WCCP load balancing

[Joe Lau]

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?

Thanks!

Hi Joe,

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.

Hi Adriana,

What's properly configured stand for? Does it mean setting the WCCP services (61 & 62) redirect in to the correct WAN/LAN interfaces?

Hi Joe,

That is correct.
