• Upgradable - As newer modules come along, providing investment protection

Cisco Catalyst 6500 Series Hardware-Forwarding Architectures

Cisco Catalyst 6500 Series modules use one of three forwarding technologies, each having a different architecture with different characteristics and capabilities:

• Cisco Express Forwarding - Scaling to 30 mpps, this technology uses a central Cisco Express Forwarding engine located on the supervisor engine's policy feature card (PFC) daughter card and Cisco Express Forwarding tables located on the supervisor engine. The supervisor engine makes all forwarding decisions for all interface modules centrally.
• Distributed Cisco Express Forwarding - Suited for the most demanding environments, this technology uses the distributed Cisco Express Forwarding engine located on the interface module's distributed forwarding card (DFC) daughter card and the distributed Cisco Express Forwarding table, a local copy of the supervisor engine's central Cisco Express Forwarding table located on the interface module's DFC. The interface module makes all forwarding decisions locally, and provides maximum performance and scalability.

Cisco Catalyst 6500 Series Switching Architectures

Cisco developed the following switching architectures for Cisco Catalyst 6500 Series modules to allow platforms to scale in any deployment:

• 32-Gbps Bus - Allowing access to a central shared bus
• 256-Gbps Switch Fabric - Located on the switch fabric module (SFM)
• 720-Gbps Switch Fabric - Located on the Cisco Catalyst 6500 Series Supervisor Engine 720

Cisco Catalyst 6500 Series Modules

Cisco Catalyst 6500 Series interface modules support the following forwarding technology and switch-fabric combinations.

• Classic Interface Modules - Use the centralized Cisco Express Forwarding engine located on the supervisor engine's PFC, connect to the 32-Gbps switching bus only, and forward packets at up to 15 mpps
• CEF256 Interface Modules - Use the centralized Cisco Express Forwarding engine located on the supervisor engine's PFC, connect to both the 256-Gbps fabric located on the supervisor engine with a single 8-Gbps full-duplex fabric connection and the 32-Gbps switching bus, and forward packets at up to 30 mpps
• dCEF256 Interface Modules - Use the distributed Cisco Express Forwarding engine on the DFC (located on the interface module), connect to a 256-Gbps fabric located on the supervisor engine or a switch fabric module with 16-Gbps full-duplex fabric connections, and forward packets at up to 210 mpps
• dCEF720 Interface Modules - Use the distributed Cisco Express Forwarding engine on the DFC3 (located on the interface module), connect to the 720-Gbps fabric located on the supervisor engine with dual 20-Gbps full-duplex fabric connections, and forward packets at up to 400 mpps of sustained performance

Note: All performance numbers refer to IPv4 forwarding.

Cisco Catalyst 6500 Series Module Types

In the Cisco Catalyst 6500 Series architecture, special-purpose modules perform separate tasks-allowing the feature set to evolve quickly, and allowing customers to add features and enhance performance by adding new modules. The Cisco Catalyst 6500 Series features the following types of special-purpose modules:

• Supervisor Engines - Perform the control functions and make the forwarding decisions for packets routed to other networks
• Ethernet Interface Modules - Provide IEEE-standard receive and forwarding interfaces; forward packets within the defined network
• WAN Interface Modules - Provide the receive and forwarding interface at the WAN edge
• Services Modules - Support multigigabit security, application-aware Layer 4 through 7 content switching, wireless LAN services, network management, and voice gateway services to traditional phones, fax machines, PBXs, and the PSTN
• Switch Fabric Modules - Pass network traffic from the interface module to the supervisor engine or to another interface

Cisco Catalyst 6500 Series Supervisor Engines

The supervisor engines for the Cisco Catalyst 6500 Series support different forwarding technologies and achieve different forwarding rates, depending on the configuration of the supervisor engine and the capability of a particular interface module (Table 3).

Supervisor engines can be configured with optional factory-installed daughter cards-a PFC providing hardware-based Layer 2 forwarding, and a Multilayer Switch Feature Card (MSFC) providing Layer 3 capabilities.

A supervisor engine performs control operations centrally on processors that run either Cisco IOS Software or Cisco Catalyst Operating System Software while special-purpose, application-specific integrated circuits (ASICs) perform bridging and routing (based on Cisco Express Forwarding), QoS marking and policing, and access control. The same ASICs are used on the DFCs, daughter cards that can be installed on certain interface modules to distribute forwarding in a decentralized fashion to achieve system forwarding rates of up to 400 mpps.

