This article introduces the knowledge of switch stack and the principle of switch stack. There are many problems with switch stack on the network. For vswitches of various models, a q A topic about switch stack is provided below. I hope to give all questions about switch st
IntroductionTraditional routers have isolated networks, isolated broadcasts, routing and forwarding, and firewall operations in the network, and as the network continues to evolve, the load of routers is growing rapidly. One of the important reasons is that the VLAN (virtual local area network) technology is widely used in networks because of security and management convenience. VLAN technology can logically isolate different network segments, ports, or even hosts, and the communication between
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 vswitches in a LAN. In such a network environment, the administrator needs to reasonably deploy the vswitch based on its performance and characteristics, because your improper deployment will pose hidden risks in

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 only huge but also difficult to understand. therefore, the C language provides a condition selection statement specifically used to process multi-branch structur

Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on different ports on the same
