What about software switched traffic (mostly glean traffic)? Doesn't that get handled by the RP?
Yes. But such traffic must come in via a gigE or vlan interface, and ERSPAN can capture it there (in hardware)
You can *also* span the RP/SP itself, and as I understand it again this is done in hardware. Effectively it SPANs the internal gigE port facing the RP/SP
We've used ERSPAN on some truly phenomenal bitrates; it *is* done in hardware.
