Command Mode INTERFACE
Usage
Information
The DHCP server is supported only on L3 interfaces. After you configure an IP helper address, the
address forwards UDP broadcasts to the DHCP server. You can configure multiple helper addresses on
an interface by repeating the same command for each DHCP server address. The no version of this
command returns the value to the default. The client-facing and server-facing interfaces must be in the
same VRF.
Example (IPv4)
OS10(config)# interface eth 1/1/22
OS10(conf-if-eth1/1/22)# ip helper-address 20.1.1.1 vrf blue
Supported
