At present, with the pace of network product updates accelerating, a considerable number of enterprises and institutions have eliminated and redundant network devices. It would be a pity to discard or discard them. At this time, it is a good idea for network administrators to use them to build a small online lab platform. In addition, there are many training courses, and we also need to build an online lab platform for students of the Learning Network to practice. The following steps allow you t

. Whether a person can achieve remarkable results is related to his talent. The Ugly Duckling can change to a swan, but the premise is that it must be a swan egg. So he must first be a good seed. 2. His advantages must match his position It is impossible for Yao Ming, who is more than 2 meters tall, to practice gymnastics. An excellent superior manager is actually like a catalyst. It is not an internal cause, but it is an important driving force. 3. H

tools for everyday. presumably,You will ask now why we must develop first a life support system for our moon-traveling astronauts, before we can build a remote-reading sensor system for heart patients. the answer is simple: significant progress in the solutions of technical problems isFrequently made not by a direct approach, but by first setting a goal of high challenge which offers a strong motivation for innovative work, which fires the imagination and spurs men to expend their best efforts,

"Introduction" Cisco switch Catalyst 3750-e Series production in 2007, the original system is very old, in order to let it out of the spring, we can upgrade its system. Pre-upgrade preparationFirst we need a new version of the Catalyst 3750-e Series Cisco switch ISO file, online searchable to many, here we recommend a 2015-year version of the download link is:Cisco switch

The same is true of the three technologies. Before you integrate, you need toAsp.net,spring.net,nhibernate have some knowledge, it is best to have some experience, because for no reason to put 3 technology together, will make small awkward, in fact, like the con

Software and Hardware running on Cisco Catalyst 2950, Catalyst 3550, and Catalyst 4000 series switches can also implement appropriate traffic classification and isolation on all ports. VLAN attack 2.

After the physical connection is complete, we need to turn on the computer and switch power for software configuration. Next we will describe this configuration process with a Cisco netmanager switch "Catalyst 1900. Before entering the configuration, we also need to enter the system. The steps are as follows:Step 2: power on the computer connected to the vswitch and run one of Windows 95, Windows 98, or Windows 1st.Step 2: Check whether the "Super Ter

Layer-3 switches are quite common, So I studied how to use layer-3 switches to ensure data security. I would like to share with you here, hoping they will be useful to you. The backbone network topology of Jiangxi sanjiu yigong Co., Ltd. is multi-level star Gigabit Ethernet. A high-performance switch Cisco Catalyst 4006 with multiple 1-gigabit ports and 10-Gigabit ports is placed in the center of the science and technology building as the core switch

Layer-3 switches are quite common, So I studied how layer-3 switches can ensure network security. Here I will share with you, hoping to help you. A high-performance switch Cisco Catalyst 4006 with multiple 1-gigabit ports and 10-Gigabit ports is placed in the center of the science and technology building as the core switch of the backbone network. The company's master server and high-performance workstation use the Gigabit switching port of the centra

telephones into independent Logical Networks. Even if the data and voice infrastructure are the same, no impact will be given. The affiliated VLAN feature allows the phone to be placed in its own VLAN without any end user interruption. You only need to simply insert the phone into the switch, and the Ethernet switch can provide the required VLAN information to the phone. Trusted settings enable the switch to ensure that the voice information is obtained from the IP phone for high priority proce

Most network administrators use port mirroring, data generation technology, or passive networks to configure network detectors. Although these solutions can work barely, they will have negative effects, affect network performance and response speed, and perform tedious and slow operations. To address these problems, Cisco has released its network analysis module NAM. NAM is designed for Cisco switches of the Catalyst 5000, 6000, and 6500 series. It i

Assume that the Cat-1 is a software bridge made by an earlier Cisco MGS or AGS Router (a 2-tier forwarding capability is approximately equal to 10,000 packets per second), and the remaining six devices are Catalyst 5500 or 6000 switches (2-tier forwarding capabilit

We should also put forward the problem, find out the root cause of the problem, sum up experience and lessons, and severely criticize the persons responsible for the accident, and give punishment. This may be difficult to implement in the IT team. I have read an article 3. harmonious te
