image.png

 

 I am trying to monitor my network using Netflow Analyzer I configured Sflow to direct to my End device i can see inflow and I don't see any out traffic, out  utilization in Netflow analyzer 

 

This is my Config For sflow , im listning on port 9996.

 

Telnet to switch 192.168.99.10

Username: admin

Password: Admin@123

Switch> enable

Pass: admin@123

(Netgear Switch) (Config)# sflow receiver 1 ip 192.168.99.10 (this is my ip)

(Netgear Switch) (Config)# sflow receiver 1 owner NetMonitor timeout 31536000

(Netgear Switch) (Config)# interface 0/1-0/26
(Netgear Switch) (Interface 1/0/1) # sflow sampler 1
(Netgear Switch) (Interface 1/0/1)# sflow sampler rate 1024
(Netgear Switch) (Interface 1/0/1)# sflow sampler maxheadersize 64

 

this is traffic utilization my interfaces as you can see there is no speed out / utilization out

and in Wireshark, I observed that all flow packets have same output interface index which is 0

all out traffic is aggregating and going through ifindex0.

has anyone faced the same issue, does anyone have a solution ???

I tried updating firmware no luck after that as well

Hi @dynamicswitcher,

 

Welcome to community!

 

It's work as design.

The 'Input Interface(ifIndex)' value will mapping to your switch interface that forwarding the packet. So could you please check if the ifIndex value is correct? In your wireshard packet, the 'Input Interface' value is 26.

 

Hope it helps!
