Generally, the failure of a vswitch is caused by the time used. As the Working Hours extend and network applications change, the chance of a problem increases greatly. A switch is an important device in a network. If a problem occurs, it will affect

A switch is an important device in a network. If a problem occurs, it will affect the entire network system. Therefore, we have analyzed the troubleshooting methods for common switch faults. Computers in the LAN are often connected to switch devices

Many vswitch users have encountered many problems due to many reasons. Here we mainly analyze the vswitch network faults caused by incorrect Switch location installation. A vswitch is a key connection device in a LAN. It has a large number of

What I want to tell you in this article is: the layer-3 switch is very technical, not only "looks beautiful", but also very beautiful to use! So what is the role of layer-3 switches in the Construction of Campus Networks and urban education networks?

Switch-case retrun break, switch-caseretrun { If statements process two branches, the if-else-if structure must be used when processing multiple branches. However, if there are many branches, the more nested if statement layers, the program is not
