priority queue for all ports, use the set qos map command.
set qos map port_type tx | rx q# thr# cos coslist
set qos map port_type tx | rx q# cos coslist
Syntax Description
Defaults The default mappings for all ports are shown in Tabl e 2-20 and Table 2- 21.
port_type Port type; valid values are 2q2t, 1p2q2t, 1p3q1t, and 1p2q1t for transmit.
Valid values are 1q2t, 1p1q4t, 1p1q0t, and 1p1q8t, 2q8t for receive. See the

priority queue.
thr# Value determined by the number of drop thresholds available at a port; valid
values are 1 and 2, with the higher value indicating lower chances of being
dropped.
cos coslist Specifies CoS values; valid values are from 0 through 7, with the higher
numbers representing a higher priority.
