[Pysnmp-dev] noSuchInstance

[Guy M. <gu...@p-...>]

Hi,

I am trying to use the pysnmp with the basic operation of GETREQUEST from a
network device that support SNMP and I responded with "noSuchInstance"
although this specific OID has value and it can be seen by "AdnentNet" Snmp
browser, the code I am using is:

from pysnmp import role, v2c, asn1

######################################################################
req = v2c.GETREQUEST()
tr = role.manager(('10.1.12.85', 161))
(rawrsp, src) = tr.send_and_receive( \
        req.encode(community='guy', \
                   encoded_oids=map(asn1.OBJECTID().encode,[
'1.3.6.1.4.1.5655.4.1.6.3'])))
rsp = v2c.RESPONSE()
rsp.decode(rawrsp)
oids = map(lambda x:x[0], map(asn1.OBJECTID().decode, rsp['encoded_oids']))
print oids
vals = map(lambda x: x[0](), map(asn1.decode, rsp['encoded_vals']))
print map(asn1.decode, rsp['encoded_vals'])
print vals

######################################################################

and the output I recieve is:

###########################################

['.1.3.6.1.4.1.5655.4.1.6.3']
[(noSuchInstance(''), '')]
['']

###########################################

Appreciate your help

Guy.
