In this section we look at how to implement and configure the following VLAN networks in an experimental environmentConfigure VLANsEdit/etc/network/interfaces, configure eth0.10, Brvlan10, eth0.20, and Brvlan20.The following shows the modification of/etc/network/interfaces with Vmdiff.Restart host, ifconfig each network interfaceUse Brctl Show to view the configuration of the current Linux Bridge.

The Chinese name of a VLAN (Virtual Local Area Network) is "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. However, not all vswitches have this function. Only the layer-3 or above vswitches o

As we all know, VLANs exist for convenience of management and security. How to Create a Vlan? Let me configure a simple Vlan network for communication between VLANs and between non-VLANs! The parameters are as follows: Vlan3: 172.28.255.255.255.255.0 Vlan5: 172.28.15.0 255.255.255.0 Vlan1: 172.28.16.0 255.255.255.0 Vlan4: 172.28.14.0 255.255.255.0 R. 11.11.1 255.255.255.0R. 11.11.2 255.255.255.0 The network

Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on different ports on the same switch

The VTP password settings and Huawei switch vlan configuration experiment results show you how to configure the vlan of a Huawei switch. Many people may not understand the vlan configuration of a Huawei switch, VTP transparent mode, VTP password settings, and V1, v2 integrated application. It doesn't matter. After reading this article, you will certainly have a l

First, let's take a look at what tpid means? Frames in the 802.1Q document of VLAN protocol are embodied in the following data packets: Here, the blue position is the 802.1Q header, and the specific meaning of each item is: Tag protocol identifier(TAG protocol ide

First, we need to understand the origin of VLAN and why such a technology is generated. This starts with the data exchange in the computer network. At the very beginning, our network was in the wild age. How did we exchange data, that is, simple media sharing, and everyone was connected to a line, then send data to each other, which will inevitably lead to a problem. There is only one way for everyone to compete, and there will inevitably be no confli

I am eager for the first time to switch between vlan routing and nat addresses of Cisco switches. I am very energetic and have an undefeated spirit. I am ready to continue to answer questions during multiple rounds of interviews. My little brother squashed his eyes and took out the bottom of the press box: If my company has two Internet interfaces, A and B, respectively. The following vswitch divides multiple VLANs. One of the VLANs goes through the-l

frame, view the source address (host a) and add it to the MAC address table. However, the switch does not know which port the Host B is on (MAC Address table does not have the MAC address of Host B), so this frame is an unknown unicast frame. The swap opportunity floods this frame.1.3 Group Network Diagram1.4 Stream Table AnalysisIn promiscuous mode, the policy Bridge flow table is similar to the "... actions=normal", which does not differentiate the traffic and can be forwarded as normal.When
