Configuring an SNMP Network

About SNMP "Networks"

In an SNMP network, KMC Commander acts as an SNMP manager, gathering data points from agents (software modules inside devices such as routers, data servers, workstations, printers, and other IT devices) and triggering actions.

Note: Unlike BACnet, only one SNMP device is added to the “network” during discovery according to the information entered. For multiple SNMP devices, create multiple SNMP “networks.” For example, if the devices are all the same (e.g., four routers of the same model), the MIB file would be the same, but the IP address would be different for each one and would require four different “networks.”

Configuring

For an overview, watch the video below. For details, consult the following written information.

  1. In Settings > Protocols, upload the manufacturer's MIB file for the desired device. (See SNMP MIB Files in Configuring Protocol Settings.)

    Note: MIB (Management Information [data]Base) files contain data points describing the parameters of a particular device. The MIB file should be provided by the device manufacturer, and the file is uploaded to the manager (KMC Commander) so that the manager can decipher received data from the device.

  2. Go to Networks Explorer , then Networks.

  3. Select Configure New Network to go to the Configure Network page.

  4. For Protocol, select SNMP.

  5. Choose the SNMP Protocol Version used:

    • v1 (simplest, oldest, and least secure).

    • v2c (has additional features and the largest installed base)

    • v3 (most secure, the current standard, and recommended for use whenever possible)

  6. Enter the network's Name.

  7. Enter the Device IP Address.

  8. Optionally, enter any Subtree(s).

  9. Enter the number for the Destination Port and Trap (notifications) Port if needed. (See the device’s instructions.)

    Note: The Destination Port (default 161) is the port in the SNMP agent (the device) that receives requests from the manager. The Trap Port (default 162) is the port in the manager (KMC Commander) that receives unsolicited notifications from the agents.

  10. Select and enter user and security information as needed.

    Note: Security settings are typically found in the SNMP device’s documentation or web management page. Use the highest security supported by the device (Auth Priv being the highest, with required authentication of users and encryption of messages). If the device documentation specifies only one read or one write password but supports v3 Auth Priv, try using the same password for both Auth and Privacy fields. If there is trouble connecting to a v3 device, and the documentation does not specify an Auth or Priv protocol, try switching one or both of those protocols.

  11. Select Save.

  12. Continue with Configuring Devices.
