WebRoCEv2 congestion management uses RFC 3168 to signal congestion experienced to the receiver. The receiver generates an RoCEv2 congestion notification packet directed to the source of the packet. To configure RoCE with ECN: cumulus@switch:~$ nv set qos roce mode lossy cumulus@switch:~$ nv config apply Remove RoCE Configuration WebRCM (RoCEv2 Congestion Management): Provides the capability to try to avoid congestion hot spots and try to optimize the throughput of the fabric. Resilient RoCE with ECN: RoCE is InfiniBand over UDP/IP, but ECN works with TCP/IP with the switch/router setting ECN bits and the receiving station sending a TCP/IP congestion message back
