Enabling and Disabling DHCP

You can enable or disable the DHCP feature on the device. By default, DHCP is disabled.

When the DHCP feature is disabled, you cannot configure the DHCP relay agent, DHCP snooping, or any of the features that depend on DHCP. In addition, all DHCP configuration is removed from the device.

For more information, see the Cisco Nexus 9000 Series NX-OS Security Configuration Guide, Release 7.x.
