This chapter describes what is a flow and how to quickly view the packet drops and packet errors that causes the flow to be unhealthy.

Considering the system resources needed for its calculation, flows is disabled by default in GigaVUE‑FM. However, you can enable flows if required. For larger deployments, exercise caution before enabling flows.

To enable Flows:

  1. On the left navigation pane, click and select System > Preferences.
  2. Click Edit.
  3. On the Edit Preferences page, under Flows, change the status to Enabled.

Note:  You cannot disable flows once it is enabled. Contact Customer Support to disable Flows.
