Design Considerations
There is no current software limitation of how many MAPs per RAP you can configure. However,
it is suggested that you limit this to 20 MAPs per RAP.
• Number of controllers
– The number of controllers per mobility group is limited to 72.
• Number of mesh access points supported per controller. Refer to “Controller Planning”in the next
section.
Controller Planning
The following items affect the number of controllers required in a mesh network:
• Mesh access points (RAPs and MAPs) in the network.
The wired network that connects the RAPs and controllers can affect the total number of access
points supported in the network. If this network allows the controllers to be equally available to all
access points without any impact on WLAN performance, the access points can be evenly
distributed across all controllers for maximum efficiency. If this is not the case, and controllers are
grouped into various clusters or PoPs, the overall number of access points and coverage are reduced.
For example, you can have 72 of a Cisco 4400 series controller in a mobility group, and each 4400
series controller supports 100 local access points. This gives a total number of 7200 possible access
points per mobility group.
• Number of mesh access points (RAPs and MAPs) supported per controller. Refer to Table 10.
For clarity, non-mesh access points are referred to as local access points in this document.
