Good point. We waited for the second Gen Regarding 60 Gbs, isn’t that is the data traffic, not the flows or sampled flows levels?
Our NFSEn box is centos 4 vCPU and 4 GBrams Collecting flows from maybe only 30 devices, about 20Gbs and 3k flows per sec. -----Original Message----- From: Tim Stevenson (tstevens) <tstev...@cisco.com> Sent: Wednesday, March 20, 2019 11:20 AM To: Nick Cutting <ncutt...@edgetg.com>; Satish Patel <satish....@gmail.com>; cisco-nsp@puck.nether.net Subject: RE: [c-nsp] Nexus 9300 sflow performance This message originated from outside your organization. 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.

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. -----Original Message----- From: cisco-nsp <cisco-nsp-boun...@puck.nether.net> On Behalf Of Satish Patel Sent: Wednesday, March 20, 2019 8:21 AM To: cisco-nsp@puck.nether.net 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?
