A.
drop profile map

B.
behavior aggregate classifier

C.
rewrite marker

D.
multifield classifier

Explanation:
The following steps describe the CoS process:
1. A logical interface has one or more classifiers of different types applied to it.
2. The classifier assigns the packet to a forwarding class and a loss priority
3. Each forwarding class is assigned to a queue
4. Input (and output) policers meter traffic and might change the forwarding class and loss priority if a traffic
flow exceeds its service level.
5. The physical or logical interface has a scheduler map applied to it
6. The scheduler defines how traffic is treated in the output queue—for example, the transmit rate, buffer size,
priority, and drop profile
7. The scheduler map assigns a scheduler to each forwarding class (
8. The drop-profile defines how aggressively to drop packets that are using a particular scheduler
9. The rewrite rule takes effect as the packet leaves a logical interface that has a rewrite rule configured. The
rewrite rule writes information to the packet (for example, EXP or DSCP bits) according to the forwarding
class and loss priority of the packet.
