Using SNMP Monitoring

You can configure the CTERA Edge Filer for monitoring using SNMP. This enables you to gather a wide range of information about the devices.

SNMP can be used with all CTERA Edge Filers. SNMP v1, v2c, and v3 are supported.

CTERA Edge Filer includes Net-SNMP. For details, refer to http://www.net-snmp.org.

Information is collected for the following MIBS:

• MIB-II (IF-MIB): Basic description of the monitored system, such as the system name, uptime, and network interfaces. For details of this MIB, refer to http://www.net-snmp.org/docs/mibs/interfaces.html and http://www.net-snmp.org/docs/mibs/ifMIBObjects.html.
• HOST-RESOURCES-MIB: Computer management information, hardware and software configuration, such as information regarding system initialization, processes, storage, memory, processors, and devices. For details of this MIB, refer to http://www.net-snmp.org/docs/mibs/host.html.
• UCD-SNMP-MIB: System performance data, such as system statistics and performance. For details of this MIB, refer to http://www.net-snmp.org/docs/mibs/ucdavis.html.
• For an H-Series CTERA Edge Filer running on an HPE server, you can use the System Insight Manager MIBs to monitor the HPE ProLiant server: https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_53293d026fb147958b223069b6.

The MIB files are available from the CTERA Knowledge base download center under Third-Party Products: SNMP MIBs.
The MIBs are stored on the SNMP server on the CTERA Edge Filer. You can monitor the CTERA Edge Filer MIBs using a management tool, such as the tool from https://www.paessler.com/.

Setting Up SNMP Monitoring on the CTERA Edge Filer

To set up SNMP monitoring:

1. In the Configuration view, select System > SNMP in the navigation pane.
   The SNMP page is displayed.
   
2. Slide Enable SNMP on.
   
3. Configure the following settings:
   SNMP Port – The default is TCP 161.
   Note

   SNMP Engine ID is defined automatically based on the MAC address and cannot be changed.

   Read Community – Configure as Read-Only. The SNMP Read-Only Community String is like a password. It is sent along with each SNMP Get-Request and allows or denies access to the device.
4. If you are using SNMP v3, slide Enable SNMPv3 on.
   
   • Enter a user name, authentication password, and the privacy password, which must be a minimum of 8 characters.
5. If you made any changes, either click Save or click Revert to revert to the last saved configuration.
