An access point can be configured to be a part of a meshed network. A mesh network is one where nodes in the network can communicate with each where each node can maintain more than one path to its peers. Mesh networking enables users to access broadband applications anywhere, including moving vehicles, by providing robust, reliable, and redundant connectivity to all the members of the network. When one of the nodes in a mesh network becomes unavailable, the other nodes in the network can still communicate with each other directly or through intermediate nodes.
Mesh point is the name given to a device that is a part of a meshed network.
Use the Mesh Point screen to configure or override the parameters that set how this device behaves as a part of the mesh network.
To set or override a profile's mesh point configuration:
MeshConnex Policy |
Provide a name for the Mesh Connex Policy. Use the Create icon to create a new Mesh Connex Policy. To edit an existing policy, select it from the dropdown and click the Edit icon. For more information on creating or editing a Mesh Connex Policy, see MeshConnex Policies. |
Is Root | Select the root behavior of this access point. True means that this access point is a root node for this mesh network, and False means that it is not a root node. A root mesh point is defined as a mesh point that is connected to the WAN and provides a wired backhaul to the network. |
Root Selection Method |
Use the drop-down menu to determine whether this mesh point is the root or non-root mesh point. Select either None (the default setting) or auto-mint. |
Set as Cost Root | Select this option to set the mesh point as the cost root for mesh point root selection. This setting is disabled by default. |
Monitor Critical Resources |
Select this option to enable critical resource monitoring for this mesh point. |
Monitor Primary Port Link |
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. |
Wired Peer Exclude | Select this option to exclude wired peers when creating mesh links. |
Path Method |
Select the method used for path selection in a mesh network. Available options include:
|
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.The default setting is 0 dB. |
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. The default setting is 1 dB |
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. The default setting is 1 second. |
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
An AP 7161 model access point can be deployed as a vehicular mounted modem (VMM) to provide wireless network access to a mobile vehicle such as a car or train.. 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 Considerations.Preferred Neighbor | Specify the MAC address of a preferred neighbor for this mesh point. |
Preferred Root | Specify the MAC address of a 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. |
Channel Width | Set the channel width the
meshpoint‘s automatic channel scan assigns to the selected
radio. Available options include:
|
Priority Meshpoint | Configure the meshpoint monitored for automatic channel scans. This is the meshpoint assigned priority over other available mesh points. When configured, a mesh connection is established with this mesh point. If not configured, a meshpoint is automatically selected. |
Off-channel Duration | Set the duration (from 20 - 250 milliseconds) the scan dwells on each channel when performing an off channel scan. |
Off-channel Scan Frequency | Set the duration (from 1- 60 seconds) between two consecutive off channel scans. |
Meshpoint Root: Sample Count | Configure the number of scan samples (from 1- 10) for data collection before a mesh channel is selected. |
Meshpoint Root: Channel Hold Time | Configure the duration (from 0 - 1440 minutes) to remain on a channel before channel conditions are reassessed for a possible channel change. Set this value to zero (0) to prevent an automatic channel selection from occurring. |
Channel Width | Set the channel width the
meshpoint‘s automatic channel scan assigns to the selected
radio. Available options include:
|
Priority Meshpoint | Configure the meshpoint monitored for automatic channel scans. This is the meshpoint assigned priority over other available mesh points. When configured, a mesh connection is established with this mesh point. If not configured, a meshpoint is automatically selected. |
SNR Delta | Set the signal to noise (SNR)
ratio delta (from 1 - 100 dB) for mesh path selections.
When path selection occurs, the defined value is utilized for selecting the optimal path. A better candidate, on a different channel, must have a signal strength that exceeds this delta value when compared to the signal strength of the next hop in the mesh network. The default setting is 5 dB. |
SNR Threshold | Set the SNR threshold for mesh
path selections (from -100 to 0 dB). If the signal strength of the next mesh hop falls below this set value, a scan is triggered to select a better next hop. the default setting is -65 dB. |
Off-channel Duration | Set the duration (from 20 - 250 milliseconds) the scan dwells on each channel when performing an off channel scan. The default is 50 milliseconds. |
Channel Width | Set the channel width the
meshpoint‘s automatic channel scan assigns to the selected
radio. Available options include:
|
Priority Meshpoint | Configure the meshpoint monitored for automatic channel scans. This is the meshpoint assigned priority over other available mesh points. When configured, a mesh connection is established with this mesh point. If not configured, a meshpoint is automatically selected. The default setting is None. |
Meshpoint: Path Minimum | Set the minimum path metric (from 100 - 20,000) for establishing mesh connections. |
Meshpoint: Path Metric Threshold | Configure a minimum threshold (from 800 - 65535) for triggering an automatic channel selection for meshpoint selection. |
Meshpoint: Tolerance Period |
Configure the duration in seconds to wait before triggering an automatic channel selection for the next hop. |
Meshpoint Root: Sample Count | Set the number of scans (from 1- 10) for data collection before a mesh point root is selected. |
Meshpoint Root: Off-channel Duration | Configure the duration (from 20 - 250 milliseconds) that the scan dwells on each channel when performing an off-channel scan. The default is 50 milliseconds. |
Meshpoint Root: Channel Switch Delta | Configure the delta (from 5 - 35 dBm) that triggers a meshpoint root automatic channel selection when exceeded. |
Meshpoint Root: Off-channel Scan Frequency | Configure the duration (from 1 -60 seconds) between two consecutive off channel scans for meshpoint root. |
Meshpoint Root: Channel Hold Time | Set the minimum duration (from 0 - 1440 minutes) to remain on a selected channel before channel conditions are reassessed for a possible channel change. Set this value to zero (0) to prevent an automatic channel selection from occurring. |
