Lab objectives:1. Master the configuration of the switch Tag VLAN;2. master the basic configuration methods of layer-3 switches;3. Master how to configure VLAN routing for layer-3 switches;4. layer-3 switches are used to implement VLAN visibility and mutual communication;Technical Principles:A layer-3 Switch has the network layer function. The principle of implem

Failure phenomenon: VLAN is a kind of virtual local area network, through VLAN can make the physical location in different network segment of the device group, can communicate as on the same network segment. This ensures that the reply packet always has the same VLAN ID tag as the incoming request packet. Packets that are passed in a

Cisco router configuration manual Virtual LAN (VLAN) routing 1. The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing the physical connection of the network, the wo

VLAN-based DHCP address pool implementation in OVS, ovsvlandhcp Preface 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

The introduction of vlan of a Huawei switch and three VMPS modes. In the explanation of vlan of a Huawei switch, there are three VMPS modes (but User Registration Tool, namely URT, only supports open mode ). How to configure dynamic vlan and VMPS of a CATALYST 4500 series switch? This article takes cisco ios 12.2 (31) SGA as an example. 1. Introduction to VMPS: V

In fact, the essence of a layer-3 switch is a layer-2 switch with the routing function. The routing mainly belongs to the network layer function in the OSI reference model, so the layer-3 Switch also has the routing kinetic energy. Now, we know that computers with different VLANs can communicate with each other as long as they can provide routes between VLANs. However, if a router is used for inter-VLAN routing, as the traffic between VLANs increases,

2618 switch VLAN configuration Switch A and switch B are connected through port 16. Port 1 of Switch A and Port 2 of Switch B are members of VLAN2, port 2 of vswitch A and port 4 of vswitch B are members of vlan3. 1.15 configuration steps vswitch A is configured as follows: zte (cfg) # set vlan 2 add port 16 tag // add port 16 to VLAN 2, and type tagzte (cfg) # s

VLAN (virtual LAN), translated into Chinese is a "virtualized local area network". The physically connected network is divided into a plurality of logical independent virtual subnets, originally, the second layer switch can only build a single broadcast domain, but with the VLAN function, it can divide the network into multiple broadcast domains.The switch allows the LAN to be divided into multiple VLANs, a

1. Networking requirements: 1. switchA and SwitchB use trunk for interconnection. Mutual access is allowed between PCs with the same VLAN. Mutual access is prohibited between PCs with different VLANs. PC1 and PC2 are located in different VLANs. You can set the IP address of VLAN Interface 10 of the SwitchB layer-3 Switch to 10.1.1.254/24, when the IP address of VLAN
