ADTRAN AOS Version R10.1.0 Command Reference Manual page 318

Command Reference Guide
debug ip udp
Use the debug ip udp command to activate debug messages associated with User Datagram Protocol
(UDP) send and receive events in AOS. Debug messages are displayed (real time) to the terminal (or
Telnet) screen. Use the no form of this command to disable the debug messages.
These debug events are logged for packets that are sent or received from the router.
Forwarded UDP packets are not included.
The overhead associated with this command takes up a large portion of your router's
resources and at times can halt other router processes. It is best to only use the command
during times when the network resources are in low demand (nonpeak hours, weekends,
etc.).
Turning on a large amount of debug information can adversely affect the performance of
your unit.
Syntax Description
No subcommands.
Default Values
By default, all debug messages in AOS are disabled.
Command History
Release 4.1
Functional Notes
In the debug ip udp information, the message no listener means that there is no service listening on this
UDP port (i.e., the data is discarded).
