Creating a New Service Class Template

---

Introduction

Up to this point, this document has explained how to configure the MGX 8850 using only the CLI. However, Service Class Templates can only be modified or created using the Cisco WAN Manager (CWM). The CWM is a Graphic User Interface (GUI) and must be purchased separately. This appendix explains how to use the CWM to create your own SCTs. Refer to the Cisco WAN Manager Operations Guide for detailed information on how to use the CWM.

---

Caution Only network engineers who are extremely knowledgeable about ATM and its parameters should create and use their own SCTs.

---

Creating a new SCT involves configuring the ATM parameters for specific classes of service to suit the special needs of your customers. For example, if you have customers with special policing or nonpolicing requirements, you can create an SCT to meet those specifications.

Some service providers offer different levels of service (such as gold, silver, or bronze) at different prices. Each level of service offers a different class of service and is supported by a different SCT.

Starting Cisco WAN Manager

Navigating the Service Class Template Manager

Figure D-7 shows the Service Class Template Manager. In the left column, under SCT File, the SCTs that are available on the card are listed. This view shows two SCTs:

•PORT : AXSM_EGR0[0]

•CARD : AXSM_ING[0]

PORT : AXSM_EGR0[0] is highlighted.

SCT parameters can be added or changed using either the SCT Tables or the SCT Entry Fields.

SCT Tables

The SCT Tables are the white rows and columns that appear in the upper half of the SCT Manager Window. The rows are the service types, and the columns are the parameters. Different parameter tables are displayed by selecting one of the different table tabs. The table tabs run horizontally through the middle of the SCT Manager. Figure D-7 shows the Policy Table tab selected.

To display different parameter tables, select one of the other tabs, such as Conn Parm or VC Threshold. For example, Figure D-8 shows the Service Class Template Manager with the VC Threshold tab selected.

Entry Fields

The Entry Fields appear in the gray, lower half of the SCT Manager Window. When you select a Service Type in the SCT Table, the name of the Service Type appears over the Entry Fields section and the CosB parameters for that Service Type appear in the Entry Fields.

Changing SCT Parameters

SCT Parameters can be modified using either a table or an entry field. The SCT tables contain all parameters, while the entry fields display only the most frequently accessed parameters.

Using the SCT Tables

To change an SCT parameter using the SCT Tables, select and highlight the field of the parameter you want to change by double-clicking on it. Once the field is selected you can either type a new number into the field or select a new value from a pull-down menu. Most fields have pull-down menus, but some require that the new value be typed.

Figure D-9 shows the SCT Manager with the number 257 in the Service Type field for RT VBR.1 selected. To change this value, type in a new value.

Figure D-10 shows the SCT Manager with the CAC Treatment field for RT VBR.1 selected and the pull-down menu displayed. To change this value, select a different value from the pull-down menu.

Using the Entry Fields

When you select a Service Type in the SCT Table, the name of the Service Type appears over the Entry Fields section and the CosB parameters for that Service Type appear in the Entry Fields.

The Entry Fields are divided into three columns:

•Rate and Priority

•Threshold

•Miscellaneous

Figure D-11 shows the SCT Manager with ABR.1 selected. ABR.1 - CosB #1 appears over the Entry Fields section. 100 in the Maximum Rate field of the Rate and Priority column is highlighted in blue.

To change a parameter in an entry field, select and highlight the field of the parameter you want to change by double-clicking on it. Then, type in the new value.

Verifying SCT Files are on the Switch

To verify that an SCT is properly stored on the switch, use the following procedure.

---

Step 1 Login to the switch and go to the C:SCT/AXSM directory.

Step 2 To get to the C:SCT/AXSM directory, type pwd (Present Working Directory) at the controller (PXM) prompt. This puts you at the C: directory.

pop20two.7.PXM.a > pwd 
C: 

Step 3 Change to the SCT directory by typing cd SCT.

pop20two.7.PXM.a > cd SCT 

Step 4 Change to the AXSM directory by typing cd AXSM.

pop20two.7.PXM.a > cd AXSM 

Step 5 Display the contents of the AXSM directory by typing ls or ll.

pop20two.7.PXM.a > ll 
size date time name

In the file system :  
total space : 819200 K bytes 
free space : 702351 K bytes 

Step 6 Verify that the name of the SCT you are looking for is in the list.
