Port Security Configuration Guidelines
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.
