We are in the process of connecting two different switches (One is Arista Switch and the other one is a Cisco Nexus 5672UP) on two different networks between two different labs on a single floor using Mellanox cable (P/N# MC220731V-030). As we connected one end of the Mellanox cable to the QSFP+ port on the Cisco Nexus 5672UP, and we did not see any visual signs that the cable is connected to switch. When we looked it on the switch from CLI, it shows the following:

So the question is, how to configure this Mellanox cable with the Cisco Nexus 5672UP on the QSFP+ port to connect between two different switches (Cisco Nexus 5672UP and Arita) on two different network?
Thanks
