Note:
Some commands in this facility require updated GSR hardware. Please refer to the
Release Notes for details.
This chapter explains how to configure and use Access Control Lists (ACLs) on the GSR.
ACLs are lists of selection criteria for specific types of packets. When used in conjunction
with certain GSR functions, ACLs allow you to restrict Layer-3/4 traffic going through the
router.
This chapter contains the following sections:
•
“ACL Basics” on page 236
explains how ACLs are defined and how the GSR evaluates
them.
•
“Creating and Modifying ACLs” on page 240
describes how to edit ACLs, either
remotely or by using the GSR’s built-in ACL Editor function.
•
“Using ACLs” on page 242
describes the different kinds of ACLs: Interface ACLs,
Service ACLs, and Profile ACLs, and gives examples of their usage.
•
“Enabling ACL Logging” on page 249
explains how to log information about packets
that are permitted or denied because of an ACL.
•
“Monitoring ACLs” on page 250
lists the commands you can use to display
information about ACLs active on the GSR.
