<div dir="ltr">After reading the Medianet document, I'm certain they are just giving you an example, not a definitive answer nor the best practice. While 128kbps does police the port to a single g711ulaw call, it also allows for a little wiggle room, which I like. If you are looking for the absolute minimum bandwidth needed for a g711ulaw call, you could go lower than 128kbps, but you wouldn't gain anything. Don't forget that the BIB of the phone could cause more than a single call's worth of RTP to ingress the switch port, in which case your 128kbps would not be enough and you would have issues with things such as network recording or silent monitoring.<br></div><br><div class="gmail_quote">On Wed, Apr 15, 2015 at 9:19 AM abbas Wali <<a href="mailto:abbaseo@gmail.com">abbaseo@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)">medianet is </div><div class="gmail_default"><font color="#000000" face="tahoma, sans-serif"><a href="http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND_40/QoSCampus_40.html" target="_blank">http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND_40/QoSCampus_40.html</a></font><br></div><div class="gmail_default"><font color="#000000" face="tahoma, sans-serif"><br></font></div><div class="gmail_default"><font color="#000000" face="tahoma, sans-serif">Vik's post </font></div><div class="gmail_default"><font color="#000000" face="tahoma, sans-serif"><a href="http://www.collabcert.com/blog/qos/how-much-bandwidth-does-1-call-consume/" target="_blank">http://www.collabcert.com/blog/qos/how-much-bandwidth-does-1-call-consume/</a><br></font></div><div class="gmail_default"><font color="#000000" face="tahoma, sans-serif"><br></font></div></div><div class="gmail_extra"></div><div class="gmail_extra"><br><div class="gmail_quote">On 15 April 2015 at 13:44, Anthony Holloway <span dir="ltr"><<a href="mailto:avholloway+cisco-voip@gmail.com" target="_blank">avholloway+cisco-voip@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Can you link us to the sources in question? I personally need a little more context to go with your question. <br><br>In general, policing a single g711ulaw call is around 93kbps, and rounding it to 100kbps still achieves the goal of policing a single call. And yes, a class based policer would police media and signaling separately. <br><br>Also, I saw something on medianet at last year Cisco Live, but other than that, I'm clueless about medianet. I can't say if and how things changed once medianet came in to the picture. I'm sure Vik wasn't considering that either, based on the fact that he teaches CCIE Collab boot camps, and medianet is not a part of the blueprint. <br><div class="gmail_quote"><div><div>On Wed, Apr 15, 2015 at 4:22 AM abbas Wali <<a href="mailto:abbaseo@gmail.com" target="_blank">abbaseo@gmail.com</a>> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div><div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)">hi all,</div><div class="gmail_default" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)">Vik Malhi posted that for a successful g711 call </div><div class="gmail_default" style="font-family:tahoma,sans-serif;color:rgb(0,0,0)"><pre style="border:1px solid rgba(0,0,0,0.0980392);font-family:monospace,serif;font-size:15px;margin-top:0px;margin-bottom:24px;outline:0px;padding:12px;vertical-align:baseline;line-height:24px;max-width:100%;overflow:auto;white-space:pre-wrap;word-wrap:break-word;color:rgb(43,43,43)">HQSW(config-pmap-c)#police 90500 8000 exc drop ! 0 packet loss</pre><pre style="border:1px solid rgba(0,0,0,0.0980392);font-family:monospace,serif;font-size:15px;margin-top:0px;margin-bottom:24px;outline:0px;padding:12px;vertical-align:baseline;line-height:24px;max-width:100%;overflow:auto;white-space:pre-wrap;word-wrap:break-word;color:rgb(43,43,43)">now, as per Ciso medianet 4</pre><pre style="border:1px solid rgba(0,0,0,0.0980392);font-family:monospace,serif;font-size:15px;margin-top:0px;margin-bottom:24px;outline:0px;padding:12px;vertical-align:baseline;line-height:24px;max-width:100%;overflow:auto;white-space:pre-wrap;word-wrap:break-word;color:rgb(43,43,43)"><span style="color:rgb(0,0,0);font-family:Arial,Helvetica,sans-serif;font-size:11.3999996185303px;line-height:normal;white-space:normal">The VoIP and signaling traffic from the VVLAN can be policed to drop at 128 kbps and 32 kbps, respectively (as any excessive traffic matching this criteria would be indicative of network abuse)</span><br></pre><pre style="border:1px solid rgba(0,0,0,0.0980392);font-family:monospace,serif;font-size:15px;margin-top:0px;margin-bottom:24px;outline:0px;padding:12px;vertical-align:baseline;line-height:24px;max-width:100%;overflow:auto;white-space:pre-wrap;word-wrap:break-word;color:rgb(43,43,43)">Question is 128 kbps supports 1 single voice stream of g711 OR if you go with Vik, you need to multiply 90500 with the number of calls you need on that port.
