Figure 19. WLAN Mesh Services
In the Figure 19, a client is associated with a Mesh AP and an AP without a wired interface to the network. The Mesh AP
is configured to communicate with a Mesh Portal AP and an AP with wired connectivity to an WSS. Communication
between the Mesh AP and the Mesh Portal AP takes place through a secure radio link (a Mesh Link). When associated
with the Mesh AP, the client establishes the same connectivity to the network as a Mesh AP with a wired link.
The Mesh AP and Mesh Portal AP are dual-radio APs. One radio (for example, the 802.11a radio) can be used for Mesh
Link communications, use an SSID reserved for this purpose. The Mesh AP can use the other radio for client associa-
tions (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,
the AP searches for an AP beaconing the mesh services SSID. The AP 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.
Note. WLAN mesh services is supported ONLY on the Series 2332
access points.
