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 <priority 0-7> <class_id 0-6>
Description
This command allows users to configure the method that 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 eight 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 7 Highest.
This mapping scheme is based upon recommendations contained in IEEE
802.1D.
Change this mapping by specifying the 802.1p user priority to go to the
<class_id 0-6>
(the number of the hardware queue).
<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-level users can issue this command.
Example usage:
To configure 802.1 user priority on the Switch:
DGS-3627:5#config 802.1p user_priority 1 6
Command: config 802.1p user_priority 1 6
Success.
DGS-3627:5#
show 802.1p user_priority
Purpose
Used to display the current mapping between an incoming packet’s 802.1p
priority value and one of the Switch’s seven hardware priority queues.
Syntax
show 802.1p user_priority
Description The
show 802.1p user_priority
command displays the current mapping of
an incoming packet’s 802.1p priority value to one of the Switch’s seven
hardware priority queues.
Parameters None.
Restrictions None.
