The last two days, I have supported a customer during the implementation of 802.1x. His network consisted of HPE/ Aruba and some HPE Comware switches. Two RADIUS server with appropriate policies was already in place. The configuration and test with the ProVision based switches was pretty simple. The Comware based switches, in this case OfficeConnect 1920, made me more headache.
The customer had already mac authentication running, so all I had to do, was to enable 802.1x on the desired ports of the OfficeConnect 1920. The laptop, which I used to test the connection, was already configured and worked flawless if I plugged it into a 802.1x enabled port on a ProVision based switch. The OfficeConnect 1920 simply wrote a failure to its log and the authentication failed. The RADIUS server does not logged any failure, so I was quite sure, that the switch caused the problem.
DOT1X/6/DOT1X_AUTH_FAILURE: -IfName=GigabitEthernet1/0/1-UserName=DOM\USERNAME; DOT1X authentication failed
After double-checking all settings using the web interface of the switch, I used the CLI to check some more settings. Unfortunately, the OfficeConnect 1920 is a smart-managed switch and provides only a very, very limited CLI. Fortunately, there is a developer access, enabling the full Comware CLI. You can enable the full CLI by entering
after logging into the limited CLI. You can find the password using your favorite internet search engine. ;)
While poking around in the CLI, I stumbled over this option, which is entered in the interface context:
[1920-GigabitEthernet1/0/1] dot1x mandatory-domain RADIUS
RADIUS is the authentication domain, which was used on this switch. The command specifies, that the authentication domain RADIUS has to be for 802.1x authentication requests. Otherwise the switch would use the default authentication domain SYSTEM, which causes, that the switch tries to authenticate the user against the local user database.
I have not found any way to specify this setting using the web GUI! If you know how, of if you can provide additional information about this “issue”, please leave a comment.
