Procedure
1 Run vicfg-dns without command-specic options to display DNS properties for the specied server.
vicfg-dns <conn_options>
The information includes the host name, domain name, DHCP seing (true or false), and DNS servers
on the ESXi host.
2 If the DNS properties are set, and you want to change the DHCP seings, you must specify the virtual
network adapter to use when overriding the system DNS.
v_nic must be one of the VMkernel network adapters.
You can override the existing DHCP seing by using the following command.
vicfg-dns <conn_options> --dhcp yes --v_nic <vnic>
Manage an NTP Server
Some protocols, such as Kerberos, must have accurate information about the current time. In those cases,
you can add an NTP (Network Time Protocol) server to your ESXi host.
I No ESXCLI command exists for adding and starting an NTP server.
The following example illustrates seing up an NTP server. Specify one of the options listed in “Connection
Options for vCLI Host Management Commands,” on page 19 in place of <conn_options>.
Procedure
1 Run vicfg-ntp --add to add an NTP server to the host specied in <conn_options> and use a host name
or IP address to specify an already running NTP server.
vicfg-ntp <conn_options> -a 192.XXX.XXX.XX
2 Run vicfg-ntp --start to start the service.
vicfg-ntp <conn_options> --start
3 Run vicfg-ntp --list to list the service.
vicfg-ntp <conn_options> --list
4 Run vicfg-ntp --stop to stop the service.
vicfg-ntp <conn_options> --stop
5 Run vicfg-ntp --delete to remove the specied NTP server from the host specied in <conn_options>.
vicfg-ntp <conn_options> --delete 192.XXX.XXX.XX
Manage the IP Gateway
If you move your ESXi host to a new physical location, you might have to change the default IP gateway.
You can use the vicfg-route command to manage the default gateway for the VMkernel IP stack. vicfg-
route supports a subset of the Linux route command’s options.
I No ESXCLI command exists to manage the default gateway.
If you run vicfg-route with no options, the command displays the default gateway. Use --family to print
the default IPv4 or the default IPv6 gateway. By default, the command displays the default IPv4 gateway.
Specify one of the options listed in “Connection Options for vCLI Host Management Commands,” on
page 19 in place of <conn_options>.
