WebNMS SNMP Utilities 5

The WebNMS SNMP Utilities is a SNMP network management utility consist of set of cross-platform applications and applets for web based network management. These utilities can be used for device, element, application, and system management. These tools can communicate and interact with any SNMP-enabled device. Also it is very helpful for debugging and testing. The SNMP Utilities has a simple and intuitive graphic user interface that allows you to perform various functions in a mouse-click.

WebNMS SNMP Utilities consists of the following tools: MIB Browser, SNMP Trap Viewer, SNMP Proxy Configurator, SNMP Decoder, Proxy Forwarder, and i18N Editor.

Key Features of WebNMS SNMP Utilities

  • Support for SNMPv1, SNMPv2c, and SNMPv3.
  • Support UDP / TCP Network protocol for communication.
  • SNMPv3 security as defined in USM and VACM.
  • MibBrowser supports CFB-AES-128 along with CBC-DES privprotocol.
  • Support for Traps and INFORMS.
  • Improved and enhanced MibBrowser UI tool.
  • Alert the Operator/Administrator about the status of the device through e-mail.
  • Database support for storing MIBs/SNMPv3 configuration data.
  • SNMP table data viewer.
  • Real-time graphing components.
  • MIB definitions as in SMIv1 and SMIv2 formats.
  • Supports parsing of MIB files.
  • IPv6 support in MibBrowser at protocol level.
  • Privprotocl CFB-AES-128 and CBC-DES is supported in ProxyForwarderConfigurator/ProxyForwarder.
  • SNMP Applet Server (SAS) to communicate between applets and managed devices.

MibBrowser

WebNMSMibBrowser is a complete SNMP MibBrowser that enables loading, browsing, and searching MIBs, walking the MIB tree, and performing all other SNMP-related functions. MibBrowser also enables viewing and operating the data available through an SNMP agent in a managed device.

Features of WebNMS MibBrowser

  1. MibBrowser supports UDP/TCP communication with respective agents.
  2. SNMP operations like GET and GETNEXT can be performed by right clicking each node of the MIB tree. Definition of each node for a particular object can also be viewed.
  3. Enables to perform the basic SNMP operations, such as GET, GETNEXT, GETBULK, and SET.
  4. Display the output of any snmp operations in a tabular fashion with oid and value as columns.
  5. Supports multi-varbind requests.
  6. Enables real-time plotting of SNMP data in a graph. Line graph and bar graph are the two types of graphs that are currently supported.
  7. Provides a user-friendly view of SNMP table data. The table data can be viewed in a separate window called SNMP Table Panel.
  8. Enables to view the incoming traps using Trap Viewer. It also allows parsing of traps.
  9. Supports internationalization. This feature deploys the applications and applets developed using the WebNMS SNMP Utilities in various languages without altering the code.
  10. Enables loading of MIBs at startup.

Trap Viewer

Trap Viewer is a graphical tool to view the traps received from one or more SNMP agents. Trap Viewer can listen to one or more port at a time and the traps can be sent from any host. Trap Viewer can handle inform requests as well. Inform requests can be sent from a manager to another manager. Trap Viewer can receive and display inform messages. Trap Viewer is used for

  • Receiving Traps
  • Receiving INFORMS
  • Parsing Traps
  • Editing Traps
  • Displaying Traps received
  • Trap Logging in Text and XML formatt.
  • Alert the Operator/Administrator about the status of the device through e-mail.

SNMP Proxy Forwarder

SNMP Proxy Forwarder is a multilingual SNMP tool which translates SNMPV3 requests for SNMPv1/v2c agents. Basically, it converts all incoming SNMPv3 requests from the manager to a SNMPv1/v2c request based on the agent type. It then forwards this request to the appropriate agent and gets the response. The response is reconstructed as SNMPv3 response and sent back to the manager.

The SNMP Proxy Forwarder tool supports multiple SNMPv3 mangers to communicate with multiple SNMPv1/v2c agents. In such situations, requests from a manager is routed to the appropriate agent and the received response is again given to the same manager.

SNMP Proxy Forwarder Configurator

The Proxy Forwarder Configuration tool is used to store the details on the agents, users and the Vacm details. It has a powerful and intuitive user interface which makes the task of making a SNMPv3 query much easier. The Proxy Forwarder Configuration tool supports the User Based Security Model (USM) and the View Based Access Control Method (VACM) of the SNMPv3.

The Proxy Forwarder Configuration tool comes with powerful wizards which allows to configure the necessary information needed before making a SNMPv3 request.

  • Agent Configuration - allows to configure various agent hosts to be queried.
  • User Configuration - allows to configure various security levels for the users. Supports CFB-AES-128 and CBC-DES Privacy Protocol.
  • VACM Configuration - allows to configure the VACM details. The wizard also has a table view in which the VACM details can be configured in the corresponding tables.

SNMP Decoder

The SNMP Decoder helps in debugging the information by interpreting the encoded output from any SNMP agent. The Debug pane is used to show the PDU that is sent from the manager and the response PDU that is got from the agent.

The Snmp Decoder is used to decode the SNMP debug messages. If the debug message was stored in a file, the decoding can be done by loading the file. The debug message in the Debug window can be saved and can be loaded in the Decoder window.

i18N Editor

The i18N Editor enables localization of MIB Browser components.
