Recommended Instance Types

Resource Group

The resource group is a container that holds all the resources for a solution.

To create a resource group in Azure, refer to Create a resource group topic in the Azure Documentation.

Virtual Network

Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. VNet enables many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks.

For V Series 2 configuration, you can only configure the GigaVUE fabric components in a Centralized VNet only. In case of a shared VNet, you must select a VNet as your Centralized VNet for GigaVUE fabric configuration.

To create a virtual network in Azure, refer to Create a virtual network topic in the Azure Documentation.

Subnets for VNet

The following table lists the two recommended subnets that your VNet must have to configure the GigaVUE Cloud components in Azure.

You can add subnets when creating a VNet or add subnets on an existing VNet. Refer to Add a subnet topic in the Azure Documentation for detailed information.

Subnet	Description
Management Subnet	Subnet that the GigaVUE-FM uses to communicate with the GigaVUE V Series Nodes and Proxy.
Data Subnet	A data subnet can accept incoming mirrored traffic from agents to the GigaVUE V Series Nodes or be used to egress traffic to a tool from the GigaVUE V Series Nodes. There can be multiple data subnets. ■   Ingress is VXLAN from agents ■   Egress is either VXLAN tunnel to tools or to GigaVUE HC Series tunnel port, or raw packets through a NAT when using NetFlow. Note:  If you are using a single subnet, then the Management subnet will also be used as a Data Subnet.
Tool Subnet	A tool subnet can accept egress traffic to a tool from the GigaVUE V Series Nodes. There can be only one tool subnet. ■   Egress is either VXLAN tunnel to tools or to GigaVUE HC Series tunnel port, or raw packets through a NAT when using NetFlow.

Network Interfaces (NICs) for VMs

When using G-vTAP Agent as the traffic acquisition method, for the G-vTAP Agents to mirror the traffic from the VMs, you must configure one or more Network Interfaces (NICs) on the VMs.

■

Single NIC—If there is only one interface configured on the VM with the G-vTAP Agent, the G-vTAP Agent sends the mirrored traffic out using the same interface.

■

Multiple NICs—If there are two or more interfaces configured on the VM with the G-vTAP Agent, the G-vTAP Agent monitors any number of interfaces but has an option to send the mirrored traffic out using any one of the interfaces or using a separate, non-monitored interface.

Network Security Groups

A network security group defines the virtual firewall rules for your VM to control inbound and outbound traffic. When you launch GigaVUE-FM, GigaVUE V Series Proxy, GigaVUE V Series Nodes, and G-vTAP Controllers in your VNet, you add rules that control the inbound traffic to VMs, and a separate set of rules that control the outbound traffic.

To create a network security group and add in Azure, refer to Create a network security group topic in the Azure Documentation.

It is recommended to create a separate security group for each component using the rules and port numbers.

In your Azure portal, select a network security group from the list. In the Settings section select the Inbound and Outbound security rules to the following rules.

Network Security Groups for V Series 2 Node

Virtual Network Peering

Virtual network peering enables you to seamlessly connect two or more Virtual Networks in Azure. Virtual Network Peering is only applicable when multiple Virtual Networks are used in a design. Refer to Virtual Network Peering topic in Azure documentation for more details.

Access control (IAM)

You must have full resource access to the control the GigaVUE cloud components. Refer to Check access for a user topic in the Azure documentation for more details.

To add a role assignment, refer to Steps to assign an Azure role.
