hmm ... If i true undestand parametr mac-table-aging-time specify aging time, i.e. time afet wich than mac address will be delete from ethernet-switching table (mac-address table).
When dot1x (mac) authentification enable per port, port closed for any traffic. When plugged device to dot1x port, switch waiting (It expects a period of time specified in the port configuration) EAPOL packet in from device. If EAPOL packet not received, switch study mac address device and used him as login/password for authentication. But I do not use such big timers.
In dot1x logs files no messages in it time.
