Sup32 is PFC3B so same as Sup720/PFC3B. PFC3B supports 128K NetFlow
entries. For us it was OK for ~2Gbps traffic with smalls customers
traffic from BRAS (a lot of flows). If you have Sup720/PFC3B then do
the POC.

Not really. It's true for 7200 and NSE-1. But not true for 7304 and
NSE-100 and NSE-150. We're still using around 7 of 7304/NSE-100 and
NSE-150 based as access-routers at happy with them.
