How do you divide vlan on the third floor

The three-tier switch is an advanced network device that allows routeing between different virtual local area networks (vlans). The division of vlan can help us better manage and control network traffic and improve network performance and safety。

If vlan is to be correctly divided, it is first necessary to understand the rationale behind the three-storey switch. The three-layer switch has multiple physical interfaces or ports, each of which can be connected to a particular subnet or vlan. By linking different ports to different vlans, the package is transmitted in such a way as to determine how to handle the package according to vlan, which belongs to the target address。

Here are some common ways to divide vlan:

Port-bPlease vlan: this is the simplest and most straightforward way. The administrator can manually configure which vlan belongs to each port and only allow communication between the same vlan。

Mac address -bCased vlan: using mac addresses as a basis for dividing vlan is also a common method. The administrator links a specified range of mac addresses to a particular vlan。

3. Ip address-bPlease vlan: it is also common to use ip addresses as a basis for dividing vlan. The administrator links a given range of ip addresses to a particular vlan。

4. Agreements-bCased vlan: this approach is based on applying the protocol type to classify the package and send it to the corresponding vla n associated with the protocol。

The above list only a few common methods, and in fact there are other more complex and flexible ways to divide vlan than using source or target ip address, subnet mask, tcp/udp port number, etc. At the end of the day, the method for dividing vla n shall be determined according to the physical needs and set-up to ensure that the network works smoothly and meets safety requirements。

In summary, the three-storey switcher achieves isolation and communication control between different subnets or logical tissues by various means. Rational division of vl an not only enhances the capacity and security, but also better organizes and regulates network traffic。
