dhcp udp-checksum enable

Function

The dhcp udp-checksum enable command enables a device to add the UDP header checksum to DHCP packets to be sent.

The undo dhcp udp-checksum enable command disables a device from adding the UDP header checksum to DHCP packets to be sent.

By default, the UDP header checksum carried in DHCP packets sent by a device is 0, and the peer device does not verify the checksum.

Usage Guidelines

Usage Scenario

If the peer device does not comply with protocol standards, the peer device still verifies the UDP header checksum when the checksum carried in DHCP packets is 0. In this case, you can run the dhcp udp-checksum enable command to enable the device to add the UDP header checksum to DHCP packets to be sent.

Precautions

A device can add the UDP header checksum to DHCP packets to be sent only if the device functions as a DHCP server.
