IP Routing Features UDP Broadcast Forwarding - Continued from the preceding page. - < 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 3-69. < port-name >: Allows use of common names for certain wellknown UDP port numbers.

IP Routing Features
UDP Broadcast Forwarding
— Continued from the preceding page. —
<
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 3-69
.
<
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 routing switch to forward
UDP broadcasts from a client on VLAN 1 for a time protocol server:
ProCurve(config)# ip forward-protocol udp 15.75.11.155
timep
