Usage guidelines
DHCP client detects IP address conflict through ARP packets. An attacker can act as the IP address
owner to send an ARP reply. This makes the client unable to use the IP address assigned by the
server. As a best practice, disable duplicate address detection when ARP attacks exist on the
network.
Examples
# Disable the duplicate address.
<Sysname> system-view
[Sysname] undo dhcp client dad enable
dhcp client dscp
Use dhcp client dscp to set the DSCP value for DHCP packets sent by the DHCP client.
Use undo dhcp client dscp to restore the default.
Syntax
dhcp client dscp dscp-value
