SNMP Traps

The SNMP Traps page shows the configuration settings applied to the devices managed by GigaVUE‑FM. This page also allows you to configure the settings that need to be applied to all the devices managed by the GigaVUE‑FM instance.

When the GigaVUE‑FM instance starts, the following SNMP traps are enabled by default, for all the devices:

  • Link Status or Speed Change
  • Module Change
  • Fan Status Change
  • Power Supply Status Change
  • Inline Bypass Forwarding State Change

The traffic health state of the ports and devices is computed based on the SNMP traps. Therefore, in addition to the above traps, the SNMP traps that are used to determine the health status of the ports and devices are also enabled by default.

For optimum performance of GigaVUE-FM, SNMP trap processing is disabled during the first config refresh cycle, as in the following cases:
  • When GigaVUE‑FM starts or restarts.
  • When node comes back after being down.

    • Note:  You must audit the SNMP trap list again to ensure that the System Reset Trap is enabled on all devices.

Traffic Health State Based on SNMP Traps

GigaVUE-FM determines the traffic health state of the devices and ports as follows:

  • If GigaVUE-FM receives any of the traffic health related traps mentioned above: Port state is set to yellow or red.
  • If no further traps are received within the configured interval, which is 5 minutes: Port state is set to green.
    • For utilization thresholds, the health status will be reset as soon as GigaVUE-FM receives clear trap from the device.
  • When a new device is added to GigaVUE-FM, the traps that determine the health status of the ports and devices are enabled, by default. However, if some of these traps are disabled in the device, then GigaVUE-FM cannot determine the health status.
  • When GigaVUE-FM reboots, the traffic health status of all the devices will be cleared and will be recomputed based on the subsequent traps received by GigaVUE-FM.

Configure SNMP Traps

On the left navigation pane, click to access SNMP Traps and select System > SNMP Traps.

1 SNMP Traps Page

The SNMP Traps page allows you to configure the following:

■   Enable/disable all the traps for all the devices using the Enable All and Disable All options.
■   Enable/disable specific traps for all the devices using the Enable and Disable options for each of the traps.
■   Retain device settings for all the traps using the Retain Device Settings for All Traps option.

To configure the SNMP traps:

1.   Click the Edit button on the top right corner.
2. Configure the required setting. For example, to retain the individual device level setting for all traps, select the Retain Device Setting for All Traps checkbox.

Note:  You can also retain the device settings for specific traps by selecting the Retain Device Setting checkbox against the required traps.

3. Click Save

With this functionality, the following configuration settings are applied to all the devices:

■   Specific configuration type changes
■   Audit configuration changes

Note:  If a new device is added to GigaVUE‑FM, then the global configuration setting is applied to the new device. If for some reason, the configuration setting is not applied to a device, then an event is raised with the appropriate details in the Events page.

If a trap has been forcefully enabled/disabled on a device because of the global configuration setting, then an event is raised with the appropriate details in the Events page.
