Chapter 55      Configuring Port Security
Configuring Port Security on Access Ports
Note To clear dynamically learned port security MAC addresses in the CAM table, use the clear port-security 
dynamic command. The address keyword enables you to clear a secure MAC addresses. The interface 
keyword enables you to clear all secure addresses on any interface (including any port channel interface). 
The VLAN keyword allows you to clear port security MACs on a per-VLAN per-port basis.
Examples of Port Security on Access Ports
The following examples are provided:
• Example 1: Setting Maximum Number of Secure Addresses, page 55-11
• Example 2: Setting a Violation Mode, page 55-11
• Example 3: Setting the Aging Timer, page 55-11
• Example 4: Setting the Aging Timer Type, page 55-12
• Example 5: Configuring a Secure MAC Address, page 55-12
• Example 6: Configuring Sticky Port Security, page 55-13
• Example 7: Setting a Rate Limit for Bad Packets, page 55-13
• Example 8: Clearing Dynamic Secure MAC Addresses, page 55-14
Step 11
Switch(config-if)# [no] switchport port-security 
mac-address mac_address sticky [vlan [voice | 
access]]
Specifies the sticky mac-address for the interface.
When you specify the vlan keyword, the mac-address 
becomes sticky in the specified VLAN.
To delete a sticky secure MAC addresses from the address 
table, use the 
no switchport port-security mac-address mac_address 
sticky command. To convert sticky to dynamic addresses, 
use the no switchport port-security mac-address sticky 
command.
Note This command only applies to access, PVLAN 
host, and PVLAN promiscuous mode. For more 
details on PVLAN or trunk or regular trunk mode, 
refer to the “Configuring Port Security on Trunk 
Ports” section on page 55-17.
Step 12
Switch(config-if)# end 
Returns to privileged EXEC mode.
Step 13
Switch# show port-security address 
interface interface_id 
Switch# show port-security address
Verifies your entries.
