H3C S5100-SI

z 802.1x configurations take effect only after you enable 802.1x both globally and for
specified ports.
z The settings of 802.1x and MAC address learning limit are mutually exclusive.
Enabling 802.1x on a port will prevent you from setting the limit on MAC address
learning on the port and vice versa.
z The settings of 802.1x and aggregation group member are mutually exclusive.
Enabling 802.1x on a port will prevent you from adding the port to an aggregation group
and vice versa.
z When a device operates as an authentication server, its authentication method for
802.1x users cannot be configured as EAP.
z With the support of the H3C proprietary client, handshake packets 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 handshake 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 The handshake packet protection function requires the cooperation of the client and
the authentication server. If either of the two ends does not support the function, you
need to disable it on the other one.
