Hi,
Since few months, I working to deploy the security protocol 802.1x on wired network of enterprise. It's work well, but since two weeks one of our switches is not more able to authenticate users.
It's a DELL PowerConnect 5548p - firmware version 4.1.0.20
I get the same message in logs for every try:
Warning %SEC-W-SUPPLICANTUNAUTHORIZED: MAC **** was rejected on port gi*** because Radius API returned error (e.g. No Radius server is configured)
Whereas the radius server are configured, there can ping and servers are ok: there works well with other switches
show radius-servers

Deadtime : 10

I try to remove then re-add servers or reboot switches: not better.
Do you have any idea ?
