2.8 Setting Passwords
The switch ships with a default of no enable password, which allows anyone on the network access to
various privilege levels. To prevent unauthorized changes to the switch’s configuration, you should set an
enable password for access to switch management. Follow the example below to assign a privileged
password.
Router> enable
Password: <no password by default; press Enter>
Router# configure terminal
Router(config)# enable password ?
0 Specifies an UNENCRYPTED password will follow
7 Specifies a HIDDEN password will follow
LINE The UNENCRYPTED (cleartext) 'enable' password
Router(config)# enable password 0 <password>
Router(config)# exit
Router# write [memory file]
A separate password should be set for the primary terminal line (console) and the virtual terminal lines
(telnet). The default password Asante is assigned only to the virtual terminal line Vty0. Up to three other
virtual terminal lines may be created, and they each will require a separate password.
Note: It is recommended that you change the default telnet password to prevent unauthorized access to the
switch.
