Setting The Priority Of Protocol Packets - H3C S3100-52P Operation Manual

Operation Manual – QoS-QoS Profile
H3C S3100-52P Ethernet Switch
between 802.1p priority and the output queues and assigning packets with different
priorities to the corresponding output queues.
Note that, this is a global setting, not a per port setting. This is only recommended for
advanced network environments.
I. Configuration prerequisites
The mapping between 802.1p priority and local precedence has been determined.
II. Configuration procedure
Follow these steps to configure the mapping between 802.1p priority and local
precedence:
Enter system view
Configure the mapping
between 802.1p
priority and local
precedence
III. Configuration example
Configure the following mapping between 802.1p priority and local precedence: 0
to 2, 1 to 3, 2 to 4, 3 to 1, 4 to 7, 5 to 0, 6 to 5, and 7 to 6.
Display the configuration.
Configuration procedure:
