title: How stable are Cisco IOS OIDs for querying data with SNMP across different model devices?
body: <p>I'm querying a bunch of information from cisco switches using SNMP.  For instance, I'm pulling information on neighbors detected using CDP by doing an snmpwalk on .1.3.6.1.4.1.9.9.23</p>
  
  <p>Can I use this OID across different cisco models?  What pitfalls should I be aware of?  To me, I'm a little uneasy about using numeric OIDs - it seems like I should be using a MIB database or something and using the named OIDs, in order to gain cross-device compatibility, but perhaps I'm just imagining the need for that.</p>
