Intermediate APs
Intermediate APs (AP150 or OAP180) connect upstream to the gateway AP and down-
stream to other intermediate APs or leaf APs via a wireless backhaul link. Interme-
diate AP have no wired connection to the network and are configured for wireless
mode.
Leaf APs
Leaf APs (AP150 or OAP180), at the edge of the Enterprise Mesh network connect
upstream to a gateway or intermediate AP and provide service to 802.11 clients. Leaf
APs are configured for wireless mode.
Equipment Requirements
When designing an Enterprise Mesh configuration, use either a MC3000, MC41000, or
MC5000 controller and APs based on their capabilities, as shown in Table 20.
Table 20: AP Capabilities in an Enterprise Mesh
The following additional design guidelines apply:
Enterprise Mesh APs support only L2 connectivity to the controller.
QoS is not supported on the wireless backhaul.
Bridged mode is not supported for Enterprise Mesh—only tunneled mode is
supported.
Dynamic discovery is not supported.
From the gateway, a maximum of 3 hops is supported between the gateway and
leaf APs with no more than 7 APs per cloud, (for example,1 gateway with 2
wireless APs, and 4 leaf APs is supported).
Minimum channel separation guidelines are to use non-overlapping channels.
The design must have uncompromising LoS between any two backhaul hops.
