Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 651)

The only unsupported configuration is a Network DHCP server. Client 1 is on a different subnet than
Server 3 and Server 4, which are on the same subnet.
The Brocade DHCP Relay agent forwards DHCP BOOTP broadcast packets from the DHCP clients to
the appropriate server and processes broadcast or unicast packets from the server to forward to the
DHCP client. BOOTP is a network protocol used to obtain an IP address from a DHCP server. Refer to
the following figure.
Supported platforms
The IP DHCP Relay feature is supported on specific Brocade VDX platforms.
The IP DHCP Relay feature is supported on the following Brocade platforms:
• VDX 6710, VDX 6720, and VDX 6730
• VDX 6740, VDX 6740T, and VDX 6740T-1G
• VDX 8770-4 and VDX 8770-8
Configuring IP DHCP Relay
Configure the IP DHCP Relay agent on any Layer 3 (L3) interface using the IP address of the DHCP
server where client requests are to be forwarded. L3 interfaces can be a virtual Ethernet (Ve) or a
physical 1, 10, or 40 Gigabit Ethernet interface.
Configure the IP DHCP Relay agent using the ip dhcp relay address command followed by the IP
address of the DHCP server. Use the use-vrf vrf-name parameter if the DHCP Server and client
interface are on different Virtual Forwarding and Routing (VRF) instances.
The following are considerations and limitations when configuring the IP DHCP Relay agent:
