Adding and Editing ACS Path Method Root Path Metric Configuration

Procedure

  1. Select the Path Method Root Path Metric tab to calculate root path metrics.

  2. Set the following Path Method Root Path Metric values.

    These descriptions apply to both the 2.4 GHz and 5.0/4.9 GHz frequencies.

    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.

    Meshpoint: Path Minimum

    Set the minimum path metric (from 100 - 20,000) for establishing mesh connections. The default setting is 1000.

    Meshpoint: Path Metric Threshold

    Configure a minimum threshold (from 800 - 65535) for triggering an automatic channel selection for meshpoint selection. The default is 1500.

    Meshpoint: Tolerance Period

    Configure the duration to wait before triggering an automatic channel selection for the next hop. The default is 1 minute.

    Meshpoint Root: Sample Count

    Set the number of scans (from 1- 10) for data collection before a mesh point root is selected. The default is 5.

    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. The default is 10 dBm.

    Meshpoint Root: Off-channel Scan Frequency

    Configure the duration (from 1 -60 seconds) between two consecutive off channel scans for meshpoint root. The default is 6 seconds.

    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. The default is 30 minutes.
  3. Click OK to save the changes made to the mesh point configuration.

    Click Reset to revert to the last saved configuration.
