Adding an aggregate interface

You can configure an aggregate interface in WebSphere® DataPower® XC10 Appliance.

Before you begin

You must be assigned the WebSphere DataPower XC10 Appliance administration permission to perform these steps.

About this task

You can link multiple network interfaces into a single aggregate interface. An aggregate interface is made up of one or more Ethernet interfaces to act as a single logical unit. Use this feature to distribute traffic over your network. You can use the command-line interface or the web console to create an aggregate interface. Using the command-line interface to create aggregate interfaces is the preferred approach. For each operation, you must log in to the appliance first. After you complete an operation, run the clear-all command, and restart your appliance.

Link aggregation between switches provides increased connectivity, redundancy, and expanded bandwidth.
  • Increased bandwidth
    Multiple Ethernet Interfaces are combined into one logical link, as an aggregate interface, which increases the bandwidth that is available to the appliance.
    Remember: With the appliance, you can enable either 1 Gbps ports or 10 Gbps ports. Therefore, if you enable 10 Gbps Ethernet ports, then you can also aggregate 10 Gbps ports.
  • Automatic failover

    Traffic on a failed Ethernet port in an aggregate is transferred to a working Ethernet port. When you use a single switch, this can protect against port failures. By using redundant switches, you can protect against network switch failures.

  • Load balancing

    You can select load balancing policies to distribute both inbound and outbound traffic.

  • Support for redundancy

    Two systems can be connected by multiple links in various aggregation configurations.

  • Improved administration

    As an administrator, you can manage multiple Ethernet Interfaces as a single aggregate interface unit.
