I have to solve an issue with redundancy and i was wondering which option would require me less gear for redundancy?  would it be N+1 or 1+1 with SSO?   Would anyone have come across similar like issue? ... View more

Dear forum members, has anyone come across a Cisco Validated Design for a municipal WIFI solution?  If so I would sincerely appreciate if someone can shed some light on some research and reading I have been doing for sometime now. A high level architecture diagram, and or even a Low Level Design document would be more than appreciated. Thank you once again and have a great day ... View more

Hey there WLAN gurus, i have a question which applies only on the legacy 2.4 GHz spectrum. I have a high in interference high density wifi environment, which results to high channel utilization, i followed best practices, disabled lower data rates, did an RF survey, checked DCA, TPC, coverage hole detection, aggresive loading balancing to name a few. Long story I have been able to stabilize the network considerably, My question is should I enable optimized roaming? which I have it enabled as we speak but on the default values, anyone has some best practices to share here? from an RSSI, Data Rates, and time perspective? Essentially I have sticky clients at -66 dBm but they are crawling in the range of 2-4 Mbps Up/Down, and this is what I am trying to figure out. Also would 802.11K help me here? Please see the links I am referring too. http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-0/configuration-guide/b_cg80/b_cg80_chapter_010011001.html http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_01100111.pdf Thank you ...

Hey everyone, I have this question, does anyone know how much time it typically takes to transition on the same SSID but between 2.4 and 5.0 spectrum? Essentially i have clients that in certain areas of the floor are associated on the SSID on the 2.4 Spectrum, but when they move around they are associating themselves on the same SSID but on the 5.0 Spectrum, this transition can take up to a minute if not longer, Has anyone encountered a similar like issue? ...

Hey gang, good day to all of you.  I have had some issues predominately the APs were showing very high channel utilization, in the range of 70+%. I have made lots of changes, such as lowering data rates, Event Driven RRM, Avoid Cisco AP Load, Band Select, Optimized Roaming, Aggressive Load Balancing and some other modifications as well.  On the end user client I saw huge benefits on the 2.4 GHz spectrum in regards to being able to get a much higher data throughput and better network operation. Additionally i have gone to the extend of shutting down a good portion of my 2.4 Radios and this begs this question. On the controller under wireless 802.11bg/n i see the shut down APs and under detail I still see the Chanel Utilization, which was the value prior to me shutting down some of my radios on the network.   Also when I capture the running-config and I analyze the same information on Analyzer, I still see the utilization percentage, is this how it is supposed to work?  do those counters reset after some time?  Maybe I need to restart RRM or something? even though I have it refresh every so often? Your help would be greatly appreciated. ... View more
