ip dhcp restart relay
Default Setting

Command Mode
Privileged Exec
Command Usage
This command is used to configure DHCP relay functions for host devices attached
to the switch. If DHCP relay service is enabled, and this switch sees a DHCP request
broadcast, it inserts its own IP address into the request so the DHCP server will
know the subnet where the client is located. Then, the switch forwards the packet
to the DHCP server on another network. When the server receives the DHCP
request, it allocates a free IP address for the DHCP client from its defined scope for
the DHCP client's subnet, and sends a DHCP response back to the DHCP relay agent
(i.e., this switch). This switch then broadcasts the DHCP response received from the
server to the client.
Example
In the following example, the device is reassigned the same address.
