Syntax
ip helper-address { server-address | discard } [ 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 [
domain | isakmp | mobile-ip | nameserver | netbios-dgm | netbios-ns | ntp
| pim-auto-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.
• 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.
•
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
(port 53), isakmp (port 500), mobile-ip (port 434), nameserver (port 42),
netbios-dgm (port 138), netbios-ns (port 137), ntp (port 123), pim-auto-
rp (port 496), rip (port 520), tacacs (port 49), tftp (port 69), and time
(port 37). Other ports must be specified by number.
