[c-nsp] Nexus 9300 sflow performance

[Nick Cutting]

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.

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?
