title: snmpwalk on mac OSX not returning all values when grepping
body: <p>I am using snmpwalk on my mac to gather information about a copier. When I run a query for a specific OID, it returns its value correctly:</p>
  
  <pre><code>snmpwalk -v 2c -c public -On 10.x.x.x 1.3.6.1.4.1.253.8.53.13.2.1.8.1.20.101
  
  output: 1.3.6.1.4.1.253.8.53.13.2.1.8.1.20.101 = STRING: "Black Single Impressions"
  </code></pre>
  
  <p>however, when I walk the mib and grep, it does not return this value: </p>
  
  <pre><code>snmpwalk -v 2c -c public -On 10.x.x.x | grep -i 'Black'
  
  output:
  .1.3.6.1.2.1.43.11.1.1.6.1.1 = STRING: "Black Toner, PN unknown;SN4131EE80E00004A8"
   .1.3.6.1.2.1.43.12.1.1.4.1.4 = STRING: "black"
  .1.3.6.1.2.1.43.13.4.1.10.1.1 = STRING: "1-sided paper path, Black/White (45) PPM, Color (45) PPM"
  .1.3.6.1.2.1.43.13.4.1.10.1.2 = STRING: "2-sided long edge feed paper path, Black/White (45) PPM, Color (45) PPM"
  .1.3.6.1.2.1.43.13.4.1.10.1.3 = STRING: "2-sided paper path, Black/White (32) PPM, Color (32) PPM"
  </code></pre>
  
  <p>when I grep for the OID of 'Black Single Impressions' it also returns nothing:</p>
  
  <pre><code>snmpwalk -v 2c -c public -On 10.x.x.x | grep 1.3.6.1.4.1.253.8.53.13.2.1.8.1.20.101
  </code></pre>
  
  <p>why isnt snmpwalk returning everything on a walk? this is kind of important for researching what values equal what, I got lucky finding my example.</p>
