Foundry FastIron LS Layer 2 Compact Switch Hardware Installation Guide

You can set the following levels of Enable passwords:

•Super User – Allows complete read-and-write access to the system. This is generally for system administrators and is the only password level that allows you to configure passwords.

NOTE: You must set a super user password before you can set other types of passwords.

•Port Configuration – Allows read-and-write access for specific ports but not for global (system-wide) parameters.

•Read Only – Allows access to the Privileged EXEC mode and CONFIG mode but only with read access. To set passwords:

1.At the opening CLI prompt, enter the following command to change to the Privileged level of the EXEC mode:

FLS648 Switch> enable

2.Access the CONFIG level of the CLI by entering the following command:

FLS648 Switch# configure terminal FLS648 Switch(config)#

3.Enter the following command to set the super-user password:

FLS648 Switch(config)# enable super-user-password <text>

NOTE: You must set the super-user password before you can set other types of passwords.

4.Enter the following commands to set the port configuration and read-only passwords:

FLS648 Switch(config)# enable port-config-password <text> FLS648 Switch(config)# enable read-only-password <text>

NOTE: If you forget your super-user password, see “Recovering from a Lost Password” on page 4-2.

Syntax: enable super-user-password read-only-password port-config-password <text> Passwords can be up to 32 characters long.

Recovering from a Lost Password

By default, the CLI does not require passwords. However, if someone has configured a password for the device but the password has been lost, you can regain super-user access to the device using the following procedure.

NOTE: Recovery from a lost password requires direct access to the serial port and a system reset.

To recover from a lost password:

1.Start a CLI session over the serial interface to the Foundry device.

2.Reboot the device.

3.While the system is booting, before the initial system prompt appears, enter b to enter the boot monitor mode.

4.Enter no password at the prompt. (You cannot abbreviate this command.)

5.Enter boot system flash primary at the prompt. This command causes the device to bypass the system password check.

After the console prompt reappears, assign a new password.
