Enabling and Configuring Port Security Aging
You can use port security aging to set the aging time for static and dynamic secure addresses on a port.
Two types of aging are supported per port:
• Absolute—The secure addresses on the port are deleted after the specified aging time.
• Inactivity—The secure addresses on the port are deleted only if the secure addresses are inactive for
the specified aging time.
Use this feature to remove and add PCs on a secure port without manually deleting the existing secure
MAC addresses and to still limit the number of secure addresses on a port. You can enable or disable the
aging of statically-configured secure addresses on a per-port basis.