Switch Fabric Modules

Designed to support distributed forwarding for interface modules with that capability, the Cisco Catalyst 6500 Series Switch Fabric Module (SFM or SFM2), in combination with the Cisco Catalyst 6000 Multilayer Switch Feature Card (MSFC2) and Cisco distributed forwarding cards (DFCs) on interface modules, increases available system bandwidth from 32 to 256 Gbps. The SFM or SFM2 supports the Cisco Catalyst 6500 CEF256 and dCEF256 interface modules.

Designed to support new interface modules with 720-Gbps forwarding capabilities, the switch fabric onboard the Cisco Catalyst 6500 Series Supervisor Engine 720 increases available bandwidth to 720 Gbps and provides packet-forwarding rates up to 400 mpps. By using automatic sensing and negotiation, the switch fabric is fully interoperable with the 8- and 16-Gbps switch-fabric interconnections used by the CEF256 and dCEF256 interface modules. When a CEF256 or dCEF256 interface module is detected, the switch fabric will automatically connect those modules by offering 8 to 16 Gbps of bandwidth to each module, as applicable.

How Cisco Express Forwarding Works

Cisco Express Forwarding is a Layer 3 technology that provides increased forwarding scalability and performance to manage the many short-duration traffic flows common in today's enterprise and service provider networks. To meet the needs of environments managing large amounts of short-flow, Web-based, or highly interactive types of traffic, Cisco Express Forwarding forwards all packets in hardware, and maintains its forwarding rate independent of the number of flows going though the switch.

On the Cisco Catalyst 6500 Series, the Cisco Express Forwarding Layer 3 forwarding engine is located centrally on the supervisor engine's policy feature card (PFC2 or PFC3)-the same device that performs hardware-based Layer 2 and Layer 3 forwarding, access control list (ACL) checking, QoS policing and marking, and NetFlow statistics gathering.

Using the routing table that Cisco IOS Software builds to define configured interfaces and routing protocols, the Cisco Express Forwarding architecture creates Cisco Express Forwarding tables and downloads them into the hardware forwarding engine before any user traffic is sent through the switch. The Cisco Express Forwarding architecture places only the routing prefixes in its Cisco Express Forwarding tables-the only information it requires to make the Layer 3 forwarding decisions-relying on the routing protocols to do route selection. By performing a simple Cisco Express Forwarding table lookup, the switch forwards packets at wire rate, independent of the number of flows transiting the switch.

Cisco Express Forwarding Requirements

A Cisco Catalyst 6500 Series Supervisor Engine 2 or Catalyst 6500 Series Supervisor Engine 720.

How Distributed Cisco Express Forwarding Works

With Distributed Cisco Express Forwarding, forwarding engines located on the interface modules make forwarding decisions locally and in parallel, allowing the Cisco Catalyst 6500 Series to achieve the highest forwarding rates in the industry. With Distributed Cisco Express Forwarding, forwarding occurs on the interface modules in parallel and system performance scales more than 400 mpps-the aggregate of all forwarding engines working together.

Using the same ASIC engine design as the central PFCx, distributed forwarding cards (DFCs) located on the interface modules forward packets between two ports, directly or across the switch fabric, without involving the supervisor engine. With the DFC, each interface module has a dedicated forwarding engine complete with the full forwarding tables. Distributed Cisco Express Forwarding (Figure 6) works like this:

• As in standard Cisco Express Forwarding, the central PFCx located on the supervisor engine and the DFC engines located on the interface modules are loaded with the same Cisco Express Forwarding information derived from the forwarding table before any user traffic arrives at the switch.
• As a packet arrives at an interface module, its DFC engine inspects the packet and uses the information in the Cisco Express Forwarding table (including Layer 2, Layer 3, ACLs, and QoS) to make a completely hardware-based forwarding decision for that packet.
• The Distributed Cisco Express Forwarding engine manages all hardware-based forwarding for traffic on that module, including Layer 2 and Layer 3 forwarding, ACLs, QoS policing and marking, and NetFlow.
• Because the DFCs make all the switching decisions locally, the central PFCx can dedicate more hardware-forwarding resources to any modules not equipped with a DFC.

Distributed Cisco Express Forwarding Requirements

Requires a Cisco Catalyst 6500 Series Supervisor Engine 720 for the dCEF720 interface module; requires either a Cisco Catalyst Supervisor Engine 720 or a Catalyst Supervisor Engine 2 multilayer switch feature card (MSFC) and a switch fabric module (SFM) for the dCEF256 interface module.

