The port configuration error caused the dot1x authentication vlan to fail

187 0 0 0


Check the configuration and find that when the port is enabled with 802.1x authentication:


Interface GigabitEthernet2/0/5

  Port link-type trunk


  Port trunk pvid vlan 20


  Port trunk allow-pass vlan 20

Authentication-profile dot1x


#


Authentication-profile dot1x


Info: To authorize VLANs for users, ensure that the interface type is hybrid.


 


Root cause

Link type configuration error


Solution

Change the port link type to hybrid


Suggestions and conclusions

In the unified mode and the traditional mode, 802.1x and mac authentication are configured. If the link type of the port is incorrect, there is a prompt. Need to be modified to hybrid or trunk type.
