freeradius confuses switch

Hello,

In tcpdump I see the radius packets in the following order:

switch -> freeradius: access-request (1), id: 0x2d
freeradius -> switch: access-reject (3), id: 0x2d
freeradius -> switch: access-accept (2), id: 0x2c

In the last packet the switch receives all proper vlan attributes.

In the tplink switch CLI I see it does *not* change the port state from unauthorized to authorized.

Upgrading the switch to latest firmware did not change anything.

I am not sure is the switch working correctly because of the access-reject package?


Regards,

Christoph
