An Ethernet switch comes with a serial cable for switch management. First, insert one end of the serial port cable into the serial port on the back of the switch. remote management cannot be implemented. So which method you use depends on your security and manageability requirements. Currently, many household switches have reached 100 Mbps, which can meet the needs of most users. Currently, switches have quickly replaced hubs and become the preferred

An improper port connection between Ethernet switches in Ethernet may cause a network loop. If the related switch does not enable the STP function, such a loop will lead to endless data packet forwarding, forming a broadcast storm, this causes network faults. One day, we found a problem with a VLAN in the campus network performance monitoring platform-the connection between the access switch and the campus

Vro functions are more powerful than vswitches, but the speed is relatively slow and expensive. The ethernet switch has both the ability to forward packets at the wire speed and the good control function of the vro, therefore, it has been widely used by many enterprises. "Switch" is the most frequently used word on the network today. It can be applied on any occasions from the bridge to the ATM to the telephone system, so you cannot figure out what is

I, Ethernet IIEthernet Type II Ethernet frames have a minimum length of 64 bytes (6+6+2+46+4) and a maximum length of 1518 bytes (6+6+2+1500+4). The first 12 bytes respectively identify the source node MAC address of the sending data frame and the destination node MAC address of the receiving data frame.The next 2 bytes identify the upper-layer data type that is carried by the

Abstract: This article introduces the hardware implementation method of Ethernet MII Interface Based on FPGA and extended functions. The hardware structure consists of the control signal module, divider, asynchronous FIFO buffer, and 4b/5b encoding. Key words: M Ethernet MII; FPGA; Parity divider; 4b/5b codec; asynchronous dual-port FIFO Introduction Traditional PC-centered Internet applications have now be

For most businesses in the Ethernet network, the operator cannot fully control the client device or media physically. Operators must logically control users or devices to operate and manage broadband services. This control process is mainly achieved through authentication and authorization of users and user devices. Analysis of Ethernet user access authentication technical requirements Due to the increasin

This article mainly introduces the Ethernet MAC address of the CISCO router IOS, what is the MAC address, and the configuration introduction. I believe this article will help you. Most of you may know what an Ethernet MAC address is, but you may not know how to apply a MAC address in a Cisco Internet Operating System. An Ethernet MAC address uniquely identifies e

The upper application encapsulates the data into an IP packet and then encapsulates it into a frame (the router receives a data frame, forwards a data frame, not a packet, he simply takes the number of received frames apart, exposing the three-layer header, The IP address in the header in the packet is only to determine the destination of the forwarding. frame = Frame Header control information + data part + Frame endThe format of the frame is determined by the encapsulation protocol of the i

Ethertype: Ethernet Type field and ValueEthertype is a field in an ethereframe. It is used to specify the Protocol applied to the frame data field. According to 802.3, the length/ethertype field is a field of two eight character segments. The meaning of the two is one, depending on the value. In quantitative evaluation, the first eight-byte field is the most important. When the field value is greater than or equal to the decimal value 1536 (that is, t

Ethernet switches are still commonly used. So I studied the intelligent features of Ethernet switches and shared them with you here. I hope they will be useful to you. Enterprise applications are surging to Promote the Development of Ethernet switches. Ethernet has the advantages of simple connection and better perform

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. With the continuous development of switching technology, the price of
