Typical topology chart for port security
When the interface enabled Port security function, configure the maximum number of the
secure MAC addresses allowed by a interface to be 10, the interface allows 10 users to
access the internet at most. If it exceeds the maximum number, the new user cannot access
the internet, so that it not only
limit the user’s number but also access the internet safely. If
configuring the maximum number of the secure MAC addresses as 1, only HOST A or HOST B
is able to access the internet.
Configuration process:
#Configure the switch.
Switch(config)#interface Ethernet 1/1
Switch(config-if- ethernet1/1)#switchport port-security
