Frank, Airwave polls for data every 10 minutes. I have 10-Gig connections on my large controllers so they are not a bottleneck. If the connection were the problem, I could upgrade to a 20-Gig PortChannel. The specification sheet on my large controllers lists 20Gps Firewall throughput, 512 Max APs and 8192 Max Users.
According to my latest daily report, here are the top APs by bandwidth: Most Utilized by Bandwidth Rank<https://amp.liberty.edu/nf/?total_bw_1_sort_field=rank&total_bw_1_reverse=1&id=312><https://amp.liberty.edu/nf/?total_bw_1_sort_field=rank&total_bw_1_reverse=1&id=312> AP/Device<https://amp.liberty.edu/nf/?total_bw_1_sort_field=name&total_bw_1_reverse=0&id=312> Number of Users<https://amp.liberty.edu/nf/?total_bw_1_sort_field=total_users&total_bw_1_reverse=0&id=312> Max Simultaneous Users<https://amp.liberty.edu/nf/?total_bw_1_sort_field=max_simul_users&total_bw_1_reverse=0&id=312> Total Bandwidth (MB)<https://amp.liberty.edu/nf/?total_bw_1_sort_field=total_bw&total_bw_1_reverse=0&id=312> Average Bandwidth (kbps)<https://amp.liberty.edu/nf/?total_bw_1_sort_field=avg_bw&total_bw_1_reverse=0&id=312> Location<https://amp.liberty.edu/nf/?total_bw_1_sort_field=syslocation&total_bw_1_reverse=0&id=312> Controller<https://amp.liberty.edu/nf/?total_bw_1_sort_field=controller_name&total_bw_1_reverse=0&id=312> Folder<https://amp.liberty.edu/nf/?total_bw_1_sort_field=ap_folder_path&total_bw_1_reverse=0&id=312> Group<https://amp.liberty.edu/nf/?total_bw_1_sort_field=ap_group_name&total_bw_1_reverse=0&id=312> 1 CED13-203C-AP<https://amp.liberty.edu/ap_monitoring?id=98> 51 12 98099.45 9301.28 Not Available LU13-WLC-01<https://amp.liberty.edu/ap_monitoring?id=3> Top > East Campus > East 1-19 & Clubhouses > East Dorm 13<https://amp.liberty.edu/ap_list?ap_folder_id=23> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> 2 CED25-401-AP<https://amp.liberty.edu/ap_monitoring?id=360> 59 13 25648.17 2431.83 Not Available LU24-WLC-01<https://amp.liberty.edu/ap_monitoring?id=4> Top > East Campus > East 25-30 > East Dorm 25<https://amp.liberty.edu/ap_list?ap_folder_id=35> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> 3 LI-C-417<https://amp.liberty.edu/ap_monitoring?id=469> 59 15 22187.24 2103.68 Not Available LI-WLC-01<https://amp.liberty.edu/ap_monitoring?id=439> Top > Lynchburg Inn > Building C<https://amp.liberty.edu/ap_list?ap_folder_id=94> Lynchburg Inn<https://amp.liberty.edu/ap_group_monitoring?id=3> 4 D07-221-AP<https://amp.liberty.edu/ap_monitoring?id=148> 52 10 16713.03 1584.64 Not Available LU13-WLC-01<https://amp.liberty.edu/ap_monitoring?id=3> Top > Dorms 1-16 - Circle > Dorm 07<https://amp.liberty.edu/ap_list?ap_folder_id=54> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> 5 LI-C-427<https://amp.liberty.edu/ap_monitoring?id=474> 51 12 15596.36 1478.77 Not Available LI-WLC-01<https://amp.liberty.edu/ap_monitoring?id=439> Top > Lynchburg Inn > Building C<https://amp.liberty.edu/ap_list?ap_folder_id=94> Lynchburg Inn<https://amp.liberty.edu/ap_group_monitoring?id=3> 6 CED25-402-AP<https://amp.liberty.edu/ap_monitoring?id=400> 38 8 15572.27 1476.48 Not Available LU24-WLC-01<https://amp.liberty.edu/ap_monitoring?id=4> Top > East Campus > East 25-30 > East Dorm 25<https://amp.liberty.edu/ap_list?ap_folder_id=35> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> 7 CED19-202C-AP <https://amp.liberty.edu/ap_monitoring?id=80> 59 12 15176.76 1438.98 Not Available LU13-WLC-01<https://amp.liberty.edu/ap_monitoring?id=3> Top > East Campus > East 1-19 & Clubhouses > East Dorm 19<https://amp.liberty.edu/ap_list?ap_folder_id=29> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> 8 D31-102-AP<https://amp.liberty.edu/ap_monitoring?id=425> 62 13 12270.66 1163.44 Not Available LU24-WLC-01<https://amp.liberty.edu/ap_monitoring?id=4> Top > Dorms 24-33 - Senior & Quads > Dorm 31<https://amp.liberty.edu/ap_list?ap_folder_id=80> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> 9 D19-105-AP<https://amp.liberty.edu/ap_monitoring?id=393> 69 14 11725.07 1111.71 Not Available LU24-WLC-01<https://amp.liberty.edu/ap_monitoring?id=4> Top > Dorms 17-23 - Hill > Dorm 19<https://amp.liberty.edu/ap_list?ap_folder_id=67> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> 10 D18-211-AP<https://amp.liberty.edu/ap_monitoring?id=355> 91 15 11296.28 1071.05 Not Available LU24-WLC-01<https://amp.liberty.edu/ap_monitoring?id=4> Top > Dorms 17-23 - Hill > Dorm 18<https://amp.liberty.edu/ap_list?ap_folder_id=66> Main Aruba Access Points<https://amp.liberty.edu/ap_group_monitoring?id=1> I agree that a controller is the best way for most schools to manage a large number of APs effectively. The only exception I have heard is one university that is using a lot of custom applications to control the "fat" APS much like a controller would. They still do not have the control that the controller firewall gives us. Bruce From: Frank Bulk [mailto:[email protected]] Sent: Saturday, February 28, 2009 10:43 AM Subject: Re: Aerohive 340AP Bruce, and perhaps others: If you do 5-minute polling of your APs, what's the highest throughput you've seen on your APs? And looking at your controllers, what's the highest average bandwidth/AP you've seen (i.e. if you saw 250 Mbps on a controller that serves 500 APS, that would be 0.5 Mbps)? It's my personal bias that even peak product throughputs don't touch close to what a properly sized controller theoretically could handle.

