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.
You specify the timezone in terms of the offset from UTC (either plus or minus). For
example, to set the timezone for a GigaVUE TA Series node in the United States for
Pacific Standard Timezone, you would use the following command:
(config) # clock timezone America North United_States Pacific
Once you’ve finished configuring NTP options, use the show ntp command to
check the status of clock synchronization (

).

Enabling the Web Server
GigaVUE-FM is Gigamon’s Web-based management interface for the GigaVUE-OS,
including the GigaVUE TA Series TA
Series nodes. You can use GigaVUE-FM for many
system configuration, management, and operations tasks.
