Command Mode Interface (VLAN) Configuration mode User Guidelines Enable DHCP Relay using the ip helper enable command. The interface configuration always takes precedence over global configuration. However, if there is no interface configuration, then global configuration is followed. Example The following example enables the circuit ID and remote agent ID options on vlan 10. console(config)#interface vlan 10 console(config-if-vlan10)#ip dhcp relay information option-insert ip helper-address (global configuration) Use the ip helper-address (global configuration) command to configure the relay of certain UDP broadcast packets received on any interface. To delete an IP helper entry, use the no form of this command. Syntax ip helper-address server-address [ dest-udp-port | dhcp | domain | isakmp | mobile-ip | nameserver | netbios-dgm | netbios-ns | ntp | pim-auto-rp | rip | tacacs | tftp | time ] no ip helper-address [server-address] [ dest-udp-port | dhcp | domain | isakmp | mobile-ip | nameserver | netbios-dgm | netbios-ns | ntp | pimauto-rp | rip | tacacs | tftp | time ] • server-address - The IPv4 unicast or directed broadcast address to which relayed UDP broadcast packets are sent. The server address cannot be an IP address configured on any interface of the local router. • dest-udp-port - A destination UDP port number from 0 to 65535. • port-name - The destination UDP port may be optionally specified by its name. Whether a port is specified by its number or its name has no effect on behavior. The names recognized are as follows: dhcp (port 67), domain IP Helper/DHCP Relay Commands 905
