In particular I found that configuring the same mask value set on every cache to be somewhat counter intuitive.
Using 5 caches I was not able to configure more than 3 mask values per cache without caches dropping out of the service group. Using only 2 caches I was able to configure 18 mask values per cache. I suspected an mtu issue due to the large datagrams used by WCCP. I followed the guidlines in 'Choosing the optimum WCCP request distribution method' to configure mask assignment. The link is unfortunately only available to registered customers. Interestingly the same document states that the limitation of 64 mask values is due to the maximum datagram size that can be processed on the Netcache being 4000 bytes. Testing with Squid (2 caches) and mask assignment I was able to get 32 mask values per cache. The weight attribute did not appear to have any effect on distribution of the mask values as it does with hash assignment. I would like to use mask assignment for obvious reasons but having only 3 mask values per cache is not feasible. Thanks for the info on this it is greatly appreciated. > Yes it is, and even more so when combined with spoofing on the cache, > since outbound would become quite a nightmare, causing many potential > redirect loops > > Also the later SXF versions of IOS fixed many WCCP issues present in > older versions > _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
