) # Remove the MAC address of the binding host Attention: The above command sets a port on the switch to bind a specific MAC address. So only this host can use the network, if the host's network card has been replaced or other PCs want to use the network through this port is not available, unless you delete or modify the port binding on the MAC address to normal use. Attention: The above functions apply to Cisco 2950, 3550, 4500, 6500 series Swit

card does not have this ability, these need to use CPU software decoding, then the computer run up more laborious. A lot of laptops under 3500 yuan use integrated graphics, and the most common 2 integrated graphics are: Intel GMA 4500MHD and ATI Mobility Radeon HD3200. The latter performance is superior to the former. More than 3500 yuan notebook computers are basically using a stand-alone graphics card. Take Lenovo and Dell computers for example: Lenovo or Dell laptops, which sell at 3500

Acquisition of depth frame and infrared frame acquisition The Kinect's infrared laser device is able to capture the depth and infrared image of the space, because the last example will be very simple. The depth value, Kinect uses a 16-bit unsigned integer to represent the depth frame with a "deep element" (depth elements, extended by the image element), in millimeters. The current

-tier switching technology, especially the three-tier switch, which enabled Ethernet switches to be the core of a large park network that could replace routers. These two technologies gradually become the network-led, routers retreat to the WAN edge, ATM simulation declared out. 4~7 Layer Exchange: Three-layer switch quickly commercial, soon emerged the concept of 4~7 layer Exchange, initially defined as the switch on the network message application recognition and QOS/ACL intelligent processi

The 10-ge core switch is still quite common. So I studied the perfect design concept of the 10-ge core switch and shared it with you here. I hope it will be useful to you. Quidway S8500 series 10-Gigabit core switches are a new generation of high-performance 10-Gigabit core route switch independently developed by Huawei 3Com, it can be widely used in the core layer of the E-government network, the core layer of the campus network and the Education Met

. Therefore, IPv6 products must pass product tests and public interoperability tests, and provide end users with information on device interoperability and consistency tests. Huawei 3Com IPv6 transition policy solution In the process of gradually transitioning from an IPv4 network to an IPv6 network to completely replacing an IPv4 network, the parts on the network are gradually replaced by new parts, the replacement order is the transition policy from

Article Title: Solaris10forx86 Nic replacement configuration strategy. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I installed solaris 10 for x86 u3 on the PC for testing, and successfully recognized the intel Nic when installing the system. Yesterday, my colleague pulled the intel Nic from my machine. Later, he gave me a

certain extent because the protocol standards are not yet mature and the implementation methods of different vendors are different. Principle 5: Prevent Network Attacks To ensure that the core switch is not affected by DoS attacks, some vendors adopt the anti-attack technology in the firewall and IDS System in the core route switch, to ensure that the core switch is more stable and strong. This can especially defend against attacks from inside the network and improve system security. However, t
