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 is used 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.
Change this mapping by specifying the 802.1p user priority users want to map
to the <class_id 0-3> (the number of the hardware queue).
<priority 0-7> - The 802.1p user priority to associate with the class_id (the
number of the hardware queue).
<class_id 0-3> - The number of the switch’s hardware priority queue. The
switch has four hardware priority queues available. They are numbered
between 0 (the lowest priority) and 3 (the highest priority).
Restrictions Only Administrator-level users can issue this command.
