directions simultaneously. Firewalling is just simple ACLs obviously, and you have to plan them carefully to make sure they get processed in ASIC and not CPU.<o:p></o:p></span></p>

the end of their useful routing life, they can be repurposed into non-critical places as access switches.<o:p></o:p></span></p>

<p class="MsoNormal">Yes, but...... now your also buying Smartnet on two devices. But I do get your point. Difficult piece is does your layer 3 switch support QoS. Policing, shaping, etc?<o:p></o:p></p>

that's a very good point Mike. most of the time the licenses are not transferable. sometimes modules are though, sometimes. ;)<o:p></o:p></span></p>
