Command Description
cos set
{
sched {round-robin | strict} |
queue class <class> max
<max_packets> latency <latency> |
def-pri-tag tag <priority_tag> port
<portlist> |
pri-map pri <priority_tag> class <class>
}
Defines the Class of Service (CoS) parameters for
CoS queues (0-3)
Type one of the following in the command:
• sched {round-robin | strict}—Sets 802.1p
CoS queue forwarding option. Type sched
and one of the following scheduling options:
• round-robin—Forwarding starts with the
packets in the highest priority queue,
moves to the queue with the next highest
priority, and continues through to the
queue with the lowest priority. At that

with the highest priority.
• strict—When the highest priority queue
is full, those packets are the first to be

• class <class>—Sets the CoS queue.
Type class and a value from 0 to 3.

• latency <latency>—Sets the maximum
latency/time (in seconds) allowable for a
packet to stay in the CoS queue. Type
latency and a value from 0 to 255.
• def-pri-tag—Defines the default CoS priority-
tag values (0-7) for the incoming non-priority
tagged frames for a port or ports. Type
def-pri-tag and the following:
• tag <priority_tag>—Type tag and a value
from 0 to 7.
• port <portlist>—Type port and the port
number or series of port numbers.
• pri-map—Set the mappings for priority tags to
the CoS queue. Type pri-map and the
