D-Link IP Address Assignment(D-Link DES-3800 Series)

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other
TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is You can change the default
Switch IP address to meet the specification of your networking address scheme.


The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found by entering the command “show switch” into the command line interface, as shown below.


The Switch’s MAC address can also be found from the Web management program on the Switch Information (Basic Settings)
window on the Configuration menu.

The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:
Starting at the command line prompt, enter the commands.

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, and then be used to connect a management station to the Switch’s Telnet or Web-based management agent.


In the above example, the Switch was assigned an IP address of with a subnet mask of The user may also use the CIDR form to set the address (

The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet and the CLI or via the Web-based management.
