Simple Network Management Protocol (SNMP) is a standard protocol that is commonly used today in many networks. The SNMP protocol is great for integrating classic telecom telemetry with modern IP-based network management. It's an open-standard protocol that's flexible enough to describe almost anything.
The one hitch is, some of your most crucial network infrastructures are not built for SNMP, such as legacy or proprietary gear. To integrate your infrastructure elements into your SNMP alarm management, you need to install SNMP proxy devices at your remote sites.
Many telemetry network managers - perhaps you - are faced with the task of collecting data using SNMP agents from non-SNMP devices and reporting that information to an SNMP manager. The right tool for this job is an SNMP proxy agent device. Not only that, but it also needs to be reliable to ensure the safety of your most critical gear.
A proxy agent is a device that is able to convert one protocol to another. In the case of the SNMP proxy agent, the "proxy" is converting contact closures to SNMP traps. Therefore, you're viewing contact closures "by proxy" as SNMP messages.
This is necessary when you have pieces of equipment that use different protocols. The proxy agent acts as a translator or "middleman" between devices.
Here are some situations where having an SNMP proxy can be valuable:
Before you begin designing your SNMP-based network monitoring system, you should keep the following concerns in mind. By using these points as a check-list, you will be able to appropriately design a system that is a perfect fit for your network.
While a proxy agent is used to convert one protocol to the next, some proxy agents can provide additional functionality.
The NetGuardian 832A G5 by DPS Telecom is a great option when looking for an SNMP Proxy. The 832A G5 is a high capacity RTU that features 32 discretes, 8 analogs, 8 controls and reports alarms via SNMP v1, v2c or v3. This versatile RTU has expansion options to provide a perfect-fit solution and the slim design only requires 1 rack unit of space. The NetGuardian 832A G5 also features:
With the NetGuardian 832A G5, you are not only getting a great SNMP proxy agent, but you are also getting an RTU with a lot of additional functionality. It's a great choice if you also need to monitor sensors, operate controls and other RTU activities. It's important that all of your equipment can communicate properly.
The NetGuardian 832A G5 will make that happen. The combination of SNMP proxy agent and RTU provided by the NetGuardian 832A G5 will ensure that your sites will never go unmonitored or unprotected. If there is a problem, you will be the first to know, saving you valuable time and money.
If the NetGuardian 832A is not right for your needs, DPS Telecom offers a variety of RTUs with various configurations to fit a wide variety of industries, site sizes, and needs. Plus, DPS Telecom offers custom engineering for those companies that really need a unique product.
The bottom line is you simply cannot afford to monitor your non-SNMP equipment with SNMP Managers without an SNMP Proxy Agent. Don't leave your sites vulnerable to preventable damage and outages.
