Configuring the basic access function
An S7500E switch without any configuration can perform basic data transmission immediately after it is
connected to a network. To implement more service requirements, configure the basic network settings
in Table 12 on the switch.

Configuration example
Configuring Telnet service
# Enter system view.
<Sysname> system-view
# Enable the Telnet server.
[Sysname] telnet server enable
# Enter user interface view of VTY 0.
[Sysname] user-interface vty 0
# Configure the authentication mode as password for users logging in through user interface VTY 0.
[Sysname-ui-vty0] authentication-mode password
# Configure the password as hello.
[Sysname-ui-vty0] set authentication password cipher hello
# Set the user privilege level to 3 so all Telnet users access VTY 0 can use all commands.
[Sysname-ui-vty0] user privilege level 3
[Sysname-ui-vty0] quit
