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

•Managing ATM Device Features

•Managing ATM Port Features

Figure 6-1

ATM Features

Managing ATM Device Features

The ATM device features allow access to the following features:

•Resource Management (Global)

•ATM OAM

•ATM RMON

•ATM Accounting

•ATM Signaling (Global)

•ATM Signaling Diagnosis

•PNNI (Global)

•ILMI (Global)

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.
