Configure DHCP Relay
Before you begin
If the agent IP address is a VLAN or port IP address, you must enable DHCP Relay on that VLAN or port within the VLAN context. However, if the agent IP address is a VRRP address, you do not need to enable DHCP Relay on the VLAN or port in which the VRRP address resides.
About this task
After you configure the BOOTP/DHCP relay on an IP interface, you can configure forwarding paths to indicate where packets are forwarded. The forwarding paths are based on the type of packet and where the packet is received.

AgentAddr |

You cannot specify a Secondary IP Interface address as the agent IP address in the forwarding path. To make DHCP aware of Secondary IP Interfaces, you must enable DHCP Smart Relay. |
ServerAddr |
This parameter is either the IP address of the BOOTP/DHCP server or the address of another local interface.

Enable |
Enables BOOTP/DHCP relay. |
Mode |
Specifies the type of messages relayed:
The default is to forward both BOOTP and DHCP messages. |
