The test of the optical cable cabling system is a necessary step for project acceptance. It is also the final process for the project contractor to honor the contract with the real estate owner. Only after the system test is passed can the cabling system be completed.
The connectivity of devices is the most basic requirement for wiring system testing. The effectiveness of jumper systems can be easily tested. It is relatively difficult to test the indicator data of communication lines, generally,
VLAN 1. Use the no switchport trunk native vlan port configuration command to return to the default status.
6) configure a group of Ports
4006 # configure terminal
4006 (config) # interface range fastethernet2/1-5
4006 (config-if-range) # no shutdown
// Note: a space must be added between the port numbers. For example, interface range fastethernet 2/1-5 is valid, while interface range fastethernet 2/1-5 is invalid.
The following example shows how to configure groups
Investment Protection and Development Options
With the development and changes of the Enterprise, you can leverage the Scalable Cisco stack architecture to ensure the synchronous development of your LAN. Cisco provides the industry's most flexible, scalable, and manageable stacking architecture for the Catalyst 3500 XL series and the Catalyst 2900 XL series switches with gigabit performance. You can create a switch stack in the same wiring room, or use the Cisco switch cluster technology to crea

transceiver circuit energy consumption management
Although the power management of embedded processors has been thoroughly studied, the energy-saving design of Wireless Transceiver systems is not enough. Wireless Communication accounts for the majority of the energy consumption of the entire wireless sensor network, so it is very important to manage the energy consumption of the Wireless
The Data encapsulation principle should be standardized. Instead of exposing the attributes of a class to other classes, we should protect them through access methods, which is conducive to avoiding the ripple effect. If the name of an attribute changes, you only need to modify its access method, rather than modifying all relevant code.

Common Ethernet interfaces include AuI, BNC and RJ-45 interfaces, as well as FDDI, ATM, Gigabit Ethernet and so on all have corresponding network interfaces, the following describes the main LAN interfaces.
(1). AuI PortThe AuI port is the interface used to connect to the coarse coaxial cable. It is a "d" Type 15-pin interface, this is one of the most common ports in the ring or bus network. The router can connect to the 10base-5 network through a coarse coaxial cable

There are many different classifications of fiber optic transceivers, and most of the attention is being paid to categories that are differentiated by fiber connectors: SC connectors, fiber transceivers, and fc/st connectors.
When using a fiber-optic transceiver to connect to different devices, you must be careful to use different ports.

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.
