The set of mac_port objects, which are
intervals of MAC address appearances, observed on the interface during
the query time frame
Dressing parameter: ifc_observed_macs
Cardinality: zero to many (list)
Relationship Attribute: mac_port.interface_id
