yes, this would make a difference. For reference, if your switch config 
is automated with L2 ACLs, then we recommend using configured macs for 
sflow collection.  If you have any rejected flows then, that means 
there's a straightforward misconfig, either in IXP Manager or else on 
the participant port.
