Configuring the UDP template
A feature that uses the UDP template performs the UDP operation to test the following items:
•
Reachability of a specific port on the NQA server.
•
Availability of the requested service on the NQA server.
In UDP template view, you can specify the expected data to be returned. If you do not specify the
expected data, the UDP operation tests only whether the client can receive the response packet from
the server.
The UDP operation requires both the NQA server and the NQA client. Before you perform a UDP
operation, configure a UDP listening service on the NQA server. For more information about
configuring the UDP listening service, see "
