Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

Configure the priority-based flow control (PFC) and enhanced traffic selection (ETS) settings in a DCB map before you can apply them on downstream server-facing ports.

1. Create a DCB map to specify the PFC and ETS settings for groups of dot1p priorities. CONFIGURATION mode dcb-map name
2. Configure the PFC setting (on or off) and the ETS bandwidth percentage allocated to traffic in each priority group or whether priority group traffic should be handled with strict priority scheduling. DCB MAP mode priority-group group_num {bandwidth percentage | strict-priority} pfc {on | off}
3. Specify the priority group ID number to handle VLAN traffic for each dot1p class-of-service: 0 through 7. Leave a space between each priority group number. DCB MAP mode priority-pgid dot1p0_group-num dot1p1_group-num dot1p2_group-num dot1p3_group-num dot1p4_group-num dot1p5_group-num dot1p6_group-num dot1p7_group-num
