ATM Features for the LightStream Switch

This chapter provides procedures for using CiscoView to perform Asynchronous Transfer Mode (ATM) configuration on LightStream switches. For ATM LANE configuration information for Catalyst switches, refer to Chapter 5, "ATM LANE Configuration for Catalyst Switches."

ATM features for the LightStream switches are described in the following sections, which contain a variety of features used for ATM configuration (Figure 6-1):

Managing ATM Device Features

The ATM device features allow access to the following features:

To invoke the ATM Feature application, select ATM Features from the menu bar.

Within each ATM device feature, change the category to access different management features.

To display the information for any category, select the appropriate category from the pull-down menu by the side of the CATEGORY label.

Note Where windows display "optional" fields, you can either enter a value or leave the field blank so the device automatically generates the value.

Note For additional information regarding the fields within the windows, click Help to access the CiscoView Help screens.

Resource Management (Global)

The Resource Management (Global) category allows you to provide management of critical resources in an ATM network, such as buffer space and trunk bandwidth. When the Resource Management (Global) category is selected, the default window displayed is the ATM RM Switch Configuration window.

Subcategories available including the following:

ATM RM Switch Configuratio n

If you select the ATM RM Switch Configuration category, the ATM RM Switch Configuration window opens. The ATM RM Switch Configuration window (Figure 6-2) allows you to display or modify available bit rate (ABR) and unspecified bit rate (UBR) configuration information. To modify the current configuration, edit the field(s) and click Modify to commit the modification. If an invalid value is entered, an error message is displayed. (See "Hints for Modifying the ATM RM Switch Configuration" for more information.)

Hints for M odifying the ATM RM Switch Configuration

When modifying the fields, consider the following:

When setting the Set the Over-Subscription Factor field, in general, the larger the Over-Subscription Factor value, the larger the queue size.
When setting the ABR Mode field, consider the following:
- relative rate sets the congestion notification to be received from outside the switch.
- EFCI sets the congestion notification in the headers of forward cells, which are turned around at the destination end system and sent back to the source end system.
- both sets the congestion notification to both the relative rate and EFCI congestion notification types for ABR connections.
The default value is 1% for the Set the Sustained Cell Rate Margin Factor field.

ATM RM Queue
