Parameters
cosp Specifies the Class of Service (CoS) priority level. The
CoS priority levels are 0 through 7, with 0 as the
lowest priority and 7 as the highest. You can assign
more than one priority to an egress queue.
qid Specifies the egress queue number. The egress
queues are numbered 0 through 3, with queue 0 as
the lowest priority and 3 as the highest.
Description
This command maps CoS priorities to port egress queues. You must
specify both the priority and the queue ID. You can assign more than
one priority to an egress queue. Table 3 lists the default mappings
between the eight CoS priority levels and the four egress queues of a
switch port:
