CPU utlization of a single voip cirtcuit
Our company is planning to implement VoIP on top of existing cisco network and I'm conducting network audit. Can somebody advise me the resource consumption in term of CPU utilization / Buffer utilization across all platforms (26XX ... 75xx) for a single voip circuit ? My logic if my current 4700 spends 40% CPU utilization on pure data and each voice circuits (50 pps) consumes 2%, I should not put more than 10 circuits to keep cpu in the safe zone of 60%. Similar logics for buffer. The assumption of voice circuit is: VoIP, G.729r8, no VAD. If you have conducted such kind of network audit for voip implementation before, appreciate if you can share with me privately. Thanks.

On-demand pppoe on 1750
Hi, I've sucessfully setup pppoe on 1750 for the ADSL line. However it's "always on" nature costs a lot of tariff. How can I change it this pppoe into on-demand so that only when there is packet, ppp session will be brought up. IOS is 12.1 I find nothing related in "vpdn-group" and "int dialer". Even I set the "dialer idle-timeout = 20", the session never drops. Yuenme _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Transparent Briding over Frame Relay Hub and Spoke
Hi all, I tend to conclude the following statement and pls confirm whether I'm right: "point to point" subinterface is the only option in the HUB to allow spoke to spoke packet forwarding happen in transparent bridging environment. I've tried physical interface and multipoint subinterface on hub. I've tried: - making the hub as the root bridge - extensive map statements in the hub and spoke with "broadcast" keyword All of them fail. I believe transparent bridge does not allow the packet received on one interface to be forwarded to the same interface again, even though the paths (DLCI) are different.

RE: Transparent Briding over Frame Relay Hub and Spoke
I would say not as trival as it looks. As I emphasized before, spoke to spoke connectivity is the goal. While neither physical interface, nor multipoint interface in the HUB will make spoke to spoke happen. No matter how many "frame-relay map bridge ??? broadcast" is put in. It's neither a spanning tree issue. All ports in all bridges are in forwarding state. Appreciate if anyone can show me a working config (again spoke to spoke) with hub config other than point to point subinterface Yuenme >From: "Ryan Moffett" <[EMAIL PROTECTED]> >Reply-To: "Ryan Moffett" <[EMAIL PROTECTED]> >To: "Yuen Me" <[EMAIL PROTECTED]>, <[EMAIL PROTECTED]> >Subject: RE: Transparent Briding over Frame Relay Hub and Spoke >Date: Sun, 28 May 2000 19:54:24 -0400 > >You can configure transparent bridging over Frame Relay point-multipoint >interfaces. > >See: >http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/wan_c >/wcfrelay.htm#xtocid2427346 > >Basically, on the point-multipoint subinterface, you need to associate the >DLCI's with a bridge group using the "frame-relay map bridge" command.
