Section 9 - Clustering Multiple APs
Conguring Advanced Settings
The advanced settings allow you to customize and schedule the channel plan for the cluster. If you use Channel
Management as provided (without updating Advanced Settings), channels are automatically ne-tuned once every
hour if interference can be reduced by 25 percent or more. Channels will be re-assigned even if the network is busy.
The appropriate channel sets will be used (b/g for APs using IEEE 802.11b/g and a for APs using IEEE 802.11a).
The default settings are designed to satisfy most scenarios where you would need to implement channel
management.
Use Advanced Settings to modify the interference reduction potential that triggers channel re-assignment, change
the schedule for automatic updates, and re-congure the channel set used for assignments. If there are no elds
showing in the Advanced section, click the toggle button to display the settings that modify timing and details of the
channel planning algorithm.
Field Description
Change channels
if interference is
reduced by at least
Specify the minimum percentage of interference reduction a proposed plan must achieve in
order to be applied. The default is 75 percent.
Use the drop-down menu to choose percentages ranging from 5 percent to 75 percent.
This setting lets you set a gating factor for channel re-assignment so that the network is not
continually disrupted for minimal gains in efciency.
For example, if channel interference must be reduced by 75 percent and the proposed
channel assignments will only reduce interference by 30 percent, then channels will not be
re-assigned. However; if you re-set the minimal channel interference benet to 25 percent
and click Apply, the proposed channel plan will be implemented and channels re-assigned
as needed.
Determine if there
is better set of
channels every
Use the drop-down menu to specify the schedule for automated updates.
A range of intervals is provided, from 30 Minutes to 6 Months
The default is 1 Hour (channel usage re-assessed and the resulting channel plan applied
every hour).
Table 70 - Advanced Channel Management Settings
Click Apply under Advanced settings to apply these settings.
Advanced settings will take effect when they are applied and inuence how automatic channel management is
performed.
Channel Management supports Clustering Options, Single IP Management, and Secure Join Clustering. For
more details, please refer to the following sections: “Cluster Options” on page 111, “Single IP Management” on page
111, and “Secure Join Clustering” on page 111.
Note: Currently, Clustering Options, Single IP Management, and Secure Join Clustering features
are available only in DWL-3610AP and DWL-6610B1AP.
Viewing Wireless Neighbourhood Information
The Wireless Neighbourhood shows up to 20 access points per radio within range of every member of the cluster,
shows which access points are within range of which cluster members, and distinguishes between cluster members
and non-members.
Note: The Wireless Neighbourhood page shows up to 20 access points per radio. To see all the
access points detected on a given cluster access point, navigate to that cluster member’s web
interface and go to the Status > Neighbouring Access Points page.
For each neighbour access point, the Wireless Neighbourhood view shows identifying information (SSID or Network
Name, IP Address, MAC address) along with radio statistics (signal strength, channel, beacon interval). You can click
on an AP to get additional statistics about the APs in radio range of the currently selected AP.
