SNMP tools have become network management essentials for any network admin, providing visibility into their network devices and infrastructure. Using an effective assortment of SNMP tools like SNMP Walker, SNMP Graph Tool, and windows SNMP Trap Receiver can help you build a proactive network management strategy. Join in as we discuss the basics of SNMP, different SNMP tools, and a list of free SNMP tools aiding in optimize your network performance.
Simple Network Management Protocol (SNMP) is an application layer-protocol for communication between network devices. SNMP allows various network devices such as routers, switches, gateways and more to communicate with each other, irrespective of the hardware or software type. As an IT administrator, using an SNMP toolcan be very useful for you to efficiently monitor and manage your network.
SNMP Network Managers: As a part of the Network Monitoring Software (NMS), the SNMP managers are responsible for the communication between SNMP agents.
Managed Components: These are SNMP enabled devices in your network which includes devices like switches, routers, servers, etc.
SNMP Agents: These are installed within the managed devices. They act as the gateway between the device and the SNMP Managers. They communicate with the external SNMP managers or agents to relay the status of local device.
SNMP MIB Database: The Management Information Database (MIB) within the managed components determine the communication between SNMP Manager and SNMP agents. MIB’s are hierarchical databases that defines the parameters for managed devices.
With the ever-growing scale of organizational networks, it is common to have a heterogeneous network environment. SNMP tools such as SNMP Walker tool and SNMP Browser tool, helps you to monitor any type of SNMP enabled device. The MIB database has a huge number of both private and standard vendor MIBs. In such a scenario, the OpUtils SNMP tools can be used to monitor such devices.
SNMP MIB Module Viewer tool, SNMP MIB Node Viewer tool, SNMP Community Checker, are few of the SNMP tools OpUtils has to offer. OpUtils built-in SNMP tools allows you to proactively monitor your network’s SNMP devices and MIB’s. Collate crucial information from various network devices with built in support for a wide range of MIB information modules using OpUtils.
Monitor networks, servers, switches, firewalls and printers in-depth using OpManager, a powerful, SNMP-based network monitoring solution by ManageEngine.
OpUtils’ free SNMP tools include MIB Tools such as ManageEngine MIB Browser. The SNMP MIB Browser tool is a network utility that enables you to load and browse MIBs and perform various operations. With MIB browser tool, you can perform all SNMP-related operations such as GET, GET-NEXT, GET-BULK, and SET. The above stated operations along with the SNMP MIB scanner can be performed on the specified agent in the MIB browser tool.
SNMP Graph utility of OpUtils software is a SNMP tool used to gather real time data and draws a graph for any SNMP IP node. SNMP Graph tool provides SNMP Graphing along with the MIB node information like OID, syntax, description and MIB node properties. The SNMP data to be polled should be of integer or unsigned integer data type (Counter, Gauge, or Time ticks). The SNMP Grapher is a part of the free SNMP tools by ManageEngine.
Many a times network engineers are aware of the MIB node but not sure of the OID and its properties. In such situations a SNMP tool like the MIB Node Viewer utility would be of great use. It accepts the node name or the OID as input and provides the complete information on the MIB node.
The MIB Module Viewer is a SNMP tool that provides a snapshot of a given MIB. It provides some general information on the MIB and also provides the defined attributes, total number of nodes, defined TCs, and the defined traps. It also provides the SMIv2 specific details.
The Community Checker utility of the OpUtils software scans the range of IP Addresses to get their SNMP read and write community strings based on the pre-defined set of default and standard community strings of the switches, routers, etc.
OpUtils’ Free SNMP Tools includes a Free SNMP Trap Receiver which collects, logs, and enable you to view and resolve the SNMP Traps in your network. SNMP Trap Collector, collects the SNMP Trap raised by network devices, which are significant network events relayed by the IP’s, interfaces, and other devices in your network. The SNMP traps are processed by the trap monitor and notified to you in the form of SNMP trap notifications. SNMP Trap Viewer allows you to view these traps.
