For MAPs that are in the network plan, but are not yet deployed and
managed by 3WXM, the channel number is changed to match the results
of channel assignment. However, the channel is not changed for MAPs
that are running in the live network and are being managed by 3WXM.
For these MAPs, 3WXM displays the channels that are in use on the live
MAPs.
To make the MAPs in the live network use the channels assigned by RF
Planning, deploy the configuration to the network. After deploying the
configuration with the new channel settings, the channel information on
the floor plan should match the channels assigned by RF Planning.
