I’am configuring NAC on our switches and have created 802.1x rules for our AD PC’s and users.
We are testing this with 3 pc’s. The management access to the switch is based on AD (LDAP).
The ports of the switch are configured for 802.1.x and MAC authentication.
Now we experience that two pc’s lost the connection with the network. At that time I could not log in to the switch. 100% sure that I used the correct credintials.
In the end system events I noticed that the profile was changed form AD-user profile to the denny access profile.
After a while I can log in the switch an the pc got the access to the network back.
How can I troubleshoot this.
Switch: X440G2-48p-10G4 firmware version 188.8.131.52
