Hi Tim,
If you check your policy map it process your BIG class. All packet greater that
1251 is a matching criterion then your police action will be applied. So here
you are allowing SMTP as well with packets size greater that 1251.
If a packet was sent lower than 1251 size. Of course this is not a matching
criterion for class BIG then it will check the SMTP class. Then it checks your
SMTP class. If it is SMTP then your action will be applied (which is reserving
BW). If it is not then I think it will go to the default class.
I could be wrong and please correct me.
Angelo
