SG 200-08: 802.1x not working with domain/hostname > 32 characters

Hi there,

we are facing a strange problem with a Cisco Small Business SG 200-08 Switch (firmware release 1.0.1.0). When configuring the switch to act as a RADIUS Client with 802.1x port security enabled, it sends the “Account Name” attribute to the radius server with max. 32 characters. The string comes in this format: host/dnsHostName and will be cut after 32 characters which will cause the NPS to say: “The specified domain does not exist.” – and NPS is right.

When I reduce the hostname so that host/dnsHostName <= 32 characters, authentication is working fine. And by the way, we also have a SG 200-26 in production and it can handle more than 32 characters which lead me to think of a bug in the firmware of the SG 200-08.

Does someone have any glues about this issue?

Thanks.
