yes, that's correct.  The sflow sampling rate is specified in each sflow
packet, so there is no need to specify it on the collector - it's
automatically detected on a per-packet basis.

This is a working config on a small site (albeit a different sflow agent
platform, but that won't make any difference):

nfsen will then start up sfcapd instead of nfcapd.
