WPA3-Personal PSK passphrase mismatch

WPA3-Personal PSKパスフレーズを間違えて入力した場合のログを見てみましょう。
Auth Commit、Auth Confirm まで確認できますが、Assoc Request/Response および 4-way handshake を実施していないことが分かります。

また、show log security コマンドにて、Auth Confirm でエラーが発生しているログが確認できます。

[English Version]
Let's see when WPA3-Personal PSK passphrase mismatch happens.
We can see Auth Commit and Auth Confirm, but we can not see Assoc Request/Response and 4-way handshake.

From show log security, we can see Auth Confirm error.
