Configuring the DNCA Interface with Transparent Load Balancing

About this task

You can configure the network interface of your Network Capture Application with transparent load balancing. For more information on the benefits of enabling transparent load balancing, see DNCA Transparent Load Balancing Overview.

To configure the DNCA interface with transparent load balancing:

Procedure

  1. Open the DNCA web console.
    See Configuration via Web Console.
  2. Click the Interface tab.
  3. Select Enable Transparent Load Balancing.
  4. Enter the number of Reassd instances that you want to run.
    Increasing the Reassd instances increases the number of DNCA instances that can process TCP packets.
    Note: You can enable up to N-1 packets where N is the total number of processor cores on your server. For example, if you have a total of 8 processor cores on your server, you can run up to 7 instances.
  5. If you want to flush the SSL session information from memcache when the DNCA service restarts, select Restart Memcached server on Capture restart.
  6. If you want to disable TCP packet checksum, select Disable Packet checksum validation.
    Note: If your network interface card has packet checksum enabled, then it is recommended to disable the packet checksum.
  7. Multi-instance Capture should not be selected unless you want to return to a non-transparent load balancing mode.
  8. If you want to enter a filter rule, locate Filter Rules and enter the information for your filter; then, click Create Filter.
  9. Click Save Changes to save your changes to the DNCA configuration.
    If you want to cancel your changes, click Revert Changes.
