sFlow and 2848 switch

[Greg Krzeszkowski]

Hi,

I've been searching forums, google etc for some idea of what I need to do to enable sFlow on 2848 switches. I'm using a product called Scrutinizer that analyses sFlow/netFlow data and would like it to analyse my switches. An help would be appreciated.

whatever you use HP PCM+ or other sflow collector software you can see the flow about source and destination ip address pairs.

for my personal, i use the SflowTrend to collect the sflow sample.
you can download the software from below website, it's free.

Hi Greg,

This looks like an interesting product with some potential.

Currently it looks as though you need to enable sFlow manually to use it with this product.

Other applications such as PCM+ and InMon Traffic Sentinal do this for you automatically.

With the new 5400/3500's you can configure sFlow via the CLI - with everything else you need to do this via SNMP.

When using SNMP, InMon have a bash script that you can use to help simplify this - sflowenable - http://www.inmon.com/technology/sflowenable

I also came across this which may be of some interest to you:

I have been using the sflowenable script and ntop on HP5308XLs

For some strange reason ntop did not show the correct information with sflow. I am using sflowtool to convert the sflow from the switch to netflow.
