Client and Server
Parameters Meaning
Server Enables/disables the NTP client and the NTP server on the device.
Possible values:
"On"
The NTP client and the NTP server are enabled.
The NTP client obtains the time information from one or more NTP
servers in the network. The NTP server distributes the time
information to the NTP clients in the subordinate network segment.
"Off" (default setting)
The NTP client and the NTP server are disabled.
Note: If you enable the NTP client and the NTP server, the device disables
the function in the "Client" field in the "Client only" frame.
Mode Specifies in which mode the NTP server works.
Possible values:
client-server
(default setting)
With this setting, the device obtains the time information from NTP
servers in the network and distributes it to NTP clients in the
subordinate network segment.
– The NTP client takes the time information from the unicast
responses of the servers that are indicated as active in the
Time >
NTP
> Server
dialog.
– The NTP server distributes the time information via unicast to the
requesting clients.
symmetric
With this setting you integrate the device in a cluster of redundant NTP
servers. The device synchronizes the time information with the other
NTP servers in the cluster at intervals of 64 seconds.
In the
Time > NTP > Server
dialog, indicate the NTP servers
participating in the cluster as active.
Specify a uniform value for the stratum for the NTP servers
participating in the cluster.
Stratum Specifies the hierarchical distance of the device to the referent time
source.
Possible values:
1..16
(default setting:
12
)
Example: devices of the first level (Stratum
1
) synchronize themselves
directly with the reference time source and make the time information
available to the clients of the second level (Stratum
2
).
The device evaluates this value under the following circumstances:
The NTP server on the device is working in
symmetric
mode.
or
The device is using the local system clock as the time source. See the
"Time Source" field in the
Time > Basic Settings
dialog.
