title: No Such Object available on this agent at this OID
body: <p>i installed a snmpd into a CentOS 7 minimal installation for system parameters search, for instance:</p>
  
  <pre><code>snmpget -v 2c -c public 127.0.0.1 .1.3.6.1.2.1.2.2.1.2
  </code></pre>
  
  <p>for the above command i get the following result:</p>
  
  <pre><code>IF-MIB::ifDescr = No Such Object available on this agent at this OID
  </code></pre>
  
  <p>the iptables in this machine is completely open (Lab VM). Is there any snmpd.conf configuration that must be done to enable the read on specific OID's? The documentation i found about SNMP is really dense and i'm kinda lost haha! Any help is welcome!</p>
  
  <p>Thanks!</p>
