Enabling and Configuring Port Security Aging
You can use port security aging to set the aging time for all secure addresses on a port. Two types of
aging are supported per port:
AbsoluteThe secure addresses on the port are deleted after the specified aging time.
InactivityThe 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.
