That’s a very underpowered processor for that job. The ESP40 was designed for a box that would have 1G interfaces and perhaps a couple of 10’s. The ASR1000 is a CPU based box, everything goes back to the processor and remember cisco math means half duplex not full.<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US>From:</span></b><span lang=EN-US> NANOG <nanog-bounces+tony=wicks.co.nz@nanog.org> <b>On Behalf Of </b>Colin Legendre<br><b>Sent:</b> Saturday, 27 November 2021 8:09 am<br><b>To:</b> nanog <nanog@nanog.org><br><b>Subject:</b> Latency/Packet Loss on ASR1006<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Hi,<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>We have ...<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>ASR1006 that has following cards...<o:p></o:p></p></div><div><p class=MsoNormal>1 x ESP40<o:p></o:p></p></div><div><p class=MsoNormal>1 x SIP40<o:p></o:p></p></div><div><p class=MsoNormal>4 x SPA-1x10GE-L-V2<o:p></o:p></p></div><div><p class=MsoNormal>1 x 6TGE<o:p></o:p></p></div><div><p class=MsoNormal>1 x RP2<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>We've been having latency and packet loss during peak periods...<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>We notice all is good until we reach 50% utilization on output of...<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal>'show platform hardware qfp active datapath utilization summary'<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Literally ... 47% good... 48% good... 49% latency to next hop goes from 1ms to 15-20ms... 50% we see 1-2% packet-loss and 30-40ms latency... 53% we see 60-70ms latency and 8-10% packet loss.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Is this expected... the ESP40 can only really push 20G and then starts to have performance issues?<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p><div><div><div><div><div><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>---<br>Colin Legendre<o:p></o:p></p></div></div></div></div></div></div></div></div></body></html>
