The four numbers of an IP address separated by periods are interpreted as a bit pattern. If a
one is set at a bit position within the subnet mask, this means that only devices with an IP
address that matches the IP address of the SCALANCE W-700 at this bit position can
communicate with the SCALANCE W-700 management agent.
Example
Let us assume that the IP address of the SCALANCE W-700 is set to 192.168.147.189 and
the subnet mask is set to 255.255.255.0. The bit pattern for 255 is 1111 1111. This means
that the bit pattern of the first number of the IP address of a communication partner must
match the bit pattern of the SCALANCE W-700 exactly at this point. The same applies to the
second and third parts of the IP address. The IP address of a communication partner must
therefore start with 192.168.147. The bit pattern of 0 is 0000 0000. This means that the bit
pattern of the last part of the IP address of the partner device does not need to match the
address of the SCALANCE W-700 at any point; in other words, it can be any number.
5.4.2
System name
Description
The system name identifies a network node but means more to the user than the IP address.
System name
input box
In this box, you enter the system name for your SCALANCE W-700. This parameter
corresponds to the "sysName" SNMP parameter. The system name can be up to a
maximum of 255 characters long. If you also want to use this parameter for WDS or
redundancy, the maximum length is 30 characters.
