qos map {dot1p_to_tc|dscp_to_tc|tc_to_queue}

[Command] qos map {dot1p_to_tc|dscp_to_tc|tc_to_queue} profile_name pri_origin pri_mapped

[Purpose] Add QoS mapping table template

[Parameter]

Parameter	Description
dot1p_to_tc	Mapping of 802.1P priority of packet to internal priority
tc_to_queue	Mapping the priority of packet to the egress queue
profile_name	Qos_map name
pri_origin	Pre-mapping priority
pri_mapped	Priority after mapping

[View] System configuration view

[User Scenario] If user need to prioritize packets received by a device based on the dot1p/DSCP values carried in the packet for QoS scheduling, user can configure the mapping of packet priorities to local priorities using the qos map {dot1p_to_tc|dscp_to_tc} <profile_name> <in_value> command. The qos map tc_to_queue <profile_name> <in_value> command configures the mapping of local priorities to output queues, allowing you to implement different QoS strategies based on different scheduling methods for the output queues.

[Notes] By default, the local priority is mapped to the queue is:

tc	queue
0	0
1	1
2	2
3	3
4	4
5	5
6	6
7	7

[Use Cases]

sonic(config)# qos map tc_to_queue queue 0 0
sonic(config)# qos map tc_to_queue queue 1 1

sonic(config)# qos map tc_to_queue queue 4 4
sonic(config)# qos map tc_to_queue queue 5 5
sonic(config)# qos map tc_to_queue queue 6 6
sonic(config)# qos map tc_to_queue queue 7 7
