Environment

Dell switches

Problem

If you've configured Dell devices by their guidelines( https://www.dell.com/support/kbdoc/en-us/000116368/how-to-configure-sflow-on-dell-emc-networking-n-series-switches ) and you still don't see the traffic.

Cause

Setting the forward traffic to default collector(Netflow instead of Sflow) in this example:

sflow enable

sflow sample-rate 4096

sflow source-interface vlan700

sflow collector 172.16.23.233 agent-addr 172.16.23.232 2055

Solution

  1. If you are using sflow, check that you are sending to sFlow port(by default 6343) and not Netflow, because they are different protocols.
