Figure 19: After Channel Management Enable
Whe
n automatic channel assignment is enabled, the Channel Manager periodically maps radio
channels used by clustered access points and, if necessary, re-assigns channels on clustered APs to
reduce interference (with cluster members or other APs outside the cluster).
Note: Channel Management overrides the default cluster behavior, which is to
synchro
nize radio channels of all APs across a cluster. When Channel Management is
enabled, the radio Channel is not synced across the cluster to other APs. See the note
under Radio Settings in “Settings Shared in the Cluster Configuration
”.
Click Stop to stop automatic channel assignment. (No channel usage maps or channel
re-assignments will be made. Only manual updates will affect the channel assignment.)
Viewing Current Channel Assignments and Setting Locks
The "Current Channel Assignments" shows a list of all access points in the cluster by IP Address. The
display shows the band on which each AP is broadcasting, 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. Details
about Current Channel Settings are provided below.
Field Description
IP Address Specifies the IP Address for the access point.
Radio Indicates the MAC address of the access point.
Band Indicates the band (b/g or a) on which the access point is broadcasting.
Channel Indicates the radio Channel on which this access point is currently broadcasting.
Locked Click Locked if you want this access point to remain on the current channel.
When the “Locked” checkbox is checked (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. For 5GHz band, because of DFS function (See
“802.11h Regulatory Domain Control
”), you might fail to lock the channel for the
APs.
If you click Update, you will see that locked APs show the same channel for
"Current Channel" and "Proposed Channel". Locked APs will keep their current
channels.
Update Current Channel Settings (Manual Setting)
You can run a manual channel management update at any time by clicking Update under the Advanced
display.
