Sflow settings recommendations wanted

[gardned1]

I have an Alcatel network with about 70 switches so need to use sflow as opposed to netflow.
What are Scrutinizer’s best practice settings for sflow on my switches.
I have seen everything from a sampling rate of 1 to 2048 and polling intervals from 5 seconds to 30 seconds used but no actual recommendations for a Scrutinizer setup. Obviously I want accurate data but I don’t want unnecessary traffic on the network if it’s not going to make much difference.

Hello Gardned1,

If you would like to email me at adam.howarth[at]plixer.com with specific model information I can provide you with a recommendation.

Typically the parameters of sflow are configured in a way that captures the most sampling data, without incurring too much overhead on the switch.

Thank you,
Adam

Hi Adam, is there no way of listing the recommended settings somewhere on the forums? Or are they too specific and should be done on a case by case basis?

Unfortunately Flow Configurations vary wildly by model and vendor, the closest thing to a recommended settings we have is our Flow configuration library
