How to pass variables for a script via SNMP by using snmpget? -

i have 1 simple bash script calls test_snmp, let's say:

#!/bin/bash  echo $1 

i have snmpd.conf set following:

rwcommunity public 127.0.0.1 extend .1.3.6.1.4.1.2021.53 /bin/bash /tmp/test_snmp 

what i'd run snmpwalk command, like:

snmpwalk -v2c -c public 127.0.0.1 .1.3.6.1.4.1.2021.53 "print something" 

from output see oid = iso.3.6.1.4.1.2021.53.3.1.1.9.47.98.105.110.47.98.97.115.104 = "", output of script. i'd pass string "print something", $1 parameter script mentioned above , string (in case "print something") using snmpget command, like:

snmpget -v2c -c public 127.0.0.1 iso.3.6.1.4.1.2021.53.3.1.1.9.47.98.105.110.47.98.97.115.104 

it example, i'm testing options have running scripts via snmp. because if works i'll write scripts run remotely, have run them variables.

does know how it?

thank you
