SNMP

SNMP (Simple Network Management Protocol) is a widely used application-layer protocol for managing and monitoring network elements. It has been defined by the Internet Architecture Board under RFC-1157 for exchanging management information between network devices, and is part of the TCP/IP protocol.

SNMP agents must be enabled and configured so that they can communicate with the network management system (NMS). The agent is also responsible for controlling the database of control variables defined in the Management Information Base (MIB).

VersaSync’s SNMP functionality supports SNMP versions V1, V2c and V3 (with SNMP Version 3 being a secure SNMP protocol).

Note: In order to configure SNMP, you need ADMINISTRATOR rights.

To access the SNMP Setup screen:

  1. Navigate to MANAGEMENT > NETWORK: SNMP Setup. The SNMP screen will display:
  2. The SNMP screen is divided into 3 panels:

    1. The Main panel, which is subdivided into 3 displays:
      • SNMP V1/V2: This panel allows configuration of SNMP v1 and v2c communities (used to restrict or allow access to SNMP). This tab allows the configurations for SNMP v1 and v2c, including the protocols allowed, permissions and Community names as well as the ability to permit or deny access to portions of the network. Clicking on the “+” symbol in the top-right corner opens the SNMP V1/V2c Settings for Access Screen. See SNMP V1/V2c.
      • SNMP V3: This panel allows configuration of SNMP v3 functionality, including the user name, read/write permissions, authorization passwords as well as privilege Types and Passphrases. Clicking on the “+” symbol in the top-right corner opens the SNMP V3 Screen. See SNMP V3.
      • SNMP Traps: This panel allows you to define different SNMP Managers that SNMP traps can be sent to over the network. This allows for SNMP Managers in different geographical areas to receive the same SNMP traps that Managers in other areas also receive. Clicking the PLUS icon in the top-right corner opens the SNMP Traps Settings Screen. See also SNMP Traps and Setting Up SNMP Notifications.
    2. The Actions panel, which contains the Restore Default SNMP Configuration button.
    3. The SNMP Status panel, which offers:
      • An SNMP ON/OFF switch.
      • An Authentication Error Trap ON/OFF switch.
      • SysObjID—The System Object ID number. This is editable in the SNMP Status panel (see Configuring the SNMP Status).
      • Contact Information—The email to contact for service. This is editable in the SNMP Status panel (see Configuring the SNMP Status).
      • Location—The system location. This is editable in the SNMP Status panel (see Configuring the SNMP Status).
      • Description—A simple product description. This is not editable in the SNMP Status.
