15.3 Example of PORT SECURITY

Figure 15-1: 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.
MAC address table or a MAC
address is configured to
several interfaces in same
VLAN, both of them will violate
the security of the MAC
address.
Enable port-security aging
entry of the interface, specify
aging time or aging type.
Clear the secure MAC entry of
the interface.
Show port-security
configuration.
