z 802.1x configurations take effect only after you enable 802.1x both globally and for specified ports.
z If you enable 802.1x for a port, you cannot set the maximum number of MAC addresses that can be
learnt for the port. Meanwhile, if you set the maximum number of MAC addresses that can be learnt
for a port, it is prohibited to enable 802.1x for the port.
z If you enable 802.1x for a port, it is not available to add the port to an aggregation group.
Meanwhile, if a port has been added to an aggregation group, it is prohibited to enable 802.1x for
the port.
z Changing the access control method on a port by the dot1x port-method command will forcibly
log out the online 802.1x users on the port.
z When the device itself operates as an authentication server, its authentication method for 802.1x
users cannot be configured as EAP.
z Handshaking packets are used to test whether a user is online or not. Users need to run the
proprietary iNode client software to respond to the handshaking packets.
z As clients not running the iNode client software do not support the online user handshaking
function, the device cannot receive handshaking acknowledgement packets from the client in
handshaking periods. To prevent the user being falsely considered offline, you need to disable the
online user handshaking function in this case.
z For the handshaking packet secure function to take effect, the clients that enable the function need
to cooperate with the authentication server. If either the clients or the authentication server does
not support the function, disabling the handshaking packet secure function is needed.

By default, the maximum retry times
to send a request packet is 2. That
is, the authenticator system sends a
request packet to a supplicant
system for up to two times by
default.
