Configuration Commands

Quality of Service configuration

Use the Quality of Service (QoS) commands to configure the IEEE 802.1p priority value of incoming packets. This allows you to differentiate between various types of traffic, and provide different priority levels.

QoS 802.1p configuration

This feature provides the HP 10GbE switch the capability to filter IP packets based on the IEEE 802.1p bits in the packet's VLAN header. The 802.1p bits specify the priority that you should give to the packets while forwarding them. The packets with a higher (non-zero) priority bits are given forwarding preference over packets with numerically lower priority bits value.

The following table describes the 802.1p Configuration commands. Table 154 802.1p Configuration commands

Command	Description
qos transmit-queue mapping	Maps the 802.1p priority of to the Class of Service queue (COSq)
<priority (0-7)>	priority. Enter the 802.1p priority value (0-7), followed by the Class of
<queue (0-1)(0-7)>	Service queue (0-1) that handles the matching traffic.
	Command mode: Global configuration
qos transmit-queue weight-cos	Configures the weight of the selected Class of Service queue (COSq).
<queue (0-1)(0-7)> <weight	Enter the queue number, followed by the scheduling weight (0-15).
(0-15)>	Command mode: Global configuration
qos transmit-queue	Sets the number of Class of Service queues for switch ports.
number-cos 28	The default value is 2.
	Command mode: Global configuration
default qos transmit-queue	Resets 802.1p configuration to default values.
	Command mode: Global configuration
show qos transmit-queue	Displays the current 802.1p parameters.
	Command mode: All except User EXEC
show qos transmit-queue	Displays the current 802.1p parameters, and the 802.1p priority level
information	for each port.
