Webcache to wait for a response. The default is 5 seconds.

6 Select the relationship the other cache has to your Webcache from the
Type drop-down box. Choose Parent if the other cache is above your
Webcache in the caching hierarchy, Sibling/Child if it is an equal peer or
below your Webcache in the ICP hierarchy.
7 Enter the TCP port on which the other cache listens for ICP traffic in the
ICP Port box.
8 Click Add to add the cache to your Webcache’s hierarchy.
