Introduction

A VLAN (virtual LAN) is a logical interface that is configured on top of a physical interface, providing an additional virtual layer, thus allowing to support more services. Services (NAS, iSCSI, replication) can either use VLANs or other, non-VLAN interfaces. The data they send is VLAN-tagged - or not tagged - accordingly.

Limits

• Maximum 200 VLANs per node
  Since nodes are configured symmetrically, this also means 200 VLANs per system. 

Limitations

• VLANs are only supported on LACP interfaces that were created using InfiniBox 3.0 or later
  • VLANs are not supported on LACP interfaces that were created on InfiniBox versions prior to 3.0
  • VLANs are not supported on ports.
  • To enable VLANs on pre-3.0 interfaces, contact support.
• As VLANs inherit their state from the underlying LACP interface, they cannot be disabled
• The name of the VLANs must be identical across all nodes.

Viewing the VLANs on the GUI

To access the VLANs view:

1. Click Settings from the GUI menu and then click the Network Interfaces tab. Click one of the Network Interface. The Network Interface screen opens.
2. The Network Interface screen displays the way the Network Interface uses VLANs for the various InfiniBox services.
    

Configuring VLANs on the GUI

Step 1 - Configure VLANs on the Port Group

Before you begin

• Make sure that there is a Port Group defined for the VLAN

To configure a VLAN:

1. On the GUI, click the Settings icon on the toolbar on the left, and then click the Network Spaces tab. 
2. Click Create on the upper right of the page.
3. In the Create Network Space popup window, select Create VLAN at the bottom of the window.
4. Enter the VLAN tag ID. The possible range is 1-4096.
5. If needed, you can select the nodes to associate with the VLAN. The node identifier will be Node_id.VLANTagID.
   
   
6. Click Create.
   The VLANs are created on the Port Group.

Step 2 - Configure the network spaces for the VLAN

1. On the GUI, click the Settings icon on the toolbar on the left, and then click the Network Spaces tab. 
2. Click Create on the upper right of the page.
3. In the Create Network Space popup window, enter a Network Space Name.
4. From the Service field, selelct NAS.
5. In each of the 3 nodes, select the Port Group that is associated with the VLAN.
   
   
6. Click Next.
7. Enter a valid network ID, and any other network configurations, if needed.
   The Network Map is displayed.
   

Configuring VLANs using InfiniShell

To configure VLANs using InfiniShell

1. In the GUI, select the 3 bars with the exclamation mark on the upper right of the interface .
2. From the command line, enter the following...
   

   config.ethernet.interface.create_vlan physical_interface=pg_data1 vlan_id=3649

3. Hitting the TAB key will display the list of possible options for each command. At least one option must be selected per option. Options in brackets are optional. 

Deleting VLANs

Step 1 - Delete the network space

1. On the GUI, click the Settings icon on the toolbar on the left, and then click the Network Spaces tab. 
2. Right-click the network space to delete, and select Delete Network Space.
   The network space is deleted.

Step 2 - Delete the VLANs

1. On the GUI, click the Settings icon on the toolbar on the left, and then click the Network Interfaces tab. 
2. Click on the Port Group where the VLANs are contained.
   The VLANs will be displayed on the Network Map.
3. Select the VLAN tab.
4. Right-click on the VLAN and select Delete VLAN. 
   If there are more than one VLAN, select them all using the checkboxes, right-click and select Delete Entities.
