In-Reply-To: <A925AC5C659BD64FBA4E84EC349688730B433CC8@CEXMB4.nmes.lcl> Date: Thu, 8 Jul 2010 16:35:24 -0700 From: Kenny Sallee <kenny.sallee@gmail.com> To: "Murphy, Jay, DOH" <Jay.Murphy@state.nm.us> Cc: nanog@nanog.org Errors-To: nanog-bounces+nanog.discuss=bloom-picayune.mit.edu@nanog.org I think if you try to traffic-shape 80Mbps on that platform you'll have problems. We have a 7200 with NPE-G1 (rate limited at 80Mbps) and it kille= d the CPU when the threshold was hit. I imagine that traffic-shaping would d= o the same to CPU and memory. I'd lab it first.
