Cisco IOS Software for the Cisco Catalyst 6500 Series
Cisco IOS Software for the Cisco Catalyst 6500 Series supervisor engines requires the MSFC on the supervisor
engine. It provides integrated multilayer functions in a single image and is optimized for core, distribution, Internet
access, and data center deployments. Cisco IOS Software combined with the performance of the Cisco Catalyst 6500
Series offers the necessary features for a high-performance Layer 3-enabled deployment, including support
for a distributed architecture with the ability to scale the switch to 400 Mpps throughput. Additionally, Cisco IOS
Software provides operational ease of use by offering a single image and configuration file to be deployed across
the Cisco Catalyst 6500 Series switches.
Cisco Catalyst Operating System Software with Optional Cisco IOS Software on the MSFC
Cisco Catalyst Operating System Software is the premier software for the wiring closet on Cisco Catalyst 6500 Series
switches offering high-performance Layer 2 forwarding. It is optimized to deliver the high availability, enhanced
security,and integrated inline power support necessary for mission-critical wiring closet deployments. Cisco Catalyst
Operating System Software can also be extended to the distribution and core layers of the network when coupled
withCisco IOS Softwareonthe MSFC,providingrobust and advancedLayer 3 andLayer 4 functions.Thisoperating
mode is often referred to as “hybrid mode.” See Table 3 for software and hardware deployment options.
Cisco IOS Software and Cisco Catalyst Operating System Software Shared Features
All Cisco Catalyst 6500 Series supervisor engines, including the new Supervisor Engine 720, take advantage of
the industry-leading software and management capabilities of the Cisco Catalyst 6500 Series. Customers can apply
theirknowledge of Cisco Catalyst Operating System Software,Cisco IOSSoftware, CiscoWorks,and other graphical
and Web-based network management tools without the need to learn a new command-line interface (CLI)
or management system.
