Example walk script fails with dotted OID #360

Open yellowpattern opened 4 years ago

yellowpattern commented 4 years ago

I haven't installed the SMI module, so I used a dotted OID in place of the name:

for (errorIndication,
     errorStatus,
     errorIndex,
     varBinds) in nextCmd(SnmpEngine(),
                          UsmUserData('usr-md5-none', 'authkey1'),
                          UdpTransportTarget(('1.1.1.1', 161)),
                          ContextData(),
                          ObjectType(ObjectIdentity('1.3.6.1.'))):

and I get:

I don't think using pysnmp without pysmi is a supported scenario.
