Network Configuration

4.1.3.1

Host Name/Domain Name

Without a host name configuration, the controller is assigned a default name
which includes the last three values of the controller's MAC address, e.g.,
"PFCx00-A1A2A3." This name is valid for as long as a host name was not
configured, or host name was not supplied to the controller via DHCP (for
configuration of the controller see Section "Startup" > "Configuring"). When the
host name is set, a host name supplied by a DHCP response is immediately
active and displaces the configured or default host name. If there are multiple
network interfaces with DHCP, the last received host name is valid. If only the
configured name is to be valid, the network administrator must adjust the
configuration of the active DHCP server so that no host names are transferred in
the DHCP response.
The default host name or the configured name is active again if the network
interfaces are set to static IP addresses or if a host name is not received via the
DHCP response.
A similar mechanism is used for a domain name as for the host name. The
difference is that a default domain name is not set. As long as a domain name is
not configured or supplied by DHCP, the domain name is empty.
4.1.4

Routing

As part of the TCP/IP configuration, the controller allows you to configure static
routes, IP masquerading and port forwarding. Default gateways are configured
via static routes, since default gateways are a special case of static routes.
A network station transmits to a gateway all network data packets for systems
outside of its local network. This gateway is responsible for the appropriate
routing of the data packets so that they reach the target system. To allow access
to different target systems, it may be necessary to configure multiple gateways.
This is configured by adding routing entries.
A routing entry consists of the following information:
•
Destination address,
•
Destination mask,
•
Gateway address,
•
Gateway metric.
On the basis of the target system configuration, consisting of the destination
address and destination mask, a decision is made about which gateway a
network data packet should be forwarded to. The target system can be specified
through an individual IP address or an IP address range. For a network data
packet to forward, the routing entry with the most specific destination address
