These commands are exactly right. However, what I had to find out was to use Alt+F1 at the DCUI.

Points of My Scenario
1. I manage 2 clustered ESXi 5.0.0 (VMKernel Release Build 1749766) hosts
2. The vCenter server is a virtual machine in the cluster
3. These hosts were moved to a different building on new infrastructure (different physical switches)
4. I lost network connectivity to the ESXi hosts, and their VMs because the speed and duplex of the management vnics must be changed.
5. I have a working KVM console connection into the ESXI hosts' DCUI (direct console user interface).

QUESTION: How can I change the speed and duplex for adapters, using ONLY the DCUI?

VMware ESXi 5.0.0 - Change Speed/Duplex at DCUI

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
