Configuring an IP helper address

To add the IP address of a DHCP server for a specified VLAN on a routing switch, enter the ip helper-address command at the VLAN configuration level as in the following example:

HP Switch(config)# vlan 1
HP Switch(vlan-1)# ip helper-address ip-addr 

To remove the DHCP server helper address, enter the no form of the command:

HP Switch(vlan-1)# no ip helper-address ip-addr

Operating notes

  • You can configure up to 4000 IP helper addresses on a routing switch. The helper addresses are shared between the DHCP relay agent and UDP forwarder feature.

  • A maximum of sixteen IP helper addresses is supported in each VLAN.
