Event Management Best Practices › SNMP Traps

SNMP Traps

CA 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.

If you are not currently using this port, to edit your PROFILE’s PORT

1. Locate the following line:

   161 UDP SNMPQE
   

2. Change this line to:

   ; 161 UDP SNMPQE
   

If port 161 is unavailable, you must select the port you want and update file /cai/nsmem/snmp/scripts/envset as follows:

1. Locate the following lines:

   # port number to listen on
   

   CAICATD0001=161
   

   export CAICATD0001
   

2. Change these lines as follows:

   # port number to listen on
   

   CAICATD0001=9161
   

   export CAICATD0001
   

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