Settings	Description
Refresh interval for VM target selection inventory (secs)	Specifies the frequency for updating the inventory of VMs in OpenStack.
Refresh interval for fabric deployment inventory (secs)	Specifies the frequency for updating the inventory of GigaVUE fabrics in OpenStack.
Number of UCT-Vs per V Series Node (applicable only for UCT-V based connections)	Specifies the maximum number of instances that can be assigned to the V Series node.
Number of hypervisors per V Series Node (applicable only for OVS mirroring)	Specifies the maximum number of hypervisors that can be assigned to the V Series node.
Refresh interval for UCT-V inventory (secs)	Specifies the frequency for discovering the UCT-Vs available in the project. This is applicable for UCT-Vs only.
OVS Mirror tunnel range start	Specifies the startup range value of the OVS mirror tunnel ID. This is applicable for UCT-V OVS Agents only.
OVS Mirror tunnel range end	Specifies the closing range value of the OVS mirror tunnel ID. This is applicable for UCT-V OVS Agents only.
Traffic distribution tunnel range start	Specifies the start range value of the tunnel ID.
Traffic distribution tunnel range end	Specifies the closing range value of the tunnel ID.
OVS Agent Traffic when V Series is down	Enable this option to stop the OVS Agent from sending the traffic to the V Series node. You can stop the traffic either manually or automatically. Refer to Shutdown or Restart of OVS traffic to know more about the manual or automatic shut down and restart.
Traffic distribution tunnel MTU	Specifies the MTU value for the traffic distribution tunnel.
Reboot threshold limit for UCT-V Controller down	Specifies the number of times GigaVUE-FM tries to reach UCT-V Controller, when the UCT-V Controller moves to down state. GigaVUE-FM retries every 60 seconds.

Shutdown or Restart of OVS traffic

GigaVUE‑FM allows you to stop or restart the traffic through OVS Mirroring based on the availability of V Series node.

GigaVUE‑FM helps you to stop the traffic when the V Series node is unreachable or unrecoverable, and restart it when the GigaVUE V Series Node is reachable again in the following ways:

■

Manual shutdown or restart of OVS traffic

■

Automatic shutdown or restart of OVS traffic

Manual shutdown or restart of OVS traffic

The traffic sent from the OVS Mirroring Agent can be manually stopped and started.

To shut down or restart the OVS traffic manually, follow these steps:

1.

Go to Inventory > VIRTUAL > OpenStack, and then click Settings

2.

Click the Settings drop-down, and then select Advanced Settings.

3.

Enable the check box OVS Agent Traffic when V Series is down.

4.

Click the Fabric tab.

5.

Select the V Series node.

6.

Click the Actions drop-down list and select Shut down OVS Traffic or Restart OVS Traffic as required.

Note:  You can view the Shut down OVS Traffic or Restart OVS Traffic options only when you enable the check box OVS Agent Traffic when V Series is down in the Advanced Settings.

Automatic shutdown or restart of OVS traffic

When the GigaVUE V Series node is deleted or changed to an unrecoverable state in the OpenStack platform, GigavUE-FM performs the action as explained in the following table:

V Series node Status in OpenStack	Action in GigaVUE‑FM	Action in GigaVUE‑FM when you enable the option
When a V Series node is deleted from the OpenStack platform	GigaVUE‑FM automatically sets the status of that V Series node as terminated.	In the Advanced Settings, when the OVS Agent Traffic when V Series is down checkbox is enabled, GigaVUE‑FM removes the source interfaces of OVS Mirroring agent
When a V Series Node is changed to a stopped or shutoff state in Openstack	GigaVUE-FM Health monitoring module tries to start the V Series node. If unsuccessful after two attempts, GigaVUE-FM considers the V Series node to be unrecoverable.	In the Advanced Settings, when the OVS Agent Traffic when V Series is down checkbox is enabled, GigaVUE‑FM removes the source interfaces of OVS Mirroring agent.
When a V Series node is in an active state and its connection to GigaVUE‑FM is restored	GigaVUE-FM Health Monitoring module determines V Series Node is in a healthy state.	In the Advanced Settings, when the OVS Agent Traffic when V Series is down checkbox is enabled, GigaVUE‑FM adds the source interfaces of the OVS Mirroring agent and restarts the OVS traffic.
