Cisco Catalyst 6000/6500, Aim at Enterprise Network & Service Provider Networks

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) February 3, 2012 -- The Cisco Catalyst 6000/6500 family represents the flagship of the Cisco Catalyst switching product range. The switch is aimed at the enterprise network and also at service provider networks. The Catalyst 6000/6500 is chassis-based, which means that it consists of the same fundamental components as a Catalyst 4000/4500 switch (i.e., chassis, supervisor engine, and switching modules), which are now discussed in more detail.

Catalyst 6000/6500 Chassis

The chassis provided by the Catalyst 6000/6500 series switches vary across the Catalyst 6000 and Catalyst 6500 family. The differences between the Catalyst 6000 series chassis and Catalyst 6500 series are listed below:

Backplane— Both the Catalyst 6000 and Catalyst 6500 contain a shared 32-Gbps backplane; however, the Catalyst 6500 also supports an upgrade to a 256-Gbps crossbar switching matrix by adding an optional switch fabric module.
Scalability— The Catalyst 6000 is provided only in a 6-slot chassis (6006) and 9-slot (6009) chassis, while the 6500 provides 3-slot (6503), 6-slot (6506), 9-slot (6509), and 13-slot (6513) chassis options.

Supervisor Engines

The Cisco Catalyst 6000/6500 switch family consists of three Supervisor engines, which each vary in terms of functionality and performance:

Supervisor 1A— Provides support for advanced security and QoS features, as well as MLS-based (Multilayer switching) Layer 3 switching. The Supervisor 1A supports a backplane capacity of 32 Gbps and a Layer 2/Layer 3 forwarding rate of up to 15 Mpps.
Supervisor 2— Provides support for advanced security and QoS features, as well as CEF-based (Cisco Express Forwarding) Layer 3 switching. The Supervisor 2 also supports the switch fabric module (SFM), which increases backplane capacity from 32 Gbps to 256 Gbps and supports a Layer 2/Layer 3 forwarding rate of up to 210 Mpps.

Supervisor 720— Provides support for advanced security and QoS features, as well as advanced CEF-based Layer 3 switching. The Layer 3 switching engine supports IPv6 routing, network address translation, GRE tunneling, and MPLS all in hardware. The Supervisor 720 includes a crossbar switching matrix (formerly provided via the separate SFM in conjunction with the Supervisor 2), which provides a backplane capacity of 720 Gbps and a Layer 2/Layer 3 forwarding rate of up to 200 Mpps (IPv6) and 400 Mpps (IPv4). The Supervisor 720 also includes PFC3 and MSFC3 daughter cards (discussed later), which provide the Layer 3 switching capabilities of the Supervisor.

All supervisors can be installed in redundant pairs, ensuring maximum availability in the event of an active supervisor failure. Any additional add-on modules that extend system performance or functionality (e.g., SFM, PFC daughter card, and MSFC daughter card) can also be installed in a redundant configuration, ensuring the highest levels of availability

You have learned that the Supervisor 2 engine supports the SFM; each Supervisor also supports two types of add-on modules onboard the Supervisor itself (i.e., daughter cards), which extend the functionality and performance of the supervisor engine to provide the features and performance described above. These daughter cards are described as follows:

Policy feature card (PFC)— The PFC provides Layer 3/4 intelligence, allowing for advanced security and QoS features to be applied based upon the Layer 3 and Layer 4 parameters of traffic. The PFC also provides the hardware forwarding engine when Layer 3 switching is enabled with the addition of an MSFC. The PFC can be installed just by itself, without the MSFC (discussed next).

Multilayer switching feature card (MSFC)— The MSFC is essentially a router on a daughter card, providing full Layer 3 routing functionality and enabling the Catalyst 6000/6500 to perform Layer 3 switching. In a Layer 3 switching configuration, the MSFC provides the control plane component of L3 switching (i.e., populating and maintaining the routing table), while the PFC provides the data plane component of L3 switching (i.e., rewriting frame and packet headers and switching routed packets to the appropriate egress port), which means you must have a PFC installed before installing an MSFC. The MSFC also allows the switch to operate in native IOS, where the Supervisor and MSFC are managed via a single Cisco IOS-based management interface, integrating Layer 2 and Layer 3 switching management (similar to the Catalyst 3550 EMI and Catalyst 4000/4500 Supervisor 3/4).


