Configures the DHCP server address.

Syntax
ip helper-address address [vrf vrf-name]
Parameters
  • address — Enter the IPv4 address to forward UDP broadcasts to the DHCP server in A.B.C.D format.
  • vrf vrf-name — (Optional) Enter vrf and then the name of the VRF through which the host address is reached.

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 Releases
