a). Highlight the appropriate VLAN ID and press Enter. A screen similar to the
following appears.
b). To add a relay IP, hold down the Shift key and press +. A setup screen
will appear. Highlight the appropriate interface and press Enter.
c). You can enable/disable DHCP Gateway, set Maximum Hops number, set
the Delay time (in seconds) and specify up to three more preferred
servers in the screen. Please move the highlight and press Enter to setup
these items.
This DHCP relay function allows the DHCP request being routed to the DHCP
server which is in different IP subnet on another VLAN.
Notes: About DHCP Protocol
Dynamic Host Configuration Protocol (DHCP), described in RFC 1541, is an
extension of the Bootstrap Protocol (BOOTP). DHCP allows hosts on a TCP/IP
network to dynamically obtain basic configuration information. When a DHCP
client starts, it broadcasts a DHCP Request packet, looking for DHCP
servers. DHCP servers respond to this packet with a DHCP Response
packet. The client then chooses a server to obtain TCP/IP configuration
information, such as its own IP address. Since DHCP uses broadcast
mechanism, a DHCP server and its client must physically reside on the same
subnet. However, it's not practical to have one DHCP server on every
subnet; in fact in many cases, DHCP/BOOTP clients and their associated
DHCP/BOOTP server(s) do not reside on the same IP network or subnet. In
such cases, a third-party agent is required to transfer BOOTP messages
between clients and servers. BOOTP/DHCP Relay, described in RFC 1542,
enables a host to use a BOOTP or DHCP server to obtain basic TCP/IP
configuration information, even if the servers do not reside on the local
subnet. When a Intelligent Switch with BOOTP/DHCP Relay Agent receives a
DHCP Request packet destined for a BOOTP/DHCP server, it inserts its own
IP address into the DHCP Request packet so the server knows the subnet
