Switch port security (MAC address binding)

Switch port security, is a switch filtering policy, that is, one port of the switch to bind a fixed MAC address, so that other MAC address when access to trigger policy, down port or denial of service

The following is the topology diagram

　　

Switch configuration

　　

Enable access to privileged mode

conf t into global configuration mode

Hostname Modifying the switch name

No IP domain-lookup remove domain name resolution

Interface Vlan1 into Vlan1

IP address 192.168.1.1 255.255.255.0 configuring Vlan1 IP addresses (that is, configuration management addresses)

No shutdown activation port

Exit return to upper level

Interface F0/1 Entry Interface 0/1

Shutdown shutdown Port

Switchport mode access Modify port modes

Switchport port-security Modify port to Safe mode

Switchport port-security 00E0. b0ea.6035 the host MAC address with the port, where the MAC address is the address of the pc-host 1

Switchport port-security maximum 1 Setting the maximum number of MAC addresses is 1

Switchport port-security violation shutdown set response policy, here is the shutdown port

End returns to privileged mode
