Example 2: Configuring Sticky MAC Addresses for Voice and Data VLANs
This example shows how to configure sticky MAC addresses for voice and data VLANs on Fast Ethernet
interface 5/1 and to verify the configuration:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface fa5/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security maximum 3072
Switch(config-if)# switchport port-security mac-address sticky 0000.0000.obob vlan voice
Switch(config-if)# switchport port-security mac-address sticky 0000.0000.0005 vlan access
Switch(config-if)# end
Note Sending traffic to the ports causes the system to configure the port with sticky secure addresses.
Switch# show port-security address
