Authentication
To use Pre‐Authentication, you must have the following
802.1x Authentication
Hexadecimal uses a key made up of a string of 64 hexadecimal numbers
The 802.1x EAP packets are also used to pass dynamic unicast session keys and static broadcast keys to wireless clients. Session keys are unique to each client and are used to encrypt and correlate traffic passing between a specific client and the access point. You can also enable broadcast key rotation, so the access point provides a dynamic broadcast key and changes it at a specified interval
If you specify RADIUS MAC for this default interface or VAP, you must specify the following parameters
