224 CHAPTER 17: 802.1X CONFIGURATION
c
CAUTION:
■ 802.1x configurations take effect only after you enable 802.1x both globally
and for specified ports.
■ 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.
■ 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.
■ 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.
■ When a device operates as an authentication server, its authentication method
for 802.1x users cannot be configured as EAP.
■ Handshaking packets need the support of the 3Com-proprietary client. They
are used to test whether or not a user is online.
■ As clients that are not of 3Com do not support the online user handshaking
function, switches cannot receive handshaking acknowledgement packets
