Thanks, Joel!  We'll give it a spin.

Indeed.  That's why we are trying it on a 100M port. :)

29xx maps to a multitude of devices but something like the following on ios xe

1.    enable

2.    conf t

3.    policy-map bloat-policy

4.    class class-map-bloat

5.    bandwidth {bandwidth-kbps | percent percent

6.    queue-limit number-of-packets

7.    end

packets-per-queue range is 1 to 2,000,000 on an asr, that should be enough for some clowning.

5ms on 100G port is stll around half a gig so your milage may vary.
