Thanks for all replies, and sorry, guys - did not reply all, after Justin's
initial response. Here is where I am now a little confused: if this is an
ISP rate limiting config, do I really need to do anything with the

dsu bandwidth <...>

statement at my end? Shouldn't that be always the entire DS3 (44210), with
the provider "shaping" it accordingly, behind our CE-PE connection (this
goes into an MPLS cloud)? Or is the expectation that both the provider and
I are to set the dsu bandwidth to the same value, to make this possible? I
am asking this because what is happening here is an "upgrade" of bandwidth,
still under the DS3 full capacity, but with the provider controlling
(allegedly) the limit. The legacy (existing) config works (dsu bandwidth
<less than 44210>), but I am not sure that it how the ISP driven rate limit
should work.
