config 802.1p user_priority
Purpose
Used to map the 802.1p user priority of an incoming packet to one of
the four hardware queues available on the switch.
Syntax
config 802.1p user_priority <priority 0-7> <class_id 0-3>
Description
This command allows you to configure the way the switch will map
an incoming packet, based on its 802.1p user priority, to one of the
four available hardware priority queues on the switch.
The switch’s default is to map the following incoming 802.1p user
priority values to the four hardware priority queues:
802.1p Hardware Queue Remark
0 1 Mid-low
1 0 Lowest
2 0 Lowest
3 1 Mid-low
4 2 Mid-high
5 2 Mid-high
6 3 Highest
7 3 Highest.
This mapping scheme is based upon recommendations contained in
IEEE 802.1D.
You can change this mapping by specifying the 802.1p user priority
you want to go to the <class_id 0-3> (the number of the hardware
