Chapter3 Getting Started with CMS
Understanding CMS
Guide mode is not available if your switch access level is read-only. For more information about the
read-only access mode, see the “Privilege Levels” section on page 3-6.

Expert Mode

Expert mode is for users who prefer to display all the parameter fields of a feature in a single
CMS window. You can view information about the parameter fields by clicking the Help button.
If you select Expert Mode but you want to use Guide Mode instead, you must click Guide before
selecting an option from the menu bar, tool bar, or popup menu. If you change the interaction mode after
selecting a configuration option, the mode change does not take effect until you select another
configuration option.

Wizards

Similar to guide mode, wizards provide a step-by-step ap p ro ac h fo r co mp le tin g a s p eci fic configuration
task. Unlike guide mode, a wizard does not prompt you to provide information for all of the feature
options. Instead, it prompts you to provide minimal information and then uses the default settings of the
remaining options to set up default configurations.
When you select a feature that has Wizard in the name, the wizard l aunches for that feature, as shown in
Figure3-3 on page 3-5.
Wizards are not available for all features or for read-only access levels. For more information about the
read-only access mode, see the “Privilege Levels” section on page 3-6.
Privilege Levels
CMS provides two levels of access to the configuration options: read-write ac cess and r ead-only access.
If you know your privilege level, you must specify it in the URL that you use to access the cluster. For
example, if your privilege level is 13, enter this URL:
http://ip_address/level/13
Privilege levels 0 to 15 are supported.
•Privilege level 15 provides read-write access to CMS. This is the default.
•Privilege levels 1 to 14 provide read-only access to CMS. Any options in the CMS windows, menu
bar, toolbar, and popup menus that change the switch or cluster configuration are not shown in
read-only mode.
•Privilege level 0 denies access to CMS.
If you do not specify a privilege level when you access CMS, the switch verifies whether you have
privilege level 15. If you do not, you are denied access to CMS. If you do have privilege level 15, you
are granted read-write access. Therefore, you do not need to include the privilege level if it is 15.
Entering zero denies access to CMS.
For more information about privilege levels, see the “Preventing Unauthorized Access to Your Switch”
section on page 7-1 and the “Configuring Multiple Privilege Levels” section on page 7-7.
