FORWARDING UDP SERVICE REQUESTS
This section describes how this switch can forward UDP broadcast packets
originating from host applications to another part of the network when an
local application server is not available.
COMMAND USAGE
◆ Network hosts occasionally use UDP broadcasts to determine
information such as address configuration, and domain name mapping.
These broadcasts are confined to the local subnet, either as an all hosts
broadcast (all ones broadcast - 255.255.255.255), or a directed subnet
broadcast (such as 10.10.10.255). To reduce the number of application
servers deployed in a multi-segment network, UDP helper can be used
