I knew I miss something :(
Usually daemons have switch something like 'keep in foreground'
So script can be changed to
while :; do
snmp_agen --keep-in-foreground
done
And whole script should be run in the background.
If you want some way to shut down the agent you can kill script and then agent.
Or catch say SIGTERM in the script and kill agent from the script itself.
