NOTE: With this release of Motorola Solutions WiNG software, an AP7161 model
access point can be deployed as a Vehicle Mounted Modem (VMM) to provide wireless
network access to a mobile vehicle (car, train, etc.). A VMM provides layer 2 mobility for
connected devices. VMM does not provide layer 3 services, such as IP mobility. For
VMM deployment considerations, see
Consideration.
Select this option to enable critical resource monitoring for this mesh point.
Select to enable monitoring of primary port link is enabled for this mesh connex policy. If
the primary port link is not present and if the device is a mesh root, it is automatically
changed to a non-root device. When the primary port link becomes available again, the
non-root device is changed back to a root device.
Select this option to exclude wired peers when creating mesh links.
From the drop-down menu, select the method to use for path selection in a mesh network.
The available options are:
• None – Select this to indicate no criteria used in root path selection.
• uniform – Select this to indicate that the path selection method is uniform. When
selected, two paths will be considered equivalent if the average value is the same for
these paths.
• mobile-snr-leaf – Select this if this access point is mounted on a vehicle or a mobile
platform (AP7161 models only). When selected, the path to the route will be selected
based on the Signal To Noise Ratio (SNR) to the neighbor device.
• snr-leaf – Select this to indicate that the path with the best signal to noise ratio is
always selected.
Enter the minimum value for SNR above which a candidate for the next hop in a dynamic
mesh network is considered. This field along with Signal Strength Delta and Sustained
Time Period are used to dynamically select the next hop in a dynamic mesh network.
Enter a delta value in dB. A candidate for selection as a next hop in a dynamic mesh
network must have a SNR higher than the value configured here. This field along with the
Minimum Threshold and Sustained Time Period are used to dynamically select the next
hop in a dynamic mesh network.
Enter the time duration in seconds (0 - 600) or minutes (0 - 10). This indicates the duration
that a signal must sustain the constraints specified in the Minimum Threshold and Signal
Strength Delta path hysteresis values. These values are used to dynamically select the
next hop in a dynamic mesh network.
Select the root selection method hysteresis (from 1 - 100dB) SNR delta range a candidate
must sustain. The default setting is 1 dB.
Root Path Preference
Enter the MAC address of the preferred neighbor for this mesh point.
Enter the MAC address of the preferred mesh root for this mesh point.
Select the preferred Interface for this mesh point. Select None to set no preferences. The
other interface choices are 2.4 GHz and 5 GHz.
