Which wireless connection phase has just finished?
An 802.1X/EAP authentication exchange succeeds through RADIUS, and the subsequent WPA2 four-way handshake completes key negotiation and installation for encrypted wireless traffic. Together, these operations constitute Layer 2 authentication and encryption. Cisco documents that WPA/WPA2-EAP authentication derives key material before the four-way handshake, which generates the encryption keys.
