In individual cases an enabled "Auto negotiate" might lead to problems
between the network components and the adjustment process fails.
In such cases it is recommended to set the network speed of the Time Client
8029NTC
and the connected network components manually to the same
value.
5.3.3.2.7 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.
Network Time Client 8029NTC is going to be delivered with default setting 1356.
5.3.3.2.8 IPv6
The Network Time Client 8029NTC 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 zeroes
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
5.3.3.2.9 DHCP-IPv6
If DHCP should be used, this function is activated with enabled .
5.3.3.2.10 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.
5.3.3.2.11 IPv6 Subnet Prefix Length
If no DHCP is used, the length of the network address must be entered here. If the length of
the network address is not known, it must be requested by the network administrator.
