Use the Dynamic Root Selection screen to refine channel scans, set the scan duration, whether scans are conducted off-channel, scan sample size and channel hold time.
To define a profile's mesh point dynamic root selection:
Select the Configuration tab from the Web UI.
Select Profiles from the Configuration tab.
Select Manage Profiles from the Configuration > Profiles menu.
Select Mesh Point.
Refer to the Mesh Point screen to view existing Mesh Points. If an existing Mesh Point configuration does not meet your requirements, select the Add button to create a new mesh point configuration or the Edit button to modify the parameters of an existing mesh point configuration. The Mesh Point screen displays the Settings tab by default.
Select the Auto Channel Selection tab.
The Dynamic Root Selection screen displays by default.
Set the following values (common to both 2.4 GHZ and 5.0/4.9 GHz):
|
Channel Width |
Set the channel width the meshpoint'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 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.This setting is disabled by default |
|
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 |
|
Off-channel Scan Frequency |
Set the duration (from 1- 60 seconds) between two consecutive off channel scans. The default is 6 seconds. |
|
Meshpoint Root - Sample Count |
Configure the number of scan samples (from 1- 10) performed for data collection before a mesh channel is selected. The default is 5. |
|
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. The default setting is 30 minutes. |
Select OK to save the updates to the Mesh Point's dynamic root selection configuration. Select Reset to revert to the last saved configuration.
