Make sure you distinguish between N9300 (1st generation) and N9300-EX/FX/FX2
(2nd generation). The SFLOW + SPAN limitation applies only to the latter. It's
also on the latter that Netflow is supported, which can run concurrently with
SPAN sessions.

We use sflow on 9300's, no performance hit - but you cannot use span sessions
at the same time.
Newer code revisions support netflow, without the SPAN session limitation,
although we have not tried netflow on the 9300 yet.
For a collector We use NFSEN - opensource, and quite a big install base, and it
seems to handle a lot of flows.
It supports sflow and netflow as we have a mix, just make sure you add the
sflow option at build time as it’s a bit funky old linux to add it after.

Subject: [c-nsp] Nexus 9300 sflow performance
This message originates from outside of your organisation.
Folks,
I have L3 Nexus 9300 switch which is running 60Gbps traffic on ISP interface so
I’m planning to run sflow on that specific interference to get flow.
Does it going to create any performances issue on switch?
Can I run sflow on Layer 3 LACP interface?
Can anyone suggest free open source sflow collector?
