To set the size of the four traffic classes that the Switch creates for outbound packets:

>set qos egressqueuesize <port_list> <class_list> <percentage>

specifies the amount of buffer memory the switch reserves in the outgoing queue for

specified ports and traffic classes

<port_list> one or more or a range of ports

<class_list> one or more traffic classes, from 0 - 3

<percentage> 0 through 100. The default is 100.

Example: >set qos egressqueuesize 2, 3 75%

To change the priority of incoming priority-tagged packets:

>set qos defaultpriority <port_list> <priority>

changes the priority tag in incoming priority-tagged packets

<port_list> one or more or a range of ports

<priority> is a value from 0-7 that sets the priority for all incoming traffic on the specified

port or ports. 0 is the lowest, 7 is the highest.

Example: >set qos defaultpriority 1, 4-8 7

To have the Switch change the priority value in incoming priority-tagged packets to a new value when the

packets leave the Switch:

>set qos regenpriority <port_list> <priority_list> <new_priority>

sets the new, regenerated priority for IP traffic. Changes the priority tag from the packets

incoming value to a new value for transit. By default, the new priority is equivalent to the

old priority.

<port_list> one or more or a range of ports

<priority_list> a list of one or more priority values, numbers from 0-7

<new_priority> the new priority level. A number from 0-3.

Example: >set qos regenpriority 1-4 0,1,2 3

The following show commands display the Switch's settings.

>show qos defaultpriority <port_list>

displays default priority (0-7) for the given list of ports

Example: >show qos defaultpriority 1-4

>show qos egressqueuesize <port_list> <class_list>

shows the outgoing data queue sizes, in percent, for the specified ports
