Reserve Your Seat TodaySNMP (Simple Network Management Protocol) was originally created in 1988 as a short-term solution to manage growing networks. It has grown beyond its roots to play an important role in remote alarm monitoring of telecommunications networks. SNMP can do a lot to make your network alarm monitoring more cost-effective and your network more reliable - if you clearly identify your network monitoring goals and have the right tools to achieve them.
Our SNMP PDF guidebook will give you fast, specific answers to help make SNMP monitoring work in your network:
Trap messages are the main form of communication between an SNMP Agent and an SNMP Manager. They are used to inform an SNMP manager when an important event happens at the Agent level. Traps are perfect for reporting alarms to a manager, being almost instantanious rather than waiting for a status request from the manager.
A common SNMP network monitoring application will look something similar to this, with SNMP enabled devices communicating alarms directly to your SNMP Master, and Non-SNMP enabled devices communicating alarms to an SNMP enabled RTU (Remote Telemetry Unit), which then relays the alarms up to the Master.
Specific SNMP appplication drawings and use cases can be found in our SNMP tutorial PDF.
Contacts to Traps
The most common use case for SNMP is receiving notifications when equipment goes down or an alarm goes off. This is a reactive use case, where an operator notified of an alarm or disturbance can quickly address the issue.
Traps to Contacts
Another way SNMP is used is to set up automatic actions to be taken via relays when traps are recieved. A common example of this is the startup of a generator when a powerloss is detected.
There are three different versions of SNMP currently available, each with their own benefits and drawbacks. Knowing which version you'll need to use is key when setting up a new SNMP system. Buying a brand new V3 solution with all the latest features can come back to bite you if you haven't considered your compatibility needs.
