Step 1: Configure the Telnet user name and password on the Telnet Server through the
console port.
Note:
By default, the password is required for authenticating the Telnet user to log in the
switch. If a user logs in via the Telnet without password, he will see the prompt “Login
password has not been set !.”.

System View: return to User View with Ctrl+Z
[SW8800] user-interface vty 0
[SW8800-ui-vty0] set authentication password simple xxxx (xxxx is the preset login
password of Telnet user)
Step 2: The user logs in the Telnet Client (switch). For the login process, refer to the
section describing “Connecting a PC to the Switch through Telnet”.
Step 3: Perform the following operations on the Telnet Client:
<SW8800> telnet xxxx (xxxx can be the hostname or IP address of the Telnet Server. If it is the
hostname, you need to use the ip host command to specify.)
Step 4: Enter the preset login password and you will see the prompt such <SW8800>. If
the prompt “All user interfaces are used, please try later! The connection was closed by
the remote host!” appears, it indicates that the maximum number of Telnet users that
can be accessed to the switch is reached at this moment. In this case, please connect
later.
Step 5: Use the corresponding commands to configure the switch or view it running
state. Enter “?” to get the immediate help. For details of specific commands, refer to the
