config 802.1p user_priority
Purpose
Used to map the 802.1p user priority of an incoming packet to one of the seven hardware
queues available on the Switch.
Syntax
config 802.1p user_priority {ports [<portlist> | all ]} <priority 0-7> <class_id 0-6>
Description
This command allows users to configure the way the Switch will map an incoming packet,
based on its 802.1p user priority, to one of the seven available hardware priority queues on
the Switch.
The Switch’s default is to map the following incoming 802.1p user priority values to the seven
hardware priority queues:
802.1p Hardware Queue Remark
0 2 Mid-low
1 0 Lowest
2 1 Lowest
3 3 Mid-low
4 4 Mid-high
5 5 Mid-high
6 6 Highest
7 6 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 0-6>
(the number of the hardware queue).
Parameters
[<portlist> | all]
– Specifes a range of ports to be configured.
All
specifies all ports.
<priority 0-7>
−
The 802.1p user priority to associate with the
<class_id 0-6>
(the number of
the hardware queue).
<class_id 0-6>
−
The number of the Switch’s hardware priority queue. The Switch has seven
hardware priority queues available. They are numbered between 0 (the lowest priority) and 6
(the highest priority).
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command.
Example usage:
To configure 802.1p user priority on the Switch:
DES-3528:admin# config 802.1p user_priority ports 1 5 5
Command: config 802.1p user_priority ports 1 5 5
Success.
