no ip helper-address (Global Config)
Use the no form of the command to delete an IP helper entry. The command no ip helper-address with no
arguments clears all global IP helper addresses.
ip helper-address (Interface Config)
Use this command to configure the relay of certain UDP broadcast packets received on a specific interface or
range of interfaces. This command can be invoked multiple times on a routing interface, either to specify
multiple server addresses for a given port number or to specify multiple port numbers handled by a specific
server.

ip | nameserver | netbios-dgm | netbios-ns | ntp | pim-auto-rp | rip | tacacs | tftp
| time]

sent. The server address cannot be in a subnet on the interface where the relay entry is

discard Matching packets should be discarded rather than relayed, even if a global ip helper-
address configuration matches the packet.
dest-udp-port A destination UDP port number from 0 to 65535.
