We have one G1 that was just implemented with 15T1. We also have 2 running 11T and 1 running 9T. The 2 running 11T have, IMO, very high CPU (60+% average durning middle of day). The 9T barely runs 20%.
I am planning on upgrading one of the 11Ts to see if the CPU issue was resolved. I will post up when I get some data. tv ----- Original Message ----- From: "Rodney Dunn" <[EMAIL PROTECTED]> To: "Rafi Sadowsky" <[EMAIL PROTECTED]> Cc: <[email protected]>; "Hank Nussbacher" <[EMAIL PROTECTED]> Sent: Monday, July 30, 2007 8:15 AM Subject: Re: [c-nsp] 12.4(11)T QoS problems (again) > On Sat, Jul 28, 2007 at 07:18:24AM +0300, Rafi Sadowsky wrote: >> Hi Rodney, >> >> FYI: The router is a 7206VXR NPE-G1 with most of traffic between 2 of >> the >> NPE GbE interfaces > > Ok.
