Release 17.2R2 New and Changed Features

There are no new features or enhancements to existing features for Junos Fusion Provider Edge in Junos OS Release 17.2R2.

Release 17.2R1 New and Changed Features

Class of Service (CoS)

  • Per-unit scheduler support on extended ports (Junos Fusion Provider Edge)—Beginning with Junos OS 17.2R1, Junos Fusion Provider Edge supports per-unit schedulers on extended ports. To support per-unit scheduling on an extended port, all cascade ports on the aggregation device for that extended port must have a queueing chip. aggregated Ethernet ports support per-unit schedulers, but all aggregated Ethernet member ports must be on the same satellite device. To enable per-unit scheduling on an extended port, enable the per-unit-scheduler option at the [edit interfaces interface-name] hierarchy level for the extended port.

  • Hierarchical CoS support on extended ports (Junos Fusion Provider Edge)—Beginning with Junos OS 17.2R1, Junos Fusion Provider Edge supports hierarchical CoS (interface set-level scheduling) on extended ports. To support hierarchical CoS on an extended port, all cascade ports on the aggregation device for that extended port must have a queueing chip. aggregated Ethernet ports support hierarchical schedulers, but all aggregated Ethernet member ports must be on the same satellite device. To enable hierarchical CoS on an extended port, enable the hierarchical-scheduler option at the [edit interfaces interface-name] hierarchy level for the extended port.

Junos Fusion

  • Support for selective VLAN local switching—Starting in Junos OS Release 17.2R1, Junos Fusion Provider Edge supports local switching on a service level. When you configure selective VLAN local switching on satellite devices, the other VLANs will continue to follow the default forwarding behavior. Use the selective-vlan-switching option for the routing instance at the [edit forwarding-options satellite fpc slot] hierarchy level to enable selective VLAN local switching for a particular satellite device.

  • Support for an ingress policer—Starting in Junos OS Release 17.2R1, Junos Fusion Provider Edge supports the use of an ingress policer to filter incoming traffic at the extended port level. This feature supports a two-color policer that allows you to limit the traffic that is received on an interface. You can configure the Layer 2 ingress policer by using the input-policer statement at the [edit interfaces interface-name layer2-policer] hierarchy level.
