Section 9 - Clustering Multiple APs
Viewing Current Channel Assignments and Setting Locks
The
Current Channel Assignments
section shows a list of all access points in the cluster by IP Address. The display
shows the band on which each AP is broadcasting (a/b/g/n), the current channel used by each AP, and an option to
lock an AP on its current radio channel so that it cannot be re-assigned to another.
The following table provides details about Current Channel Assignments.
Field
Description
IP Address
Specifies the IP Address for the access point.
Radio
Identifies the MAC address of the radio.
Band
Indicates the band on which the access point is broadcasting.
Current
Indicates the radio Channel on which this access point is currently broadcasting.
Status
Shows whether the radio is up (on) or down (off).
Locked
Click
Locked
to force the access point to remain on the current channel.
When Locked is selected (enabled) for an access point, automated channel management
plans will not re-assign the AP to a different channel as a part of the optimization strategy.
Instead, APs with locked channels will be factored in as requirements for the plan.
If you click
Apply
, you will see that locked APs show the same channel for the Current
Channel and Proposed Channel fields. Locked APs will keep their current channels.
Table 61 - Channel Assignments
Viewing the Last Proposed Set of Changes
The
Proposed Channel Assignments
shows the last channel plan. The plan lists all access points in the cluster by IP
Address, and shows the current and proposed channels for each AP. Locked channels will not be re-assigned and the
optimization of channel distribution among APs will take into account the fact that locked APs must remain on their
current channels. APs that are not locked may be assigned to different channels than they were previously using,
depending on the results of the plan.
Field
Description
IP Address
Specifies the IP Address for the access point.
Radio
Indicates the radio channel on which this access point is currently broadcasting.
Proposed Channel
Indicates the radio channel to which this access point would be re-assigned if the Channel
Plan is executed.

Configuring 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 fine-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-configure the channel set used for assignments. If there are no fields
showing in the Advanced section, click the toggle button to display the settings that modify timing and details of the
channel planning algorithm.
