In the illustration, a client is associated with a Mesh AP, which is a MAP 
without a wired interface to the network. The Mesh AP is configured to 
communicate with a Mesh Portal AP, a MAP with wired connectivity to a 
WX  switch.
Communication between the Mesh AP and the Mesh Portal AP takes 
place using over a secure radio link (a Mesh Link). When associated with 
the Mesh AP, the client has the same connectivity to the network as it has 
over a Mesh AP with a wired link.
The Mesh AP and Mesh Portal AP are dual-radio MAPs. One radio (for 
example, the 802.11a radio) can be used for Mesh Link communications, 
using an SSID reserved for this purpose, while the Mesh AP can use its 
other radio for client associations in the same manner as a non-Mesh AP.
The Mesh Portal AP beacons a mesh services SSID on the radio used for 
the Mesh Link. When the Mesh AP is booted, it searches for a MAP 
beaconing the mesh services SSID. It selects the Mesh Portal AP with the 
greatest signal strength, then establishes a secure connection to the 
Mesh Portal SSID. Once this connection is established, clients can 
associate with the Mesh AP.
WLAN mesh services is supported on MAP models MP-620 and MP-422 
only.
Configuring WLAN 
Mesh Services
The basic configuration process for WLAN mesh services consists of the 
following tasks:
„
Attaching the Mesh AP to the network and configuring mesh services.
„
Configuring a service profile for mesh services.
„
Setting security parameters to allow the Mesh AP to authenticate 
on the 
network.
„
Optionally configuring the Mesh Portal AP to emit link calibration 
packets to 
aid in positioning the Mesh AP.
„
Detaching the Mesh AP from the network and deploying it in its final 
location.
After the Mesh AP is installed in its final location, and it has established a 
connection to the Mesh Portal AP, it can be configured as any other MAP 
on the WX  switch.
