Identifying which WAE in a farm recieves a flow when using mask assignment

[ckistner]

Hi,

I wonder if someone can help me.  I need to work out which of the WAEs in my farm will receive a particular flow.  I can do this for the locations where I am using hash assignment, but how do I get this information for a location where I am using mask assignment?

Thanks

Here's a form you can use fo calculate to which bucket a particular IP would be assigned:

WCCP Mask (HEX)		HEX	First Octet								Second Octet								Third Octet								Fourth Octet								Number of Buckets
0x7F		0x0000007F	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	1	1	1	1	1	1	1	128
IP to Calculate (Opt.)																																			IP assigned to Bucket
192.168.0.11		0xC0A8000B	1	1	0	0	0	0	0	0	1	0	1	0	1	0	0	0	0	0	0	0	0	0	0	0	0	0	0	0	1	0	1	1	11

Enter your WCCP Mask choice and map out the binary mask value and enter an IP  address to be evaluated against the mask. Anding the values yields the bucket assignment. Since WAE WCCP  Bucket assignment varies, you will need to compare this to the  output of "show ip wccp [61 or 62] detail" on your router/switch, or  "show wccp mask tcp-pro" on your WAE to determine the bucket to WAE  mapping.

Your Cisco Account team can provide you with an excel spreadsheet that will perform these calculations automatically.
