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).

Usage Examples

The following is sample output for this command:

>enable

#debug ip udp

2003.02.17 07:38:48 IP.UDP RX: src=10.200.3.236:138, dst=10.200.255.255:138, 229 bytes, no listener

2003.02.17 07:38:48 IP.UDP RX: src=10.200.2.7:138, dst=10.200.255.255:138, 227 bytes, no listener

2003.02.17 07:38:48 IP.UDP RX: src=10.200.201.240:138, dst=10.200.255.255:138, 215 bytes, no

listener

Note

These debug events are logged for packets that are sent or received from the router.

Forwarded UDP packets are not included.

Caution

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.).
