16 If using a dual-radio model access point, refer to the Mesh Timeout drop-down menu (from within
the Radio Configuration screen) to define whether one of the access point’s 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.
17 Click Apply to save any changes to the Radio Configuration screen. Navigating away from the screen
without clicking Apply results in all changes to the screens being lost.
CAUTION
When defining a Mesh configuration and changes are saved, the mesh network temporarily goes down.
The mesh network is unavailable because the access point radio goes down when applying the changes. This
can be problematic for users making changes within a deployed mesh network. If updating the mesh network
using a LAN connection, the access point applet loses connection and the connection must be re-instated. If
updating the mesh network using a WAN connection, the applet does not lose connection, but the mesh
network is unavailable until the changes have been applied.
18 Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the settings
displayed on the Radio Configuration screen to the last saved configuration.
19
Click Logout to securely exit the access point applet. A prompt displays confirming the logout before
the applet is closed.
Once the target radio has been enabled from the Radio Configuration screen, configure the radio’s
properties by selecting it from the Altitude 35xx menu tree.
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 MUs, but MU's can
only communicate amongst themselves using the access
point. Disabled is the default value.
Upload 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.
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 seconds). This allows the
client bridge (radio 1) to roam without dropping the MU's
associated to radio 2. The disadvantage is that radio 2
may beacon for the 45 second timeout period and have to
drop associated MU's because radio 1 could not establish
its uplink.
