Vlan and switch port mode Access, Hybrid, Trunk

1 VLAN description the Chinese name of a VLAN (VirtualLocalAreaNetwork) is a virtual LAN. VLAN is a new data exchange technology that logically divides LAN devices into network segments to implement virtual working groups. This emerging technology is mainly used in vswitches and routers, but mainstream applications are still in vswitches. But not all vswitches 1.

Technical analysis: VLAN access Link

Vswitch Port Vswitch ports can be divided into the following two types:Access Link)Aggregation Link Trunk Link)Next, let's learn the characteristics of these two different ports in sequence. First, we will learn "Access Links ".Access Link The access link refers to the port "only belongs to one VLAN and forwards data frames to this VLAN. In most cases, the access link is connected to a client.Generally, the

Use VLAN with caution

Currently, a large-scale LAN or man can be constructed in two structures: a standard TCP/IP structure based on a distributed Router or an Internet structure; the other is a VLAN-based fully switched network structure. A VLAN is a virtual network segment. Recently, more and more topics have been related to VLANs. Many people have expressed great interest in VLAN u

Layer 3 Switch construction enterprise VLAN

The emergence of Virtual lan vlan breaks the many inherent concepts of traditional networks, making the network structure flexible, convenient, and free to do as you like. VLAN divides user logic into working groups with relatively independent functions based on functions, applications, and other factors without considering users' physical locations, each user host is connected to a switch port supporting

Three-layer Switch link aggregation (VTP + VLAN + STP)

Two switch configuration modes to configure Port-based VLAN as an example

client, the switch can be configured completely. If you think that the management port is inconvenient, you can set the management IP address of the switch, turn on telnet or Http/https connection, and manage it through the LAN connection switch. The configuration command for a switch has a hierarchy and is a command tree that allows you to drill down through the command layer to configure fine items. Following any command with a question mark, you can get hints and instructions for the sub

How to configure VLAN partitioning on a switch

We know that the traditional LAN Ethernet uses a carrier-monitored multi-channel access (CSMA/CD) method with conflicting detection. In CSMA/CD networks, nodes can use the network at any time they have data to send. Before the node transmits data, it "listens" to see if the network is busy. If not, the node begins to transfer the data. If the network is in use, the node waits. If two nodes are listening, without hearing anything, and starting to use the line at the same time, there will be a con

VLAN Technology Entry

VLAN is short for Virtual Local Area Network. On the one hand, VLAN is built on the basis of LAN switches; on the other hand, VLAN is the soul of LAN. This is because VLAN users can easily move and quickly build a broadband network in the network without changing any hardware and communication lines. In this way, the n
