A loop problem occurs in the use of wireless networks. Where is the problem? Who is the culprit? The author of this article gives you a detailed description of how to set up your own experience. Unit A subnet has been working normally, but I found that workstations in subnet A recently cannot access the LAN server. After some careful checks, I can see that the new switch devices in subnet A are often unable to connect to the core switches in the LAN. Considering that workstations in other subnet

network Interface (interface) is the network hardware device in the operating system representation method, such as NIC in the Linux operating system with EthX, is a positive integer starting from 0, such as eth0, eth1 ... ethX. And the common cat and ADSL interface is pppx, such as ppp0 and so on;all available network cards, names, configuration files in the mac

IPV4 Address:We know that at the network layer (the Internet layer of TCP/IP architecture), one of the most important protocols is IP protocol, is now in the IPV4 and IPv6 transition period, but at present, IPV4 is still mainstream, so the main Ipv4.Basic IP Address format:The format of the internal IP address of the computer is represented by a 32-bit binary number, in order to make people seem convenient, usually using dotted decimal to represent th

IP Subnet Partitioning First, before we learn about subnetting, let's review the knowledge of IP addresses and learn about public and private IP addresses: There are millions of hosts on the Internet, in order to differentiate these hosts, each host is assigned a dedicated address, called an IP address. The Internet IP address is unified by the NIC (Internet Network information Center) for the planning and management of global addresses, while I

Fault details:Network Communication is suddenly interrupted, some VLANs cannot access the Internet, and access to other VLANs is also interrupted. Ping packet testing is performed in the IDC, it is found that the ping packet from the central switch to the host
