As far as I know all those mellanox cards are 56gig infiband and 40gig eth. I don't think you can get 56Gig eth out of one.
56gbe is a proprietary implementation of ethernet.
You need every component to support it:
You need every component to support it:
- the switch(es)
- the nics
- the cables or transceivers (they must implement the qsfp14 specification aka sff-8685)
MCX354A indeed support 56gbe , only need is 56gbe cable

No need install 56gbe license which now in 3.6.1002 default, only need 56gbe dac and change port speed

So I got 56gb working with a ConnectX-3 using a DAC to the server. Anyone know what optics I can use to run to a different room though? Need a 75ft run.
I have
EMC 019-078-048 4x14G FDR FTL414QB2N-E5
and
Brocade 57-1000267-01 4x16G Xbr-000232
and they don't work.

It has been a while since I did my conversion. I am now in need of running eth mode but find my switch does not have VPI mode as several others posted here. For those of you have VPI enabled, how did you do it? I went back to the guide but could not find anything related. TIA!
Can you point me where on GUI to change it? I could not find it and the ETH mgmt button on the top menu is grayed out.
Forgive me...first time working with eth mode: I cannot establish eth connection using the switch. The ports on the switch are set to eth mode; the host adapters (FreeNAS and a Windows server) are set to eth mode; Direct connection between the two hosts succeeded with the same cable. What am I missing?
attached is a screenshot of the port.

according your picture ， you still in vpi mode， you need read the manual change part 3 into eth mode use clip command, or change cable
Sorry, I don't get it? I did change the port type of port 3 to ethernet mode, which the screenshot showed? And here is what I had for port type
Code:
Port Protocol Config
Port(s)
Type
Apply
Port Type Info
Protocol Ports
InfiniBand 1/1, 1/2, 1/4, 1/5, 1/6, 1/7, 1/8, 1/9, 1/11, 1/12
Ethernet 1/3, 1/10As for the cable, I used exactly the same one as the one I used to connect the two hosts successfully?
Thanks for the suggestion on the manual. I was doing that to try to troubleshoot. But I found not much I can do since the CLI is not working as the manual described. For example, the manual says you run "configure terminal" to get to the config mode, which I am getting a command not found error...
