尝试使用pysnmp为snmpv3运行getp时,出现错误

pysnmp.smi.error.WrongValueError:WrongValueError({'msg':WrongValueError(),'name':(1、3、6、1、6、3、15、1、2、2、1、5 ,24,48,48,48,48,49,100,51,98,48,48,48,48,55,53,100,49,97,99,49,48,48,49,48,49 ,5,107,107,48,51,48),'idx':3})

from pysnmp.hlapi import *

errorIndication, errorStatus, errorIndex, varBinds = next(
getCmd(SnmpEngine(),
       UsmUserData('USERNAME',authKey='AUTHKEY', privKey='PRIVKEY', authProtocol='usmHMACSHAAuthProtocol', privProtocol='usmAESCfb256Protocol',
                           securityEngineId=OctetString(hexValue='0000303010')),
       UdpTransportTarget(('<IP-ADDR>', <PORT>)),
       ContextData(),
       ObjectType(ObjectIdentity('<MIB-FILE-NAME>','<MIB-NAME>',<INDEX>)))

相同的代码适用于带有社区字符串而不是UsmUserData的SNMP-V2。但是,不适用于SNMP-V3。

回溯时间太长,没有任何线索

确保您的身份验证和私钥符合基础加密算法所需的最小长度。对于任何算法,键的长度至少应为8个以上字符。

请检查并确保authProtocol和privProtocol不作为字符串而是作为数字集提及,例如:代替使用'des'作为authprotocol使用(1、3、6、1、6、3、10、1, 2,2)。
