New Switch (D-Link)

D-Link switches are highly popular in SMB and edge environments. They do not use proprietary software like WinBox, and many models rely entirely on web management.

1. Initial Access

1. A factory default D-Link switch typically defaults to 10.90.90.90 (Check the sticker on the bottom of your specific model).
2. Connect your PC to any port on the switch.
3. Configure your PC with a static IP address in the same subnet, such as 10.90.90.100 / 24.
4. Open a web browser to http://10.90.90.90.
5. Log in with the default credentials.

2. Setting the Management IP

1. Navigate to System → System Settings → IPv4 Interface.
2. Select the System interface.
3. Choose Static (instead of DHCP).
4. Enter your intended network Management IP and Subnet Mask.
5. Enter your Default Gateway (the IP of your router).
6. Click Apply.

3. Creating VLANs (802.1Q)

1. Navigate to L2 Features → VLAN → 802.1Q VLAN.
2. By default, all ports are Untagged members of VLAN 1.
3. Click Add to create a new VLAN.
4. Enter the VID (VLAN ID, e.g., 10) and VLAN Name (e.g., Sales).

4. Assigning Ports (Tagged vs Untagged)

In the same 802.1Q VLAN menu:

1. Click the port numbers to cycle through their state:
   • U (Untagged): Set this for Access ports (connecting to PCs).
   • T (Tagged): Set this for Trunk ports (uplinks to routers).
   • Blank: Set this for ports that should not receive this VLAN’s traffic.
2. Click Apply.

Important PVID Step: For any port you set as U (Untagged), you must also change its PVID (Port VLAN ID)!

1. Navigate to L2 Features → VLAN → 802.1Q VLAN PVID Settings.
2. Select the port(s).
3. Enter the PVID matching the VLAN you just assigned (e.g., 10).
4. Click Apply.

5. Save the Configuration

1. Click the Save menu at the top of the interface.
2. Select Save Configuration.
3. Confirm to save the configuration to NVRAM. If you skip this, a power outage will revert your switch to factory defaults!
