Configuring Network Security with ACLs
This chapter describes how to configure network security on the Catalyst 3750-X or 3560-X switch by
using access control lists (ACLs), which in commands and tables are also referred to as access
lists.Unless otherwise noted, the term switch refers to a Catalyst 3750-X or 3560-X standalone switch
and to a Catalyst 3750-X switch stack.
Note Information in this chapter about IP ACLs is specific to IP Version 4 (IPv4). For information about IPv6
ACLs, see Chapter 1, “Configuring IPv6 ACLs.”
For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release, see the “Configuring IP Services” section in the “IP Addressing and Services”
chapter of the Cisco IOS IP Configuration Guide, Release 12.4, and the Cisco IOS IP Command
Reference, Volume 1 of 3: Addressing and Services, Release 12.4.
Catalyst 3750-X and 3560-X switches running the IP base or IP services feature set also support Cisco
TrustSec Security Group Tag (SCT) Exchange Protocol (SXP). This feature supports security group
access control lists (SGACLs), which define ACL policies for a group of devices instead of an IP
address. The SXP control protocol allows tagging packets with SCTs without a hardware upgrade, and
runs between access layer devices at the Cisco TrustSec domain edge and distribution layer devices
within the Cisco TrustSec domain. Catalyst 3750-X and 3560-X switches operate as access layer
switches in the Cisco TrustSec network.
For more information about Cisco TrustSec, see the “Cisco TrustSec Switch Configuration Guide” at this
URL:

The sections on SXP define the capabilities supported on the Catalyst 3750-X and 3560-X switches.
Note On switches running the LAN base feature set, router ACLs are supported only on switch virtual
interfaces (SVIs). VLAN maps are not supported.
