The procedures in this manual are for qualified service personnel.

Assigning permanent passwords

By default, the CLI is not protected by passwords. To secure CLI access, Dell strongly recommends assigning passwords. See the PowerConnect B-FCX Series Configuration Guide.

NOTE

You cannot assign a password using the Web Management Interface. You can assign passwords using Brocade Network Advisor if an enable password for a Super User has been configured on the device.

The CLI contains the following access levels:

User EXEC – The level you enter when you first start a CLI session. At this level, you can view some system information but you cannot configure system or port parameters.

Privileged EXEC – This level is also called the Enable level and can be secured by a password. You can perform tasks such as manage files on the flash module, save the system configuration to flash, and clear caches at this level.

CONFIG – The configuration level. This level lets you configure the system IP address and configure switching and routing features. To access the CONFIG mode, you must already be logged into the Privileged level of the EXEC mode.

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.
