If I have the below settings:
Site model: regional hub / data center
Number of WAE: 4 (e.g. 7541)
WCCP server: Catalyst 6500 / 7600
WCCP redirect ACL entries: range from 4000 to 5000
To follow the Best Practice for WCCP integration with Catalyst 6500, I would set the WCCP source IP mask to "0x3", so that the ACL TCAM can retain within 32K entries.
However, does it mean that by setting a smaller mask value, there will be less chance for a repetitive flow to "hit" the same cache on the same WAE? Consequently would the optimization benefit be affected?
If WCCP services (61,62) are properly configured on the WCCP router/SW, having a less amount of buckets wont affect optimization.
If there is no asymmetrical effect by changing the default mask to a lower value.
