This article introduces the optimal performance of a vswitch in VLAN application configuration. The content of this article is as follows: filtering service function, Layer 2 network layer switch, Layer 3 network layer switch, data frame inbound, VLAN tag, below are some examples of different forms of switch VLAN applications. Filter service features: The filter

There are four ways to divide VLANs: 1. VLAN division by port Many VLAN manufacturers use the ports of vswitches to divide VLAN members. The configured ports are all in the same broadcast domain. For example, Ports 1, 2, 3, 4, and 5 of A vswitch are defined as virtual network AAA. Ports 6, 7, and 8 of the same vswitch form the virtual network BBB. In this way, c

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

. * Vro The vro is located at the network layer, which can isolate conflicting domains and broadcast domains. Each subnet (subnet) belongs to a broadcast domain. Broadcast cannot be sent between different subnets. Therefore, you must use a router (or a layer-3 Switch with routing functions) to control broadcast ). After a vro is used, the network Interface (LAN Interface) on the vro can be used to separate broadcast domains. Generally, vrouters and vswitches are used to segment the LAN into a la

Recently, I have participated in many discussion and evaluation activities on hospital network solutions. Almost all hospital solutions use VLAN technology, however, I found that VLAN design in most solutions has a common and fatal defect, that is, the core of VLAN spanning network. This article will talk about your views on this issue for your reference.

Port-based VLAN Division is the simplest and most effective VLAN division method. It defines VLAN members based on LAN switch ports. 1. Port-based VLAN Port-based VLAN Division is the simplest and most effective VLAN division meth

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

With the popularization of Switch Applications, VLAN technology is also widely used. As we all know, VLAN technology is mainly used to combine computers distributed in different geographic locations into a logical network as needed, while VLAN division can narrow the broadcast domain, to improve the network transmission speed, because computers in different VLANs

A vswitch is not designed as a security device, but is still designed to improve network performance. If you want to add a vswitch to the security mechanism, make sure that you configure the vswitch correctly, second, the switch manufacturer must fully understand and fully implement the basic standards of the switch software. If you have strict requirements on network security and do not use shared switches, you should use dedicated switches to Ensure network security. If a vswitch must be share

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.
