There are three solutions available in Cisco. solution 1 and solution 2 provide the same functionality, that is, bind the MAC address Nic hardware address of the specific host to the specific switch port). solution 3 is to bind the MAC address Nic hardware address of the specific host to the specific switch port at the same time) and IP address.1. solution 1-Port

The IP address is the service provider to you, the MAC address is the physical address of your network card.1. MAC AddressIn the OSI (Open System interconnection, open systems interconnect) 7-Layer Network Protocol (physical layer, Data link layer, network layer, transport layer, Session layer, presentation layer, Application layer) Reference Model, the second la

IP-MAC bound switch settings 1. solution 1: bind a port-based MAC address to a Cisco 2950 switch as an example. log on to the switch, enter the management password to enter the configuration mode, and run the following command: switch # config terminal # enter the configuration mode Switch (config) # Interface fastethernet 0/1 # enter the specific port configurat

I. Ideas (mainly used in LAN) It is easy to obtain the Client IP address through the Web. It can be parsed from the datagram (Request object) sent by the client to the web server. However, in actual application, the proxy server must be considered, router forwarding and so on. The process of obtaining a MAC address is complex. Because the request object sent from the client to the server does not contain th

How to bind an IP address to a MAC address on a Linux route ========================================================== ==============Carefully craftedArticleHttp://www.usingdo.net/usingdonews/ System========================================================== ============== In some systems, we want several IP addresses in the Intranet to connect to the Internet

Whether the same network segment can do the same IP and MAC address,In fact, you can completely change the IP of the two computers to the same as the Mac, not only the internet but also no IP conflict. This method can not only break through the routing blockade used in the A

MAC address MAC (Media access control or medium access control) address, which is a translation of media access controls, or physical addresses, hardware addresses, to define the location of network devices. In the OSI model, the third layer of the network layer is responsible for the IP address, and the second layer of data link is responsible for the

I read books related to network basics a while ago. I had a question: Why do I have a MAC address and an IP address? Can the two be combined into one? The current logic is as follows: During data transmission, the vro can view the IP address of the data packet and compare it with the "IP Set: Next Hop

I. Application introductionBinding an IP address to a MAC address is to bind the IP address of the computer to a MAC address on the vro interface. This prevents problems caused by unauthorized IP address modification on the terminal and ensures network stability.In the LAN p

MAC address: In the OSI (Open System Interconnection) layer-7 Network Protocol Reference Model (1), the second layer is the data link ). A mac address is also called a physical address, hardware address, or link address. It is written into the hardware when produced by a network device manufacturer. Both the IP address and MA
