Impulse is strictly out of band, Net Flow or its equivalent must be turned on. What I read and what I saw, I liked and recommended Impulse over upgrading to the new CCA hardware. Management wanted to do in-band for our Residence Halls for the sole purpose of limiting bandwidth, so that knocked Impulse out of the running.
Don't ask me how the deployment of the new hardware is going! Being a Christian I can't use those superlatives on the net! My salvation is already at risk for having such thoughts! :) In His Service, Howard From: Cisco Clean Access Users and Administrators [mailto:[email protected]] On Behalf Of Chris T. Healey Sent: Friday, January 29, 2010 3:17 PM To: [email protected] Subject: CCA 4.7.1 Bandwidth of Roles Has anyone with CCA 4.7.1 noticed that the specified Bandwidth speed of a role has been reduced to 25% of its stated value? I had a role defined for a laptop carts and using speedtest.net it was dead on a download of 1024k with a burst of 6x and an upload of 512k (non-shared). Over Christmas break I did the upgrade to 4.7.1. This term the faculty have all been trying to use the laptop carts and having all sorts of speed complaints. It was not until my PC admin lined 4 laptops up and went to speedtest and fired it up just a couple of hours ago. The speed sucked!!! Around 200k. I used my laptop in an unlimited role and got what is usually expected as our available bandwidth to the internet - a little over 10Mb. I set this role to unlimited and each laptop, one by one, got about 10Mb as well. Together they were around 8mb each (I know that 4 x 8 does not equal 10 we have packet shaping at the edge :) ). Setting the role to 4096K and they all can get about 1024, set it to 2048 and they all get about 512k. So it is not the radio(s) or the laptops - the only thing that changes is the speed listed for that role. Another old role, and I mean old by almost 2 years, is our iPhone role and its speed was also ΒΌ of what it is specified using the iPhone speedtest.net app - so I had to boost it by 4x. Anyone have any ideas as to if there is something I missed or do I need to call TAC and convince them that they seem to have a problem with 4.7.1? Also has anyone heard or experienced Impulse as a CCA replacement? Thoughts & comments welcomed, as we are starting to look for the CCA replacement.
