title: Zabbix snmpv3 - items doesn't work but snmpwalk does
body: <p>Im using zabbix 4.0.10 on centos 7 machine and i have an issue with cisco switch,
  If i run snmpwalk it works fine from CLI , but as i use a template item it gives errors.
  Sometimes i get user\password incorrect
  And sometimes i get Timeout to the host ( which is not real as snmpwalk and snmpget continue to work from zabbix server CLI)</p>
  
  <p>What am i missing ? i need to set somthing in the snmpd.conf ?
  snmpd.conf:</p>
  
  <pre><code>com2sec notConfigUser  default       zabbix
  group   notConfigGroup v1           notConfigUser
  group   notConfigGroup v2c           notConfigUser
  view    systemview    included   .1.3.6.1.2.1.1
  view    systemview    included   .1.3.6.1.2.1.25.1.1
  access  notConfigGroup ""      any       noauth    exact  systemview none none
  rwcommunity  zabbix
  rwuser zabbix authPriv
  dontLogTCPWrappersConnects yes
  syslocation Unknown (edit /etc/snmp/snmpd.conf)
  syscontact Root &lt;root@localhost&gt; (configure /etc/snmp/snmp.local.conf)
  </code></pre>
  
  <p>snmpwalk:</p>
  
  <pre><code>snmpwalk  -v3 -l authPriv -u zabbix-a SHA -A pass -x AES -X pass 10.0.0.1
  </code></pre>
  
  <p>(my password contained special chars)</p>
  
  <p>And i have the macros i need in zabbix.</p>
