Setting Time Manually
The easiest way to set the GigaVUE TA Series node’s time is manually with the
clock set
command. For example:
(config) # clock set 05:18:38 2011/05/24
N
OTE
:
Even if you are using NTP/SNTP, It is a good idea to configure time
manually as well. The GigaVUE TA Series node will automatically fall back to the
manual time setting if it is unable to synchronize with the specified time server.
The
show ntp
will show the current state of the NTP server in use; the
show clock
command shows the current GigaVUE TA Series node’s time.
Performing One-Time NTP Server Synchronization
You can perform a one-time synchronization with an NTP server using the
ntpdate
command. For example:
(config) # ntpdate time.nist.gov
Note that this method does not provide updates to correct clock drift over time. It is
generally preferable to use persistent NTP synchronization with the
ntp
commands.
Using NTP Time Server for System Clock Synchronization
The GigaVUE TA Series nodes can optionally use one or more NTP servers for its time
setting. Use the following procedure to add an NTP server to the GigaVUE TA Series
node’s list and enable the use of NTP.
1. Specify the address of the time server. For example, if the time server is on
192.168.1.10, you would use the following command:
(config) # ntp server 192.168.1.10
N
OTE
:
There are many public NTP servers available on the Internet.
2. Turn on NTP with the following command:
(config) # ntp enable
3. The GigaVUE TA Series node connects to the specified NTP server and synchronizes
to its time.
4. NTP reports times in UTC. Because of this, It is a good idea to specify the GigaVUE
TA Series node’s timezone so that UTC can be converted to the local timezone.
