Hi,
In this Cisco youtube video, https://www.youtube.com/watch?v=8RAXFwVr-9c about site tags, at 1:58 there is a mention of using multiple site tags for load balancing and acceptable resource useage.
Is there an issue with using the same Flex Profile on multiple sites? We will have about 150 sites configured on the controller when we are done.
Thanks,
Peter.

when looking at the same video you must have passed 1:30
there you see flex-profiles assigned to multiple site-tags, it this the information you are looking for?
so yes, flex-profiles are reusable
be aware at 1:12 is mentioned properties specific to PHYSICAL site are part of the flex-profile. So that's the limitation

Hi,
I am aware that flex profiles are reusable. I used the same profile in over 100 sites, so when BG mentioned that there can be resourcing issues, I wanted to know if my configuration is sub-optimal.
I also notice that there is a limit of 100 aps per site. Any idea why this is?
Cheers,
Peter.

It has to do with bandwith and latency requirements from remote-site to central-site
look at the Enterprise Mobility 8.1 Design Guide
FlexConnect APs are deployed at the Branch site and managed from the Data Center over a WAN link. It is highly recommended that the minimum bandwidth restriction remains 24 kbps per AP with the round trip latency no greater than 300 ms. (see Table 7-3 ).
The maximum transmission unit (MTU) must be at least 500 bytes.
Data | 64 kbps | 300 ms | 5 | 25 |
Data | 640 kbps | 300 ms | 50 | 1000 |
Data | 1.44 Mbps | 1 sec | 50 | 1000 |
Data + Voice | 128 kbps | 100 ms | 5 | 25 |
Data + Voice | 1.44 Mbps | 100 ms | 50 | 1000 |
Data + Flex AVC | 75 Kbps | 300 ms | 5 | 25 |
The primary design requirements are:
