1.5 Interface identifiers and addresses
SCALANCE S615 Command Line Interface

● MAC addresses
In the syntax of the Command Line Interface, a MAC address is represented as a
sequence of 6 bytes in hexadecimal format, in each case separated by a colon.
The syntax is then, for example aa:aa:aa:aa:aa:aa
● Multicast addresses
Layer 2 multicast addresses as used on this device use the notation of MAC addresses.
For permitted address ranges, check the rules or ask your network administrator.
IPv4 address
Range of values for IPv4 address
The IPv4 address consists of four decimal numbers with the range from 0 to 255, each
number separated by a period; example: 141.80.0.16
IPv4 address format - notation
An IPv4 address consists of 4 bytes. Each byte is represented in decimal, with a dot
separating it from the previous one.
XXX.XXX.XXX.XXX
XXX stands for a number between 0 and 255
The IPv4 address consists of two parts:
● The address of the (sub) network
● The address of the node (generally also called end node, host or network node)
Range of values for subnet mask
The subnet mask consists of four decimal numbers with the range from 0 to 255, each
number separated by a period; example: 255.255.0.0
The binary representation of the 4 subnet mask decimal numbers must contain a series of
consecutive 1s from the left and a series of consecutive 0s from the right.
The 1s specify the network number within the IPv4 address. The 0s specify the host address
within the IPv4 address.
Example:
Correct values:
255.255.0.0 D = 1111 1111.1111 1111.0000 0000.0000 0000 B
255.255.128.0 D = 1111 1111.1111 1111.1000 0000.0000 0000 B
255.254.0.0 D = 1111 1111.1111 1110.0000 0000.0000.0000 B
Incorrect value:
255.255.1.0 D = 1111 1111.1111 1111.0000 0001.0000 0000 B
