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.
