Practical SNMP White Paper

If your network is spread out across a wide area with many unmanned sites, you need SNMP monitoring. There's just no way that you and your team can watch all of your gear without some form of automated monitoring. The network is simply too big, and there are too few hours in a day to be constantly driving between network sites, burning both fuel and labor time.

SNMP monitoring is distinct from other forms of monitoring because it involves the use of SNMP protocol. SNMP, of course, stands for "Simple Network Management Protocol").

SNMP messages are, most commonly, created by an SNMP agent (some kind of SNMP-enabled gear at the site) and received by a central SNMP manager (a software program, ideally running on its own dedicated hardware platform). Sometimes, an SNMP manager will send a message to an SNMP agent. This message might ask, "What is the current temperature inside your site enclosure?", or any number of other important questions.

You don't need to be an SNMP expert to monitor your network effectively, but you will have to troubleshoot some common issues.


How to Troubleshoot SNMP Issues

Do you have a nagging SNMP problem that is reducing your network visibility? Do you spend hours trying to find the cause because you're not sure where to look? You're not alone. Finding and solving problems in your SNMP implementation can be a difficult task.

  • MIB files
  • Traps
  • Firewalls
  • IP routing
  • And more...
