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 a device operates as an authentication server, its authentication method for 802.1x users

cannot be configured as EAP.

z

Handshaking packets need the support of the H3C-proprietary client. They are used to test

whether or not a user is online.

z

As clients that are not of H3C do not support the online user handshaking function, switches cannot

receive handshaking acknowledgement packets from them in handshaking periods. To prevent

users 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.
