Using Tools
Cisco Access Manager (CAM) provides a set of tools to help you to manage various features of your Cisco AccessPath system and System Controller. The tool set includes the several managers as described in the following sections:
•"Using the Template Manager" on page 5-1
•"Using the IOS Image Manager" on page 5-12
•"Using the Modem Firmware Image Manager" on page 5-30
•"Using the Configuration File Manager" on page 5-45
•"Using the Task Manager" on page 5-59
•"Using the User Account Manager" on page 5-67
Using the Template Manager
The Template Manager helps you to manage the CAM configuration templates. The Template Manager supports the following tasks:
•Importing a Configuration Template
•Editing a Configuration Template
•Deleting a Custom Configuration Template
The Template Manager lists all the available templates. The information displayed in the main Template Manager dialog box is independent of the device or container you might have selected in the Device Tree View. (See .)
Figure 8-1 Template Manager—Main Dialog Box
lists and briefly describes each of the fields that display on the main dialog box of the Template Manager.
Table 8-1 Template Manager Fields
CAM configuration templates are text files that contain Cisco IOS command-line interface (CLI) commands and template variables that allow you to easily define configuration data for a device. CAM creates your configuration files by substituting the template variables with data derived from selections or entries you made at the various dialog boxes during the create and modify procedures for System Controllers and shelves. CAM then downloads these configuration files to the devices that make up your Cisco AccessPath system.
You do not specify a configuration template for a stack. You specify a configuration template during the creation or modification of only System Controllers and shelves. You can also schedule when the download of the configuration is to occur. For details about the create and modify procedures, see the "Configuring System Controllers" section and the "Shelf Configuration for System Controllers" section.
Note You cannot edit and save template files from the GUI onto the database if the template file exceeds 28K bytes; the file will be truncated to 28K bytes. However, you can import template files that are larger than 28K bytes from UNIX.
CAM supports two types of templates:
•Default configuration templates—Read-only templates provided with CAM to generate most of the configurations for the supported Cisco AccessPath systems. In most cases, your selections or entries made during the create and modify procedures provide the information needed for CAM to customize these default templates and download the completed configuration files to the shelves on your Cisco AccessPath system. See for a complete list of CAM default configuration templates. See Appendix B, "," for complete versions of the default configuration templates provided in CAM.
•Custom configuration templates—Customer-created templates designed to add or change functionality built into the templates listed in CAM. You can create these templates by editing the default configuration templates and saving them with different file names. In most cases, the default configuration templates will meet your needs. However, if you have special requirements, consider creating a custom configuration template.
Note While you can create or modify a custom configuration template, you cannot create or modify the variables that come as part of the CAM default configuration templates. These variables are written in all capital letters and preceded by a pound sign (#). You can add or delete any CLI code, including CLI code that contains CAM variables, but you cannot edit these variables or create new ones.
All of the CLI code entered into a custom configuration template must be written in valid Cisco IOS syntax. Otherwise, when CAM attempts to download the configuration file, the shelf rejects the command.
Default Configuration Templates
lists the default configuration templates for each type of device.

Importing a Configuration Template
You can create a custom configuration template using the Import feature in the Template Manager.
To create a custom configuration template by importing:

Editing a Configuration Template
You can create a custom configuration template using the Edit feature in the Template Manager.
To edit a custom configuration template:
Figure 8-3 Template Manager—Edit Dialog Box
Deleting a Custom Configuration Template
You cannot delete a default configuration template. You can only delete custom configuration templates that you have either imported or renamed and edited. In addition, a custom template cannot be deleted if it is currently used by a shelf.
CautionIf you delete a custom configuration template, you cannot recover it.
To delete a custom configuration template:

Using the IOS Image Manager
The IOS Image Manager provides device-dependent management functions. The IOS Manager supports the following tasks:
•Setting the Default IOS Image
•Updating All to Default IOS Image
•Viewing the History of an IOS Image
The IOS Image Manager allows you to upgrade or restore a Cisco IOS image on a device. It checks the Cisco IOS images loaded on the shelves within a stack or System Controller. The IOS Image Manager compares the loaded version against the default image version. If the Cisco IOS images do not match, the IOS Image Manager reports the discrepancy.
CAM provides autoverify and autoupdate capability as options. For more information about these options, see the "Setting UI Preference" section.
The Cisco 3640, System Controller-3640, Cisco 7206, and Cisco AS5800 devices have two slots (slot0 and slot1) for Flash memory cards. CAM always uses slot0 as the default Flash memory device when loading Cisco IOS images to these devices. Be sure to have a Flash memory card inserted in slot0. Otherwise, CAM cannot successfully load the Cisco IOS image.

In addition to user-scheduled tasks, CAM supports 11 internal tasks, 3 ReportInternal tasks, and 8 OtherInternal tasks. CAM displays and executes tasks in chronological order, by their scheduled start time at the Task Manager dialog box. However, if user-scheduled tasks are scheduled to execute at the same time, CAM executes them one after the other in random sequence. If ReportInternal tasks, OtherInternal tasks, and user-scheduled tasks are scheduled to execute at the same time, CAM executes them simultaneously.

The User Account Manager helps you to manage CAM users. The User Account Manager supports the following tasks:
•Adding a user
•Modifying a user

The privileges defined at the User Account Manager dialog box determine the possible operations a user can do at the various CAM dialog boxes. The User Account Manager dialog box lists all users in addition to their respective passwords and privileges currently defined in CAM.
If you have administrator privileges, you can use all dialog boxes without restriction. You must have administrator privileges to use the User Account Manager. If you have administrator privileges, you can add, modify, and delete users at the User Account Manager dialog box. Additionally, you can set the user name, password, and read-write or read-only privileges for each CAM user.
If you have read-only or read-write privilege, you are restricted. The read-only privilege prevents you from creating or making changes at any of the dialog boxes in CAM. read-only users have access only to monitor and report dialog boxes. The read-write privilege limits a user to adding or editing his/her own settings. Read-write users have access to all dialog boxes except the User Account Manager dialog box.
If you do not have administrator privileges, the User Account Manager is not visible to you.
