Setting Up Time Synchronization
Setting up NTP on AirWave
On the AMP Setup > Network page, locate the Network Time Protocol (NTP) section. The Network Time
Protocol is used to synchronize the time between AMP and your network reference NTP server. NTP servers
synchronize with external reference time sources, such as satellites, radios, or modems.
To disable NTP services, clear both the Primary and Secondary NTP server fields. Any problem related to
communication between AMP and the NTP servers creates an entry in the event log. For more information on
ensuring that AMP servers have the correct time, please see http://support.ntp.org/bin/view/Servers/
NTPPoolServers.
You can set the clock on a controller manually or by configuring the controller to use a Network Time Protocol
(NTP) server to synchronize its system clock with a central time source.
Manually Setting the Clock on a Controller
You can use either the WebUI or CLI to manually set the time on the controller’s clock.
1. Navigate to the Configuration > Management > Clock page.
2. Under Controller Date/Time, set the date and time for the clock.
3. Under Time Zone, enter the name of the time zone and the offset from Greenwich Mean Time (GMT).
4. To adjust the clock for daylight savings time, click Enabled under Summer Time. Additional fields appear
that allow you to set the offset from UTC, and the start and end recurrences.
5. Click Apply.
Enabling Support for Channel Utilization & Statistics
In order to enable support for channel utilization statistics, you must have the following:
 Dell PowerConnect W-AirWave 7.2 or later
 ArubaOS 6.0.1 or later
 Access points - Dell PowerConnect W-AP105, Dell PowerConnect W-AP92, Dell PowerConnect W-AP93,
Dell PowerConnect W-AP125, Dell PowerConnect W-AP124, Dell PowerConnect W-AP134
 Controllers - Dell PowerConnect W-Series 6xx, 3xxx, or 6000
NOTE: Specifying NTP servers is optional. NTP servers synchronize the time on the AMP server, not on individual access points.
Table 3 AMP Setup > Network > Secondary Network Fields and Default Values
Setting Default Description
Primary ntp1.yourdomain.com Sets the IP address or DNS name for the primary NTP server.
Secondary ntp2.yourdomain.com Sets the IP address or DNS name for the secondary NTP server.
NOTE: AOS 6.0.1 can report RF utilization metrics, while AOS 6.1 is necessary to also obtain classified interferer information.
