I’ve been told by two individuals from different VARs that it is not a good idea to mix generations of APs within an area due to RRM, but it’s OK to mix a 2700/3700 or 2800/3800/1815.
From the 9120 deployment guide: Mixing access points of different models and types The Catalyst 9120 is a very advanced access point supporting Wi-Fi 6 features along with unique features such as dual 5 GHz and advanced RF detection using Cisco custom RF ASIC silicon. For this reason, it is not recommended that you mix access point models, sometimes called “salt and pepper,” as it would diminish the performance of the Cisco DNA network, degrading many of our advanced features and perhaps introducing a suboptimal performance. For this reason, if you have a mixture of AP types, it is recommended that you group like access points together (for example, AP-3800s on, say, one floor and Cisco Catalyst 9120s on another) and refrain from mixing them. We’re currently working on a replacement plan to eliminate 1,800 3500s/2600s and hoping that 9120s will be in the picture for that, so looking forward to hearing feedback on them. Also hoping to get 9130s in our large auditorium before graduation.

My biggest concern is having to move to new code, but I know we all need to upgrade at some point. Any experience good or bad is appreciated. -- Thanks, Jason Becker Network Engineer 3 4480 Clayton Ave, St. Louis, MO 63110 Mail stop 8218-45-1200 •: 314.935.5006 | Ë: 618.363.2900 | •:[email protected]<mailto:[email protected]> ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
