Adding Secondary Management NIC to ESXi Host

Hi,

We currently have request from a customer to add a secondary management NIC to two ESXi servers so both ourselves and the customer can connect to the hosts if vCenter becomes unavailable.

Can someone confirm if this is feasible or will the hosts get confused and become unreachable? Sorry if this is an obvious answer it’s just I've only ever seen configuration with one management NIC.

Thanks in advance.
