Re: RSPAN in 3550 with reflector port

What part makes no sense? You need to associate ASICs with the process
in order to have and semblance of sanity and performance in your mirroring!

3550's, the ASICs belong to ports, so you need to borrow one. Or
appropriate them. That leaves the underlying port unable to be used.
3560's, the ASICs belong to the chassis and are allocated as necessary,
therefore it's not needed to do any specific allocation.
