4.2.28 Configuring the Option
Flag for EAPOL Frames to
Carry TAG
In accordance with IEEE 802.1x, the EAPOL packets cannot be added with vlan TAG. However,
based on the possible application requirements, the selection flag is provided. When the flag is
turned on, tags can be outputted according to the related output rule of the trunk ports.
The typical application environment is to enable 802.1x authentication on the convergence
layer. For more information, see “Topologies of Typical Applications”.
In the privileged mode, you can configure the flag for EAPOL frames to carry TAG by
performing the following steps:
Command Function
configure terminal
Enter the global configuration mode.
dot1x eapol-tag
Enable the flag for EAPOL frames to carry TAG. By
default, the function is disabled.
end
Return to the privileged mode.
write
Save the configuration.
show dot1x
Show the configuration.
You can disable this function by using the no dot1x eapol-tag command.
