The Fiber jumper (also known as the optical fiber connector), which is the optical connector to access the optical module, also has many kinds, and can not be mutually used. The SFP module is connected to the LC fibre optic connector, while the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used optical fiber connectors in Network engineering: ①FC Type fiber jumper: The external streng

Some knowledge about storageAccording to the different transmission protocols, the network card can be divided into three kinds, one is the Ethernet card, the second is the FC network card, the third is the iSCSI network card. Ethernet Card: The Scientific name Ethernet Adapter, the transmission protocol for the IP protocol, generally via fiber optic cable or twisted pair with Ethernet switch connection. The interface types are divided into optical and electrical ports. Optical ports ar

, thus forming a network of hardware devices. So, the fiber-optic network card is the name in the end is the fiber port HBA card? In fact, the fiber-optic network card that you often refer to is the HBA card in the Fibre Channel networks. Because of the different transmission protocol, the network card can be divided into three kinds, one is Ethernet cards, the other is FC network card, the third is iSCSI network card. • Ethernet Card: Scientific name Ethernet Adapter, transport protocol fo

Supports a wide range of QOS, ACL, and hardware-based access control lists.2) L2 aggregation switch:The design principles of L2 switches aim to improve the manageability, reliability, and scalability of the network, and configure the fully Gigabit ports of the network management layer switch GSM712. In this project, ni

BGP experiment, you can even use this configuration to establish full-network connectivity, and then create a tunnel port to implement the experiment topology. During remote configuration, you can save multiple configuration files and switch between them. The configuration file named router-confg can be used as a final backup-if you accidentally delete the configuration, there will still be an available configuration after the system restarts.Conclusion: The initial enchanting phenomenon is cau

port is in the err-disable State because it detects a loop on port 20th. Check the port status Switch # showinterfa0/20 status PortNameStatusVlanDuplexSpeedType Fa0/20linktodatabackuperr-disabled562auto10/100 BaseTX This more clearly implies that the port is in the err-disabled state. Now that the port is in the wrong state, we should have a step to repeat it into a normal state.

, a wider range of cat6a/classea copper systems, and more 10gbase-t-based networking devices to support the growth of 10G connections and gain more bandwidth capacity. As we all know, UTP copper cabling can often provide a more economical cost than optical fiber for 10gbase-t channels. Electronic devices used for 10GBASE-T are more complex than electronic devices used by 1000BASE-T, but they should be much cheaper than electronic devices 10gb/s fibre
