Virtual lan vlan) not only facilitates network security and prevents network storms, but also improves network operation efficiency and solves many other problems. The popularization of layer-3 switches creates conditions for VLAN applications. In the process of upgrading the network, I also used VLAN technology to solve the problem of network expansion. I. Network Environment When establishing a LAN, the company uses Cisco 3662 as the router, and the center switch uses the third-layer function

Today we will further recommend a web font mixin. To use web font, you must use @ font-face to import the font file before using it. The format of @ font-face is as follows: @font-face { font-family: Because browsers cannot support different font formats, we need a brain to import the font format for several minut
