[Switch-GigabitEthernet2/0/1] quit

[Switch] port-security timer disableport 30

2) Verify the configuration

After completing the configurations, you can use the following command to view the port security

configuration information:

<Switch> display port-security interface gigabitethernet 2/0/1

Equipment port-security is enabled

Intrusion trap is enabled

Disableport Timeout: 30s

OUI value:

GigabitEthernet2/0/1 is link-up

Port mode is autoLearn

NeedToKnow mode is disabled

Intrusion Protection mode is DisablePortTemporarily

Max MAC address number is 64

Stored MAC address number is 0

Authorization is permitted

As shown in the output, the maximum number of secure MAC addresses allowed on the port is 64, the

port security mode is autoLearn, the trapping for intrusion protection is enabled, and the intrusion

protection action is to disable the port (DisablePortTemporarily) for 30 seconds.

You can also use the command above repeatedly to track the number of MAC addresses learned by

the port, or use the display this command in interface view to display the secure MAC addresses

learned, as shown below:

<Switch> system-view

[Switch] interface gigabitethernet 2/0/1

[Switch-GigabitEthernet2/0/1] display this

#

interface GigabitEthernet2/0/1

port-security max-mac-count 64

port-security port-mode autolearn

port-security mac-address security 0002-0000-0015 vlan 1

port-security mac-address security 0002-0000-0014 vlan 1

port-security mac-address security 0002-0000-0013 vlan 1

port-security mac-address security 0002-0000-0012 vlan 1

port-security mac-address security 0002-0000-0011 vlan 1

#

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 traps as follows:

#Jul 14 10:39:47:135 2009 Switch PORTSEC/4/VIOLATION:Traph3cSecureViolation

An intrusion occurs!

IfIndex: 9437185
