Forwarding Class

Names of forwarding classes assigned to queue
numbers. By default, the following forwarding classes are assigned
to queues 0, 1, 5, or 7:
-
best-effort—Provides no special CoS handling
of packets. Loss priority is typically not carried in a CoS value.
-
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.
