The port configuration error caused the dot1x authentication vlan to fail

205 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


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.
