CAUTION
An Access Point in client bridge mode cannot use a WLAN configured with a Kerberos or EAP 802.1x
based security scheme, as these authentication types secure user credentials not the mesh network itself.
NOTE
Ensure you have verified the radio configuration for both Radio 1 and Radio 2 before saving the existing
settings and exiting the Radio Configuration screen.
Once the settings within the Radio Configuration screen are applied (for an initial deployment), the
current number of base bridges visible to the radio displays within the BBs Visible field, and the
number of base bridges currently connected to the radio displays within the BBs Connected field. If
this is an existing radio within a mesh network, these values update in real-time.
6 Click the Advanced button to define a prioritized list of Access Points to define Mesh Connection
links. For a detailed overview on mesh networking and how to configure the radio for mesh
networking support, see
7 If using a dual-radio model Access Point, refer to the Mesh Timeout drop-down menu to define
whether one of the radio's beacons on an existing WLAN or if a client bridge radio uses an uplink
connection. The following drop-down menu options are available:
Disabled
Uplink Detect
Enabled
NOTE
The Mesh Time Out variable overrides the Ethernet Port Time Out (EPTO) setting on the LAN page
when the Access Point is in bridge mode. As long as the mesh is down, the Access Point acts in accordance to
the Mesh Time Out setting regardless of the state of the Ethernet. However, if the Ethernet goes down and the
mesh link is still up, the EPTO takes effect.

When disabled, both radios are up at boot time and
beaconing. If one radio (radio 1) does not have a mesh
connection, the other radio (radio 2) is not affected. Radio
2 continues to beacon and associate MUs, but MUs can
only communicate amongst themselves using the Access
Point. Disabled is the default value.
When Uplink Detect is selected, the Access Point only
boots up the radio configured as a client bridge. The
Access Point boots up the second radio as soon as the
first mesh connection is established. However, if the client
bridge radio loses its uplink connection, the second radio
shuts down immediately. Uplink detect is the
recommended setting within a multi-hop mesh network.
If the mesh connection is down on one radio (radio 1), the
other radio (radio 2) is brought down and stops beaconing
after the timeout period (45–65535 seconds). This allows
the client bridge (radio 1) to roam without dropping the
MUs associated to radio 2. The disadvantage is that radio
2 may beacon for the timeout period and have to drop
associated MUs because radio 1 could not establish its
uplink. The default timeout period is 45 seconds.
