Configuring DHCP Relay Service
This switch supports
DHCP relay service for
attached host devices. If
DHCP relay is enabled,
and this switch sees a
DHCP request broadcast,
it inserts its own IP
address into the request
so that the DHCP server will know the subnet where the client is located.
Then, the switch forwards the packet to the DHCP server. 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.
Command Usage
You must specify the IP address for at least one DHCP server. Otherwise,
the switch’s DHCP relay agent will not forward client requests to a DHCP
server.
