Create Ingress and Egress Tunnel (Third Party Orchestration)

Traffic from the GigaVUE V Series Node is distributed to tunnel endpoints in a monitoring session. A tunnel endpoint can be created using a standard L2GRE, VXLAN, UDPGRE, or ERSPAN tunnel.

Note:  GigaVUE-FM allows you to configure Ingress Tunnels in the Monitoring Session, when the Traffic Acquisition Method is UCT-V.

To create a new tunnel endpoint:

  1. After creating a new monitoring session, or click Actions > Edit on an existing monitoring session, the GigaVUE-FM canvas appears.
  2. In the canvas, select New > New Tunnel, drag and drop a new tunnel template to the workspace. The Add Tunnel Spec quick view appears.
  3. On the New Tunnel quick view, enter or select the required information as described in the following table.

  4. Click Save.

To delete a tunnel, select the required tunnel and click Delete.

To apply threshold template to Tunnel End Points, select the required tunnel end point on the canvas and click Details. The quick view appears, click on the Threshold tab. For more details on how to create or apply threshold template, refer to Monitor Cloud Health topic.

Tunnel End Points configured can also be used to send or receive traffic from GigaVUE HC Series and GigaVUE TA Series. Provide the IP address of the GigaVUE HC Series and GigaVUE TA Series as the Source or the Destination IP address as required when configuring Tunnel End Points.

After configuring the tunnels and deploying the monitoring session, you can view the names of egress tunnels configured for a monitoring session, on the Monitoring Session details page. The Egress Tunnel column displays the name of the egress tunnel configured for a particular monitoring session. When multiple egress tunnels are configured for a monitoring session, then the Egress Tunnel column displays the number of egress tunnels configured in that monitoring session. Hover over the number of egress tunnels to display the names of the egress tunnels used in that particular monitoring session.
