Hi Tim,
Order matters. Once a match is made, the policy map is no longer parsed.
With your commands below, an SMTP packet of length 1300 would match the
first class-map. If you wanted to exclude SMTP, you could always use the
following:
class-map match-all BIG
match not protocol smtp
match packet length min 1251
That would exclude SMTP from your definition, and ensure that large SMTP
packets don't jump the queue.
Regards,
Alex

Subject: Policy-map order
Does the order under a policy-map make a difference? For example, I've
got two
class-maps, one match smtp traffic and one match packets that are over
1250 in size.
Under the policy-map, I'm calling each class-map, but how does the
router process them?
They are not nested, so if an SMTP packet that is 1300 in size, what's
gonna happen?
class-map match-all SMTP
match protocol smtp
class-map match-all BIG
match packet length min 1251
!
policy-map qos
class BIG
police 2500000
class SMTP
bandwidth 1500
Any comments are appreciated..
