Dell OS10- Sflow setup

These commands should be all that is needed to setup Sflow on OS10. In this example these commands used to setup Sflow on a Dell S4128F-ON running 10.4.2.0.226. I am using PRTG as a collector.

config t
sflow enable
sflow sample-rate 4096
sflow source-interface vlan5
sflow collector 10.10.5.152 agent-addr 10.10.5.246 2050

PRTG IP is 10.10.5.152 – my switch Vlan 5 IP is 10.10.5.246.

Then you have to specify the physical interfaces you want to send Sflow traffic.

config t
int eth 1/1/1
sflow enable

That should get flows going. You can confirm that by running the following command:

S4128-1# show sflow
sFlow services are enabled
Management Interface sFlow services are disabled
Global default sampling rate: 4096
Global default counter polling interval: 30
Global default extended maximum header size: 128 bytes
Global extended information enabled: none
1 collector(s) configured
Collector IP addr:10.10.5.152 Agent IP addr:10.10.5.246 UDP port:2050 VRF:Defaul t
7232 UDP packets exported
0 UDP packets dropped
39259 sFlow samples collected
