I’m troubleshooting a ConnectX-4 Lx stuck at 1Gbps on a machine that was previously running fine at 40Gbps with ConnectX-3.
I can’t seem to manually set the link speed:
>Mlx5Cmd.exe -LinkSpeed -Name "Ethernet 2" -Query
Link is down
Couldn't query the linkspeeds supported by cable since the link is down
LinkSpeeds supported by device only:
1 Gbps
10 Gbps
25 Gbps
40 Gbps
>Mlx5Cmd.exe -LinkSpeed -Name "Ethernet 2" -Set 1
ERROR: set command is not supported.
>Mlx5Cmd.exe -LinkSpeed -Name "Ethernet 2" -Set 10
ERROR: set command is not supported.
>Mlx5Cmd.exe -LinkSpeed -Name "Ethernet 2" -Set 25
ERROR: set command is not supported.
>Mlx5Cmd.exe -LinkSpeed -Name "Ethernet 2" -Set 40
ERROR: set command is not supported.
How do I get this to work? Thanks!
