Enable catrapd to Receive SNMP Traps

Unicenter NSM has the ability to send and receive SNMP traps. Any received traps will appear on the Event Management console.

To receive traps, the daemon catrapd must be running. By default, the process listens on port 161. Your TCP/IP procedure has a PROFILE DD that contains reserved port numbers.

Enable catrapd if you want to route SNMP messages from other consoles by making port 161 available if possible.

To enable catrapd using the default port

Modify the TCPIP profile (the data set used in DD statement PROFILE in your TCPIP proc) to ensure that:

• Port 161 is not reserved for OSNMPD (the SNMP Agent)
• AUTOLOG does not start OSNMPD

To enable catrapd using a different port

Add the following two lines to the envset script in the $CAIGLBL0000/snmp/scripts directory if port 161 cannot be used:

CAICATD0001=nnn

export CAICATD0001

Note: CAICATD0001=nnn is the port number to listen on, replace nnn with the actual port number.

You can use the catrap program to send a trap. The syntax for the command is described in the Reference Guide.
