A typical LAN refers to a core switch with a three-layer switching function to connect several branch switches (not necessarily three-layer switching capabilities). We assume that the core switch name is: COM, branch switches are: par1, PAR2, PAR3, respectively, through the port 1 Ray module with the core switch, and assume the VLAN name is counter, market, managing ...

In a network topology with two switches, can the same VLAN communicate? The answer is yes !!The Chinese meaning of trunk itself is: trunk, and trunk? In other words, it can carry something. It also plays a bearing role in the network, and it can carry multiple VLANs, enables communication between the same VLAN of different switching devices. As you can see, trunk also has its own structure. Since trunk is a

In the enterprise, to realize that all employees can communicate with the Internet, everyone using a public address is very unrealistic. Generally, the enterprise has 1 or several public network address, and the enterprise has dozens of, hundreds of employees. How do you want all employees to use the only few public network addresses to communicate with the Internet? Use NAT Technology!In the enterprise, there will be a number of departments, such as finance Department, technical department, eng

1. Background
Generally implement VLAN communication, or use a three-tier switch, or a single arm routing, both of which are very expensive, so when there is the need for VLAN communication, and the data volume of the VLAN communication is not very large, with 50 of Soho route to build a network is very affordable.
My original demand is this:With an n-port two-la
To address the limitations of traditional VLANs and ensure the security of network communication to a greater extent, many VLAN extension technologies have emerged in recent years, this article mainly introduces PVLAN, SuperVLAN, SVLAN and other typical extended VLAN technologies. 1 PVLAN Technology (Private VLAN) PVLAN divides
Principle 1: VLAN Based on ports-physical ports on VLAN switches and internal PVC (permanent virtual circuit) ports. Advantage: it is easy to define VLAN members. You only need to define all ports as corresponding VLAN groups. Disadvantage: if a user leaves the original port to a port of a new switch, it must be redefi

VLAN, as a virtual LAN technology, plays an important role in switch networking management and cloud computing platform network services, especially in the current Virtual Switching OVS, VLAN applications are more flexible and important. For the basic usage of
VLAN Implementation Mechanism After understanding why VLAN is needed, let's take a look at how a vswitch uses VLAN to separate broadcast domains.First, on a L2 Switch without any VLAN, any broadcast frame will be forwarded to all other ports except the acceptor port Flooding ).
