It's got datagrams sent set at 0. Have you enabled sampling on any interfaces?

What does "show sflow sampling" say?

OK, looks like you don't have any interfaces with sampling enabled: there is a sample script that should do this for you.

I believe netflow also include something similar with their product.

Hi,

Thanks for the script. Is there a way I can configure this on the switch ?

Let me know

"Thanks for the script. Is there a way I can configure this on the switch ?"

You can use setmib from the command line to issue the SNMP sets that the script would.

Unfortunately, there isn't much friendly command line support for sflow - HP expects your network monitoring tool to do it for itself, I think.
