Как получить значение mac и vlan из таблицы fdb использует python?
В bash snmpwalk работает нормально:
snmpwalk -v2c -c pub 192.168.0.100 1.3.6.1.2.1.17.7.1.2.2.1.2
pysnmp:
import os, sys
import socket
import random
from struct import pack, unpack
from datetime import datetime as dt
from pysnmp.entity.rfc3413.oneliner import cmdgen
from pysnmp.proto.rfc1902 import Integer, IpAddress, OctetString
ip='192.168.0.100'
community='pub'
value=(1,3,6,1,2,1,17,7,1,2,2,1,2)
generator = cmdgen.CommandGenerator()
comm_data = cmdgen.CommunityData('server', community, 1) # 1 means version SNMP v2c
transport = cmdgen.UdpTransportTarget((ip, 161))
real_fun = getattr(generator, 'getCmd')
res = (errorIndication, errorStatus, errorIndex, varBinds)\
= real_fun(comm_data, transport, value)
if not errorIndication is None or errorStatus is True:
print "Error: %s %s %s %s" % res
else:
print "%s" % varBinds
output: [(ObjectName (1.3.6.1.2.1.17.7.1.2.2.1.2), NoSuchInstance (''))]
import netsnmp
def getmac():
oid = netsnmp.VarList(netsnmp.Varbind('.1.3.6.1.2.1.17.7.1.2.2.1.2'))
res = netsnmp.snmpgetbulk(oid, Version = 2, DestHost='192.168.0.100',
Community='pub')
return res
print getmac()
вывод: ('27', '27', '25', '27', '27', '27', '24', '27', '25', '18', '4', ' 27, 25, 27, 27, 25, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 23, "25" , "27" , "27" , "27" , "25" , "27" , "25" , "27" , "27" , "25" , "27" , 27, 27, 27, 27, 27, 27, 27, 27, 25, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 25, "25" , "25" , "7", "27" , "27" , "9", "25" , "27" , "20", "19", "27" , "27" , 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 11, 25, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27, 25, 27, 27, 27, 27, 27, 27, 27, 27, 27, 2, 27, 5, '27', '27', '27')
Firs script (pysnmp) возвращает NoSuchInstance. Второй script (netsnmp) возвращает список портов, но без mac и vlan. Что не так?
