I can confirm that they are definitely not lying about ‘degraded performance’ when you get your shaper config “wrong”.
That being said, I’m not sure what actual impact it will have on such a low-bandwidth circuit either. - Jacob Bisby From: AusNOG <ausnog-boun...@lists.ausnog.net> On Behalf Of David Fowler Sent: Thursday, 24 May 2018 3:33 PM To: Brad Henshaw <hen...@gmail.com> Cc: ausnog@lists.ausnog.net Subject: Re: [AusNOG] ASR 903 Shaping Hi Brad I think we do. Telstra pretty explicit saying this is required else “you’ll experience degraded performance”. Their 4Mb EA spec wants a 32000 bit BC when the shaper can only be configured with a minimum 60000.

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.

Seems with this platform the lowest is 60000 bits… this doesn’t help when we need to configure 4Mbps Telstra EA policies… Maybe a different software version?
