< ip-address >: This can be either of the following:
• The unicast address of a destination server on another
subnet. For example: 15.75.10.43.
• The broadcast address of the subnet on which a
destination server operates. For example, the following
address directs broadcasts to All hosts in the 15.75.11.0
subnet: 15.75.11.255: .
Note: The subnet mask for a forwarded UDP packet is the same
as the subnet mask for the VLAN (or subnet on a multinetted
VLAN) on which the UDP broadcast packet was received from
a client.
< udp-port-# >: Any UDP port number corresponding to a UDP
application supported on a device at the specified unicast
address or in the subnet at the specified broadcast address. For
more information on UDP port numbers, refer to "TCP/UDP
Port Number Ranges" on page 11-81.
< port-name >: Allows use of common names for certain well-
known UDP port numbers. You can type in the specific name
instead of having to recall the corresponding number:
dns: Domain Name Service (53)
ntp: Network Time Protocol (123)
netbios-ns: NetBIOS Name Service (137)
netbios-dgm: NetBIOS Datagram Service (138)
radius: Remote Authentication Dial-In User Service (1812)
radius-old: Remote Authentication Dial-In User Service (1645)
rip: Routing Information Protocol (520)
snmp: Simple Network Management Protocol (161)
snmp-trap: Simple Network Management Protocol (162)
tftp: Trivial File Transfer Protocol (69)
timep: Time Protocol (37)
For example, the following command configures the router to forward UDP
broadcasts from a client on VLAN 1 for a time protocol server:
HPswitch(config)# ip forward-protocol udp 15.75.11.155
timep
