Viewing the Channel Plan History

The Unified Switch stores channel assignment information for the APs it manages. To access the Channel Plan History
information, click the AP Management > RF Management > Channel Plan History tab.
The Cluster Controller switch that controls the cluster maintains the channel history information for all switches in the cluster.
On the Cluster Controller, the page shows information about the radios on all APs managed by switches in the cluster that
are eligible for channel assignment and were successfully assigned a new channel.
Table 271 describes the Channel Plan History fields.

Description
This field determines how often the switch runs the power adjustment algorithm. The algorithm
runs automatically only if you set the power adjustment mode to Interval.
Note: This setting gets applied to both radios of the AP.

Table 271: Channel Plan History

Description
The 5 GHz and 2.4 GHz radios use different channel plans, so the switch tracks the channel
history separately for each radio. The channel information that displays on the page is only for
the radio you select.
This field shows whether the switch is using the automatic channel adjustment algorithm on
the AP radios.
The number in this field indicates the most recent iteration of channel plan adjustments. The
APs that received a channel adjustment in previous iterations cannot be assigned new
channels in the next iteration to prevent the same APs from being changed time after time.
On the AP Management > RF Management > Configuration tab, you can set the history
depth to control the maximum number of iterations stored and displayed in the channel plan
history.
Shows the date and time when the channel plan algorithm last ran.
Note: To set the system time on the switch, you must use SNTP, which is disabled by
default. From the Web interface, you configure the SNTP client and server information from
the pages in the LAN > Administration > System > SNTP folder. From the CLI, use the
sntp commands in Global Config mode.
