In the past, vrouters and hubs were often used in the network, but now many networks use vswitches. How do I face the challenges of routing networks and switching technologies? Currently, vswitches are dominant in the network market, because of

1. Planning VLANThe LAN with eight computers is divided into two virtual LAN: VLAN1 and VLAN2. PC1 and PC2 both belong to VLAN1 and vlan2. 1. To identify different computers in the network, you must assign a unique IP address to each computer. An

As a business customer project, "Tong" is very profitable, just like "chicken ribs. Based on the actual implementation cases, this paper discusses and summarizes several technical means, and strives to help schools achieve "School-to-school

I. What is layer-3 Switch and VLAN? To answer this question, let's first look at the working principle of Ethernet. The working principle of Ethernet is that data that is combined into a frame by byte formed by binary bits is actually some electric

Although VLAN is not the best network technology, this method for logical segmentation of network nodes is used by many enterprises. VLANs are configured in enterprise networks in multiple ways, including network security authentication, roaming

1. Introduction of PVLAN 740) this. width = 740 "border = undefined> There is such a requirement in practical applications, as shown in the networking diagram. 3026 is associated with a cascade of 2016 and each port under 2016 is required to be

The rapid development of the current exchange technology has also accelerated the application speed of the VLAN-Virtual Local Area Network (VLAN-Virtual Local Area Network) technology, especially on the current campus Network. By dividing campus

In the face of increasing diverse transmission business needs, it is important for communication operators to establish a transmission network. An automatic switching Optical Network (ASON) and an integrated service transfer platform (MSTP) device

Vmps server Configuration To use VMPS, you first must create a VMPS database and store it on a TFTP server. the VMPS parser is line based. start each entry in the file on a new line. the example at the end of this section corresponds to the

With the explosive growth of today's network business traffic, and the business flow pattern changes to more business flows across the subnet boundary, the business flow through the router is also greatly increased, network bottlenecks caused by low

A layer-3 switch is an unfamiliar product in the industry. Although it is much better than the data forwarding function of a traditional router, it is still suspected that a layer-3 switch can completely replace a router. The reason is probably

Exchange Technology is a simplified, low-cost, high-performance, and high-port intensive exchange product. It reflects the second-layer operations of complex exchange technology in the OSI reference model. The difference with the bridge adapter is

Supervisor Engine 32 expands the Intelligent Service of Supervisor Engine 720 to the access layer, and provides cost-effective performance for LAN access, WAN edge and Metro Ethernet access. Comparison of features of several Cisco

Nowadays, network security requirements are getting higher and higher, and a LAN sometimes wants to be inaccessible to each other. I mainly want to introduce how cisco switches can meet your needs.Implementation Methods in cisco low-end switches:1.

Because a vswitch has many advantages, its application and development speed is much higher than that of a hub. There are various types of vswitches, mainly to meet the needs of different application environments. This article will introduce some

Traditional network security technology focuses on system intrusion detection, anti-virus software or firewall. How is internal security? In the network security structure, switches and routers are very important, and each layer in the layer-7

DescriptionThis document describes how to recover a password on a Cisco cs500 communication server. The Cisco cs500 does not have a console port so to recover a password you must erase the configuration then configure the server again.

If you are in charge of a small network, whether it is your home network or a small enterprise network, or sooner or later you will face this problem: A small number of users occupy most of your bandwidth resources. The culprit is usually the person

All subnet masks in the simple topology are 255.255.255.0 ):PC (10.1.1.2) --- E0 (10.1.1.1) [router] S0 (192.1.1.1) --- S1 (192.1.1.2) [RouterB] One-way access to the network actually implements the basic functions of the firewall: I am an intranet,

With the development of the routing industry, the soft route upnp technology is more widely used. Here we mainly analyze how to enable the soft route upnp function. Upnp: Universal plug-and-play (upnp) is a common architecture for peer-to-peer
