[c-nsp] Erspan on 7600

[Mack McBride]

What about software switched traffic (mostly glean traffic)?
Doesn't that get handled by the RP?

Hi Martin,

ERSPAN is handled by the hardware, either the central replication 
engine on the sup, or by the REs on the linecards themselves (depends 
on which sup & LCs you have).

In no case do we use the sup CPU to perform ERSPAN encap/decap.
