Usage Guidelines

Use this command to configure DHCP smart relay mode to include the secondary IP address as giaddr at the VLAN level.

Example

The following command configures DHCPv4 BOOTP Relay service for the "vlan_100" VLAN, and uses both primary and secondary address(es) of the client VLAN as gateway address. This overrides the VR level configuration.
