How to judge the network loop Because almost all newly purchased switches support the port loop monitoring function, we can use this function to automatically determine whether a network loop occurs on the specified communication port. Once the loop monitoring function is enabled on the specified Ethernet communication port, the switch device can automatically and periodically scan and monitor all communication ports to determine whether the

Study on the target Switch

When another vswitch in the LAN is not attacked by a network virus, it is likely that the performance of the vswitch is relatively stable and the switch system cannot be remotely managed, I hope this article will teach you more things. As one of the core devices in the LAN, the target switch's performance directly determines the network's data transmission performance. However, after a long period of work, the swi

Layer-3 Switch: Multiple forwarding of one route

Layer-3 Switch: the principle of layer-3 switch is that two hosts A and B Using IP addresses communicate with each other through the layer-3 switch. When Site A starts sending, it compares its IP address with the IP address of Site B to determine whether Site B is in the same subnet as it. If the destination site B and the destination site A are in the same subne
