Configure Port Groups/Port-Profiles
GigaVUE-VM nodes use Port Groups (vSphere Standard Switch and vSphere Distributed Switch) for management, network, and tunneling traffic, as follows:
- One port group/port-profile for management communications with the GigaVUE-VM node.
- One port group/port-profile for network monitoring of traffic crossing the virtual switch.
- One port group/port-profile for the starting point of the GigaSMART tunnel used to forward virtual network traffic to the Gigamon Visibility Fabric nodes.
Before deploying GigaVUE-VM in a vSphere environment that uses the native standard switch implementation, you need to use the vSphere Client to configure port groups for management, tunneling, and network traffic. You select these port groups during deployment of the GigaVUE-VM node, so they must be configured before deploying the OVA file.
Note: It is important that the port group assigned to the GVM network ports are not uplinked.
The following table shows the GigaVUE-VM traffic and corresponding virtual switches used for port group/port-profile creation. Yes indicates that you can create a port group/port-profile for the GigaVUE-VM traffic, while No indicates no action is required.

Refer to the following sections for information on setting up Port Groups/Port-Profiles:

| • | Configure Port Group/Port-Profile for GigaVUE-VM Tunnel |
| • | Configure Port Group/Port-Profile for GigaVUE-VM Network |
Configure Port Group/Port-Profile for GigaVUE-VM Management
You can configure a port group/port-profile for GigaVUE-VM Management traffic using:
| • | vSphere Standard Switch |
| • | vSphere Distributed Switch |
In general, the Management port group must be connected to a dedicated out-of-band network to ensure access. See Best Practices for vSphere Integration.
For convenience, it is suggested that you use, PG_GVM_Management for the Management port group name to help you deploy multiple nodes using the GigaVUE-VM Bulk Deploy feature.
Configure Management Port Group for vSS Example
You can use the following steps as an example of how to configure a virtual standard switch (vSS) port group. This procedure shows how to configure the management port group on a vSS. This example is also applicable for configuring a vSS for the Tunnel port group.
| 1. | Log in to the vSphere client and add a vSphere Standard Switch to your Data Center, followed by populating it with Hosts and Network Adapters. Refer to the vSphere documentation for details. |
| 2. | Select the Host > Configuration > Networking inventory view. |
| 3. | Go to Add Networking and select New Port Group. |
| 4. | Supply the following Properties for the Management Port Group: |
|
Name |
Use a name that helps identify the purpose of the port group in GigaVUE-VM. For example, vss_PG_GVM_Management. |
||||||||||||
|
Number of Ports |
Optional. Either enter the number of ports in the field or use the scroll up-down button to enter the value. |
||||||||||||
|
VLAN Type |
Optional. Select one of the following:
|
| 5. | Click the Next button. |
| 6. | Click the Finish button. |
The new Network Port Group appears under the Standard Switch entry in the vSphere Client.
You will select the port groups for Management, but not for Network, that you created here in Step 3 of the GigaVUE-VM Bulk Deploy wizard.
Configure Port Group/Port-Profile for GigaVUE-VM Tunnel
You can configure a port group/port-profile for GigaVUE-VM Tunnel traffic using:
| • | vSphere Standard Switch |
| • | vSphere Distributed Switch |
In general, for optimal performance, you must maintain the IP interface on a dedicated VMNIC rather than sharing the same VMNIC as the Management or Network Ports. See Best Practices for vSphere Integration.
For convenience, it is suggested that you use, dvPG_GVM_Tunnel for the Tunnel port group name to help you deploy multiple nodes using the GigaVUE-VM Bulk Deploy feature.
Configure Tunnel Port Group for vDS Example
You can also use the following example to configure the Tunnel port group for the vSS. This procedure shows how to configure for a vDS:
| 1. | Log in to the vSphere Client and add a vSphere Distributed Switch to your Data Center, followed by populating it with Hosts and Network Adapters. Refer to the vSphere documentation for details. |
| 2. | Select the Networking inventory view. |
| 3. | Right-click on the Distributed Switch entry and select New Port Group. |
| 4. | Supply the following Properties for the Tunnel Port Group: |
|
Name |
Use a name that helps identify the purpose of the port group in GigaVUE-VM. For example, dvPG_GVM_Tunnel. |
||||||||||||
|
Number of Ports |
Optional. Either enter the number of ports in the field or use the scroll up-down button to enter the value. |
||||||||||||
|
VLAN Type |
Optional. Select one of the following:
|
| 5. | Click Next. |
| 6. | Click Finish. |
The new Tunnel Port Group appears under the Distributed Switch entry in the vSphere Client.
Configure Port Group/Port-Profile for GigaVUE-VM Network
You can configure a port group/port-profile for GigaVUE-VM Network traffic using vSphere Distributed Switch
For information on vSS configuration for Network traffic, see Create vMap using a vNIC on vSS.
Create vMap using a vNIC on vSS
When creating a vMap using a vNIC on vSS to monitor traffic, there are no additional actions to perform. The following occurs:
| • | GigaVUE-VM automatically creates a port group called, GigaPG_<vswitch name> in order to monitor traffic. |
| • | The port group is configured as Promiscuous mode with VLAN 4095. |
| • | The port group is automatically deleted when deleting the vMap. |
