Setting the Telnet password
To require password authentication when the user logs into the switch
through the Telnet protocol, you must edit the Telnet password. Select
Administration > Security > Telnet from the main menu and perform the
following procedure.
Step
Action
1
Select the password type from the Telnet Switch Password Type
list. Three options are available in the Telnet Switch Password
Type list:
•
None
Users who access the switch through the Telnet protocol require
no password.
CAUTION
Using None means that any user who knows the IP
address of the switch and the appropriate network
access can change the switch configuration.
•
Local Password
The user must enter a password that determines their individual
access rights. These passwords are configured in Steps 2 and 3
of this procedure. These passwords must be 1 to 15 characters
in length.
•
RADIUS Authentication
A RADIUS server on the local area network authenticates
the user. For information about configuring the parameters
for RADIUS server authentication, see
.
2
If you selected the Local Password option in Step 1, specify a
password to grant read-only access to the switch in the Read-Only
Telnet Password field.
3
If you selected the Local Password option in Step 1, specify a
password to grant read/write access to the switch in the Read/Write
Telnet Password field.
Note: A value of None or RADIUS Authentication in the Telnet
Switch Password Type list always overrides the values in the
Read-Only Telnet Password and Read/Write Telnet Password
fields.
