IP address and MAC address relationship: IP address is based on the current IPV4 standard specified, not subject to hardware limitations easier to remember the address, length 4 bytes. The MAC address is the physical address of the network card, stored in the EPROM of the network card, and the hardware is related, more difficult to remember, length of 6 bytes.
Although in the TCP/IP network, the computer o
The following three options are available in Cisco, and Scenario 1 and Scenario 2 implement the same functionality, which is to bind a specific host's MAC address (the NIC hardware address) on the specific switch port. Scenario 3 is the MAC address (NIC hardware address) and IP address of the specific host that is bound on the specific switch port.1. Protocol Port-based

Mac layer Attack rumor address floodA common two-layer attack or switch attack is a Mac flood, with an intruder using a large number of invalid source MAC addresses, which can cause the switch's cam table to overflow, because the switch cannot find the port corresponding to the destination MAC address in the
Everyone knows that in real life, each of us has our own ID number-ID card number. You can go to the police station to change your name, however, your ID card number cannot be changed as your name changes. In the online world, we often hear the concept of IP addresses. However, MAC addresses are rarely mentioned. We often only know IP addresses, while MAC addresses are the heroes behind the scenes. In our d
