What is the recommended method for IP address allocation for the management interface of VMware ESXi hosts in a VMware Cloud Foundation (VCF) environment?
A.
Dynamic IP addresses assigned via DHCP without any reservations
B.
Dynamic IP addresses assigned via DHCP with a reservation based on MAC address
C.
Static IP addresses assigned manually
D.
Static IP address assigned using VMware NSX IP Pools
As per the VMware Cloud Foundation 5.2 official documentation (Design and Configuration Guides), it is a best practice and requirement to configure ESXi management interfaces in the management domain withstatic IP addresses and host names. Automated or dynamic methods—such as DHCP, even with reservations—arenot supportedfor this purpose. Instead, each ESXi host’s management network (i.e., the VMkernel management interface) must bemanually assigneda unique and consistent static IP.
Here is theexact extractfrom the official VMware technical documentation:
“Allocate statically assigned IP addresses and host names across all ESXi hosts in the default management cluster. Ensures stability across the VMware Cloud Foundation instance, makes it simpler to maintain and track, and to implement a DNS configuration.”
