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 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.

Command
Description
qos transmit-queue mapping
<
priority (0-7)
> <
queue (0-1)
>
Maps the 802.1p priority to the Class of Service queue (COSq). 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
qos transmit-queue weight-cos
<
queue (0-1)
> <
weight (0-15)
>
Configures the weight of the selected Class of Service queue (COSq).
Enter the queue number (0-1), followed by the scheduling weight (0-15).
