Hello guys.

We acquired a ConnectX3 to test port virtualization but we fell into the following doubt …

We want to create a trunk on one of the virtualized ports, how to do this in the Mellanox switch, if it sees only the physical port?

Another question, how can we separate each of these virtualized ports into VLANs?

Our idea is to virtualize the port and use one for iSCSI, one for backup and another as trunk, and deliver to the VMs all these virtualized ports on top of a physical port.

Thank you.

Hi Jorge,

Can you please provide more details?

Do you mean to do virtualization on the mellanox switch?
