title: Does net-snmp support AES-192 and AES-256 encryption?
body: <p>The network device has been configured with snmpv3 users which uses AES192 as the privacy protocol.But when the following command is executed</p>
  
  <pre><code>snmpwalk -v3 -l authPriv -u user -a SHA -A authpass -x AES256 -X privpass device_ip:161 oid
  </code></pre>
  
  <p>It throws the following error</p>
  
  <pre><code>Invalid privacy protocol specified after -x flag: AES256
  </code></pre>
  
  <p>but when i tried using AES128 encryption the snmpwalk worked perfectly fine,which made me think if AES192&amp;256 features are supported if not why was it not included.</p>
