Keep in mind the following when deploying the fabric components using generic mode:

  • 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.
  • Before deploying the monitoring session ensure that the appropriate Traffic Acquisition Tunnel MTU value is set. Otherwise, the monitoring session must be un-deployed and deployed again.
  • 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.
  • 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.
  • When creating virtual machine for deploying the fabric components in Azure, SSH public key must only be used as the Authentication type in Azure.

Prerequisites

GigaVUE V Series Node must have a minimum of two Networks Interfaces (NIC) attached to it, a management NIC and a data NIC with Accelerated Networking enabled.

When creating a virtual machine for GigaVUE V Series Node using CLI, Management NIC and Data NIC can be attached at the time of the virtual machine creation. However, if you are using Azure GUI to create the virtual machine for GigaVUE V Series Node, then the data NIC can only be attached after creating the virtual machine. Refer to the following topics for more detailed information on how to create GigaVUE V Series Node with Management and Data NIC using CLI or Azure GUI:

NOTE:

  • Accelerated Networking must be enabled in the Data NIC only when deploying GigaVUE V Series Nodes using Third Party Orchestration.
  • Accelerated Networking is not required for Management NIC.

Create GigaVUE V Series Node with Management and Data NIC Attached using CLI

Create management NIC: 

az network nic create -g <resource group> --vnet-name <VNet Name> --subnet <Subnet name> -n <Mangement NIC Name>

Create data NIC with Accelerated Networking enabled: 

az network nic create -g <resource group> --vnet-name <VNet> --subnet <Subnet> -n <Data NIC> --accelerated-networking true

Create GigaVUE V Series Node virtual machine using the above NICS:

az vm create --resource-group <Resource group> --size <Standard_D4s_v4/Standard_D8S_V4> --name <GigaVUE V Series Node> --admin-username gigamon --generate-ssh-keys --image gigamon-inc:gigamon-gigavue-cloud-suite:vseries-node:6.8.00 --plan-name vseries-node --plan-product gigamon-gigavue-cloud-suite --plan-publisher gigamon-inc --nics <Management NIC and Data NIC>

    • GigaVUE V Series Node: 
      $ sudo service vseries-node restart
    • GigaVUE V Series Proxy: 
      $ sudo service vps restart

The deployed GigaVUE V Series proxy registers with the GigaVUE-FM. After successful registration, the GigaVUE 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 theGigaVUE V Series proxy and if that fails as well then GigaVUE‑FM unregisters the GigaVUE V Series proxy and it will be removed from GigaVUE‑FM.

Note:  When the GigaVUE V Series Node is stopped or terminated from the Azure, 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 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.
