NBAR discovery on 3850???

I'm working on a very extensive QOS project, and the first thing I would like to do is turn on nbar protocol-discovery, but it seems the 3850s don't have that command option anymore???  Is there an alternative at looking at what kind of traffic I have traversing a switch?    Thanx.

You've discovered one of the differences between a Cisco L3 switch and a Cisco router, the former is often poorer in feature supported.

The only L3 switch, that I'm aware of, that had something like NBAR was the 6500 with a sup-32 PISA, which supported FPM.

As to alternatives, some NBAR is just the same as ACL but with a "pretty face".  Some NBAR, though, does deeper packet inspection.  The latter, just cannot be done on almost all Cisco L3 switches.

If you really need advanced NBAR matching, you'll need a Cisco ISR or ASR.

Thanx for the answers guys, I

Thanx for the answers guys, I was hopping to be able to do some "smarter" markings based on protocols, rather then ACLs, and the usual IP addressing, ports, etc...
