Currently, I’m configuring RoCEv2 with SX1036 and ConnectX6-Dx.
I received the commands below from the switch seller for enabling OEM (open ethernet mode) MODE and ECN (explicit congestion notification), but neither of them can be executed.
# Enable Open Ethernet mode switch (config) # oem-mode on # Configure PFC and ECN for RoCEv2 ~~~~ switch (config) # ecn enable force switch (config) # ecn congestion-threshold switch-priority 3 100 force
I would like to know if this is a version issue of MLNX-OS or if the SX1036 cannot utilize ECN in the first place.
The documentation for MLNX-OS does mention RED/ECN support, but only on Spectrum-based switches.
I understand that spectrum-based switches support relative RED/ECN configuration.
And I thought that SwitchX-based switches would support the ECN marking process, even if they don’t support ECN configuration.
If ECN marking is not possible on Switch-X, is there a workaround to perform ECN marking on the SX1036 using feature like Openflow?
Any advice would be greatly appreciated.
