Configuring Port Security
VLAN, but is not learned on the access VLAN. If you connect a single PC to the Cisco IP phone,
no additional MAC addresses are required. If you connect more than one PC to the Cisco IP phone,
you must configure enough secure addresses to allow one for each PC and one for the phone.
• When a trunk port configured with port security and assigned to an access VLAN for data traffic and
to a voice VLAN for voice traffic, entering the switchport voice and switchport priority extend
interface configuration commands has no effect.
When a connected device uses the same MAC address to request an IP address for the access VLAN
and then an IP address for the voice VLAN, only the access VLAN is assigned an IP address.
• When you enter a maximum secure address value for an interface, and the new value is greater than
the previous value, the new value overwrites the previously configured value. If the new value is less
than the previous value and the number of configured secure addresses on the interface exceeds the
new value, the command is rejected.
• The switch does not support port security aging of sticky secure MAC addresses.
Table 1-3 summarizes port security compatibility with other port-based features.
