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 the switch itself operates as an authentication server, its authentication method for 802.1x 
users cannot be configured as EAP. 
z  Handshake packets are used to test whether a user is online or not. Users need to run the 
proprietary client software of H3C to respond to the handshake packets. 
z  As clients not running the H3C client software 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.

By default, a port can 
accommodate up to 256 users at 
a time. 
Set the maximum retry times

dot1x retry max-retry-value 
Optional 
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.
