different switches

first address in the box is the IP address, the second is the subnet mask, and the third is the default gateway. 3. Each port of s3/1-3 connects to a server. 4. cascade the switches connecting student computers to s3/4-8, and cascade the switches connecting instructor computers to ports s4/1-8, cascade the switches connected to the living area to ports s5/1-4, a

What are the differences between layer-2 and layer-3 Ethernet switches and their basic types? The following are some comparisons: after reading this article, we will be able to fully understand the layer-3 Ethernet switch. Next we will talk about the three-layer Ethernet switch process. VLAN segmentation is used to isolate inter-VLAN communication, and layer-3 Ethernet switch devices of routers supporting VLANs can be used to establish inter-VLAN comm

Switches and routers are very important devices in a networking area, where we mainly introduce network interconnection and LAN switches and router devices. The clip scheme only supports the TCP/IP protocol, but there are a variety of network layer protocols running on the existing network, such as IP, IPX, Appletalk, DECnet, Banyan, vines, etc. The key to ATM network interconnection with existing multiple

. " In large networks, especially for a large transportation management information system such as TMIS, security is critical. CoreBuilder 3500 layer-3 switches support security level and virtual subnet division. Considering that a department may be dispersed in different buildings, the virtual network in vswitch 3500 is divided not by location, but by Application Department, and the security level of each

At present, the development of routers, switches and hubs is very rapid, and the technology is more standardized and mature. First, the HUB, that is, the HUB. Its function can be simply understood as connecting some machines to form a LAN. The switch, also known as the switch-type hub, works basically the same as the hub. However, there is a difference between the two in terms of performance: the hub uses the shared bandwidth method, while the switch

address is connected, and then send the packet to the corresponding port, effectively suppress IP broadcast storms. In addition, the information package is in parallel state, with high efficiency. The forwarding delay of a vswitch is very small, mainly because the hardware design mechanism is very efficient. To support the maximum data transmission rate of each port, the bandwidth of the forwarding packet inside the vswitch must be much larger than the port bandwidth, with a powerful overall th

In daily life, the Internet access will certainly involve wireless switches, which provide users with exclusive point-to-point connections. data packets are only sent to the destination, so as to avoid a significant reduction in the bandwidth of all ports when the data volume is large, therefore, selecting a high-performance wireless switch saves a lot of trouble for future work. When used for a star structure, it acts as the center node to enlarge th

Precautions and categories for purchasing cisco Gigabit Switches. We will introduce the precautions for cisco Gigabit Switches. Many people may not know how to classify cisco Gigabit Switches, after reading this article, you must have gained a lot. I hope this article will teach you more things. At present, Gigabit Ethernet has become a strategic choice for high-

describe how to combine and deploy the above technologies on CISCO switches for typical Layer 2 attacks and spoofing, to prevent man-in-the-middle attacks, MAC/CAM attacks, DHCP attacks, and address spoofing in the exchange environment, more importantly, address management can be simplified through the deployment of the above technologies, track user IP addresses and corresponding switch ports directly to prevent IP address conflicts. At the same tim

domain. broadcast packets are transmitted across all CIDR blocks connected to the vswitch. In some cases, communication congestion and security vulnerabilities may occur. The CIDR blocks connected to the vro are allocated to different broadcast domains, and the broadcast data does not pass through the vro. Although vswitches above Layer 3 Have VLAN functions and can also be divided into broadcast domains, communication between subbroadcast domains is

subnets, the vro on the border is responsible for connecting to the upper-layer network. Dividing subnets can narrow the broadcast domain and reduce the impact of broadcast storms on the network. Each vro interface is connected to a subnet. broadcast packets cannot be broadcast by the vro. The subnets connected to different vro interfaces belong to different subnets. The subnet ranges are physically divide

The US network has been in the Chinese market for several years and won the trust of users with excellent quality, wireless network devices, firewalls, and other security devices, routers, and switches of the network have a large market share in China. These 24-port smart switches, it is also a cost-effective product for small and medium-sized enterprises. The SLM224G2 smart switch increases the intelligenc

There are many things worth learning about wireless switches. Here we mainly introduce how to effectively manage wireless switches and solve the power supply problem of Wireless AP, which is an important prerequisite for ensuring the flexibility of Wireless AP deployment location. This requires that the AP can achieve remote power supply through POE while providing local power supply. There are currently tw

The non-blocking mechanism of GE Ethernet switches provides full-line rate switching for your network, making it easy for you to use. In the network, hardware and software are just tools, the most valuable information is the information flowing in the network. With the accumulation of enterprise information data, the demand for information data backup and sharing is growing, and the requirements for storage are also increasing. The complexity of enter

Basic configurations of L3 SwitchesL3 switches play an important role in the replacement of common L2 switches in large and medium-sized networks. The reason is very simple. When there are a large number of computers in the network, it is necessary to divide them into several virtual networks to improve network security and reduce the consumption of network bandwidth by broadcast, this improves network tran

the other end. This enables the load balancing on several firewalls, so that the firewall can run in parallel, extending the performance of the firewall and eliminating the possibility of a firewall becoming a single point of failure. Unlike traditional packet switches, web switches have the ability to maintain different TCP sessions that are transmitted over E

Switch learning feature). Layer three switch: based on the traditional two layer switch, the network layer forwarding technology is adopted. We know that the host communication of different networks generally requires router forwarding, if only a local area network is divided into multiple subnets, inter-subnet communication using routers, then the communication efficiency between these subnets will be due to the router interface low speed, complex a

Edit comments:A stackable switch connects several dedicated stack modules of a vswitch to increase the port density of the network access layer exponentially. Some switches can be managed as network elements after being stacked, And the stackable switch simplifies the network structure. In fact, the stackable machine is also useful, and it has many advantages. This article focuses on the exchange advantages of Stacking machines and the challenges face

Many people think that the functions of a switch and a bridge are quite different. In fact, the basic functions of a LAN switch are the same as those of a bridge. A bridge is also called a bridge. It is a storage and forwarding device that connects two LAN networks, it can be used to connect a network system with identical or similar architecture. This not only expands the distance or range of the network, but also improves the performance, reliabilit
