To Do This Notes

Ensure your basic network configuration is complete for each appliance in the CERN hierarchy
  1. See Configuring the Excelerator Appliance.

Enable the appliance to request and receive data through the hierarchy
  1. In the browser-based tool, click Hierarchy > ICP/CERN Configuration.
  2. Check Enable ICP/CERN Client.
  3. Click Apply.

See A in Figure 42.

For more information, see ICP/CERN Configuration Tab.

Designate one or more CERN parents for the appliance
  1. In the ICP/CERN Configuration tab, click CERN Parent.
  2. In the Hostname field, enter the numeric IP address or DNS name of the proxy server that you want to serve as a parent for the appliance.
  3. In the HTTP Proxy Port field, enter the port number that the parent will receive and transmit data on.
  4. In the Priority field, enter a priority for the parent.
  5. Click Apply.

See A in Figure 42.

If the appliance has multiple CERN parents, one parent must have a priority number lower than the others. (This parent will be accessed first.)

For more information, see CERN Parent Dialog Box.

Ensure each CERN parent is configured as a forward proxy server
  1. See Forward Proxy Setup.

See B in Figure 42.

A CERN parent is a proxy server that is enabled for forward proxy services.

See Client Accelerator Tab.
