Layer 2 Switch is a switching device that is chosen to bring effective connection in the network system of businesses and organizations. But many people also ask the question of whether Layer 2 Switch can divide VLAN? In the article below, DNG Corp will help you answer this question.<\/div>\n

What is Layer 2 Switch?<\/strong><\/h2>\n
Layer 2 Switch<\/a> is a technical term for a switching device that helps forward data packets in the LAN system – local area network. This device operates at layer 2, the data link layer of the TCP\/IP model.<\/div>\n
<\/div>\n
In the network system, L2 Switch will use MAC address to determine the path through the frames – where the data will be forwarded to perform the task of transmitting information between adjacent network nodes in a local area network or a wide area network.<\/div>\n
<\/div>\n
Layer 2 Switch device is the top choice of businesses used for network systems in offices or branches using Switch Access network infrastructure in LAN.<\/div>\n

What does L2 Switch mean?<\/em><\/p>\n

Features of Layer 2 Switch<\/strong><\/h2>\n
Layer 2 Switch is a type of Switch that possesses the most useful features needed for connecting and transmitting signals of the network system effectively. Let’s learn about these features of the product with DNG Corp.<\/div>\n
<\/div>\n
L2 Switch is responsible for switching based on the 2nd link layer – the OSI data layer. At the same time, they will use MAC addresses, from which the direction of the data packet can be determined more accurately.<\/div>\n
<\/div>\n
In addition, when data is transmitted, L2 Switch also allows users to check errors on each transmission and reception frame.<\/div>\n
<\/div>\n
In addition, the device also has the ability to automatically search for MAC addresses through the method of copying the address at each receiving frame and then maintaining that MAC address in the forwarding tables.<\/div>\n

Comparing Layer 2 Switch with Layer 3 Switch<\/strong><\/h2>\n
Layer 2 Switch and Layer 3 Switch are both important switching devices in the network system. But these two types of devices will also have differences.<\/div>\n
<\/div>\n
The biggest difference between the two types of Layer 3 and Layer 2 Switches is the routing method. L2 Switches can only route the same type of VLAN, while Layer 3 can route between VLANs. In addition, Layer 3 Switches have more improvements than Layer 2, so they can transmit data faster, ensuring more security, but in return, they will cost much more.<\/div>\n

\"Switch<\/p>\n

Layer 3 and Layer 2 switches have differences in routing methods.<\/em><\/p>\n

During use, businesses will use both Layer 3 and 2 Switches to create the most comprehensive network system.<\/div>\n

Can Layer 2 Switches divide VLANs?<\/strong><\/h2>\n
VLAN is known as the name for virtual LANs, used to create independent LANs logically on the same physical infrastructure. So can Layer 2 Switches divide VLANs? The answer to this question is yes, because one of the features of L2 Switches is dividing VLANs.<\/div>\n
<\/div>\n
However, we can only divide VLANs when using Layer 2 Managed Switches. With Layer 2 Unmanaged Switches, we cannot divide VLANs, but instead will need additional supporting Switch devices.<\/div>\n

Can Layer 2 switches share VLANs?<\/em><\/p>\n

Applications of Layer 3 and Layer 2 Switches<\/strong><\/h2>\n
Above, we have known whether Layer 2 Switches can divide VLANs or not?. Next, we will learn about the applications of these two types. In fact, these two types of Switches will be applied differently because they have different advantages and disadvantages.<\/div>\n

Advantages and disadvantages of L2 Switch<\/strong><\/h3>\n
Here are some advantages and disadvantages of L2 Switch:<\/div>\n
Advantages:<\/strong><\/div>\n
    \n
  • Helps the system forward packets based on a unique MAC at each terminal.<\/li>\n
  • Easy to retrieve information with fast transmission speed.<\/li>\n
  • Simple deployment, cost-effective.<\/li>\n
  • No time-consuming setup and management.<\/li>\n
  • Improved security with low latency.<\/li>\n
  • Provides flow accounting capabilities.<\/li>\n<\/ul>\n
    Disadvantages:<\/strong><\/div>\n
      \n
    • The packet forwarding function of L2 Switch is performed traditionally, and other advanced features cannot be applied.<\/li>\n
    • Does not support routing capabilities for packets based on IP addresses.<\/li>\n
    • Does not guarantee data transmission speed when users use Voice over IP.<\/li>\n<\/ul>\n

      Advantages and disadvantages of layer 3 switches<\/strong><\/h3>\n
      Some advantages and disadvantages of L3 Switch:<\/div>\n
      <\/div>\n
      Advantages:<\/strong><\/div>\n
        \n
      • Accurately determine the path to the destination network by using logical addresses.<\/li>\n
      • Ability to intelligently forward data packets.<\/li>\n
      • Allow users to turn on the router to quickly connect to different subnets in the network system.<\/li>\n
      • Enhanced security control helps to minimize unauthorized settings.<\/li>\n
      • Provides the ability to divide a network into multiple VLANs.<\/li>\n
      • Ensures data is transmitted as quickly as possible with minimal delay.<\/li>\n<\/ul>\n
        <\/div>\n
        Disadvantages:<\/strong><\/div>\n
          \n
        • To be able to switch at layer 3, it is necessary to use additional power and processing memory.<\/li>\n
        • More expensive than L2 Switch.<\/li>\n
        • Requires setup and management.<\/li>\n
