z  Configure the authentication scheme 
Configure the authentication server by referring to related parts in AAA in the Security Configuration 
Guide.  
To ensure successful login, change the settings of the terminal emulation program running on the PC, 
as shown in 
Figure 14-4, to make them consistent with those on the AP. 
Logging In Through Telnet 
You can telnet to a remote AP to manage and maintain the AP. To achieve this, configure both the AP 
and the Telnet terminal. 
Table 14-5 Telnet login configuration requirements 
Item  Requirement 
Start the Telnet Server (Telnet server is enabled by default). 
The IP address of the VLAN interface of the AP is configured and the AP and the Telnet 
terminal can reach each other. 
AP 
The authentication mode and other settings are configured. See 
Table 14-6 and Table 
14-7. 
Telnet is running. 
Telnet terminal 
The IP address of the management VLAN interface of the AP is available. 
 
Establishing a Telnet Connection 
 Use a PC as the telnet client to telnet to an AP and configure it. 
Step1  Configure the IP address of VLAN-interface 1 through the console port (VLAN 1 is the default VLAN of 
the AP). 
z  Set up a configuration environment as shown in Figure 14-9. Connect the serial port of the PC (or 
terminal) to the console port of the AP through a console cable.
