Heyho, Ran into some issues around this not too long ago.
I spoke to my local SE at the time about it, and his line Was basically - what the marketing bumff says - stands!!! i.e. in my case, a Cisco 2951 was rated for 75Mbps If you turn on all the services - this may be the case - but who does that??? (recently listened to a podcast where Cisco where saying that there are over 4000 separate services in IOS) I gave him my requirements of Ethernet-Ethernet connectivity with some static routing and with some HQOS (shaping) The stats he gave me back from their internal testing was much higher that 75 Mbps. Cisco, being the engineering company they are, need to divulge much better Information and more real world stats than marketing figures to help Out us lowly engineers in the field when making decisions on kit. I found some information for you to make some informed decisions. Try this URL for some Math on ISR G1 https://supportforums.cisco.com/message/714842#714842 And this for Cisco Internal figures on ISR G2s "Ask your Cisco partner to give you access to the following document: http://www.cisco.com/en/US/partner/prod/collateral/routers/ps10536/white _paper_c11_595485.pdf Since that is proprietary information, I'm not allowed to post it here." -----Original Message----- From: cisco-nsp-boun...@puck.nether.net [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Keegan Holley Sent: 27 September 2010 06:07 To: Cisco NSPs Subject: [c-nsp] ISR G2 performance Do these numbers seem a little off to anyone else? I'm shopping again and I'm trying to compare the ISR G2's with the mainstay 3845 for a DS3 site. As usual it has been hard to find performance numbers on cisco.com. Soon I'm expecting routers that walk into the DC and install themselves only to perform at 3Mbps, but I digress... A little googling brought me the following link, but the numbers seem a little suspect. For example the entire 2800 series is rated above 45M in the document, but the product Q&A recommends the 2851 just to aggregate 6 T1's. The pages for the modules are no less misleading. Is there a way to find performance metrics for these routers stated in plain terms? http://www.cisco.com/web/partners/downloads/765/tools/quickreference/rou terperformance.pdf http://www.cisco.com/en/US/prod/collateral/routers/ps5854/prod_qas0900ae cd80169bd6.html _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
