Refer to the following to configure Mesh Point Root Path Preference parameters:
Click the Auto Channel Selection tab to configure the parameters for the Mesh Connex Auto
Channel Selection policy. The following screen displays:
Path Method 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
(only on sslected models). 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.
Minimum Threshold 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.
Signal Strength Delta 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.
Sustained Time Period 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.
SNR Delta Range Select the root selection method hysteresis (from 1 - 100dB) SNR delta range a candidate must
sustain. The default setting is 1 dB.
Preferred Neighbor Enter the MAC address of the preferred neighbor for this mesh point.
Preferred Root Enter the MAC address of the preferred mesh root for this mesh point.
Preferred Interface 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.
