Cisco Catalyst 6500 next generation

hardware—Sup720 and 6700 Series

line cards.

This DG is based on lab testing using

the Sup720 and 6700 Series line

cards in the Cisco Catalyst 6500

platform in core, aggregation, and

access layer switches.

Native 12.2.18 SXD3 was used

in the lab environment.

OL-11568-01

What is Included in this DG Release?

Application Control Engine (ACE) The ACE module introduces a next

generation load balancer and security

services module that permits higher

performance and active-active

designs. The ACE module is not an

available product at the time of this

writing.

Firewall Services Module (FWSM)

Release 3.1

Release 3.1 of the FWSM software

introduces several new capabilities

including Private VLAN support and

active-standby context groups, which

permit load balancing of contexts

across an FWSM redundant pair.

Release 3.1 is not available at the

time of this writing.
