errors about RFC3413 / HLAPI/ ASYNCORE

[nathanbdr]

Good morning all,
first of all, I should point out that I am new to python, it may be that I have basic errors, which is why I am interested in any modification suggestions.

I tried to implement the following code:

coding=utf8

import os
import csv
from pysnmp.entity.rfc3413.oneliner import cmdgen
from pysnmp.proto import rfc1902
from pysnmp.smi import builder, view, compiler

with open('FichiersTest.csv', newline='') as csvfile:
reader = csv.DictReader(csvfile, delimiter=';')
for row in reader:
ip = row['NetworkDeviceIpAddr'].split(" ")[0].split("/")[0]
unite = row['PortName'].split(" ")[1].split("/")[0]
port = row['PortName'].split(" ")[1].split("/")[1]
EquipementType = row['NetworkDeviceType'].split(" ")[0].split("/")[0]
print(row['DeviceDNSName'],' ; ',row['NetworkDeviceIpAddr'],' ; ',row['NetworkDeviceType'],' ; ',row['PortName'],' ; ',row['PortNumber'],' ;')

SNMP_HOST = ip
SNMP_PORT = 161
SNMP_COMMUNITY = 'cumulus'
x=1
y=1
cmdGen = cmdgen.CommandGenerator()

#fonction disable port 4524
def disableport_4524(EquipementType='ERS-4524GT-PWR',SNMP_HOST= ip,x=1,y=1,SNMP_PORT = 161,SNMP_COMMUNITY = 'cumulus'):
x=1
while x<25:
errorIndication, errorStatus, errorIndex, varBinds=cmdGen.getCmd(
#varBinds=cmdGen.getCmd(
cmdgen.CommunityData(SNMP_COMMUNITY),
cmdgen.UdpTransportTarget((SNMP_HOST, SNMP_PORT)),
'1.3.6.1.2.1.2.2.1.7.'+str(x)

                            )
    
    for name,val in varBinds:
            print('%s  = %s' % (name.prettyPrint(), val.prettyPrint()))
    x=x+1

y=1
while y<25:
errorIndication, errorStatus, errorIndex, varBinds=cmdGen.setCmd(
cmdgen.CommunityData(SNMP_COMMUNITY),
cmdgen.UdpTransportTarget((SNMP_HOST, SNMP_PORT)),
('1.3.6.1.2.1.2.2.1.7.'+str(x),rfc1902.Integer('2'))
)
for name,val in varBinds:
print('%s = %s' % (name.prettyPrint(), val.prettyPrint()))
y=y+1

    if EquipementType==('ERS-4524GT-PWR'):
            SNMP_HOST=('NetworkDeviceIpAddr')
            disableport_4524()

def disableport_4850(EquipementType='4950GTS-PWR+',SNMP_HOST= ip,x=1,y=1,SNMP_PORT = 161,SNMP_COMMUNITY = 'cumulus'):
x=1
while x<49:
errorIndication, errorStatus, errorIndex, varBinds=cmdGen.getCmd(
#varBinds=cmdGen.getCmd(
cmdgen.CommunityData(SNMP_COMMUNITY),
cmdgen.UdpTransportTarget((SNMP_HOST, SNMP_PORT)),
'1.3.6.1.2.1.2.2.1.7.'+str(x)

                            )
    print(str(x))
    for name,val in varBinds:
            print('%s  = %s' % (name.prettyPrint(), val.prettyPrint()))
    x=x+1

y=1
while y<49:
errorIndication, errorStatus, errorIndex, varBinds=cmdGen.setCmd(
cmdgen.CommunityData(SNMP_COMMUNITY),
cmdgen.UdpTransportTarget((SNMP_HOST, SNMP_PORT)),
('1.3.6.1.2.1.2.2.1.7.)'+str(y),rfc1902.Integer('2'))
)
print(str(x))
for name,val in varBinds:
print('%s = %s' % (name.prettyPrint(), val.prettyPrint()))
y=y+1

if EquipementType==('4950GTS-PWR+'):
SNMP_HOST=('NetworkDeviceIpAddr')
print("c'est un switch 48 ports!")
disableport_4850()

from a csv file, we interrogate the switches in SNMP. Then we modify the value of the oid to desactivate the ports. For that I have two functions which are similar except that I have the following errors once I run the script.

CTraceback (most recent call last):
File "test copy.py", line 60, in

poll_fun(timeout, map)
File "/usr/lib/python3.6/asyncore.py", line 183, in poll2
r = pollster.poll(timeout)

small precision: my functions work correctly independently without the csv file.

I thank you in advance
