DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Switch CLI Reference Manual
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 allows users 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 0-3> (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.
Example usage:
To configure 802.1 user priority on the Switch:
DES-3028P:4# config 802.1p user_priority 1 3
Command: config 802.1p user_priority 1 3
Success.
DES-3028P: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 four 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 four hardware priority queues.
Parameters None.
Restrictions None.
