Configure GigaVUE Fabric Components using GCP

This section provides step-by-step information on how to register GigaVUE fabric components using Google Cloud Platform (GCP) or a configuration file.

Minimum Requirements

The following table lists the minimum requirements for deploying the fabric components:

Fabric Component Machine type
GigaVUE V Series Node
  • c2-standard-4 for 2 interfaces
  • c2-standard-8 for 3 interfaces
GigaVUE V Series Proxy e2-micro
UCT-V Controller e2-micro

Keep in mind the following when deploying the fabric components using GCP:

  • Ensure that the Traffic Acquisition Tunnel MTU is set to the default value of 1450 when using IPv4 tunnels or 1430 when using IPv6 tunnels. 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 value and click Save.
  • For successful registration of fabric components, firewall rules must be configured to open ports 443 and 8891. Refer to Use VPC firewall rules topic in GCP documentation for more detailed information on how to configure firewall rules.
  • When you deploy the fabric components using third party orchestration, you cannot delete the monitoring domain without unregistering the registered fabric components.
  • You can also create a monitoring domain under Third Party Orchestration and provide the monitoring domain name and the connection name as groupName and subGroupName in the registration data. Refer to Create Monitoring Domain for more detailed information on how to create monitoring domain under third party orchestration.
  • User and Password provided in the registration data 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.
  • When launching an instance, if you wish to access the instance using a private key, you will have add the key to the ssh key. The default password is gigamon.
  • You can also upload custom certificates to GigaVUE V Series Nodes, , GigaVUE V Series Proxy, and UCT-V Controller using your own cloud platform when deploying the fabric components. Refer to Install Custom Certificate for more detailed information.

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

  • 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 fabric component 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.

    The UCT-V Controller deployed in GCP appears on the Third Party Orchestration Monitoring Domain page of GigaVUE-FM.

    Configure UCT-V in GCP

    Note:  Deployment of GigaVUE fabric components through a third-party orchestrator is supported on Linux and Windows platforms.

    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.

    Register GigaVUE V Series Node and GigaVUE V SeriesProxy after Instance Launch

    To register GigaVUE V Series Node and GigaVUE V Series Proxy after launching the virtual machine using a configuration file, follow the steps given below:

    1. Log in to the GigaVUE V Series Node or Proxy.
    2. Create a local configuration file (/etc/gigamon-cloud.conf) and enter the following user data.
      Copy
      Registration:
          groupName: <Monitoring Domain Name>
          subGroupName: <Connection Name>
          user: <Username>
          password: <Password>
          remoteIP: <IP address of the GigaVUE-FM> or <IP address of the Proxy>
          remotePort: 443
      • You can register your GigaVUE V Series Nodes directly with GigaVUE‑FM or you can use V Series proxy to register your GigaVUE V Series Nodes with GigaVUE‑FM. If you wish to register GigaVUE V Series Nodes directly, enter the remotePort value as 443 and the remoteIP as <IP address of the GigaVUE‑FM> or if you wish to deploy GigaVUE V Series Nodes using V Series proxy then, enter the remotePort value as 8891 and remoteIP as <IP address of the Proxy>.
      • User and Password must be configured in the User Management page. Refer to Configure Role-Based Access for Third Party Orchestrationfor Third Party Orchestration for more detailed information. Enter the UserName and Password created in the Add Users Section.
    3. Restart the GigaVUE V Series node or proxy service. 
      • V Series node:
        $ sudo service vseries-node restart
      • V Series proxy:
        $ sudo service vps restart

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

    Note:  When the GigaVUE V Series Node is stopped or terminated from the GCP, it does not send any unregistration request and GigaVUE-FM will unregister the V Series Node soon after.

    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 are 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.

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