Issuing the display port-security interface command after the number of MAC addresses learned by
the port reaches 64, you will see that the port security mode has changed to secure. When any frame
with a new MAC address arrives, intrusion protection is triggered and you will see trap messages as
follows:
#May 2 03:15:55:871 2000 Switch PORTSEC/1/VIOLATION:Traph3cSecureViolation
An intrusion occurs!
IfIndex: 9437207
Port: 9437207
MAC Addr: 00:0F:1F:86:32:32
VLAN ID: 1
IfAdminStatus: 1
In addition, you will see that the port security feature has disabled the port if you issue the following
command:
[Switch-GigabitEthernet2/0/1] display interface gigabitethernet 2/0/1
GigabitEthernet2/0/1 current state: Port Security Disabled
IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: 000f-cb00-5558
Description: GigabitEthernet2/0/1 Interface
......
The port should be re-enabled 30 seconds later.
[Switch-GigabitEthernet2/0/1] display interface gigabitethernet 2/0/1
GigabitEthernet2/0/1 current state: UP
IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: 000f-cb00-5558
Description: GigabitEthernet2/0/1 Interface
......
Now, if you manually delete several secure MAC addresses, the port security mode of the port will be
restored to autoLearn, and the port will be able to learn MAC addresses again.

Network requirements
The client is connected to the switch through port GigabitEthernet 2/0/1. The switch authenticates the
client by the RADIUS server. If the authentication succeeds, the client is authorized to access the
Internet.
z
RADIUS server 192.168.1.2 functions as the primary authentication server and the secondary
accounting server, and RADIUS server 192.168.1.3 functions as the secondary authentication
server and the primary accounting server. The shared key for authentication is name, and that for
accounting is money.
