Arista 7050TX-72Q 40 Gbps Port

I trying to connect my Mellonox Connect-x Pro to a Arista [Arista 7050TX-72Q 40 Gbps port. I see card is good and connect at 10gbps. I appears the switch is breaking the port into 4x 10gbps connections. How do I change that to a single 40gbps connection.

Hmm, I haven’t worked on a Arista stuff before, but looking at the documentation these commands might help:

Check for port-groups via

show hardware port-group

This should list something like this, the key here is to get what ID number is being used

Portgroup: 1    Active Ports: Et17-20
Port            State
------------------------------------------
Ethernet17      Active
Ethernet18      Active
Ethernet19      Active
Ethernet20      Active
Ethernet15/1    ErrDisabled
Ethernet15/2    ErrDisabled
Ethernet15/3    ErrDisabled
Ethernet15/4    ErrDisabled

Once you get the port-group ID, using this command (in configure mode) should restore it back to a 40G port:

default hardware port-group 1 (or whatever the number is)

You should also be able to find the port-group command in the running-config

show running-config

Hope this helps.
