Forwarding Class

Names of forwarding classes assigned to queue numbers. By default, the following forwarding classes are assigned to queues 0 through 3:

  • best-effort—Provides no special CoS handling of packets. Loss priority is typically not carried in a CoS value, and RED drop profiles are more aggressive.

  • expedited-forwarding—Provides low loss, low delay, low jitter, assured bandwidth, and end-to-end service.

  • assured-forwarding—Provides high assurance for packets within specified service profile. Excess packets are dropped.

  • network-control—Packets can be delayed but not dropped.


Queue number corresponding to the forwarding class name.

By default, four queues, 0 through 3, are assigned to forwarding classes.
