We configured 802.1x for the wired network. Some pc's and printers do not work. This is the message on the switch:
DOT1X-5-FAIL: Authentication failed for client (Unknown MAC)on interface fa0/1
All pc's work with digital certificates and EAP-TLS on the switches.
I don't understand why the switch doesn't see the real MAC address of the connected host.
Any idea's ?
