A list for users of pure-Python SNMP framework <pysnmp-users.lists.sourceforge.net> List-Unsubscribe: <https://lists.sourceforge.net/lists/listinfo/pysnmp-users>, <mailto:pys...@li...?subject=unsubscribe> List-Archive: <http://sourceforge.net/mailarchive/forum.php?forum=pysnmp-users> I was trying to get the example snmptrap.py working using snmpv1. I found one bug and one "usability problem". The bug : in module rfc1157.py in \pysnmp-3.3.5\build\lib\pysnmp\proto\cli\ucd the following line is in error self.apiSetGenericTrap(int(args[2])) it should be self.apiGenSetGenericTrap(int(args[2])) The usability problem is that the module uses port 161 as a default. I believe Traps need to be sent to Port 162. Port 161 is the port for getting and setting SNMP values.

I get incorrect string values, when try to receive MacAddress:
FAQ says, that this problem solved in pysnmp-tools (such as pysnmpget), by using -OT flag.
How can i realize this feature ?
[root:ns:~/ordersw]#>python snmp.py | less
1.3.6.1.2.1.17.4.3.1.1.0.19.169.241.49.224 = '\x00\x13\xa9\xf11\xe0'
1.3.6.1.2.1.17.4.3.1.1.168.249.75.1.67.50 = '\xa8\xf9K\x01C2'
1.3.6.1.2.1.17.4.3.1.1.168.249.75.1.67.19 = '\xa8\xf9K\x01C\x13'
and second question:
when i try execute with string OID, not turple, a got an error like this:
[root:ns:~/ordersw]#>python snmp.py
Traceback (most recent call last):
File "snmp.py", line 29, in <module>
dot1dTpFdbTable
<skipped>
TypeError: can only concatenate tuple (not "str") to tuple
But, documentation says:
class ObjectIdentifier( objectIdentifier )
Create an ASN.1 Object Identifier object. The objectIdentifier parameter represents Object Identifier value. It should be either a tuple or tuple-like object or a string representing Object Identifier in dotted notation (like "1.3.6.1").
Instances of this class mimic basic properties of Python tuple. Sub-OIDs of an OID translate into tuple components.
For more information on ObjectIdentifier class properties, refer to PyASN1 documentation.
my source code:
from pysnmp.entity.rfc3413.oneliner import cmdgen
from pysnmp.proto import rfc1155, rfc1902, api
from pyasn1.codec.ber import encoder, decoder
hostname = '192.168.202.196'
dot1dTpFdbTable = (1,3,6,1,2,1,17,4,3)
cmdGen = cmdgen.CommandGenerator()
cmdGen.ignoreNonIncreasingOid = True
errorIndication, errorStatus, errorIndex, \
varBindTable = cmdGen.nextCmd(
cmdgen.CommunityData('tlk-read', 'tlk-read'),
cmdgen.UdpTransportTarget((hostname, 161)),
dot1dTpFdbTable
)
if errorIndication:
print errorIndication
else:

Personally I have a function I use to do this. just hand it the object, and it returns the macs string in lowercase hex.
import binascii
def convertMac(octect):
'''
This Function converts a binary mac address to a hexadecimal string representation
'''
temp = list(octect)
mac = []
for x in temp:
mac.append(binascii.b2a_hex(x))
return ":".join(mac)

i cut my code, so now it's follow:

errorIndication, errorStatus, errorIndex, \
varBindTable = cmdGen.nextCmd(
cmdgen.CommunityData('tlk-read', 'tlk-read'),
cmdgen.UdpTransportTarget((hostname, 161)),
dot1dTpFdbTableStr

Line 19 is "errorIndication, errorStatus, errorIndex, \
varBindTable = cmdGen.nextCmd(

there is an error:

I've found working solution for me,thanks! But if it would helpful, i can help in debugging - what's wrong
If my solution is correct - examples should be update
dot1dTpFdbTableStr = "1.3.6.1.2.1.17.4.3"

varBindTable = cmdGen.nextCmd(
cmdgen.CommunityData(community, community),

Hi all,
I would appreciate some help with the getcmd in the following code. I get a
serialization error.
Eventually i will have multiple targets and would like to keep that in a
loop. The OID will also be a custom OID without loading the MIB.
Thank you

Hi Johan,
You are supposed to pass a sequence of OIDs, not just one:
