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 to forward broadcast packets for
specified UDP application ports to remote servers located in another network
segment.
◆ To configure UDP helper, enable it globally (see “Configuring General DNS
Service Parameters” on page 643), specify the UDP destination ports for which
broadcast traffic will be forwarded (see “Specifying UDP Destination Ports” on
page 660), and specify the remote application servers or the subnet where the
servers are located (see “Specifying the Target Server or Subnet” on page 661).
