Configure Path Method Root Path Metric Settings

About this task

Use the Path Method Root Path Metric screen to set a profile's mesh point root path scan settings.

To define the path method root path metric:

Procedure

  1. Select the Path Method Root Path Metric tab.
  2. Set the following values (common to both 2.4 GHZ and 5.0/4.9 GHz):
    Channel Width Set the channel width the mesh point's automatic channel scan assigns to the selected radio. Available options include:
    • Automatic – Defines the channel width is calculated automatically. This is the default value.
    • 20 MHz – Sets the width between two adjacent channels as 20 MHz.
    • 40 MHz – Sets the width between two adjacent channels as 40 MHz.
    • 80 MHz - Sets the width between two adjacent channels as 80 MHz for 802.11ac access points.
    Priority Meshpoint Configure the mesh point monitored for automatic channel scans. This is the mesh point assigned priority over other available mesh points. When configured, a mesh connection is established with this mesh point. If not configured, a mesh point is automatically selected. This setting is disabled by default.
    Meshpoint: Path Minimum Set the minimum path metric (from 100 - 20,000) for mesh connection establishment. The default setting is 1000.
    Meshpoint: Path Metric Threshold Configure a minimum threshold (from 800 - 65535) for triggering an automatic channel selection for mesh point selection. The default is 1500.
    Meshpoint: Tolerance Period Configure a duration to wait before triggering an automatic channel selection for the next mesh hop. The default is one 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 setting is 5.
    Meshpoint Root: Off-channel Duration Define the duration (from 20 - 250 milliseconds) for scan dwells on each channel, when performing an off channel scan. The default setting is 50 milliseconds.
    Meshpoint Root: Channel Switch Delta Configure the delta (from 5 - 35 dBm) that triggers a mesh point root automatic channel selection when exceeded. The default setting is 10 dBm.
    Meshpoint Root Off-channel Scan Frequency Configure the duration (from 1 -60 seconds) between two consecutive off channel scans for mesh point 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. Select OK to save the updates.
    Select Reset to revert to the last saved configuration.