(NS) Sent: Saturday, February 28, 2009 9:09 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Aerohive 340AP Todd, I'm not sure why you would say that. We now have almost 600 802.11n APs on 3 controllers that are managed centrally from the master controller. We can handle up to 500 APs per controller (2000 per chassis). This allows you to standardize configurations & OS versions. We are supplementing this with Airwave Wireless Management Suite for monitoring. We moved from 450 Cisco 1231G "fat" APs. The centralized solution scales much better for us. From: Smith, Todd [mailto:[email protected]] Sent: Friday, February 27, 2009 4:28 PM Subject: Re: Aerohive 340AP I reviewed their product in our environment and it worked pretty well. I don't think that we are going to be purchasing anything this year due to the economic downturn but they are on my short list as well as Xirrus and Meru simply because they use non-standard architectures. My personal opinion is that centralized controller environments don't scale very well when you are considering large 802.11n rollouts.

Competitors like to poke holes at their product, but my (un-tested) impression is that it's pretty solid. If you ask for references, they do have some small to medium-sized build outs, but I'm not sure if they have any 500+ AP installations, yet.

Is interesting- they are a controller-less model, that *seems* to scale and compete with controller-based functionality based on the glossy. No idea how they are on the likes of fast roaming, etc. But part of my brain yearns for the days when there were no controllers, and wireless life was a lot simpler. (You never see WLAN controllers in Norman Rockwell paintings). Is anyone using Aerohive, even on a small scale? Lee Lee H.
