The imp
To prevent IP address theft or employee IP address tampering in a Cisco switch, you can take the following measures: binding an IP address to a MAC address and binding an IP address to a vswitch port.
1. Check the port through
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

"hard" operations on network devices. The security factor is high, but the obtained information is not accurate.
