It uses the DWAPP (D-Link Wireless AP Protocol). It can cross a L2 or L3 network but must meet the following conditions:
1) No NAT between the wireless controller and the AP’s. However, a VPN can be used if the AP’s are across the internet
2) VLAN (L2) and routing (L3) must be configured between the controller and the AP’s
3) The following ports must be opened between the wireless controller and the AP’s (you will need to allow them in any filter or firewall between the switch and AP’s):
Between the controller and the AP’s:
  • TCP Port 57777, SSL encryption (for Firmware/Profile delivery/Heartbeat/Client session key sharing etc.)
  • UDP/Port 57775, 57776 (for Report and Statistics)
Between one controller and another controller (cluster group):
  • TCP/port 57777, SSL encryption (for Client data/AP data/RF status sharing within peer switches)
  • UDP/port 57775

Your D-Link switch has no built in DHCP server, meaning it does not have the capability to issue IP addresses. Please check your DHCP server to ensure that it is functioning properly. In most cases your router will act as your DHCP server.

If you are sure that your DHCP server is functioning properly then please test DHCP with other PCs connected to your switch. Your PC or network card may be the cause of your problem.

Class of Service (CoS) is a way of managing traffic in a network by grouping similar types of traffic for example: streaming video,voice,etc… and treating each type as a class with its own level of service priority.

Step 1: Open a web browser such as Internet Explorer or Netscape, and enter the IP address of the switch (Ex:192.168.20.223). Press Enter.

Step 2 Enter your username (admin) and your password (blank by default). Click Ok to access the Web Configuration.

Step 3: Click on the plus sign (+) next to QOS, then the plus sign (+) next to Class of Service. Select Interface Queue Configuration.

Step 4: Configure the following:

  • Slot/Port – Specifies all CoS configurable interfaces. The option Global represents the most recent global configuration settings.
    These may be overridden on a per-interface basis.
  • Queue ID – Specifies the queue ID.
  • Minimum Bandwidth – Specifies the minimum guaranteed bandwidth alloted to this queue. The value 0 means no guaranteed minimum.
    The total of individual minimum bandwidth values for all queues in the selected interface cannot exceed 100.
  • Scheduler Type – Specifies the type of scheduling used for this queue, it can only be either Strict or Weighted.
  • Queue Management Type – This is only used if the device supports independent settings per-queue, the default setting is Taildrop

    Step 5: Click Submit.
