8. Click the Auto Channel Selection tab to configure the parameters for the Mesh Connex Auto Channel Selection policy.
The following screen displays:
Monitor Critical
Resource
Select this option to monitor critical resources. If a configured critical resource becomes
unavailable, the mesh point is removed from the mesh network.
Monitor Primary Port Link Select this option to indicate this mesh point monitors the link on the primary port. If the
link on the primary port becomes unavailable, the mesh network is brought down.
Wired Peer Exclude Select this option to exclude wired peers when creating mesh links.
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 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 Vehicle Mounted Modem (VMM) Deployment
Consideration on page 5-159.
