equipment. There is also a startup script file/etc/sysconfig/network-scripts/ifcfg-eth0, the MAC address in the file is the physical address of the original eth0 NIC, and the virtual machine assigns a new physical address to eth1. Therefore, the information in the startup script does not match the actual information, the MAC address information modified to 70-p

Mac tips-it takes some time for Mac (MACOs Pro) to easily access Windows network sharing. In a word, it's "great "! Of course, there are also some unpleasant times. For example, if the keyboard and keyboard position have changed, use the eclipse shortcut key to make my fingers twist. If you want to watch avi and mkv, y

before the PAC is emitted, send an ARP request to find the MAC address M1 of the First intermediate node C1 that it must go through to reach ip_b, and then encapsulate (encapsulation) These addresses in their packets: ip_a, Ip_b,mac_a, and M1. When the PAC is passed to C1, it is ip_b by ARP according to its destination IP address, finds the MAC address M2 of the Second intermediate node C2 it is going thro

physical media. 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. This address has nothing to do with the network, that is, no matter where the hardware with this address (such as NIC, Hub, or router) is connected to the

the maximum number of MAC addresses allowed, the switch system receives new data frames. For any of the above reasons, the port security rules are eventually violated. In the end, they will be "punished ". The switch is automatically detected. When any illegal data frame is detected, timely measures are taken to ensure the security of the enterprise network. Next, let's analyze what the switch will do. The

Virtual Machine Fedora 14 settingsFirst, make sure that the IP addresses of Fedora 14 are in the same CIDR block when you do not need to share the network. Use the default one. For example, my address is 10.211.55.6 and the MAC address is 192. XXX. XX. XXX.Let's start:I. Right-click

, finds the MAC address M2 of the Second intermediate node C2 it is going through, and then transmits the packet with M2 to C2. So and so on, until finally found the address of the Host B with the IP address of ip_b Mac_b, eventually transmitted to host B. During transmission, ip_a, ip_b, and mac_a are unchanged, while the MAC address of the intermediate node is constantly changing through ARP (M1,M2,M3) un

So and so on, until finally found the address of the Host B with the IP address of ip_b Mac_b, eventually transmitted to host B.　　During transmission, ip_a, ip_b, and mac_a are unchanged, while the MAC address of the intermediate node is constantly changing through ARP (M1,M2,M3) until the destination address is mac_b. As described above, we can conclude that the IP address and
