我想關機並且不關機交換機的端口

我的交換機是Catalyst 2960-x系列，我已經配置了SNMP，我現在用的是PySNMP，但是我現在已經知道了，我已經知道命令了，我必須使用的是「sudo snmpset -v 2c -c SNMPv2-SMI :: mib-2.105.1.1.1.3.1.13 i 2」。但即使沒有完成，有人可以幫忙。我想關機並且不關機交換機的端口

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')

此代碼是給我這個錯誤：

確保您使用的是最新pyasn1/pysnmp。從回溯看起來你正在運行一些舊的pyasn1。

感謝我做了它我沒有與pyasn1的版本，我也與pysnm 4.3.2的版本，它必須與版本4.3.5。 –

現在我還有一個問題，我怎麼知道我的交換機端口的狀態？所以我可以打開或關閉端口？ –

您應該使用SNMP GET命令來代替SNMP SET命令。按照pysnmp的術語，你應該改變getCmd的'setCmd'並將值部分放入'ObjectType（ObjectIdentity（'SNMPv2-SMI'，'mib-2'，'105.1.1.1.3.1。％d'％port）） '。這樣你將讀取當前的端口狀態，而不是將其設置爲某個狀態。 –
