Upgrade Instructions

D-Link Smart Switches support firmware upgrade via TFTP server. You can download the firmware from D-Link web site http://tsd.dlink.com.tw, and copy the downloaded firmware to the TFTP server folder. Please make sure that the TFTP server is accessible from the switch via networks.

Upgrade using CLI (via Telnet)

  1. Make sure the network connection between the switch and PC is active.
  2. Use software that supports telnet, for example, HyperTerminal or Telnet command in Microsoft Windows, to connect to the switch. If you are using Telnet command, type the command followed by the switch IP address, e.g. telnet 10.90.90.90.
  3. The logon prompt will appear. The switch will prompt the user to enter his/her username and password. It should be noted that upon the initial connection, both the default user name and password are admin.

To upgrade the switch firmware, execute the following commands:

CommandFunction
copy tftp://location/filename flash: {Image1|Image2}Download firmware file from the TFTP server to the switch.
boot image {Image1|Image2}Change the boot up image file.
show bootDisplay the information of current boot image and configuration.
rebootReboot the switch.

Example: DGS-1250-28X CLI Upgrade

Command: copy tftp: //10.90.90.99/DGS1250/DGS-1250_Run_1_00_039.had flash: Image1

Upgrade using Web-UI

  1. Connect a workstation installed with Java SE runtime environment to any switch port of the device.
  2. Open the web browser from the workstation and enter the IP address of the switch. The switch's default IP address is 10.90.90.90.
  3. Enter administrator's password when prompted. The password is admin by default.
  4. Two methods can be selected to update switch's firmware or configuration file:
    • A. Go to Tools > Firmware Upgrade & Backup > Firmware Upgrade from HTTP from the banner.
    • B. Go to Tools > Firmware Upgrade & Backup > Firmware Upgrade from TFTP from the banner.

Known Issues

Firmware VersionIssuesWorkaround
V1.00.039N/A
V1.00.004N/A
V2.01.006
  1. [DBG19040443] Deleting specific VLANs will show success but it does not exist in VLAN entries.
  2. [DBG19040523] There is no warning message for un-existed time profile on Power Saving page.

Chip Limitation:

  1. In the current design, NDP packets(ICMPv6 type 133~137) cannot be deny the HW forward packets by user ACL. It is chip limitation for DGS-1250.
  2. The destination port numbers 5426 and 5427 are used for CAPWAP data and control packets in the DGS-1250-28X/28XMP chip. If the switch checks that the header is invalid, the default action of both packets will be dropped.
  3. Dynamic ARP entries cannot be kept when the related L2 entry age-out.
  4. If aging time of "ARP" is greater than aging time of "MAC address", when MAC address is aged out, the corresponding ARP entries will be aged out, too.
