Creating a Link Bond on the Barracuda Load Balancer ADC Vx for Amazon Web Services

You can attach multiple interfaces to the Barracuda Load Balancer ADC Vx, and bond those interfaces to increase the throughput of the Barracuda Load Balancer ADC Vx. The maximum number of interfaces that you can attach to the Barracuda Load Balancer ADC Vx instance depends on the instance type. For more information on instance types, see Licensing Options.

Step 1. Attach Multiple Interfaces to the Barracuda Load Balancer ADC Vx Instance

1. Turn OFF the Barracuda Load Balancer ADC Vx.
2. Log into the Amazon EC2 Management Console.
3. From the EC2 dashboard, select Network Interfaces under NETWORK & SECURITY.
4. Create the additional network interfaces. For each interface:
   1. Click Create Network Interface.
   2. In the Create Network Interface window, provide the following information for the network interface:
      • Description – Enter a name for the interface.
      • Subnet – Select the subnet of the VPC where you created the Barracuda Load Balancer ADC Vx instance.
      • Private IP – It is recommended that you enter a static IP address.  
      • Security Groups – Select the security group that you created for the Barracuda Load Balancer ADC Vx instance.
   3. Click Yes, Create.
5. In the Network Interfaces table, right-click an interface that you want to bond and then click Attach.
6. In the Attach Network Interface window, select the Barracuda Load Balancer ADC Vx instance ID and click Attach.
7. Repeat steps 5 and 6 to attach the additional network interfaces to the Barracuda Load Balancer ADC Vx instance.

Step 2. Create the Link Bond

1. After you attach the network interfaces, turn ON and log into the Barracuda Load Balancer ADC Vx. 
2. On the BASIC > Status page, verify that the attached interfaces are displayed in the Interfaces section.
3. Go to the NETWORK > Ports page and create the link bond as per your requirement.

Next Step

Now, you can use this bond to create services with more throughput, as compared to services configured on a single interface. Continue with Configuring Services on the Barracuda Load Balancer ADC Vx for Amazon Web Services.
