My co-worker typically brings up IP space management when discussing flex connect/hreap. Overprovisioning subnets for usage that may never come, or worse finding out that you under provisioned for that event you never heard of. Maybe not an issue for most or anyone.

About 4,300 students and around 500 APs. There have been some bugs which were annoying but usually there were workarounds. If you roam between Residence Life buildings the IPs for the device will change since we have different subnets in different Residence Life buildings. But the devices change IPs when they move from the Residence Life to the Main Campus (local or non-FlexConnect) and that has not caused any complaints. > On Apr 19, 2017, at 12:21 PM, Dennis Xu <d...@uoguelph.ca> wrote: > > For Cisco customers, has anyone done large deployment with FlexConnect mode APs? With the large capacity wireless controllers like 8540, all our wireless clients are going to terminate layer 3 at the same switch where the 8540 controlelr is connected to and that switch will have lots of ARP entries. The best practice for SUP720's ARP table size from Cisco is only 30k, and SUP2T can handle 100K ARP but still not sure if a single switch can serve large number of concurrent wireless users. FlexConnect has a good idea to spread wireless users across the network, but not sure if this solution is suitable for large deployment and if someone has success story with it. > > Thanks. > > Dennis Xu > University of Guelph > d...@uoguelph.ca > www.uoguelph.ca/ccs > > ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. --- Bruce Curtis bruce.cur...@ndsu.edu Certified NetAnalyst II 701-231-8527 North Dakota State University ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
