8. Click the Auto Channel Selection tab to configure the parameters for the Mesh Connex Auto Channel Selection policy.
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 – Indicates 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.
• pcr-weighted – Select this to choose a neighbor path based on the packet completion rate
from a neighbor device. A device with a higher packet completion rate is chosen over a
device with a lower packet completion rate.
• snr-leaf – Select this to indicate the path with the best signal to noise ratio is always
selected.
Preferred Neighbor Enter the MAC address of the mesh point device that is the preferred neighbor.
Preferred Root Enter the MAC address of the mesh point root that is the preferred root.
Preferred Interface From the drop-down menu, select the preferred interface for forming a mesh network.
Minimum Threshold Enter the minimum value for SNR above which a candidate for the next hop in a dynamic mesh
network is considered for selection. 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 value that is higher than the value configured here. This field along with the
Minimum Threshold and Sustained Time Period is used to dynamically select the next hop in
a dynamic mesh network.
Sustained Time
Period Indicates the duration (in minutes) 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.
NOTE: With this release of the 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
Vehicle Mounted Modem (VMM) Deployment Consideration on page
