DSCP_TO_TC_MAP is already used by qos_config.j2.
If the intention is to use the same mapping, no need to add here. QoS config generation will create the config for DSCP_TO_TC_MAP. Having in two places will result in race condition where the last config generation will overwrite the DSCP_TO_TC_MAP.

It's a mistake I've made while updating the dscp mapping to cover all 64 associations. CBF has to have its own separate mapping. I've updated it to DSCP_TO_FC_MAP, as it should be.

can you please provide what does FC and CBF stands for ? |
Ok, I think we are referring Forwarding Class and Class Based Forwarding. Bit this create confusion what is the difference between TC and FC ? |
|
@abdosi FC allows traffic engineering as described in https://github.com/Azure/SONiC/pull/796/files while TC allows splitting packets in queues for QoS |

@Cosmin-Jinga-MS Going forward we required all configs to have a corresponding yang model. (e.g. PR for QoS #7375 ) Changes look good to me. When do you think you can create a yang model PR for: |
@Cosmin-Jinga-MS Created #9108 Can you assign this to yourself. |

is the same as DSCP_TO_TC_MAP, or do they need to be same?

The mappings used for CBF are different from the ones used in QoS. It's intended we have a separate table in this case;
DSCP_TO_TC_MAP for qos
DSCP_TO_FC_MAP for cbf

[build_templates]: Added default configuration file for CBF
[rules]: Added loading rule for CBF config
Why I did it
The CBF default config is required to load default start-up config on CBF capable platforms
How I did it
Added the default config files among the existing ones, mirroring the QOS implementation
Unit tests are in:
sonic-net/sonic-utilities#1799
How to verify it
Deploy SBI on a CBF capable platform(e.g. SODA)
Description for the changelog
Default CBF config files
