cisco ethernet switch

The emergence of 10-ge switches completely realizes the convergence of private networks to the public network, and it can provide a throughput of more than one thousand G in one second, which is not supported by traditional switches. As compatible with the latest Ethernet technology, 10-Gigabit Ethernet is not only a "high-speed rebuild" of Ethernet. For the firs

The Application of Fiber-Optic Ethernet switches is becoming more and more extensive. Here we mainly introduce the ACCESS scheme of fiber-optic Ethernet switches and its practical application problems. The fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, that is,

In actual use, an Ethernet switch generally does not require both parties to send and receive data at the same time. One-way transmission devices such as printers can be used in half-duplex or even single-ticket mode, and do not need to switch back, one-way transmission devices such as printers can be used in half-duplex mode or even in a single ticket, and do no

The development process of exchange technology Ethernet switch, English for switch, also someone translates as switching, exchanger or switched hub. We first review the development of the local area network. The combination of computer technology and communication technology has promoted the rapid development of computer local area network, from the advent of t

How does a cisco switch find a loop? How to solve Loop Problems, cisco How does a cisco switch find a loop? Loop Problem Solution How can we intuitively and quickly determine whether a loop exists on a cisco

Switch Ethernet port typeEthernet port type of the switch: Access, Trunk, and Hybrid Untag common ethernet packets. The NIC of a common PC can identify such packets for communication; the structure of the tag packet is changed after the source mac address and the target mac address, with 4-bytes vlan information added,

How to solve the problem of Ethernet switch parameters the switch can be divided into Layer 2 switches, Layer 3 switches, and Layer 4 switches according to the working protocol layer, you can divide network-managed switches and non-managed switches based on whether the network management function is supported. This article will describe how to set parameters for

Step 1 in the online world: what is an Ethernet switch? a switch in the broad sense is a device that completes information exchange in a communication system. Of course, we have already popularized programmable switches, and the exchange process is automatically completed. What is an Ethernet

Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type switch, which has good scalability and supports different network types, such as Ethernet, fast Ethernet, Gigabit Ethernet, A

Ethernet switches are still commonly used. So I studied the enterprise-level Ethernet switch solution and shared it with you here. I hope it will be useful to you. As the main connection device of the LAN, the Ethernet switch is one of the fastest-growing network devices. Wi

The following article is an effective description of the ethernet switch parameter configuration problem, the switch according to the work protocol layer can be divided into a second layer of switches, third-tier switches and layer fourth switch, according to whether or not to support the network management function ca

as the core. Star: easy to manage, easy to expand, dedicated network devices are required as the core node of the network, more network cables are required, and high reliability requirements on core settings are required. A dedicated network device, such as a hub or vswitch, is used as the core node. Each host in the LAN is connected to the core node through twisted pair wires, forming a star structure. Although the star network requires more cables than the bus type, the wiring and connectors

According to researchers at the University of California, San Diego, purchasing a faster switch may be the only way to improve the network performance of the entire data center. These researchers proposed this week a network architecture that enables commercialized Ethernet switches to provide better performance at a lower cost than 10-Gigabit Ethernet switches.

At present, the development of Ethernet switches is very rapid. Here we analyze the development status of Ethernet switches. MPLS switches follow the trend of combining ATM and IP addresses. Multiprotocol Label Switching (MPLS) is a tag exchange technique between Layer 2 and Layer 3. It is specially designed for IP addresses, the high-speed switching capability of the second layer can be combined with the f

Layer-3 Ethernet switches are quite common, so I have studied the problems related to the CPU packet sending and receiving of layer-3 Ethernet switches. I would like to share them with you here, hoping they will be useful to you. Layer-3 Ethernet switches are developing rapidly. On the one hand, bandwidth and switching capacity of network devices are greatly incr

The following article describes the parameter configuration of the Ethernet switch. The switch can be divided into Layer 2 switches, Layer 3 switches, and Layer 4 switches according to the working protocol layer, you can divide network-managed switches and non-managed switches based on whether the network management function is supported.

Ethernet technology has entered the 10G era. Ethernet is no longer just a LAN technology, but a Layer 2 bearer technology from desktop to core, from enterprises to telecom operators, from LAN to Internet backbone. As a result, the 10-ge Ethernet switch, as the core of the network, is facing unprecedented challenges. In

Ethernet switches are still commonly used. So I studied whether SPOH technology has triggered the Ethernet switch revolution. I would like to share it with you here, hoping it will be useful to you. The rapidly expanding "Network Society" poses severe challenges to Ethernet switches serving as data processing centers.
