Note: You may consider binding a secondary IP address to one NIC that matches the new network segment for this configuration ahead of actual firewall configuration.

Step 1: Open a web browser and type the IP address of the D-Link firewall into the address bar (default is 192.168.1.1). Press Enter.

Step 2: The default username is admin (all lower case) and the password is admin (all lower case). Click on OK.

Step 3: Click on the plus sign next to Objects, select Address Book, and then select Interface Addresses.

Step 4: Click on the lan_ip folder and edit the IP address as desired and then click OK.

Note: You will also need to change the lan subnet and DHCP client pool (Only if a DHCP server is enabled on the firewall) to reflect the new IP subnet.

Step 5: Click on the Configuration tab and select Save and Activate from the drop-down menu. Click on OK to save and activate your changes.

Note: The new LAN IP address will have to accessed within the validation timeout period. The default value is 30 seconds. To change the timeout period, click on the plus sign next to System, select Remote Management, and then select Advanced Settings. Change the Validation Timeout, and click OK.

After you perform the physical hardware installation, you need to connect the D-Link Unified Switch to the network. The default IP address of the switch is 10.90.90.90/8, and DHCP is disabled by default. If you want to enable DHCP on the switch or assign a different static IP address, you must connect to the DWS-3026 switch and change the default settings.

You can connect to the switch through Telnet or a Web browser from a host on the 10.0.0.0/8 network, or you can connect to the switch through the console port (RS-232 DCE). After you connect to the switch, you can provide network information or enable the DHCP client. To connect to the DWS-3026 switch from a host on the 10.0.0.0 network, enter the default IP address of the switch (10.90.90.90) into the address field of a Web browser or a Telnet client.

To connect to the console port and provide network information, use the following steps:

1. Using a null-modem cable, connect a VT100/ANSI terminal or a workstation to the console (serial) port.

If you attached a PC, Apple, or UNIX workstation, start a terminal-emulation program,such as HyperTerminal or TeraTerm.

2. Configure the terminal-emulation program to use the following settings:

- Baud rate: 115,000 bps
- Data bits: 8
- Parity: none
- Stop bit: 1
- Flow control: none

3. Press the return key, and the User: prompt appears.

Enter admin as the user name. There is no default password. Press ENTER at the password prompt if you did not change the default password. After a successful login, the screen shows the (switch-prompt)> prompt.

4. At the (switch-prompt)> prompt, enter enable to enter the Privileged EXEC command mode. There is no default password to enter Privileged EXEC mode. Press ENTER at the password prompt if you did not change the default password.

5. Configure the network information.

- To use a DHCP server to obtain the IP address, subnet mask, and default gateway information, enter network protocol dhcp.
- To use a BootP server to obtain the IP address, subnet mask, and default gateway information, enter network protocol bootp.
- To manually configure the IP address, subnet mask, and default gateway, enter network parms [], for example:

network parms 192.168.2.23 255.255.255.0 192.168.2.1 The default gateway is an optional parameter, so you do not need to enter an address to execute the command.

To view the network information, enter show network.

6. To save these changes so they are retained during a D-Link switch reset, enter the following command:

write

Once the D-Link Unified Switch is connected to the network, you can use the IP address for remote access to the DWS-3026 switch by using a Web browser or through Telnet or SSH.

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 10.90.90.90. 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 10.53.13.83 with a subnet mask of 255.0.0.0. The user may also use the CIDR form to set the address (10.53.13.83/8).

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.

Please Login the D-Link DGS-3612G Switch,default IP is 10.90.90.90.

The IP Address may initially be set using the console interface prior to connecting to it through the Ethernet. If the Switch IP address has not yet been changed, read the introduction of the DGS-3600 Series CLI Refence Guide or return to Section 4 of this manual for more information.

To view the Switch’s current IP settings, click Administration > IP Address, as shown below:

To manually assign the Switch’s IP address, subnet mask, and default gateway address:

1. Select Manual from the Get IP From drop-down menu.

2. Enter the appropriate IP Address and Subnet Mask.

3. If you will manage the Switch from the subnet on which it is installed, you can leave the default address (0.0.0.0) in this field.

4. If no VLANs have been previously configured on the Switch, you can use the default VLAN Name. The default VLAN contains all of the Switch ports as members. If VLANs have been previously configured on the Switch, you will need to enter the VLAN Name of the VLAN that contains the port connected to the management station that will access the Switch. The Switch will allow management access from stations with the same VID listed here.

NOTE: The Switch’s factory default IP address is 10.90.90.90 with a subnet mask of 255.0.0.0 and a default gateway of 0.0.0.0.

To use the BOOTP or DHCP protocols to assign the Switch an IP address, subnet mask, and default gateway address:
Use the Get IP From pull-down menu to choose from BOOTP or DHCP. This selects how the Switch will be assigned an IP address.

IP MTU Settings

The IP MTU Settings window is used to configure the IP layer MTU settings on the Switch. The MTU is the largest size of IP datagram which may be transferred using a specific data link connection. The MTU value is a design parameter of a LAN and is a mutually agreed value (i.e. both ends of a link agree to use the same specific value) for most WAN links. The size of MTU may vary greatly between different links. Instead of making routers fragment packets, an end system could try to find out the largest IP packet that may be sent to a specific destination.

When one IP host wants to transmit an IP datagram, it is usually preferable that the datagrams be of the largest size that does not require fragmentation anywhere along the path from the source to the destination. The path MTU is equal to the minimum MTUs of each hop in the path.

To configure the Switch’s current IP MTU settings, click Administration > IP MTU Settings, as shown below:

IP Interface Name:Specifies the name of the IP Interface to be used.

IP MTU (512-1712):The user can configure each interface’s IP MTU. If the user does not designate an MTU value when creating an interface, the default value of 1500 will be used.
