Quality Of Service Configuration; Qos 802.1P Configuration - HP 445860-B21 - 10Gb Ethernet BL-c Switch Reference Manual

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.

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