Wireless Array
Configuring the Wireless Array 185
Time Settings (NTP)
This window allows you to manage the Array’s time settings, including
synchronizing the Array’s clock with a universal clock from an NTP (Network
Time Protocol) server. We recommend that you use NTP for proper operation of
SNMP in XMS (the Xirrus Management System), since a lack of synchronization
will cause errors to be detected. Synchronizing the Array’s clock with an NTP
server also ensures that Syslog time-stamping is maintained across all units.
It is possible to use authentication with NTP to ensure that you are receiving
synchronization from a known source. For example, the instructions for
requesting a key for the NIST Authenticated NTP server are available at 
http://www.nist.gov/pml/div688/grp00/upload/ntp_instructions.pdf.
The Array allows you to enter optional authentication information.
