Configuration Guide for RDMA Use Cases
Option A: PCP PFC - Set Priorities for Drop or No-drop
If setting PCP PFC, the PFC component of DCB enables drop or no-drop settings for each priority.
- When PFC is enabled, the priority is considered no-drop, or loss-less.
- When PFC is disabled, the priority is considered drop, or lossy.
If an adapter is in non-willing mode, use lldptool-V PFC. Otherwise, configure these mappings on the switch.