NOTE
Without a MSFC, the Catalyst 6000/6500 Supervisor engines operate the CatOS operating system. When you add a MSFC, by default, the Supervisor still runs CatOS and the MSFC runs Cisco IOS (this configuration is known as referred to as hybrid IOS). You can then configure the switch to operate in native IOS mode, where the Supervisor and MSFC are managed by the same Cisco IOS management interface, as long as the switch has an MSFC installed.

There are three generations of PFC and MSFC modules, with various combinations of Supervisor engines and different versions of PFC and MSFC modules making it a reasonably complex task to understand which features are supported in each configuration. Chapter 6, “Layer 3 Switching,” discusses the features of the various Supervisor, PFC, and MSFC configurations in more detail.


Switching Modules
On the Catalyst 6500/6000, you can purchase three types of line cards:

Classic— A classic module connects to the 32-Gbps shared backplane only.
Fabric-enabled— A fabric-enabled module connects to both the 32-Gbps backplane and also has an 8-Gbps full-duplex connection to the 256-Gbps crossbar switch matrix (requires Supervisor 720 or switch fabric module installed).

Fabric-only— Connects only to the 256-Gbps crossbar switch matrix via dual 8-Gbps full-duplex connections (requires Supervisor 720 or switch fabric module installed).

Even though there are three types of modules, all modules can communicate with each other, even if they are attached to different switching backplanes (e.g., classic and fabric-only cards are not connected to the same bus). In this situation, an interconnection between the crossbar switching matrix is interconnected with the shared bus backplane allows classic cards and fabric-only cards to communicate. Table 1-8 lists some of the LAN switching modules available for the Catalyst 6000/6500.

Perhaps one of the best features of the Catalyst 6000/6500 switch is the capability to extend switch functionality well outside the bounds of pure LAN switching and Layer 3 switching. The Catalyst 6000/6500 not only provides LAN switching modules, which allow for high-density 10/100BASE-T, 10/100/1000BASE-T, and 1000BASE-X deployments, but also provides a wide range of other modules called services modules that extend and enhance the functionality of the Catalyst 6000/6500. The following lists some examples of the services modules available for the Catalyst 6000/6500 switch:

Firewall services module (WS-SVC-FWM-1-K9)— Essentially a PIX firewall on steroids, this module provides up to 5 Gbps firewall throughput, ensuring advanced security features can be implemented in the network without compromising performance.

IPSec virtual private network (VPN) services module (WS-SVC-IPSEC-1)— Provides up to 1.9 Gbps of triple DES VPN performance, ensuring private data can be protected without comprising performance.

Intrusion detection system module (WS-SVC-IDS2BUNK9), also known as IDSM)— Analyzes traffic from multiple VLANs for intrusive activity that might indicate an attack against the network, generating alarms and configuring security devices to block attacks. The latest IDSM can analyze up to 600 Mbps of traffic.

Content switching module (WS-SVC-CSG-1)— Provides intelligent application-layer load balancing for web server farms and other application server farms, providing enhanced performance, availability, and scalability.

Network analysis module (WS-SVC-NAM-x)— Provides intelligent network monitoring using Remote Monitoring (RMON) and network statistics using NetFlow capture.

As you can see from the preceding, the Catalyst 6000/6500 is not just a LAN switch; it is a platform that can integrate LAN switching features with advanced security, application, and network management features.

Catalyst Operating Systems
Today there are two main operating systems that are used on Cisco Catalyst switches:

Catalyst Operating System (CatOS)
Cisco Internetwork Operating System (Cisco IOS)

You are most likely familiar with Cisco IOS; Cisco IOS is the popular operating system installed on nearly all Cisco routers and is a very mature, feature-rich, and extensible operating system that offers Cisco customers significant value-add and return on investment. Historically, Cisco acquired a few major switch vendors in the early- to mid-1990s, which resulted in the introduction of what is now known as CatOS. CatOS is used to operate the following platforms:
