Setting Up Multiport Link Aggregation

Setting Up Multiport Link Aggregation

You can aggregate multiple Network Interfaces into a single logical bonded interface to improve throughput. Once the Barracuda Load Balancer is connected to the network, use the following steps to configure link aggregation:

1. Log into the web interface, and on the BASIC > IP Configuration page, specify a WAN IP configuration; click Save Changes.
2. On the BASIC > IP Configuration page, in the Operating Mode section, verify the operation is set to Route-Path mode.
3. On the ADVANCED > Advanced Networking page, in the Network Port Configuration section, set Enable Network Port Configuration to Yes, and click Save Changes.
4. In the Link Bonding section, click Add Interface Bond; the Link Bonding page displays.
5. Enter the bond name, select the mode, and select the ports for bonding, then click Add.

6. Complete step 6 for each link bond, and then close the page.

   There are a total of 11 ports listed in the Link Bonding page. It is recommended that you create a bond with multiples of two ports, i.e., 2, 4, 6, 8.

   • WAN - Used to configure the System IP address and default system gateway
   • PORT1 to PORT10 - Configure Services on these individual ports

   Once you create a bonded interface, it is available for selection in the Port selection list throughout the ADVANCED > Advanced Networking page, and in the Interfaces list under Add New Service configuration on the BASIC > Services page.

7. Click Edit after the bonded interface name to add or delete a Network Port from the bonded interface.

   You can create a service on a bonded interface after creating the bond. To do so, go to the BASIC > Services page, click Add New Service, and configure a new service.
