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