Configuring authentication on a user interface
You can configure authentication on a user interface to control access to the switch.
Table 7 describes the Telnet login authentication methods available for a VTY user interface.
Table 7 Telnet login authentication methods
Authentication method Feature Application scenarios
None
Easy to configure, allows any user to Telnet to
your switch, and lowest in security Lab environments and extremely
secure network environments
Password
Easy to configure, secure, and flat user
management Environments that do not need
granular privilege management
Username and password
Complex to configure, secure, and
hierarchical user management
Environments where multiple
operators cooperate to manage
the switch

Guide.
Configuring the basic access function
An S10500 switch without any configuration can perform basic data forwarding immediately after it is
plugged into a network. To implement more forwarding features, configure the basic network settings
in Table 8 on the switch.
Table 8 Basic network settings
Setting Description
IP address Enables remote switch management, for example, by using Telnet.
Static routes Implement static routing.
VLANs Divide the LAN into multiple VLANs for data security.
MSTP Avoids loops in a dual-homed network.
For more information about these features, see H3C S10500 Switch Series Configuration Guides.
