Symptom
For the N7k platforms there is no verified scalibility number available to confirm. It needs to be more clear to customers what the scalability limits on WCCP programming are supported.
To accomplish this, we should document a Verified Scalability Guide for WCCP which details a number of potential profiles that we can reliably supported.
Conditions
In certain scenario where customer migrate from Cat6k to N7k, they end up in consume all the resource due to large number of policies.
One sceanio
Number of interfaces 60
WCCP service group 8
Each wccp service group have 8 or more ports attached.
5 ACLs each over 200 lines
MASK value 7F
In above scenario box was not even able to modify the polices in 5 Minutes and SPM timeout.
Only lower mask to 0xF didn't help.
Workaround
Lower the number of interfaces wccp applied.
Lower the mask value
Reduce the number of port attached to each service group
Reduce the number of lines in ACL.
