This is for Catalyst OS.
Jose mentions "Native IOS", which I take to mean the Athena (production) or
Cosmos (development) code trains; i.e., Catalyst 6000 series running ONLY
IOS. One IOS runs on the supervisor, one on the MSFC. the CLI is provided
by the MSFC, and talks to the supervisor via an in-band communication method
(and the slavelog is used to pass console messages from the supervisor to
the MSFC->CLI console).
This software is neat - you can set up any switchport as a layer 3 router
interface, and it beahves just like you'd expect (except that the port is
still MDI-X, not MDI). It combines the best features of the MLS
(routing-switch) way of doing things with the 8500 series (switching-router)
way of doing things. You do lose some of the super advanced features of the
Catos/MSFC hybrid (IOS VLAN ACLs, etc, but you can still do IOS ACLs
including MAC addr ACLs and most of the work is kept in hardware).
Jose, the command reference for Native IOS on 6000 begins here:
(this is for 12.1(5a)E2 and earlier releases after 12.0(7)XE).
The document you want is the SPAN configuration reference;
