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

• DCBx operation on an ETS port goes down.
• New ETS configurations are ignored and existing ETS configurations are reset to the previously configured ETS output policy on the port or to the default ETS settings if no ETS output policy was previously applied.

• In the CEE version, the priority group/traffic class group (TCG) ID 15 represents a non-ETS priority group. Any priority group configured with a scheduler type is treated as a strict-priority group and is given the priority-group (TCG) ID 15.
• The CIN version supports two types of strict-priority scheduling:
  • Group strict priority: Use this to increase its bandwidth usage to the bandwidth total of the priority group and allow a single priority flow in a priority group. A single flow in a group can use all the bandwidth allocated to the group.
  • Link strict priority: Use this to increase to the maximum link bandwidth and allow a flow in any priority group.

If you configure only the priority group in an ETS output policy or only the dot1p priority for strict-priority scheduling, the flow is handled with group strict priority.
