xStack DGS-3612G Layer 3 Gigabit Ethernet Managed Switch CLI Manual
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 0-7>
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 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 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-level users can issue this command.
Example usage:
To configure 802.1 user priority on the Switch:
DGS-3612G:4# config 802.1p user_priority 1 7
Command: config 802.1p user_priority 1 7
Success.
DGS-3612G:4#
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.
