Experiment 1: Port-security
1.SW1 and SW2 create VLAN10,R1-R4 partition to VLAN10, and assign IP statically
2. The Fa0/24 shutdown;Fa0/23 between SW is specified as access and divided into VLAN10
3. Enable Port-security in the Fa0/23 interface of SW2, and the specified interface can learn up to 3 MAC addresses. Observe the status of SW2 Fa0/23
4. Three kinds of illegal actions of experimental port-security
5. Three ways of learning mac-address of experimental port-security
6. Set the aging time of the MAC address dynamically learned by port-security to 1min
The experiment is complete, restore the configuration
