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 is used 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.
Users may change this mapping by specifying the 802.1p user priority you want to go to
the
<class_id 0–6>
(the number of the hardware queue).
Parameters
<priority 0–7>
−
The 802.1p user priority you want to associate with the
<class_id 0–6>
(the number of the hardware queue) with.
<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:
