It was a while ago but I recall when working with the ASR920 I found the burst values automatically calculated by IOS (without manually specifying Bc/Be) worked pretty effectively when using 'shape average' in multi-level policies. I haven't touched a 903 however so don't know if its behaviour is different.<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal>Regards,<o:p></o:p></p></div><div><p class=MsoNormal>Brad<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p><div><p class=MsoNormal> <o:p></o:p></p><div><p class=MsoNormal>On Thu, May 24, 2018 at 3:37 PM, David Fowler <<a href="mailto:David.Fowler@datacom.com.au" target="_blank">David.Fowler@datacom.com.au</a>> wrote:<o:p></o:p></p><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0cm 0cm 0cm 6.0pt;margin-left:4.8pt;margin-top:5.0pt;margin-right:0cm;margin-bottom:5.0pt'><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-GB>Hi folks</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-GB> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-GB>Does anyone know if it’s possible to enter in a lower BC value in a Shaping policy?
