The default behavior for networking is for DHCP to configure IP. You can override the default behavior after it takes effect. You can also change any settings that are not compatible with your network environment.

Network Configuration Scenarios summarizes the network configuration scenarios that ESXi 4.0 supports.

Network Configuration Scenarios

Scenario

Approach

You want to accept the DHCP-configured IP settings.

Note the IP address that DHCP assigns and use the vSphere Client or another desktop client interface to connect to the ESXi 4.0 host.

One of the following is true:

You do not have a DHCP server.

The ESXi 4.0 host is not connected to a DHCP server.

Your connected DHCP server is not functioning properly.

During the autoconfiguration phase, the software assigns the link local IP address, which is in the subnet 169.254.x.x/16. The assigned IP address appears on the direct console.

You can override the link local IP address by configuring a static IP address using the direct console.

The ESXi 4.0 host is connected to a functioning DHCP server, but you do not want to use the DHCP-configured IP address.

During the autoconfiguration phase, the software assigns a DHCP-configured IP address.

You can make the initial connection by using the DHCP-configured IP address. Then you can configure a static IP address.

If you have physical access to the ESXi 4.0 host, you can override the DHCP-configured IP address by configuring a static IP address using the direct console.

Your security deployment policies do not permit unconfigured hosts to be powered on the network.

Follow the setup procedure in Configure the Network Settings on a Detached Host.
