Q: Why does my Web Smart switch(DGS-1216T) always log me out when moving from page to page or link to link?

A: Please ensure that you are using Internet Explorer 6.0.x or higher when configuring D-Link Web Smart switches, as other browsers or earlier versions of IE may cause some minor problems. You will not be logged out of your switch when using Internet Explorer 6.0.x or higher.

Q: Why are my ping request slower when using D-Link Web SMART Switches?

A: Since the Web Smart switches are not as robust in features as fully managed switches, they have a slower CPU. Therefore, depending on what process Web Smart switch is currently running, the ping response time will be varied and longer.

Q: What is a Combo Port on an Ethernet Switch?

A: A Gigabit Ethernet Combo port is an Ethernet port and a Mini-GBIC port (also called SFP´s) that share the same switch fabric and port number. A Combo port is a way to provide different types of connectivity without taking up unused switch fabric. These Combo ports can also be labeled as tied, meaning two different physical ports that can only be used one at a time. A Gigabit Ethernet Combo port consists of one 1000Base-T Gigabit over Copper port (provided), and one Mini-GBIC port (empty port that requires Mini-GBIC module).

Q: Why can´t I share my Internet connection to multiple computers when using my D-Link switch or hub?

A: If you are connecting directly to a Cable or DSL modem, you will need a router to share your Internet connection or a computer using ICS (Internet Connection Sharing) or Proxy. Switches and hubs do not allow you to share a single IP address to multiple computers.

Another alternative is to contact your ISP and purchase extra IP addresses for each additional computer.

    Store-and-Forward switching will wait until the entire frame has arrived prior to forwarding it. This method stores the entire frame in memory. Once the frame is in memory, the switch checks the destination address, source address, and the CRC. If no errors are present, the frame is forwarded to the appropriate port. This process ensures that the destination network is not affected by corrupted or truncated frames.


    Cut-Through switching will begin forwarding the frame as soon as the destination address is identified. The difference between this and Store-and-Forward is that Store-and-Forward receives the whole frame before forwarding. Since frame errors cannot be detected by reading only the destination address, Cut-Through may impact network performance by forwarding corrupted or truncated frames. These bad frames can create broadcast storms wherein several devices on the network respond to the corrupted frames simultaneously.
