Using Access Control

This chapter describes how to configure and maintain access control lists, which are used to permit or

deny incoming calls or outgoing calls on an interface of the ATM switch router.

This chapter provides advanced configuration instructions for the Catalyst 8540 MSR,

Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the

commands mentioned in this chapter, refer to the ATM Switch Router Command Reference publication.

This chapter includes the following sections:

Access Control Overview

The ATM signalling software uses the access control list to filter setup messages on an interface based

on destination, source, or a combination of both. Access lists can be used to deny connections known to

be security risks and permit all other connections, or to permit only those connections considered

acceptable and deny all the rest. For firewall implementation, denying access to security risks offers

more control.
