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 2-19 and Table 2- 20.
port_type Port type; valid values are 2q2t, 1p2q2t, 1p3q1t, and 1p2q1t for transmit and
1q2t, 1p1q4t, 1p1q0t, and 1p1q8t, 2q8t for receive. See the “Usage

values are 1and 2, with the higher value indicating lower chances of bei ng
dropped.
cos coslist Specifies CoS values; valid values are from 0 through 7, with the higher
numbers representing a higher priority.
