RoCE Configuration for MLNX-OS Based Switches without Setting QoS

Version 14

    This post provides a configuration example for Mellanox Spectrum installed with MLNX-OS and running RoCE over a lossy network, assuming QoS is not set.



    Step 1 - Enable ECN Marking

    Note - When no QoS is configured on the switch, all traffic will be mapped to priority 0 and traffic class 0 by default.

    switch (config) # interface ethernet 1/1-1/32 traffic-class 0 congestion-control ecn minimum-absolute 150 maximum-absolute 1500
