DHCP Relay configuration with NETCONF overview
This chapter provides procedures for configuring DHCP Relay using NETCONF RPCs. Refer to the
Network OS Administrator’s Guide for the following related information:
• An overview of DHCP Relay, including descriptions of how active DHCP Relay functions
• How to monitor DHCP Relay
Using the NETCONF interface, you can perform the following DHCP Relay-related operations:
• Use the <edit-config> remote procedure call (RPC) to configure DHCP Relay.
• Use the <get-config> RPC to verify all or part of the DHCP Relay configuration.
DHCP Relay parameters are defined in the brocade-dhcp YANG module. For a structural map of the
YANG module, refer to the Network OS YANG Reference Manual.
Configuring DHCP Relay
The following are considerations and limitations when configuring the IP DHCP Relay agent:
• You can configure the feature in standalone mode (applicable switches only) or VCS mode.
• You can configure up to four DHCP server IP addresses per interface. When multiple addresses
are configured, the relay agent relays the packets to all server addresses.
• The DHCP server and clients it communicates with can be attached to different Virtual
Forwarding and Routing (VRF) instances. When clients and the DHCP server are on different
VRF instances, use the <server-vrf-name> node with the <relay-ip-addr> node, where
<server-vrf-name> is the VRF where the DHCP server is located. For more information on VRF
support for the IP DHCP Relay, refer to
Chapter 36, “Configuring VRF” .
The following is an example of configuring an IP DHCP Relay address on a 10-gigabit Ethernet
interface. The 10-gigabit Ethernet interface is modified with the DHCP Relay container's
<relay-ip-addr> node to set the IP address.
