Viewing the UDP Listener Table
The
udpl
command is used to display the UDP Listener Table. This table contains information
about the switch’s UDP end-points on which a local application is currently accepting data-
grams. The UDP Listener Table shows the local IP addresses for each UDP listener and the
local port number for this listener. An IP address of zero (0.0.0.0) indicates that it is listening
on all interfaces.
To view the UDP Listener Table, enter the following command:
udpl
A screen similar to the following appears:

Local Address/Port
The local IP address, and the local port number, for this UDP connection. In the case of a
connection in the listen state, which is willing to accept connections for any IP interface asso-
ciated with the node, the value 0.0.0.0 is used.

For the SNMP Traps (port 162) this is the number transmitted (there is no receive).
For the SNMP Requests (port 161) this is the number of Request PDUs sent and the number of
Response PDUs received.
For RIP (port 520) this is the number of packets received and transmitted.
