Urgent for WLC-AP management

    Hi Team,

    We are getting very close to finalizing the design for WLC and Access Point Management in Spectrum for the upcoming release/s

    One confirmation we needed before we put the design in stone is the answer to the following two questions:


    • CISCO 65xx is currently being considered to be supported as part of first phase. Is there any other device family for CISCO WLC that the community wants us to consider?
    • What are the typical number of WLCs in environment and max no. of APs per WLC?


    Quick response to this (hopefully by many community members ) would be much appreciated.

    I have two Cisco 8510 WLC's running 7.6 code with over 2500+ 3502 and 3602i AP's

    Thanks! So approx 1250 APs per WLC?

    This will make my team so happy.


    When you say the Cisco 65xx, I assume you are actually referring to the WISM and/or WISM2 modules for the 65xx series?


    We currently are in the process of migrating away from legacy Cisco 4400-series controllers and first-gen WISM controllers toward almost entirely WISM2 controllers.  We do have a good number of 5508 controllers out there as well, though.


    We typically have them in a HA configuration where we have migrated to WiSM2 devices.  Where we have legacy devices, we have them in redundant pairs.


    We have approximately 20 - 25 sets of controllers.  Each set consists of a WISM2 and a WISM2 HA module.


    Number of APs varies by location but ranges from probably about 50 or 60 on the low side to about 400 on the high side.


    Please feel free to contact me directly offline if you would like further details.

    Hi Kiran,

    we use Cisco 5500 Series Wireless Controllers

    Hello All,


    Thanks so much for your responses. One last thing if people could confirm.


    What is the average number of AP's per WLC that you folks have. Is it typically in 100s or 1000s?

    Also, if some of you could comment on the TOTAL count of APs that would help with design for scale and scale testing too.
    Thanks again!

    We have 175 Cisco 5500 series WLCs and currently about 12k access points (will have around 15k access points when project is completed).

    Most our WLCs have around 70-75 APs but around 25% of the sites will have in the 100s of APs when we are done.

    Thanks so much Jeff! This is helpful.

    You 15K APs seem to be more on the higher side - based on my discussions with others and this forum, the typical number seems to be a few thousands.

    Can others jump in and confirm or correct my assessment?

    Hello Kiran,


    we've got a bunch of "smaller" customers with 2 to 10 controllers, all Cisco based.

    However, there is also large stuff with a bit more (similar to DCPS_Jeff), all numbers based on snmp information ignoring any possible redundancy:

    Cisco: ~60 controllers managing 8000+ access points resulting in ~130 APs per controller; types: 65xx WiSM, 5500 WLC, 440x WLC

    HP unified: ~35 controllers managing 5500+ access points resulting in ~155 APs per controller; type LSU3WCMD0


    Could you share some more details on the functionality currently planned? We're especially interested in cluster scenarios, were e.g. some APs disconnect from controller A and instantly connect to controller B leaviong the LRAD_DISASSOCIATED alarms on controller A. Such scenarios shall be handled out of the box (using condition correlation?).


    thanks and best regards,

    We have the following:


    Cisco 5508's,

    Cisco 5760's,

    Cisco 3850's.


    We have currently 100 or less AP's per controller.
