The differences between SVL and IVL in VLANs support L2 Switches of VLANs. The L2 forwarding and MAC address maintenance methods have changed, the following describes two vswitches with different MAC address maintenance methods. The SVL L2 Switch SVL (Shared VLAN Learning) does not attach vlan id when Learning MAC addresses and creating MAC address tables, or its MAC address table is used for all

H3C layer-3 Switch configuration: analyzes VLAN code instances. Currently, there are a lot of people using layer-3 switches, and maintenance of switches has become a problem that cannot be ignored. Only the three-tier switch is configured, which not only saves your time and effort on accessing the Internet, but also brings more highlights to your network life. Note: There are three VLANs, 192.168.10.0; 192.168.20.0; 192.168.30.0, And the subnet mask i

Router and three-layer switch experiment Demo--a gateway that acts as a two VLAN--Hundred dishes background : We know that routers have routing capabilities, so you know how to configure two gateways on a router interface (such as a two VLAN gateway)? Note that it is on one interface instead of two, and we sometimes use the three-layer switch as a router, so how do we configure the three-tier switch at this

The Extreme Summit vrovlan VLAN is configured on the Extreme Summit vrovlan with a VLAN. The port is added, and the server's IP address and route are configured, but the router cannot be connected. The vlan id problem was found at last. When you add a port to a VLAN, two modes are available: tagged and untagged. If the

Many users do not know how to buy VLAN switches. The most fundamental factor is to choose a cost-effective product that suits their needs. As enterprises pay more attention to information security, more and more enterprises begin to consider deploying Virtual LAN in the enterprise, in order to put confidential departments of some enterprises, for example, the R D department's network is isolated through the Virtual LAN to ensure data security. I. How

In the composition of wireless networks, the use of many devices deserves a detailed understanding. Today we will talk about the failure of VLAN wireless Internet access switches. The following is an experience shared by a netizen: A strange problem occurs in the VLAN of the two departments where an office area is located. Some websites on the Internet can be accessed normally, but some websites cannot; ema

Experiment topology:Objective: To: (1) Disable pc3 access without affecting hosts on other LAN(2) enable all hosts in the LAN to access the Internet. (Only one public address is available)(3) automatically obtain the Host IP address in the LAN.(4) r1 provides single-arm routing and dhcp functions to implement inter-vlan CommunicationIn accordance with the above requirements, to allow all hosts to access the Internet with only one public IP address, yo

How to add a process to remove VLAN information after a MAC frame enters the switch This article is just the understanding of how to add the removal VLAN process after the MAC frame enters the switch, please correct me if there is a mistake. The port for switches has two roles: Access port and trunk port. access ports can belong to only one VLAN, and

In a well-established LAN, how to implement LAN switch maintenance and testing skills, as well as problems encountered during LAN switch debugging, I found some related solutions on relevant forums, share with you for mutual learning and communication. In an IP address-based VLAN, the new site does not need to perform too many configurations when accessing the network, and the switch automatically divides it into different VLANs based on the network a

When we first started the network, we wrote a little bit of things we learned today for everyone to throw bricks.Topology:Lab objectives:(1) Step 1: divide four VLANs and place corresponding ports into vlan numbers.(2) Step 2: implement mutual ping between four VLANs(3) in step 3, sales, tech, and manage cannot communicate with each other, but can communicate with the server.Implementation process:Step 1: divide the

It is easy to implement the vlan configuration functions of Huawei switches. In the current vlan configuration of Huawei switches, some people may not understand the specific vlan configuration methods of Huawei switches. It doesn't matter. I have read the following parameters, you will also become an expert. This is the first interface displayed when you connect

Ask your boss, younger brother, who has just started to access the kernel. Now he is looking at the implementation of VLAN in Linux. 1. Where can I find information about VLAN implementation?All the information I have here is about bridge. I have little knowledge about VLAN. Can anyone with information share it? Thank you :) 2. Relationship between

In the wireless network composition, the use of a lot of equipment is worth a detailed understanding. So today we're going to talk about the problem of VLAN wireless internet switch failures. The following is a netizen's experience sharing: Unit one office area where the two departments VLAN appeared a very strange problem, some websites on the internet can be normal access, and some sites are inaccessible;

Cisco single-ARM routing configurationOne-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports 802.1q.The difference between dot1q and ISL: dot1q is a generic VLAN protocol model for va
