• All the PMK cachings are deleted when the setting data is saved to the RS-AP3.
• Up to 16 PMK cachings can be held in each wireless LAN.
When the amount of the PMK cachings exceed more than 16, the older PMK cachings are deleted.
Also, the PMK cachings that exceed the PMK Caching Timeout are deleted. (
