cos0-map-drop-prec: Mapping value from CoS 0 to drop precedence, in the range 
of 0 to 2.

cos1-map-drop-prec: Mapping value from CoS 1 to drop precedence, in the range 
of 0 to 2.

cos2-map-drop-prec: Mapping value from CoS 2 to drop precedence, in the range 
of 0 to 2.

cos3-map-drop-prec: Mapping value from CoS 3 to drop precedence, in the range 
of 0 to 2.

cos4-map-drop-prec: Mapping value from CoS 4 to drop precedence, in the range 
of 0 to 2.

cos5-map-drop-prec: Mapping value from CoS 5 to drop precedence, in the range 
of 0 to 2.

cos6-map-drop-prec: Mapping value from CoS 6 to drop precedence, in the range 
of 0 to 2.

cos7-map-drop-prec: Mapping value from CoS 7 to drop precedence, in the range 
of 0 to 2.

Use the qos cos-drop-precedence-map command to configure the "CoS -> 
Drop-precedence" mapping table.

Use the undo qos cos-drop-precedence-map command to restore the default 
values of the "CoS -> Drop-precedence" mapping table.

The system provides "CoS -> Drop-precedence" mapping table as the default 
value.

After receiving a packet, the switch allocates a set of service parameters to it 
according to a specific rule. The service parameters, including CoS value, local 
precedence and drop level, are determined according to the packet 802.1p priority 
value. CoS value is the packet 802.1p priority value, while local and drop 
precedence values are obtained according to the "CoS -> Local-precedence"
