Peering with SkyCache CA

To peer the Cisco Cache Engine with the SkyCache CA, you will need to edit settings in the ICP Server and ICP Client sections of the web management interface.

Within the ICP Server menu:

Set the Enable ICP Server option to 'On'
Enter the SkyCache CA hostname into the Valid ICP Clients box, and toggle the Fetch Misses switch to 'Yes'

Within the ICP Client menu:

Set the Enable ICP Client option to 'On'
Set Max wait for replies to 2 seconds
Enter the SkyCache CA hostname into the ICP Servers box
Set the Parent option to 'No'
Set the appropriate ports for the SkyCache CA in the HTTP and ICP boxes (3134 for HTTP and 3132 for ICP)

Notes

To verify that you are receiving objects properly from the SkyCache feed, look in the HTTP logs and verify that objects that are requested from the SkyCache CA are being retrieved with a retrieval method of SIBLING_HIT. If objects are being retrieved directly and not via the SkyCache CA, you will want to make sure your peering with the SkyCache CA is setup properly.

Statistics about hit rates and performance within the web management interface will be tainted by the SkyCache feed, due to the method involved in getting objects into the cache. Counters for hit rate percentages in particular will appear much lower than their actual value. To get accurate numbers for cache performance, logs will need to be pulled from the server and post-processed with connections from the SkyCache CA removed.
