Troubleshooting
Why doesn’t the IP phone pass 802.1X authentication?

b)
Check if the device is authenticated successfully, and an IP address is assigned to it. If

EAP-PEAP/MSCHAPv2, EAP-TTLS/EAP-MSCHAPv2, EAP-PEAP/GTC, EAP-TTLS/EAP-GTC and
EAP-FAST protocols are used, ensure that the certificate uploaded to the phone is valid.
a)
Double click the certificate to check the validity time.
b)
Check if the time and date on the phone is within the validity time of the uploaded
certificate. If not, re-generate a certificate and upload it the phone.
Ensure that the failure is not caused by network settings.
a)
Disable LLDP feature and manually configure a VLAN ID for the Internet port of the
phone to check if the authentication is successful. If the phone is authenticated
