Signed-off-by: bingwang <bingwang@microsoft.com> Why I did it This PR is to add two extra lossless queues for bounced back traffic. HLD sonic-net/SONiC#950 SKUs include Arista-7050CX3-32S-C32 Arista-7050CX3-32S-D48C8 Arista-7260CX3-D108C8 Arista-7260CX3-C64 Arista-7260CX3-Q64 How I did it Update the buffers.json.j2 template and buffers_config.j2 template to generate new BUFFER_QUEUE table. For T1 devices, queue 2 and queue 6 are set as lossless queues on T0 facing ports. For T0 devices, queue 2 and queue 6 are set as lossless queues on T1 facing ports. Queue 7 is added as a new lossy queue as DSCP 48 is mapped to TC 7, and then mapped into Queue 7 How to verify it Verified by UT Verified by coping the new template and generate buffer config with sonic-cfggen |
