This chapter describes the procedure for creating and modifying AccessPath shelves in Cisco AccessPath Manager (APM).
Each AccessPath system is added to APM by first adding a stack, and then adding all of the shelves (access servers, routers, and switches) that make up that stack. After you have finished adding each shelf, you can have APM download to that shelf the configuration file based on your choices in the shelf creation process.
You can modify stacks and shelves to accommodate changes you make in your AccessPath system or its network connections using procedures similar to those you used to create the stacks and shelves. Additionally, APM allows you to view, delete, or restore these shelves.
Cisco APM allows you to configure AccessPath shelves in the following ways:
To add a shelf to a stack or modify a shelf in a stack, follow these steps.
 | Caution When you add, modify, or restore a shelf and download the configuration to the shelf, the previous configuration file on that shelf will be erased and overwritten by the configuration based on configuration template you select. |
Step 1 Start the Shelf Add or Shelf Modify procedure.
(a) Click the name of the stack you want to add a shelf to.
(b) Click Configure.
(c) Click Shelf Add or Shelf Modify.
(d) Click Execute.
The first Shelf Global Information screen will appear. (See Figure 4-1.)
Step 2 Enter your configuration information in the screens as they appear. Click Next between screens.
Detailed procedures for adding or modifying shelves are found in the following sections. (The Shelf Add and Shelf Modify procedures are virtually identical, but the examples will use the Shelf Add procedure and screens.) The steps are as follows:
(a) "Configure Shelf Global Information"
(b) "Configure the Shelf Trunk Interface (Cisco AS5200 and Cisco AS5300 Shelves Only)"
(c) "Configure the Shelf Addresses"
You must supply information for all fields presented in bold in each dialog box. (Note that pull-down menus will be disabled if your previous stack or shelf configuration choices make them unnecessary.)
Configure the information in the Shelf Global Information screen (see Figure 4-1) as the first step in either the Shelf Add or Shelf Modify procedure. (See Table 4-1 for a detailed procedure for configuring this information.)
| Step | Description | ||
|---|---|---|---|
| This description of the shelf is for your convenience. | ||
| The serial number of the shelf. | ||
| Select a device type. The device types displayed in this menu depend on two things:
| ||
| The shelf number is a unique identifier of the shelf telling where it is located in the stack.
This pull-down menu displays only the shelf numbers that are available for the device type you are adding and depends on the stack type and the shelves that you might have already added to the stack. Note When configuring the first Access Server Shelf in an AccessPath-TS3 with a Catalyst 5000 switch (as opposed to a Catalyst 5002 switch or no standalone switch), skip Shelf 5 and select Shelf 6. (See Figure 4-2.) | ||
| A case-sensitive unique name for the shelf. The default host name contains the stack ID, the device type, and the shelf number. For example, s5AS01 would be the first Access Server shelf in a stack with the stack ID s5. | ||
| When APM enters the enable mode, if the secret password was preconfigured to the device, then it will prompt APM for the original secret password. Note If the device is configured for an original line password and you do not enter one here, or enter an incorrect password, the shelf configuration will fail. | ||
| When APM Telnets into the device, if the line password was preconfigured to the device, then it will prompt APM for the original line password. Note If the device is configured for an original line password and you do not enter one here, or enter an incorrect password, the shelf configuration will fail. | ||

Configuring the Shelf Trunk Interface is the second step in either the Shelf Add or Shelf Modify procedure for Cisco AS5200 and Cisco AS5300 shelves only. (See Figure 4-3 and Table 4-2 for instructions.)
| Step | Description | ||
|---|---|---|---|
| Type of transmission unit used in the T1 or E1 link. Available choices for Channelized E1 include:
Available choices for Channelized T1 and PRI include:
| ||
| Variety of Zero Code Suppression used on the link, which in turn affects a number of its characteristics. Available choices for Channelized E1 include:
Available choices for PRI and Channelized T1 include:
| ||
| Trunk type of the shelf. Valid selections (which will be limited depending on the configuration of the stack) include:
| ||
| ISDN switch type that services your T1 or E1 PRI lines. You should obtain the correct switch type from your ISDN service provider (telco). Available choices include:
| ||
| The Cisco AS5200 and Cisco AS5300 support Channel Associated Signaling for channelized T1/E1 lines. Typically all channels of a channelized T1 or E1 line are used for analog calls. However, the Cisco AS5200 and Cisco AS5300 require a signal converter to perform conversions between R2 signaling and ear and mouth (E&M) signaling. The Cisco AS5200 supports E&M signaling on its T1/E1 controllers. Valid selections for Channelized E1 include:
Valid selections for Channelized T1 include:
| ||
| If you have selected E1 R2 signalling, you may need to select a country customization for this signalling. The options include:
| ||
| Select Yes or No depending on whether this shelf will be using multiple B channels. | ||
| Select Yes or No to enable or disable Virtual Private Dialup Network (VPDN) support. | ||
| Depending on the type of shelf you are configuring, proceed as follows: |
| 1ISDN = Integrated Services Digital Network. 2CAS = Channel Associated Signalling. |
The Shelf Address screens, which make up the third step in either the Shelf Add or the Shelf Modify procedure, vary depending on the shelf you are adding or modifying. Use the appropriate procedure for your shelf.

Scheduling the shelf configuration is the fifth and final step in either the Shelf Add or Shelf Modify procedure. (See Figure 4-6 and Table 4-9.)
| Step | Description | ||
|---|---|---|---|
| When doing a Shelf Add or Shelf Modify, you can have the configurations downloaded to the shelf now or later. | ||
| If you chose to download the configuration job later, use these fields to schedule the job. The download will occur when the server time matches the time you configure.
| ||
| Clicking Finish will start or schedule the downloading of the configuration file. |
 | Tips |
If your configuration fails:
1. Verify that any passwords you entered on the configuration screens are the correct ones for the shelf.
2. Verify that there is physical connectivity to the shelf.
3. Verify the IP address that you have configured for the configuration download by connecting to that port using Telnet. (You configured this IP address in Step 2 of Table 4-8.)
4. Try rescheduling the configuration. The console port might have been busy when APM attempted the download.
Use this procedure to view a shelf. You cannot use the Shelf View feature to change the value of any field. If you need to modify a shelf, see the section "Adding or Modifying a Shelf".
Step 1 Select the shelf you want to view by clicking on its name.
Step 2 Click Configure.
Step 3 Click Shelf View.
Step 4 Click Execute.
Step 5 Click Next to move through the screens. For an explanation of the data fields in these screens, refer to the section "Adding or Modifying a Shelf".
Use the following procedure to delete a shelf.
| Caution When a shelf is deleted, all related information about the shelf will be deleted from the database. Only use this procedure if you are sure you want to delete the shelf and its historical data. |
Step 1 Select the shelf you want to delete by clicking on its name.
Step 2 Click Configure.
Step 3 Click Shelf Delete.
Step 4 Click Execute.
Step 5 Click Next to move through the four screens that show the configuration of the shelf you want to delete. For an explanation of the data fields in these screens, refer to "Adding or Modifying a Shelf".
Step 6 If this is the correct shelf, and you are sure you want to delete it and all of its historical data, click Delete. Otherwise, click Cancel.
Use the following Restore Shelf procedure if you have replaced a physical device and want to use an existing configuration for the new device:
Step 1 Select the shelf you want to restore by clicking on its name.
Step 2 Click Configure.
Step 3 Click Shelf Restore.
Step 4 Click Execute.
