Load Balancing

Load balancing application performs stateless distribution of the packets between different endpoints. Stateless load balancing distributes the processed traffic to multiple tool ports or tunnel endpoints based on hash values generated from predefined protocol fields in the packet.

To add a load balancing application:

  1. Drag and drop Load Balancing from APPLICATIONS to the graphical workspace.
  2. Click the load balancing application and select Details. The Application quick view appears.

  3. In the Application quick view, enter the information as follows:
     

    Metric

    Description

    Alias

    		Enter a name for the load balancing application
    Hash Field
    • ipOnly : The source IP and destination IP addresses.
    • ipAndPort: The source IP and destination IP addresses, and Layer 4 source port and destination port numbers.
    • fiveTuple: The source IP and destination IP addresses, source port and destination port numbers, and protocol field in the IP header.
    • gtpuTeid: The GTP-u tunnel identifier (ID).

      Note:  There is no inner or outer field location for GTPU-TEID.

    Field Location
    • Outer: The first occurrence of header or field. For example, IP Only outer is the first IP header in the packet, which could be IPv4 or IPv6.
    • Inner: The second occurrence of header or field.
    The supported IP encapsulation types are: IP-in-IP, VXLAN, GTP, GRE, and ERSPAN.
    Load balancing groups

    Add or remove an application with the Endpoint ID and Weight value (1-100). A load balancing group can have minimum of two endpoints.

  4. Click Save.

Note:  When you configure the Load Balancing Application in enhanced mode, you can associate it with only a single enhanced load balancing profile. However, you have the flexibility of changing the association to different profile as needed.
