feature enables the controller to automatically form an RF group with other

controllers. The group dynamically elects a leader to optimize RRM parameter settings, such as
channel and transmit power assignment, for the group.

Step 17

If you want the controller to receive its time setting from an external Network Time Protocol (NTP)
server when it powers up, enter

yes

to configure an NTP server. Otherwise, enter

Configure a NTP server now? [YES][no]: no

Step 18

If you entered

in the previous step and want to manually configure the system time on your controller
