The port of the core switch is mainly of the optical fiber type, but the price of the optical fiber port of the switch is very expensive. You must note that the optical fiber port of the switch is not stacked and can only be used for Cascade. Analyzes the connection methods and basic types of the optical fiber ports of the vswitch. Cascade uses both common ports and special MDI-II ports. A straight-through
Vswitch Optical Fiber port cascade connection mode and basic type when the two ports of mutual cascade are common port (that is, MDI-X) port and MDI-II port, should use a straight-through cable. Cross-cable should be used when both ports of mutual cascade are common ports (that is, MDI-X) or both are MDI-II ports. Whether it is 10Base-T Ethernet, 100Base-TX fast Ethernet, or 1000Base-T Gigabit Ethernet, the

Code for determining the networking type and connection status through JS
China's mobile network environment is complex. In order to provide users with a better access experience, developers hope to understand the user's current networking method and then give users a request result that meets the current network environment.
W3C provides a method to obtain the current network status navigator.
This article mainly introduces the implementation code for determining the network type and connection status through JS. For more information, see the complicated mobile network environment in China, the developer wants to know the user's current networking method, and then gives the user a request result that conforms to the current network environment.
W3C provides a method to obtain the current network
fibre port is connected successfully.
Cascade of Switch Fibre ports
Similarly, when a backbone switch is connected to a core switch, the transceiver port of the fiber must also be crossed. The connection between the core switch and the backbone switch.
Fibre jumper and switch fibre port type
Fiber jumpers are divided into single mode fiber and multimode fiber. Switch fibre ports, jumpers must be consis
