Override Path Method SNR Settings

About this task

To set or override the MeshPoint Path Method SNR settings:

Procedure

  1. Select the Path Method SNR tab.
    Click to expand in new window
    Profile Overrides - MeshPoint - ACL - Path Method SNR Tab
  2. Set the following for both 2.4 GHz and 5.0/4.9 GHz bands:
    Channel Width Set the channel width the meshpoint‘s automatic channel scan assigns to the selected radio. Available options include:
    • Automatic – The channel width is calculated automatically. This is the default value.
    • 20 MHz – Sets the width between adjacent channels as 20 MHz.
    • 40 MHz – Sets the width between adjacent channels as 40 MHz.
    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 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.
  3. Click OK to save the changes.
    Click Reset to revert to the last saved configuration.
