Usage guidelines
This command enables the DHCP server to ignore the broadcast flag in DHCP requests and broadcast
all responses.
If a DHCP request is from a DHCP client that has an IP address (the ciaddr field is not 0), the DHCP server
always unicasts a response (the destination address is ciaddr) to the DHCP client regardless of whether
this command is executed.
If a DHCP request is from a DHCP relay agent (the giaddr field is not 0), the DHCP server always unicasts
a response (the destination address is giaddr) to the DHCP relay agent regardless of whether this
command is executed.
Examples
# Enable the DHCP server to broadcast all responses.
<Sysname> system-view
[Sysname] dhcp server always-broadcast
