[pysnmp-users] extracting values from responses

[Andrew G. <ak...@gm...>]

Greetings:

Using pysnmp 4.3.9 on python 2.7.  I'm following the SNMPv3 example at

> http://pysnmp.sourceforge.net/examples/current/v3arch/manager/cmdgen/get-v3.html


How do I assign the returned value to a variable?
When I issue a command like:
rtnval = snmpEngine.transportDispatcher.runDispatcher()
1.3.6.1.4.1.10002.2.30.1.1.1.3.16793610.1.1 = -100

But, rtnval  is empty:
 >>> type(rtnval)
<type 'NoneType'>

Is there anyway to extract the value (in this case -100)?

Thank you.
