Troubleshoot Flexible Inline Flows

The flexible inline canvas provides you the ability to view the status of the flexible inline flow deployments, port statistics, and the details of the cluster-level maps used in the deployments. You can use these details to troubleshoot any issues or failures in your flexible inline flows.

The flexible inline canvas has the following tabs:

The Status tab provides details of the forwarding states of inline network. Click the required component that is part of the selected inline network to view the component’s properties. Refer to View the Forwarding States of Inline Networks.

It also provides the status of the components that are part of the selected inline network. Hover over the status to view the description.

Click the Show Stats/Hide Stats toggle button to view the Rx/Tx rate for the components that are part of the flexible inline flow deployment. Refer to the following figure for details.

Keep in mind the following points when you are viewing the details in the Status tab:

  • The ability to view the Rx/Tx rate for the components is supported only for GigaVUE-HC1, GigaVUE‑HC2, and GigaVUE‑HC3 devices.

  • The Rx/Tx rate for inline components are displayed in GigaVUE‑FM only for flexible inline deployments. In addition, the historical trends are not displayed in GigaVUE‑FM. However, you can view the Rx/Tx rate for classic inline components using the GigaVUE-OS CLI commands. For details, refer to the following topics in the GigaVUE-OS CLI Reference Guide:

    • show

    • ib pathway

    • inline tool group

    • inline tool

    • inline serial

    • inline network group

    • inline network

  • The Rx/Tx rate that is displayed is not for a map or a flexible inline flow, but it is a cumulative value that is shared across multiple maps and flexible inline flows.

  • The Rx/Tx rate for a GigaSMART group is a cumulative value for the traffic flowing between both a-b and b-a directions.

  • The Rx/Tx rate for OOB copy is supported only for single tool.

  • You cannot view the health status of GigaSMART.

  • The near real time data is not displayed for LED's health status and failover state representation of the inline component. The data gets updated during the GigaVUE‑FM configuration synchronization period. Alternatively, when the Rx/Tx rate for an inline component drops to zero, you can choose to refresh the Status tab to view the updated data.

The Statistics tab provides statistical information of the inline network ports, inline tool ports, and the virtual ports used in the selected inline network. It also provides the inline decryption session statistics for the inline network. The inline network, inline tools, and the ports aliases are displayed as clickable links. Use these links to access the quick view of the respective component. Refer to the following figure for details.

 

The Troubleshoot tab provides details about the device-level maps that are created for the selected inline network. The details include the source of the map, inline tools or inline tool groups used in the A to B and B to A directions, tool side and network side VLAN tags, and OOB copies. Click the required component to view its configuration details. It also provides details about the map statistics. In case of inline tool group, you can view the list of inline tools that are associated with the inline tool group. Click the required inline tool from the list to view its configurations. Refer to the following figure for details.

 

To troubleshoot any issue or failure in your flexible inline flow:

1.   From the flexible inline canvas, go to the Status tab to check the forwarding states of the required inline network.
2. Go to the Statistics tab to check the port statistics to ensure that there are no drops, errors, or discards.

Note:  Click the Statistics tab again to refresh the data.

3. Go to the Troubleshoot tab to check the required map configurations and isolate the issue.