Cisco IOS Software and Cisco Catalyst Operating System Software

Cisco Catalyst 6500 Series switches offer two software operating modes-the Cisco Catalyst Operating System Software with optional Cisco IOS Software on the MSFC, and Cisco IOS Software for the supervisor engines. Each operating mode can be deployed at different hierarchies of the network, depending on the network's requirements. These software solutions for Cisco Catalyst 6500 Series switches provide full, high-performance Layer 2 through 4 switching and routing functions.

Today, either of these operating modes can be deployed in an entire network environment, or the operating modes can vary within an environment to meet different requirements. One operating mode is not a replacement for another, but is recommended for varying feature requirements.

Cisco IOS Software for the Cisco Catalyst 6500 Series

Cisco IOS Software for the Cisco Catalyst 6500 Series requires the MSFC on the supervisor engine. Cisco IOS Software provides integrated multilayer functions in a single image and is optimized for deployment in core and distribution networks, for Internet access, and in data centers. Combined with the performance of the Cisco Catalyst 6500 Series, Cisco IOS Software offers the necessary features for a high-performance, Layer 3-enabled deployment, including support for a distributed architecture with the capability 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 Cisco Catalyst 6500 Series switches.

The Cisco Catalyst 6500 Series with Cisco IOS Software Modularity boosts operational efficiency and minimizes downtime through evolutionary software infrastructure advancements. By enabling modular Cisco IOS subsystems to run in independent processes, this innovation:

• Minimizes unplanned downtime through self-healing processes
• Simplifies software changes through subsystem In-Service Software Upgrades (ISSU)
• Enables process-level, automated policy control by integrating Embedded Event Manager (EEM).

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 with Cisco IOS Software on the MSFC, providing robust, advanced Layer 3 and Layer 4 functions. This operating mode is often referred to as "hybrid mode." Table 4 lists 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 their knowledge of Cisco Catalyst Operating System Software, Cisco IOS Software, CiscoWorks, and other graphical and Web-based network management tools without the need to learn a new command-line interface (CLI) or management system.

Cisco Catalyst 6500 Series Chassis

Cisco Catalyst 6500 Series chassis can be deployed in the wiring closet, the distribution and core layers, the data center, and the WAN edge, providing the power and features required for end-to-end deployment for the enterprise campus, the ISP network, and metro and research computing networks.

Chassis Applications

The Cisco Catalyst 6500 Series provides 3-, 6-, 9-, and 13-slot chassis models with slots arranged horizontally, and a 9-slot model with slots arranged vertically, with front-to-back airflow. Typical applications for Cisco Catalyst 6500 Series chassis include:

• 3-Slot Chassis - Low-density, wiring-closet chassis sharing interface modules and supervisor engines with larger chassis for common sparing; low-density, high-performance specialized services module chassis for network security and management; and low-density, high-end chassis providing connectivity to the WAN edge
• 6- and 9-Slot Chassis - Traditional chassis for the wiring closet, distribution and core layers, data center, and WAN edge. The Cisco Catalyst 6506-E and Catalyst 6509-E support more than 4000 watts (W) power and higher per slot.
• 13-Slot Chassis - Highest-capacity chassis for Ethernet connectivity, with slots to spare for services modules, providing network security and management.

Chassis Configuration

All Cisco Catalyst 6500 Series chassis are NEBS Level-3 compliant and use common power supplies. The 6- and 9-slot chassis require a 1000W or 1300W power supply and the 13-slot chassis requires a 2500W or 4000W power supply. The 3-slot chassis requires a 950W power supply. When ordering a Cisco Catalyst 6500 Series switch, use the online Cisco Dynamic Configuration Tool to assist you in selecting the chassis, power supplies, power cables, and fan trays that will meet your requirements. The tool is available at https://tools.cisco.com/qtc/config/html/configureHomeGuest.html (Cisco.com login is required).

Power

All Cisco Catalyst 6500 chassis hold up to two load-sharing, fault-tolerant, hot-swappable AC or DC power supplies. Only one supply is required to operate a fully loaded chassis. If a second supply is installed, it operates in a load-sharing capacity. The power supplies are hot-swappable-a failed power supply can be removed without powering off the system.

Cisco Catalyst 6500 Series switch power supplies are available in the following power ratings (Table 5):

• 950W AC input (Cisco Catalyst 6503 and Catalyst 6503-E chassis)
• 1400W AC input (Cisco Catalyst 6503 and Catalyst 6503-E chassis)
