Pre-Shared Key

This is the security key used to encrypt communications 
between the NWA and its managed APs. This key is used to 
encrypt DTLS (Datagram Transport Layer Security) 
transmissions. Enter 8~32 English keyboard characters.

The proprietary AutoPSK protocol transfers the DTLS key 
from the NWA to the managed APs automatically.

Registration Type

This controls whether the NWA manages all CAPWAP-
enabled APs that transmit management request packets, or 
requires the user to select which such APs to manage.

• Select Manual to choose which APs to manage (select 

the APs you want to manage in the 

Controller > AP 

 screen).

• Select Always Accept to manage any AP on your 

network that transmits a CAPWAP request for 

management.
