That is the limit of what you can do.  If anything else is available I am
not sure what it would be.  You would need to back up the more important
queuing to a router interface.  Possibly even using a bridged interface on
router if you are really set about it.  At this point not sure of what else
to say.

Actually this doesn't work. Shape is the 1/x stat. 

Config guide:

In shaped mode, the egress queues are guaranteed a percentage of the
bandwidth, and they are rate-limited to that amount. Shaped traffic does not
use more than the allocated bandwidth even if the link is idle. Shaping
provides a more even flow of traffic over time and reduces the peaks and
valleys of bursty traffic. With shaping, the absolute value of each weight
is used to compute the bandwidth available for the queues. 


So, If I don't have any marking or trusting going on , would I just then
assign everything to one queue? Does that get me anything more than just
doing the 

mls srr-queue bandwidth limit 30


command as far as what the traffic is gonna look like?

Ok, thats part of what I was wondering, so I can shape bandwidth in each of
the 4 ques at 1/1 of bandwidth?

The next question is, does this have the effect of me smoothing my traffic
outbound such that I will not suffer as much (like say in TCP applications)
due to a provider policing policy?

You can do 

mls srr-queue bandwidth limit 30

mls srr-queue bandwidth shape 1 1 1 1

 

That will shape the bandwidth for all 4 output queues equally and limit
bandwidth to 30 percent of the FE interface.

Right, still not what I am talking about. If I had a router plugged into my
provider switch, I could use a shape command in a policy map on the
interface connected to the policed provider switch to shape my taffic to the
rate I've purchased. Is there anything I can do on a 3560 to get a similar
effect?

I have never had to create QoS with one bit bucket. Why bother?  The only
time QoS kicks in is when there is congestion and if you don't care what
traffic makes it through then QoS isn't going to do anything with one
bucket.  I don't know if you can even make QoS with one bucket...

I don't want the traffic soplit up into classes, I just want it to be shaped
if possible at the 30Mbps the carrier is policing me at.

There are a lot of different options when it comes to QoS so you need to
find out  what version/versions you can use on your NW.  ie DCSP, CBWFQ etc.
4 bit buckets is a good general rule of thumb to use.  You can go up to six
but looking at what you have here I don't see a need for that.

Lets say you have a customer switch (a 3560) with a Metro Ethernet Link on
one of its ports. The provider polices you to 30 Mbps. I want to shape the
traffic on my side to avoid the choppiness. 

Scenario 1: I don't have any concept of classes of traffic in my network, I
just want to try so shape to 30Mbps overall. How would you configure this?
