Hi Hany,
Ideally you should see traps getting generated when you stop and start SBR process(using SBRD script).
Trap messages that SBR sends are very well documented in our reference guide, refer chapter 21 from below:
Also please check if port 162 is used by any other process. If so, you could alter the port number in jnprsnmpd.conf and try again.
