D-Link DES-1228/ME Reference Manual page 6

Starting at the command line prompt, enter the command config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where
the x's represent the IP address to be assigned to the IP interface named System and the y's represent the corresponding subnet
mask.
Alternatively, users can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x's represent the IP address to be
assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.
The IP interface named System on the Switch can be assigned an IP address and subnet mask which can then be used to connect a
management station to the Switch's Telnet or Web-based management agent.
DES-1228/ME:5#config ipif System ipaddress 10.73.21.11/8
Command: config ipif System ipaddress 10.73.21.11/8
Success.
DES-1228/ME:5#
In the above example, the Switch was assigned an IP address of 10.73.21.11 with a subnet mask of 255.0.0.0. The system message
Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet,
SNMP MIB browser and the CLI or via the Web-based management agent using the above IP address to connect to the Switch.
