stacked-interface-set (Dynamic Profiles)


Hierarchy Level


For MX Series routers with MPCs that support 5-level hierarchical scheduling, define an interface set over interface set hierarchy. The child interface set (L3) contains subscriber logical interfaces, and the parent interface set (L2) contains one or more interface sets as members.


For both interface-sets in the stack (at L3 and L2), a CoS traffic-control-profile (TCP) must be assigned to each.


interface-set-name—Name of the interface set to be configured or one of the following Junos OS predefined variables:

  • $junos-aggregation-interface-set-name—L2 interface-set representing a logical intermediate node (DPU-C or PON tree) in the access network.

  • $junos-default-interface-set-name—An intermediate, default variable used to resolve the L3 (child) interface-set name based on whether subscriber access is via a logical intermediate aggregation node

  • $junos-interface-set-name—Predefined variable that, when used, is replaced with the interface-set obtained from the RADIUS server when a subscriber authenticates over the interface to which the dynamic profile is attached.

  • $junos-phy-ifd-underlying-intf-set-name—A default, topology-based interface-set derived from the predefined variable, $junos-phy-ifd-underlying-intf-set-name by appending “-underlying” to conserve L2 CoS nodes. It is a variation of the $junos-phy-ifd-interface-set-name variable used as a default L2 interface-set for 4-level hierarchy or default L3 interface-set for 5-level hierarchy.
