interface-set (Dynamic VLAN Interface Sets Association)


Hierarchy Level


For MX Series routers with MPC/MIC modules that face the access side of the network, associate an agent circuit identifier (ACI) or access-line-identifier (ALI) interface set with a dynamic VLAN subscriber interface for DHCP or PPPoE subscribers. To associate the interface set with a dynamic subscriber interface, you must include the interface-set stanza in the dynamic profile that defines the logical subscriber interface.

An ACI or ALI interface set is a logical collection of subscriber interfaces that originate at the same household or on the same access-loop port. An ACI set is created based on the receipt only of the ACI for the subscriber access line in a DHCP or PPPoE control packet. An access-line-identifier set is created based on the receipt of a trusted option, which can be the ACI, the ARI, both these identifiers, or the absence of both these identifiers.

You specify the trigger for either interface set type at the [edit dynamic-profiles profile-name interfaces “$junos-interface-ifd-name” unit “$junos-interface-unit” auto-configure] hierarchy level. For ACI interface sets, use the agent-circuit-identifier statement. For ALI interface sets, use the line-identity statement.


  • interface-set-name—Name of the ACI interface set, which is represented in a dynamic profile for a subscriber interface by the predefined variable $junos-interface-set-name.
