  The user fails to ping 192.168.32.120 before authentication. 
  The user connects to the NAS, the authentication succeeds, and the user can successfully ping 
192.168.32.120. 
  Information of the authenticated user is displayed.

Common Errors 
  The MAC account format is incorrect on the authentication server. 
4.4.4  Configuring Extended Functions 
Configuration Effect 
  The multi-account function allows a user to switch its account upon re-authentication. In special scenarios such as 
Windows domain  authentication, multiple authentications  are  required  to  access  the  domain  and  the  user  account 
changes during authentication. This function applies to these scenarios. 
  802.1X allows users to obtain IP addresses before accounting. In this manner, the IP address is carried during user 
accounting, meeting service requirements. After a user is authenticated and goes online, the NAS can obtain the IP 
address of the user from the supplicant or through DHCP snooping, and then 802.1X server initiates an accounting 
request. To avoid the case in which the NAS does not initiate accounting for a long time due to failure to obtain the IP 
address of the authentication client, configure the IP detection timeout for this function. If the NAS does not obtain the 
IP address of the user within the configured time (5 minutes by default), it forces the user offline. 
  802.1X allows users to switch to the preset bypass WLAN when the RADIUS server is inaccessible. Survival WLANs 
are  generally  in  OPEN  mode  and  their  services  are  unavailable  by  default.  If  802.1X-based  WLAN  services  are 
unavailable, enable this WLAN and disable WLAN-based 802.1X authentication so that users can switch to the bypass 
WLAN to properly access the network. 
  802.1X can be used with Web authentication. If Web authentication is enabled on an 802.1X-enabled WLAN, users 
perform 802.1X authentication only for encryption purposes. To access the network, they should also perform Web 
authentication. In this case, all air interface data of users is encrypted, enhancing security of user data. 
  802.1X provides prompts on syslog printing of user online/offline. You can adjust the online/offline syslog printing rate 
based on the user authentication rate to prevent high CPU utilization due to frequent syslog printing for a large number 
of users going online/offline.
