8.3.2.2.6 Operation Mode
The network device usually adjusts the data stream
and duplex mode to the device to which it is connected
(e.g. HUB, SWITCH) automatically. If the network de-
vice requires a certain speed or duplex mode, this can
be configured via the web interface. The value should
only be changed in special cases. The automatic set-
ting is normally used.
In individual cases an enabled "Auto negotiate" might lead to problems be-
tween the network components and the adjustment process fails.
In such cases it is recommended to set the network speed of the Time
Server 8030HEPTA/GPS
and
the connected network components manually
to the same value.
8.3.2.2.7 Maximum Transmission Unit (MTU)
The Maximum Transmission Unit describes the maximum size of a data packet of a protocol
of the network layer (layer 3 of OSI model), measured in octets which can be transferred into
the frame of a net of the security layer (layer 2 of OSI model) without fragmentation.
Time Server 8030HEPTA/GPS is going to be delivered with default setting 1356.
8.3.2.2.1 IPv6
The Time Server 8030HEPTA/GPS can also be operated in an IPv6 network.
To enable IPv6,
Use IPv6 Settings
must be set to
enable
.
IPv6 addresses are 128 bits long and they are recorded in eight 4-character hexadecimal
blocks. For example:
2001:0db8:0000:08d3:1319:8a2e:0370:7344
Leading zeroes in a 4-character hexadecimal block can be omitted. For the above example,
this results in the notation:
2001:db8:0:8d3:1319:8a2e:370:7344
In addition,
once
per IPv6 address a consecutive sequence of blocks containing all zeros may
be omitted. But this must be recorded with two consecutive colons. For the above example,
this gives the notation:
2001:db8::8d3:1319:8a2e:370:7344
Another example:
2001:0:0:0:1319:8a2e:0:7344
may be represented
as
2001::1319:8a2e:0:7344
or
2001:0:0:0:1319:8a2e::7344
8.3.2.2.2 DHCP-IPv6
If DHCP is to be used, this function is activated with
enabled
.
8.3.2.2.3
IPv6 Address
If DHCP is not used, enter the IPv6 address here. If the IPv6 address to be used is unknown,
it must be requested by the network administrator.
