Note:
Some commands in this facility require updated SSR hardware. Please refer to the
Release Notes for details.
This chapter explains how to configure and use Access Control Lists (ACLs) on the SSR.
ACLs are lists of selection criteria for specific types of packets. When used in conjunction
with certain SSR functions, ACLs allow you to restrict Layer-3/4 traffic going through the
router.
This chapter contains the following sections:
• “ACL Basics” on page 256 explains how ACLs are defined and how the SSR evaluates
them.
• “Creating and Modifying ACLs” on page 260 describes how to edit ACLs, either
remotely or by using the the SSR’s built-in ACL Editor function.
• “Using ACLs” on page 262 describes the different kinds of ACLs: Interface ACLs,
Service ACLs, and Profile ACLs, and gives examples of their usage.
• “Enabling ACL Logging” on page 268 explains how to log information about packets
that are permitted or denied because of an ACL.
• “Monitoring ACLs” on page 269 lists the commands you can use to display
information about ACLs active on the SSR.
