Configuring Port Security Chapter 19 Configuring Port-Based Traffic Control Step 8 Command switchport port-security [mac-address mac-address [vlan {vlan-id | {access | voice}}] Purpose (Optional) Enter a secure MAC address for the interface. You can use this command to enter the maximum number of secure MAC addresses. If you configure fewer secure MAC addresses than the maximum, the remaining MAC addresses are dynamically learned. Note If you enable sticky learning after you enter this command, the secure addresses that were dynamically learned are converted to sticky secure MAC addresses and are added to the running configuration. (Optional) vlan-set a per-VLAN maximum value. Enter one of these options after you enter the vlan keyword: • vlan-id-On a trunk port, you can specify the VLAN ID and the MAC address. If you do not specify a VLAN ID, the native VLAN is used. • access-On an access port, specify the VLAN as an access VLAN. • voice-On an access port, specify the VLAN as a voice VLAN. Note The voice keyword is available only if a voice VLAN is configured on a port and if that port is not the access VLAN. If an interface is configured for voice VLAN, configure a maximum of two secure MAC addresses. Step 9 switchport port-security mac-address sticky (Optional) Enable sticky learning on the interface. Step 10 switchport port-security mac-address sticky [mac-address | vlan {vlan-id | {access | voice}}] (Optional) Enter a sticky secure MAC address, repeating the command as many times as necessary. If you configure fewer secure MAC addresses than the maximum, the remaining MAC addresses are dynamically learned, are converted to sticky secure MAC addresses, and are added to the running configuration. Note If you do not enable sticky learning before this command is entered, an error message appears, and you cannot enter a sticky secure MAC address. Step 11 Step 12 Step 13 end show port-security copy running-config startup-config (Optional) vlan-set a per-VLAN maximum value. Enter one of these options after you enter the vlan keyword: • vlan-id-On a trunk port, you can specify the VLAN ID and the MAC address. If you do not specify a VLAN ID, the native VLAN is used. • access-On an access port, specify the VLAN as an access VLAN. • voice-On an access port, specify the VLAN as a voice VLAN. Note The voice keyword is available only if a voice VLAN is configured on a port and if that port is not the access VLAN. Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. 19-14 Catalyst 2960 Switch Software Configuration Guide OL-8603-04
