| The root cause is that the SSID tpmpad that uses MAC address authentication is configured on the AC with local database. After the terminal is connected to this SSID, the terminal will remember it. After the terminal is locked and unlocked, the terminal connects to this SSID. But if the terminal does not have a local account, the authentication fails. After the authentication fails, the terminal will be silent for 60 seconds. In this case, the terminal cannot perform MAC address-prioritized Portal authentication. # interface Wlan-Ess100 port hybrid pvid vlan 100 port hybrid untagged vlan 100 mac-authen permit-domain name test force-domain name test mac-authen username macaddress format with-hyphen password cipher %@%@_MK_U"UQ|S{:|5#m4M-QSjmJ%@%@ # [AC6605]dis mac-authen MAC address authentication is Enabled.
