Classic case study of MAC address drift The network topology is as follows: IRF virtualization is performed between the two carrier access switches (that is, two switches are virtualized into one), and VRRP hot backup is performed between the two Server Load balancer instances. The network structure is Layer 2, and the gateways of each link are located at the carrier. 5800-2 port g2/0/11 is connected to the notebook 223.1.5.41 5800-1 port g1/0/3 is

Take the Cisco 2950 vswitch as an example. log on to the vswitch and enter the management password to enter the configuration mode. Then, run the following command: Switch # config Terminal # Enter the Configuration Mode Switch (config) # interface fastethernet 0/1 # Enter the specific port configuration mode Switch (config-If) # switchport port-secruity # Configure port security mode Switch (config-If) switchport port-security Mac-address

Simply put: The IP address is the service provider to you, the MAC address is the physical address of your network card.First, IP addressFor IP addresses, I believe everyone is familiar with the 32-bit address assigned to the host using the TCP/IP protocol. The IP address is composed of 4 88-bit groups separated by dots, such as 192.168.0.1 is an IP address, which is called dotted decimal format. The IP address consists of the network address and the

Differences and connections between MAC addresses and IP addresses (Computer Network)Recently, I took a test and always encountered mac address problems. So I did some research online. I remember that I learned this knowledge when I was a sophomore, I have basically returned it to Mr. Huang Peijie, but I am very grateful to him for his patience and responsibility in teaching us the principles of computer co

Verify view Mac failure Validation of ViewState mac Failed An error was encountered while debugging Atlas today: Verify that the view Mac failed. If this reference program is hosted by a network farm or cluster, make sure that the The environment in which the error occurred: asp.net 2.0, using the UpdatePanel of Atlas, dynamically load user controls in UpdatePan

Wireless sensors have been described in detail in the previous article. As the focus of future technological development, wireless sensors are one of the two major technologies-Wireless Technology + micro-sensing technology. This article focuses on the MAC protocol classification of wireless sensor networks. Classification Based on MAC protocol of wireless sensor networks using node Access Channels Currentl

A wireless sensor network consists of a large number of low-cost micro-sensor nodes deployed in the monitoring area. A multi-hop self-organizing network system is formed through wireless communication, it is mainly used to collect, disseminate, and process sensing information. Unlike traditional wireless self-organizing networks, wireless sensor networks have a large number of nodes and are densely distributed. Due to environmental impact and energy depletion, nodes are prone to faults; environm

In the following list, "Opt" is the abbreviation of "option key" on the keyboard. "cmd" is the abbreviation of "command key" and "Ctrl" is the abbreviation of "control key. The author says that all buttons have been tested, but the translator has not used all button combinations in person, so this article is for your reference only. If you want to try button combinations that have not been used, please be careful. 1. Press ...... Click the mouse button to bring up the removable media (BOOT Rom e

Simply put, the IP address is provided by the service provider, and the MAC address is the physical address of your Nic. I. I believe everyone is familiar with the IP address, that is, the 32-bit address assigned to the host using the TCP/IP protocol. An IP address consists of four octal groups separated by dots. For example, 192.168.0.1 is an IP address, which is written in dotted decimal format. An IP address consists of a network address and a host

MAC Address Overview Mac (media access control), or MAC address, hardware address, used to define the location of the network device. In the OSI model, the third layer of the network layer is responsible for the IP address, and the second layer of the data link layer is responsible for the Mac site. Therefore, a host

Come from:http://blog.csdn.net/lonelyroamer/article/details/7630594 I. Overview The MAC algorithm combines the advantages of the MD5 and Sha algorithms and joins the key support, which is a more secure message digest algorithm. MAC (Message authentication code, messaging authentication Code algorithm) is a hash function algorithm with key, which is compatible with the characteristics of MD and SHA algorith

As a server operating system, Linux has stable services and powerful functions. Since the Linux 2.4 kernel, the NetFilter package filtering architecture has been built in. It has a powerful data packet filtering function to ensure that it is more handy when used as a software router. For example, many small and medium-sized enterprises use Linux software routers to connect their internal networks to the Internet, which is not inferior to some proprietary systems, but also advantageous in terms o

Want to learn sketch, but suffer from no Mac computer? Okay, static audio-visual you one-hour experience in Windows Mac OS and sketch charm, do not spend a penny easy to handle, quickly with static electricity to study together. Before watching the static sketch tutorials and static Xcode tutorial students, especially with Windows students, will be spit slot: How could there be such a pit Dad's tutorial!

The Ethernet MAC address uniquely identifies each Ethernet device in the world. This article describes how to obtain the MAC address and how to change the MAC address. Obtain the MAC address In the command input window of the switch, enter "show mac-address-table" to obtain

An Ethernet NIC consists of two layers of the OSI (open-party system interconnection) model. Physical Layer and data link layer. The physical layer defines the electrical and optical signals, line statuses, clock baselines, data encoding, and circuits required for data transmission and receiving, and provides standard interfaces to data link layer devices. The data link layer provides addressing mechanisms, data frame construction, data error check, transfer control, and standard data interfaces

To make the frames sent by a network adapter receive and process the frames correctly, IEEE stipulates that each network adapter has a unique ethernet address-MAC address (which is called MAC address by IEEE ). Because the addressing details are defined by MAC protocols such as 802.3 ). The MAC address has 48 bits (6 b

I. IP Address I believe everyone is familiar with the IP address, that is, the 32-bit address assigned to the host using the TCP/IP protocol. An IP address consists of four octal groups separated by dots. For example, 192.168.0.1 is an IP address, which is written in dotted decimal format. An IP address consists of a network address and a host address. The number of BITs assigned to these two parts varies with the address class A, B, and C. The network address is used for routing, while the
