Configuring the UDP Broadcast Redirector
To locate a server that can provide a particular network service, many IP hosts rely on the use of
LAN broadcasts to send UDP service requests. The UDP port number contained in the broadcast
request packet identifies the service being requested.
Table 23 shows the port numbers and their
corresponding requested services.
The UDP Broadcast Redirector enables you to configure any Routing Services enabled device to
forward the UDP packets that it receives as LAN broadcasts, directly to the appropriate server.
UDP service requests that are sent as LAN broadcasts by clients of applications such as Host
Name, Domain Name, and Bootstrap servers, can be redirected to any server on any network
segment.
To configure the UDP Broadcast Redirector, complete the following steps:
1. Use the arrow keys to highlight the UDP Port option under System Level Setup.
2. ENTER the UDP port number of the UDP service request packets that you want to redirect
(refer to
Table 23 ) and then press ENTER.
