Setting passwords
32
1. Start a CLI session over the serial interface to the device.
2. Reboot the device.
3. At the initial boot prompt at system startup, enter b to enter the boot monitor mode.
4. Enter no password at the prompt. (You cannot abbreviate this command.) This command will
cause the device to bypass the system password check.
5. Enter boot system flash primary at the prompt.
6. After the console prompt reappears, assign a new password.
Displaying the SNMP community string
If you want to display the SNMP community string, enter the following commands.
PowerConnect(config)#enable password-display
PowerConnect#show snmp server
The enable password-display command enables display of the community string, but only in the
output of the show snmp server command. Display of the string is still encrypted in the
startup-config file and running-config. Enter the command at the global CONFIG level of the CLI.
Disabling password encryption
When you configure a password, then save the configuration to the flash memory on the Dell
PowerConnect device, the password is also saved to flash as part of the configuration file. By
default, the passwords are encrypted so that the passwords cannot be observed by another user
who displays the configuration file. Even if someone observes the file while it is being transmitted
over TFTP, the password is encrypted.
NOTE
You cannot disable password encryption using the Web Management Interface.
If you want to remove the password encryption, you can disable encryption by entering the following
command.
PowerConnect(config)#no service password-encryption
Syntax: [no] service password-encryption
NOTE
The no service password-encryption command will not work if service password-encryption was
configured previously by default. In this case, enter no service password-encryption then create a
username and password.
Specifying a minimum password length
By default, the Dell PowerConnect device imposes no minimum length on the Line (Telnet), Enable,
or Local passwords. You can configure the device to require that Line, Enable, and Local passwords
be at least a specified length.
For example, to specify that the Line, Enable, and Local passwords be at least 8 characters, enter
the following command.
