Configure GigaVUE Fabric Components in OpenStack

You can use your own OpenStack orchestration system to deploy GigaVUE fabric nodes and use GigaVUE-FM to configure the advanced features supported by these nodes. These nodes register themselves with GigaVUE-FM using the information provided by your OpenStack orchestration system. Once the nodes are registered with GigaVUE-FM, you can configure monitoring sessions and related services in GigaVUE-FM. Health status of the registered nodes are determined by the heartbeat messages sent from the respective nodes.

Recommended Instance Type

The following table lists the recommended instance type for deploying the fabric components:

Fabric Component Machine type
GigaVUE V Series Node

m1.medium
GigaVUE V Series Proxy m1.small
UCT-V Controller m1.small

Keep in mind the following when deploying the fabric components using third party orchestration in integrated mode:

  • In the above mentioned case, the Traffic Acquisition Tunnel MTU is set to the default value 1500. To edit the Traffic Acquisition Tunnel MTU, select the monitoring domain and click on the Edit Monitoring Domain option. Enter the Traffic Acquisition Tunnel MTU and click Save.
  • When you deploy the fabric components using 3rd party orchestration, you cannot delete the monitoring domain without unregistering the registered fabric components.
  • You can use OpenStack Orchestrator for GigaVUE Visibility Node configuration only using V Series 2 nodes.

  • GigaVUE V Series Node must have a minimum of two Networks Interfaces (NIC) attached to it, a management NIC and a data NIC. You can add both these interfaces when deploying the GigaVUE V Series Node in OpenStack.

In your OpenStack dashboard, you can configure the following GigaVUE fabric components:

    3. Restart the UCT-V Controller service.
      $ sudo service uctv-cntlr restart

    Assign Static IP address for UCT-V Controller

    By default, the UCT-V Controller gets assigned an IP address using DHCP. If you wish to assign a static IP address, follow the steps below:

    1. Navigate to /etc/netplan/ directory.
    2. Create a new .yaml file. (Other than the default 50-cloud-init.yaml file)
    3. Update the file as shown in the following sample:
      Copy
      network:
              version: 2
              renderer: networkd
              ethernets:
                      ens3:
                              addresses:
                                      - <IP address>
                              gateway: <IP address>
                      ens4:
                              addresses:
                                      - <IP address>
                              gateway: <IP address>
                      ens5:
                              addresses:
                                      - <IP address>
                              gateway: <IP address>
    4. Save the file.
    5. Restart theUCT-V Controller service.

      $ sudo service uctv-cntlr restart

    The deployed UCT-V Controller registers with the GigaVUE-FM. After successful registration the UCT-V Controller sends heartbeat messages to GigaVUE-FM every 30 seconds. If one heartbeat is missing ,the visibility node status appears as 'Unhealthy'. If more than five heartbeats fail to reach GigaVUE-FM, GigaVUE‑FM tries to reach the UCT-V Controller and if that fails as well then GigaVUE‑FM unregisters the UCT-V Controller and it will be removed from GigaVUE‑FM.

Configure UCT-V in OpenStack

UCT-V should be registered via the registered UCT-V Controller and communicates through PORT 8891.

Note:  Deployment of UCT-V Agents through a third-party orchestrator is supported on Linux and Windows platforms. Refer to Linux UCT-V Installation and Windows UCT-V Installation for detailed information.

To register UCT-V using a configuration file:

  1. Install the UCT-V in the Linux or Windows platform. For detailed instructions, refer to Linux UCT-V Installation and Windows UCT-V Installation.

  2. Log in to the UCT-V.
  3. Create a local configuration file and enter the following user data.
    • /etc/gigamon-cloud.conf is the local configuration file in Linux platform.
    • C:\ProgramData\uctv\gigamon-cloud.conf is the local configuration file in Windows platform.

    Copy
    Registration:
        groupName: <Monitoring Domain Name>
        subGroupName: <Connection Name>
        user: <Username>
        password: <Password>
        remoteIP: <IP address of the UCT-V Controller 1>, 
               <IP address of the UCT-V Controller 2>
               
        sourceIP: <IP address of UCT-V> (Optional Field)
        remotePort: 8891

    • User and Password must be configured in the User Management page. Refer to Configure Role-Based Access for Third Party Orchestration for more detailed information. Enter the UserName and Password created in the Add Users Section.

    • If you are using multiple interface in UCT-V and UCT-V Controller is not connected to the primary interface, then add the following to the above registration data:
      localInterface:<Interface to which UCT-V Controller is connected>
  4. Restart the UCT-V service.
    • Linux platform: 
      $ sudo service uctv restart
    • Windows platform: Restart from the Task Manager.

Note:  You can configure more than one UCT-V Controller for a UCT-V, so that if one UCT-V Controller goes down, the UCT-V registration will happen through another Controller that is active.

The deployed UCT-V registers with the GigaVUE-FM through the UCT-V Controller. After successful registration the UCT-V sends heartbeat messages to GigaVUE-FM every 30 seconds. If one heartbeat is missing, UCT-V status appears as 'Unhealthy'. If more than five heartbeats fail to reach GigaVUE-FM, GigaVUE‑FM tries to reach the UCT-V and if that fails as well then GigaVUE‑FM unregisters the UCT-V and it will be removed from GigaVUE‑FM.

Keep in mind the following when upgrading the GigaVUE-FM to 6.1.00 or higher version (when using third party orchestration to deploy fabric components):

When upgrading GigaVUE-FM to any version higher than 6.0.00 and if the GigaVUE V Series Nodes version deployed in that GigaVUE-FM is lower than or equal to 6.0.00, then for the seamless flow of traffic, GigaVUE-FM automatically creates Users and Roles in GigaVUE-FM with the required permission. The username would be orchestration, and the password would be orchestration123A! for the user created in GigaVUE-FM. Ensure there is no existing user in GigaVUE-FM, with the username orchestration.

Once the upgrade is complete, it is recommended that the password be changed on the Users page. Refer to Configure Role-Based Access for Third Party Orchestration for detailed steps on how to change password in the user page.
