Usage guidelines

This feature enables the DHCP server to compare the chaddr field of a received DHCP request with the source MAC address in the frame header. If they are the same, the DHCP server verifies the packet as legal and continues processing the packet. If they are not the same, the DHCP server discards the request.

Examples

# Enable MAC address check on the DHCP server.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] dhcp server check mac-address
