[c-nsp] Storm Control Value tuning?

[Dan Armstrong]

For those people that have implemented storm-control on their 
customer-facing switches - what sort of values you are using?

We find that if we set broadcast & multicast to around 10% we can 
usually weather anything a customer can throw at us - I'm wondering, if 
especially the 10% on the multicast might actually cause some legit 
things to be blocked?

Any insight is most appreciated.
