TIP:
For enhanced security, consider using misspelled words, a combi-
nation of letters and numbers, and a combination of upper and
lower case letters. Also, the Network Name should be at least nine
characters long. This helps protect against sophisticated hackers
who may use a database of common words (for example, dictio-
nary attacks) to determine the Network Name.
•
SNTP Server
—Address of SNTP server (RFC 2030) from which
the transceiver will automatically get the time-of-day startup
time. Without an SNTP server, the date and time must be man-
ually set. An AP will try to get the time and date from the SNTP
server only if an IP address is configured. It will continue to
retry every minute until it succeeds.
A remote will get the time and date from the SNTP server, if an
IP address is configured. Otherwise it gets it from the AP at
authentication time. The transceivers use UTC (Universal Time
Constant) with a configurable time offset. [
0.0.0.0
]
•

local static IP address of the transceiver. Detailed explanations
