Chapter 9 Configuring Port-Based Traffic Control
Configuration Example
Switch(config-if)# no shutdown
Switch(config-if)# switchport protected
Switch(config-if)# end
This example shows how to block unicast and Layer 2 multicast flooding on a port:
Switch# configure terminal
Switch(config)# interface fastethernet0/1
Switch(config-if)# no shutdown
Switch(config-if)# switchport block multicast
Switch(config-if)# switchport block unicast
Switch(config-if)# end
This example shows how to enable port security on a port and to set the maximum number of secure
addresses to 50. The violation mode is the default, no static secure MAC addresses are configured, and
sticky learning is enabled.
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security maximum 50
Switch(config-if)# switchport port-security mac-address sticky
This example shows how to configure a static secure MAC address on VLAN 3 on a port:
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security mac-address 0000.02000.0004 vlan 3
This example shows how to enable sticky port security on a port, manually configure MAC addresses for
data VLAN, and set the total maximum number of secure addresses to 10:
Switch(config)# interface FastEthernet0/1
Switch(config-if)# no shutdown
Switch(config-if)# switchport access vlan 21
Switch(config-if)# switchport mode access
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security maximum 10
Switch(config-if)# switchport port-security violation restrict
Switch(config-if)# switchport port-security mac-address sticky
Switch(config-if)# switchport port-security mac-address sticky 0000.0000.0002
Switch(config-if)# switchport port-security mac-address 0000.0000.0003
Switch(config-if)# switchport port-security maximum 10 vlan access
This example shows how to set the aging time as 2 hours for the secure addresses on a port:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# switchport port-security aging time 120
This example shows how to set the aging time as 2 minutes for the inactivity aging type with aging
enabled for the configured secure addresses on the interface:
Switch(config-if)# switchport port-security aging time 2
Switch(config-if)# switchport port-security aging type inactivity
Switch(config-if)# switchport port-security aging static
This example shows how to configure port security on a PVLAN:
Switch(config)# interface GigabitEthernet0/8
Switch(config-if)# switchport private-vlan mapping 2061 2201-2206,3101
Switch(config-if)# switchport mode private-vlan promiscuous
Switch(config-if)# switchport port-security maximum 288
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security violation restrict
