我想关闭并且不关闭交换机的端口

Question

我的交换机是 Catalyst 2960-x 系列，我已经配置了 SNMP，我现在使用 PySNMP，但我是新手，我已经知道我必须使用的命令是这个 "sudo snmpset -v 2c -c SNMPv2-SMI::mib-2.105.1.1.1.3.1.13 i 2" .但是我没有完成它，请有人帮忙。

from pysnmp.hlapi import*
setcommunity = 'EuricoFerreira'
host = '192.168.150.231'
port = 13

snmp_engine = SnmpEngine()

set_gen = setCmd(snmp_engine,
                 CommunityData(setcommunity),
                 UdpTransportTarget((host, 161)),
                 ContextData(),
                 ObjectType(ObjectIdentity('SNMPv2-SMI', 'mib-2', '105.1.1.1.3.1.%d' % port), Integer(2)))

errorIndication, errorStatus, errorIndex, varBinds = next(set_gen)
if errorIndication or errorStatus:
    print('SNMP error: %s' % errorIndication or errorStatus)
else:
    print('SNMP succeeded')

这段代码给我这个错误：

" Traceback (most recent call last):
  File "<string>", line 878, in writeTest
  File "<string>", line 570, in writeTest

During handling of the above exception, another exception occurred:

确保您使用的是最新的 pyasn1/pysnmp。从回溯看来你是运行一些旧的 pyasn1.
