Setting the Maximum Retransmission Times
The following commands are used for setting the maximum
authenticator-to-supplicant frame-retransmission times.
Perform the following configurations in system view.
By default, the max-retry-value is 3. That is, the switch can retransmit the
authentication request frame to a supplicant 3 times at most.
Setting the Handshake Period of 802.1x
The following commands are used to set the handshake period of 802.1x. After
setting the handshake-period, the system will send the handshake packets by the
period set. If the dot1x retry time is configured as N, the system considers the user
logged off and sets the user in logoff stat if it does not receive a response from the
user N times, consecutively.
Perform the following configurations in system view.
By default, the handshake period is 15 seconds.
