Workaround: try to adjust the speed and duplex mode of the router's WAN port.

I. STP algorithms are complex, but they can be divided into several steps. 1. Determine a root bridge in a switched network (all the root bridges are specified ports) 2. Determine a root port on another non-root Network Bridge. 3. Determine the specified port on a link 4. All other undefined ports are blocked. Step 2: determine the root Port 1. Minimum Cost value to the root bridge 2. Select the minimum bid of the Peer switch. 3. Select the minimum port priority of the Peer switch. 4. Select the

continuous improvement, the current popular network equipment can support 10mbps/100mbps/1gbps these three kinds of speed. Although the hardware performance of the network equipment is constantly improving, but the actual performance of the Linux system (the delivery rate) can really reach up to 1Gbps level? This is related to the performance of the processor, in general, we are running a system in which the transmission rate is less than 1Gbps (beca

structure, can refer to the following link:Http://man7.org/linux/man-pages/man7/netdevice.7.htmlThe If_nametoindex () function provides a conversion from the NIC name to index, which is used in the following example code. Such asIf you can't find this function usage, you need to install Manpages-posix-dev.Sll_hatype:arp hardware type, defined in header file The Ethernet network card type of 10Mbps. The kernel uses arphdr_xxx to represent the type of

Select start → connect to → show all connections, double-click the connection used by the network card, click the Properties button, open the Properties dialog box, and select the Advanced tab. Select Link Speed/duplex mode in the properties column, and then change "Auto mode" to "Half mode" in the Set Value column. In this way, manually 10/100m the properties of the Adaptive Network card to the 10M Half-duplex mode, so that the network card does not automatically negotiate between the network

Now many units have been built intranet, the general enterprise network is mostly using twisted-pair to connect the network card mode to communicate. The twisted-pair wires are usually 5 lines, and the transmission rate is 100MB. and the network card is a certain difference, many network cards are taken 10mbps/100mbmps Adaptive network card, that is, the transmission rate between 10MB and 100MB automatically match. For this network card, in the transm

try to replace the computer connected router network cable to speed. 6, check the WAN port rate settings If the router's WAN port speed is 10M, the speed of a broadband line larger than 10Mbps will affect the speed of the computer, please confirm that the WAN rate is set to self negotiation. In the Router management interface, click Routing Settings >> Internet settings >> Advanced settings to confirm that the WAN rate is automatic negotiation, as

Under the Win7 system, when one of the computers under the same LAN is carrying out the speed download, the other computer network speed is obviously affected. In fact, this is because in our system does not limit the speed of the case, even if only a computer will be used to run out of broadband resources, it will lead to a local area network under the influence of computer speed. So how to limit speed? We can change the speed of the network card in the system to limit the use of the computer.

more trouble 3. Performance is often not too good to meet a part of the needs of people. Classification According to the bus to divide Can be divided into the following categories: 1, ISA interface network card Due to the limitations of ISA bus, the network card of this kind of interface has been rare in the market. For now, the ISA interface's network card features a cheap price. But it has the characteristics of low transmission speed and installation trouble. 2, PCI Interface network c

Companies or units are now mostly set up a local area network, intranet for 100Mbps, through ADSL broadband connection to the Internet. The ADSL modem is connected to the 10/100 Mbps switch, and the switch is then connected to the server. When the connection is good, the PPPoE protocol is not available to computers in the intranet. What is the reason for this? Please refer to the following, it will be helpful to you Failure analysis and exclusion: according to the symptom analysis, the PPPoE pr

Seven, hardware Copy Code code as follows: $ lspci $ dmidecode $ ethtool There are a lot of servers or bare-metal status, you can look at: Locate the RAID card (with Bbu backup battery?), CPU, spare memory slot. Depending on these situations, you can get a general idea of the source of the hardware problem and the way it is improved.Is the NIC set up properly? Are you running in Half-duplex state? Speed is

transmission rate of the 1000Mbps unchanged, the Rgmii interface in the rise of the clock along and descent along both sampling data. The reference clock rises along the sending Gmii interface in the txd[3:0]/rxd[3:0], where the reference clock drops along the txd[7:4]/rxd[7:4 of the sending Gmii interface. The RGMII is compatible with the 100Mbps and 10Mbps two rates, at which point the reference clock rate is 25MHz and 2.5MHz, respectively. Figure
