Quality of Service
To disable this feature, use the following command:
disable diffserv replacement port [<port_list> | all]
The default QoS profile to DiffServ code point mapping is shown in

You change the DiffServ code point mapping, using either the QoS profile or the 802.1p value, to any
code point value using the following command:
configure diffserv replacement [{qosprofile} <qosprofile> | priority <value>] code-
point <code_point>
NOTE
Extreme Networks recommends that you use the qosprofile <qosprofile> value to configure this parameter.
By doing so, the queue used to transmit a packet determines the DiffServ value replaced in the IP
packet.
To view currently configured DiffServ information, use the following command:
show diffserv [examination | replacement]
DiffServ example for the BlackDiamond 8800 family of switches and the Summit X450 switch. In this
example on the BlackDiamond 8800 family of switches and the Summit X450 switch, we use DiffServ to
signal a class of service throughput and assign any traffic coming from network 10.1.2.x with a specific
DiffServ code point. This allows all other network switches to send and observe the Diffserv code point
instead of repeating the same QoS configuration on every network switch.
