Usage Guidelines

Usage Scenario

Network scale and complexity increase makes network configurations complex. For example, computers frequently change their locations, and IP addresses are insufficient for these computers. The DHCP protocol is developed to address these problems. The dhcp enable command enables the DHCP function on the device.

Precautions

The dhcp enable command is the prerequisite for configuring DHCP-related functions, including DHCP relay, DHCP snooping, and DHCP server. These functions take effect only after the dhcp enable command is run. After the undo dhcp enable command is run, all DHCP-related configurations of the device are deleted. After DHCP is enabled again using the dhcp enable command, all DHCP-related configurations of the device are restored to the default configurations.

Example
