Release Information

Statement introduced in JUNOS Release 9.0 for EX Series switches.


For EX Series switches, configure the forwarding class used to handle packets on the VoIP interface.




class—Forwarding class:

  • assured-forwarding— Assured forwarding (AF)—Provides a group of values you can define and includes four subclasses: AF1, AF2, AF3, and AF4, each with three drop probabilities: low, medium, and high.
  • best-effort—Provides no service profile. For the best effort forwarding class, loss priority is typically not carried in a class-of-service (CoS) value, and random early detection (RED) drop profiles are more aggressive.
  • expedited-forwading—Provides a low loss, low latency, low jitter, assured bandwidth, end-to-end service.
  • network-control—Provides a typically high priority because it supports protocol control.
