The IP addresses of the SNTP servers and the time offset can also be specified
automatically through DHCP. See
“DHCP Options” on page 63 .
The
set status {enable|disable}
command enables or disables the SNTP client.
To use this service, you must configure the IP address of at least one SNTP
server either manually or through DHCP. When the SNTP client is enabled, the
BelAir100SN’s clock is reset to use UTC.
The
show status
and the
show config
commands display whether the SNTP
process is running or not and the effective (actual) information used by the
SNTP client as well as the information stored by the BelAir100SN. Differences
may be caused by the setting of the
accept-dhcp-params
parameter. See “DHCP
Options” on page 63 .
Example 1
/protocol/sntp# set ip-address primary 10.1.1.2
Example 2
/protocol/sntp# set timeoffset -4 30
Example 3
/protocol/sntp# show status
SNTP process is running
Effective SNTP Timeoffset:
===========================
SNTP Timeoffset origin: SNTP schema
SNTP Timeoffset: -4:00
Effective SNTP server:
======================
SNTP Servers origin: SNTP schema
Active Server: Primary - 180.1.4.31
SNTP server Primary : 180.1.4.31
SNTP server Secondary: 0.0.0.0
GPS Coordinates
/system/set coordinates {latitude|longitude}
([degrees <-180,180>] [minutes <0,59>]
[seconds <0,59>] [milliseconds <0,999>])
/system/show coordinates
These commands allow you to manually specify the exact geographic location of
a BelAir unit. You can then use the Global Positioning System (GPS)
coordinates to locate a unit in the field.
Example
/system# set coordinates latitude degrees 76 minutes 55 seconds 54 milliseconds 53
/system# set coordinates longitude degrees -120 minutes 12 seconds 34 milliseconds 56
/system# show coordinates
