Command Usage
â—† When this device is functioning as intermediate node in the network and does
not need to perform dot1x authentication, the dot1x eapol pass-through
command can be used to forward EAPOL frames from other switches on to the
authentication servers, thereby allowing the authentication process to still be
carried out by switches located on the edge of the network.
â—† When this device is functioning as an edge switch but does not require any
attached clients to be authenticated, the no dot1x eapol-pass-through
command can be used to discard unnecessary EAPOL traffic.
dot1x timeout held-period Sets the time a port waits after the maximum start count
has been exceeded before attempting to find another
authenticator
IC
