Setting Up Recommended Timeout and Retries
To set recommended timeout and retries settings, follow these steps:
1. In the Device Setup > Communication page, locate the SNMP Setting section.
2. Change SNMP Timeout setting to a value or either 3, 4, or 5. This is the number of seconds that the AirWave
will wait for a response from a device after sending an SNMP request, so a smaller number is more ideal.
3. Change SNMP Retries to 10. This value represents the number of times AirWave tries to poll a device when it
does not receive a response within the SNMP Timeout Period or the Group’s Missed SNMP Poll Threshold
setting (1-100).
NOTE: Al though the upper limit for this value is 40, some SNMP libraries still have a hard limit of 20 retries. In these cases, any retry
value that is set above 20 will still stop at 20.

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 AirWave and your network reference NTP server. NTP servers
synchronize with external reference time sources, such as satellites, radios, or modems.
NOTE: Specifyi ng NTP servers is optional. NTP servers synchronize the time on the AirWave server, not on indivi dual access points.
To disable NTP services, clear both the Primary and Secondary NTP server fields. Any problem related to
communication between AirWave and the NTP servers creates an entry in the event log. For more information on
ensuring that AirWave servers have the correct time, please see
http://support.ntp.org/bin/view/Servers/NTPPoolServers.
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.

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.
