Example 2: Configuring a Maximum Limit of Secure MAC Addresses for Specific VLANs
This example shows how to configure a secure MAC-address on interface g1/1 in a specific VLAN or
range of VLANs:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface g1/1
Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# sw mode trunk
Switch(config-if)# switchport port-security
Switch(config-if)# vlan-range 2-6
Switch(config-if-vlan-range)# port-security maximum 3
Switch(config-if)# exit
Switch# show port-security interface g1/1 vlan
Default maximum: not set, using 3072
