In order to configure RoCE on a Cumulus switch, which command should be used?

Show Suggested Answer Hide Answer
Suggested Answer: A

To enable RDMA over Converged Ethernet (RoCE) on a Cumulus switch, the correct command is:

nv set qos roce enable on

This command configures the Quality of Service (QoS) settings to support RoCE, ensuring that the necessary parameters for lossless Ethernet are applied.

I’m a bit confused; I thought "roce" had to come before "qos" in the command, but I can't recall the exact syntax.

I practiced a similar question last week, and I feel like the command started with "nv set."

I think I remember something about enabling RoCE with a command that has "qos" in it, but I'm not sure which one.
