Recently, servers in the data center always send packets externally. After detection, it was found that many ARP spoofing attacks are good. Before learning NP, I learned how to prevent ARP spoofing, in this way, the configuration to prevent ARP spoofing is published.Cisco protects against ARP spoofing and uses Port SecurityCisco port security has three processing modes in violation of security rules. There are two solutions.Three Processing modes:Shud

Otherwise, the port cannot forward packets normally. 3. Add the current port to the specified VLAN. You can add the current Ethernet port to the specif
