Description
This string is used for the Siemens Industry-
specific OID
automationSystemIdent.automationFunctionTag.
If required, a function designation can be
specified here which can be called with an SNMP
client. This is for information purposes only.
Defines an additional DNS domain name (suffix
for DNS queries). This is of especial interest
when the DHCP server is switched off at the
X120 because this cannot set the "local" domain,
but it is required for some DNS queries (e.g. for
machine control panels).
Specifies up to three DNS servers that are to be
used by the DHCP server. This is of especial
interest when the DHCP server is switched off at
the X120 because this is also a DNS server or
determines DNS servers in the network.
Specifies whether the routing of packets from the
system network (X120) and/or service connection
X127 to the company network (X130) is active:
Enabled: Activates the routing for X120 and
•
X127
Disabled: Deactivates the routing for X120
•
and X127
X127: Activates only the routing from X127 to
•
the company network
X120: Activates only the routing from the
•
system network to the company network
Activates or deactivates the NAT routing of
packets from the service connection X127 to the
system network (X120).
Activates or deactivates the routing of packets
from the system network (X120) to the service
connection X127. This is normally prohibited by
the firewall.
Note that there is no NAT and the sender must
ensure that packets to the PG or service PC at
X127 with address 192.168.215.x actually reach
the NCU to which the device is connected.
Specifies which protocols are to be used in the
system network. DCP (Discovery and Basic
Configuration Protocol) and LLDP (Link Layer
Discovery Protocol) are available for selection.
The appropriate active protocol is also used for
the service connection X127 at the NCU.
