Re: Switch designed for mirroring tap ports

[David Swafford <david () davidswafford com>]

Take a look at VACLs on the Cat side.  It has a capture feature that is
effectively the same as a local SPAN, but without the 2 session limit. If
you do a lot of RSPAN though, this wouldn't be your complete answer (VACL
captures are local only).  VACLs are a bit more granular in defining what's
captured, if say for example you only wanted traffic destined to TCP/80,
you could configure it that way.
