Description
Use the 
qos cos-local-precedence-map
 command to configure “CoS  
Local-precedence” mapping table. This will map a CoS value to a specific local 
precedence (queue). Note that traffic which has been assigned a local precedence 
via QOS will also be assigned to the same queue. 
Use the 
undo qos cos-local-precedence-map
 command to restore its default 
values. 
The following is the default CoS and Local Precedence table.
