<div dir="ltr">Hi,<br><br>I'm working through troubleshooting a 200M EA service. Shapers are done on Juniper MX (head end) and Juniper SRX300 (customer end).<br><div>
</div><div><br></div><div>Ingress we are receiving full bandwidth to shaping value (195Mbps)</div><div>Egress we are only receiving 30Mbps for TCP traffic only.</div><div><br></div><div>If I clamp the shaper down to 10Mbps, I see that the speed drops to a flat 9.8Mbps.</div><div><br></div><div>If I do an iperf using UDP, I'm seeing the full 195Mbps from client machine out.</div><div><br></div><div>Does anyone have any ideas about what this could be? We've got a few other SRX300s in the field using the same config; and so it doesn't look like that's the problem - and also given that clamping the shaping to 10Mbps evens the results it seems like the SRX won't be what is at fault.</div><div><br></div><div>Shaper config on customer side:</div><div><br></div><div><div><font face="monospace, monospace"># show class-of-service </font></div><div><font face="monospace, monospace">interfaces {</font></div><div><font face="monospace, monospace"> ge-0/0/0 { <!-- this is facing customer machine for testing</font></div><div><font face="monospace, monospace"> unit 0 {</font></div><div><font face="monospace, monospace"> scheduler-map policer;</font></div><div><font face="monospace, monospace"> }</font></div><div><font face="monospace, monospace"> }</font></div><div><font face="monospace, monospace"> ge-0/0/5 { </font><span style="font-family:monospace,monospace"><!-- this is facing Telstra NTU</span></div><div><font face="monospace, monospace"> unit 0 {</font></div><div><font face="monospace, monospace"> scheduler-map policer;</font></div><div><font face="monospace, monospace"> }</font></div><div><font face="monospace, monospace"> }</font></div><div><font face="monospace, monospace">}</font></div><div><font face="monospace, monospace">scheduler-maps {</font></div><div><font face="monospace, monospace"> policer {</font></div><div><font face="monospace, monospace"> forwarding-class best-effort scheduler rate-limit-195m;</font></div><div><font face="monospace, monospace"> }</font></div><div><font face="monospace, monospace">}</font></div><div><font face="monospace, monospace">schedulers {</font></div><div><font face="monospace, monospace"> rate-limit-195m {</font></div><div><font face="monospace, monospace"> shaping-rate 195m;</font></div><div><font face="monospace, monospace"> }</font></div><div><font face="monospace, monospace">}</font></div></div><div><font face="monospace, monospace"><br></font></div><div><div style="font-family:monospace,monospace"># run show class-of-service scheduler-map policer </div><div style="font-family:monospace,monospace">Scheduler map: policer, Index: 55355</div><div style="font-family:monospace,monospace"><br></div><div style="font-family:monospace,monospace"> Scheduler: rate-limit-195m, Forwarding class: best-effort, Index: 19467</div><div style="font-family:monospace,monospace"> Transmit rate: unspecified, Rate Limit: none, Buffer size: remainder, Buffer Limit: none, Priority: low</div><div style="font-family:monospace,monospace"> Excess Priority: unspecified</div><div style="font-family:monospace,monospace"> Shaping rate: 195000000 bps</div><div style="font-family:monospace,monospace"> Drop profiles:</div><div style="font-family:monospace,monospace"> Loss priority Protocol Index Name</div><div style="font-family:monospace,monospace"> Low any 1 <default-drop-profile> </div><div style="font-family:monospace,monospace"> Medium low any 1 <default-drop-profile> </div><div style="font-family:monospace,monospace"> Medium high any 1 <default-drop-profile> </div><div style="font-family:monospace,monospace"> High any 1 <default-drop-profile> </div><div style="font-family:monospace,monospace"><br></div><div style="font-family:monospace,monospace"><br></div><div><font face="arial, helvetica, sans-serif">UDP Iperf from client outbound that shows it's not the link capacity…</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div><div><pre style="padding:6px 10px;font-family:consolas,"bitstream vera sans mono",courier,monospace;font-size:12.025px;color:rgb(51,51,51);border-radius:3px;margin-top:15px;margin-bottom:15px;line-height:19px;word-break:break-all;word-wrap:break-word;white-space:pre-line;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;background-color:rgb(248,248,248);border:1px solid rgb(204,204,204);outline:0px;vertical-align:baseline;overflow:auto">[ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams<br>[ 3] 0.0-27.7 sec 636 MBytes 192 Mbits/sec 0.029 ms 24291/478152 (5.1%)<br>[ 3] 0.0-27.7 sec 1 datagrams received out-of-order<br>[ 4] local xx port 5001 connected with xx port 58752<br>[ 4] 0.0-10.3 sec 229 MBytes 187 Mbits/sec 16.141 ms 8958/172410 (5.2%)<br>[ 4] 0.0-10.3 sec 1 datagrams received out-of-order<br>[ 3] local xx port 5001 connected with xx port 60477<br>[ 3] 0.0-10.0 sec 228 MBytes 191 Mbits/sec 0.039 ms 9595/172190 (5.6%)<br>[ 3] 0.0-10.0 sec 1 datagrams received out-of-order<br>[ 4] local xx port 5001 connected with xx port 50602<br>[ 4] 0.0-30.0 sec 683 MBytes 191 Mbits/sec 0.023 ms 29513/516460 (5.7%)</pre></div><div style="font-family:monospace,monospace"><br></div><div><font face="arial, helvetica, sans-serif">Any advice/input would be appreciated.
