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
“Configuring mesh networking support” on page 363.
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 Mesh Timeout value is not available on a single-radio access point,
since the radio would have to stop beaconing and go into scan mode to determine if a base
bridge uplink is lost. The following drop-down menu options are available:
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.
For a detailed overview on mesh networking and how to configure the radio for mesh
networking support, see
“Configuring mesh networking support” on page 363.
8. Click the Client Bridge Signal Monitor to enable the device to monitor the signal strength of the
base bridge it is connected to. If the signal strength falls below a configurable threshold, the
link to the existing base bridge is dropped and a connection to the base bridge with the
stronger signal is established.
Disabled 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 Clients, but Client's
can only communicate amongst themselves using the access point.
Disabled is the default value.
Uplink Detect 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.
Enabled 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 Client's associated to radio 2. The disadvantage is that radio 2
may beacon for the timeout period and have to drop associated Client's
because radio 1 could not establish its uplink. The default timeout period is
45 seconds.
