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
|

classes.
