When I turn of “route-only” the cpu utilization drops to 9-10% and stays stable.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I still find these values high. We previously used an old jetcore router with the same settings and that had a stable 1% cpu-utilization. It feels some sort of traffic is causing load on the cpu but so far I’ve not been able to track down the issue. Has anyone seen similar behavior?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>IronWare : Version 5.5.0cT183 Copyright (c) 1996-2013 Brocade Communications Systems, Inc.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>#sh cpu lp<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>10:27:24 GMT+01 Mon Oct 20 2014<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>SLOT #: LP CPU UTILIZATION in %:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US> in 1 second: in 5 seconds: in 60 seconds: in 300 seconds:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US> 1: 10 9 9 9<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US> 2: 10 9 9 9<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:NL'>Kind regards,<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:NL'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:NL'>Bardo Cornelissen<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:NL'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:NL'>Caveo Internet BV<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:NL'><a href="http://www.caveo.nl/"><span lang=EN-US style='color:blue'>http://www.caveo.nl</span></a></span><span lang=EN-US style='mso-fareast-language:NL'><o:p></o:p></span></p></div></body></html>
