7.3.2.1.17 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.
7.3.2.1.18 IPv6 Subnet Prefix Lengh
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.
7.3.2.1.19 VLAN (Activation Key necessary)
A VLAN (Virtual Local Area Network) is a logical sub-network within a network switch or a
whole physical network. VLANs are used to separate the logical network infrastructure from
the physical wiring, thus to virtualize the Local Area Network. The technology of VLAN is
standardized by IEEE Standard 802.1q. Network applications like Time Server 8030NTS/GPS,
implementing the standard IEEE 802.1q, are able to allocate individual network interfaces to
specific VLANs. To transfer data packets of several VLANs via a single network interface the
data packets are marked with a related VLAN ID. This method is called VLAN-Tagging. The
network application at the other end of the line (e.g. network switch, router etc.) can allocate
the data packet to the correct VLAN by checking the marking / tag.
WebGUI with activated VLAN
To be able to configure VLANs the activation status must be set to "enabled" first. Afterwards
up to 32 different VLANs per network interface can be configured by clicking the button "Add".
An explicit VLAN ID must be configured for each VLAN interface.
The boxes "Label" and "Remark" can be filled out with a designation or a comment to easily
keep the configured VLANs apart.
Determination of the IP-address for the configured VLAN interface can either be done
automatically via DHCP or by filling out the boxes "IP-Address" and "Network Mask".
To ensure the correct function the network appliance must be connected
with Time Server 8030NTS/GPS via the network interface. Furthermore it
must be ensured that the network appliance is accurately configured with
the same VLANs.
VLAN ID one (1) and two (2) are reserved and are therefore not permitted!
