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

Role of the switch serial port (Trunk: The following two encapsulation types can be used for relay over Ethernet through the serial port of the switch: -IEEE 802.1Q -ISL (Inter Switch Link, Cisco private) Procedure Step 1: Add a VLAN to the vswitch Switch1 # vlan database Switch1 (vlan) # vlan 2 Switch1 (

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

QoS for user service quality assurance): currently, Ethernet only provides the best-effort mechanism, which is difficult to meet real-time service requirements when congestion occurs.4. User management problems.5. User billing and authentication problems.In addition, there are also problems such as how to save the legal IP address of the public network, power supply of BAN equipment, and so on.

1. VLAN: Virtual LAN, is the logical combination of switch ports, VLAN work in the second layer of OSI, a VLAN is a broadcast domain, the communication between the VLAN is through the 3rd layer of routers to complete. 2. VLAN Advantages: Broadcast problem of 1> control net

VLAN generation mainly to the design of local area network increased flexibility, so that network administrators in the division team, no longer limited by the user's physical location. VLANs can be implemented on one switch, or across switches. It can be divided according to the location, function or department of the network user. VLAN features flexibility and scalability, and using

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

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

Two vswitch configuration modes: Configure VLAN Based on port division as an example. Vswitch configuration modes can be divided into two categories: one is the configuration mode represented by a CISCO switch, and the other is the configuration mode represented by a Huawei or H3C switch. In fact, the two configuration modes are not essentially different, but the command names and configuration methods are different. If you grasp the basic principles
