Upgrade Instructions:

D-Link Smart Switches support firmware upgrades via TFTP server. You can download the firmware from the D-Link website 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 the Telnet command, type the command followed by the switch IP address, eg. telnet 10.90.90.90.
  3. The login 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:

Command Function
copy tftp://location/filename flash: {Image1|Image2} Download the firmware file from the TFTP server to the switch.
Boot image {Image1|Image2} Change the bootup image file.
Show boot Display the information of the current boot image and configuration.
reboot Reboot the switch

Example: 
DGS-1250-28X:
Command: copy tftp: //10.90.90.99/DGS1250/DGS-1250_Run_1_00_039.had flash: Image1

 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.
