- Why I did it
Recently buffer configuration has been updated:
dynamic_thof profiles used for BUFFER_PORT_INGRESS_PROFILE_LIST/BUFFER_PORT_EGRESS_PROFILE_LIST which represent per port ingress/egress reserved buffer respectively.This update is applied to all Mellanox platforms and SKUs. It is enforced by the
db_migratorwhich will check the buffer configuration after a switch undergoes a SONiC-to-SONiC upgrade from an old image to a new one. If the buffer configuration matches the default value it will be upgraded to the new one. The granularity of matching is:It depends on sonic-utilities PR #993 which includes the
db_migratorpart.- How I did it
- How to verify it
