debug ip udp

Use the debug ip udp command to activate debug messages associated with User Da tagram Protocol
(UDP) send and receive events in the 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.
Syntax Description
No subcommands.
Default Values
By default, all debug messages in the AOS are disabled.
Applicable Platforms
This command applies to the NetVanta 300, 1000, 1000R, 2000, 3000, 4000, and 5000 and
Total Access 900 Series units.
Command History
Release 4.1 Command was introduced.
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).
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 (non-peak hours, weekends,
etc.).
