Catalyst 6500 Series Switches are widely deployed campus backbone switches. They are optimized for Multigigabit Ethernet services to help you protect your network investment. 12.2(18)SXF 12.2(14)SX 12.2(33)SXH 15.0(1)SY WS-6506-E Specification Number of Slots 6 Supervisor Compatibility Cisco Catalyst 6500 Series Supervisor Engine 32.

Could someone clarify the following statement from Cisco 6500 Supervisory Engine 720 datasheet -Delivering upto 40Gbps per slot of switching capacity, 720 Gbps aggregate bandwidth. Like does this mean that a single slot from the 6500 chassis will switch 40Gbps of data. 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. Figure 1-9 and Figure 1-10 shows examples of the Catalyst 6000 and 6500 chassis (the Catalyst 6006 and 6509). The Catalyst 6509-E switch is an enhanced version of the Catalyst 6509 switch. The 9-slot horizontal chassis supports redundant power supplies, redundant supervisor engines, and slots for up to eight modules. It also supports a greater power capacity per slot than the Catalyst 6509 switch chassis.

“What differences btw catalyst 4500 and 6500 series? Our company is looking to get a new switch for or core/OC. The switch being replaced is an Enterasys matrix, I don’t know which model, but is very old, and all servers have been upgraded, we’re looking to get all of them on Gigabit Ethernet.”

“The network guy is looking to get a 4500, but I’m interested in get real view of both the 6500 and 4500, and how them compares to each other. I can see the 4500 are more compact, and both of them are current line switches. Interest points would be:
-how much time is left for each one before they become EoL
-what options can support one that the other can’t
-what is performance like on both of these beasts”

“Can anyone guide me on the difference b/w Cisco 6500 E & 4500 Switch (Hardware & software both)?”

The questions above were put forward by Cisco users. All right, what the main difference btw catalyst 6500 and Cisco 4500 Series. Besides reading specific datasheet of Cisco 6500 and catalyst 4500 switches from Cisco’s website, here we collected some experiences from Cisco 6500 and 4500 users, which may give you some hints and advices to select a right one for your company or enterprise.

Let’s have a look:

1. Review on Cisco catalyst 6500 & Cisco 4500 Series: Everything depends on how much load/throughput you’re pushing through the core now. The 4500 can act as a downsized core switch, and with SupV you can even get 10Gb links.

The 4500 replaced the 4000 model product line, expect it to be around for a while. The 6500 has been around for a while already, but it has been re-newed with new 6500-E chassis, and soon a 6500-NEB-E (vertical blade positioning, front-to-back cooling, more of a telco type chassis) will be released. The 6500 is the biggest switch Cisco makes now. Expect it to be around for a while as well.

The 6500 can support a lot more functions with special feature blades, like firewall, content load balancing, FlexWAN, etc. Both support PoE. The blades between 4500 and 6500 are NOT compatible or inter-changeable.

You should check out Cisco’s site for that, but 6500 is the core datacenter switch, whereas the 4500 is positioned for more wiring closet or server aggregation.

In real world, I use 4507Rs and 4510Rs as my wiring closet/server aggregation switches, as well as 3750Gs for server aggregation, and I use 6500s for core and distribution (I also recommend not looking at 6513, unless it’s 6513-E, which I don’t think is out yet). The environment is gig to the desktop (with PoE) and gig to the server (sometimes bonded 2gig to database servers).

In addition QoS support on the 6500 and 6500 line cards is far superior to the 4500. The newer blades on the 6500 are fabric-enabled, and have a 40-Gbit connection to the backplane, which connects the blade to a Supervisor module. Internally within those blades that have DFCs (Distributed Forwarding Card), the throughput on the card itself (say going from one port on the card to another) is 64-Gbit.

2. General overview on Cisco Catalyst 6500 Switches and 4500 Switches: Generally 4500’s are used in the Access Layer (TR) in lieu of a fixed switch. They can also be used in the Distribution Layer as well. Typically 6500’s are used in the Distribution and Core Layers, as they are a more robust layer 3 switch. Each slot on a 4500 is limited to only 6Gbps total.

The Cisco Catalyst 4500 Series includes four chassis options: Cisco Catalyst 4510R-E (10 slots), Cisco Catalyst 4507R-E (7 slots), Cisco Catalyst 4506-E (6 slots), and Cisco Catalyst 4503-E (3 slots). The Cisco Catalyst 6500 includes the 3 slot, 6 slot, 9 slot and 13 slot versions.

I believe the supervisor engine in the 6500 is also more powerful, and you have a wider range of card options for the 6500.

3. Cisco 6500 and 4500 Switches User’s Experience:“There are indeed many many differences. And many of the difference will come in the supervisors. I use both 6500 and 4500 switches. Both do layer 3, voice vlans, QOS. However, if you need functions such as nbar or netflow, the 6500 is the way to go. 4500’s either have limited or no support of these functions, because of their supervisors. A supe IV for a 4500 can support netflow if you buy the netflow daughter card. Same is true with a Supe V. A Supe V 10 Gig supports netflow without an extra purchase. The newer supe 6’s don’t support it at all.”

4. Cisco Upgraded Catalyst 4500 and 6500 Switches in 2007. The new improvements on Cisco 4500 and Catalyst 6500 Series are designed to better support peer-to-peer and real-time applications. They are the Cisco Catalyst 6500 Series Virtual Switching System 1440, which combines multiple Catalyst 6500 switches into one and scales system bandwidth capacity to 1.44 terabits per second; and the Cisco Catalyst 4500 E-Series with CenterFlex technology, which the company says it provides high network performance for rich applications.

The Cisco Catalyst 6500 Series Virtual Switching System 1440 is enabled by the Virtual Switching Supervisor Engine 720 with 10 Gigabit Ethernet, hardware module that can make two 6500 switches behave and appear to administrators as one.

The Cisco Catalyst 4500 E-Series with CenterFlex technology now delivers 320 gigabits per second and a fourfold increase in per-slot bandwidth using its unique centralized and flexible architecture. It provides 250 mpps (million packets per second) centralized performance and is based on Cisco’s new CenterFlex technology which resulted in the filing of 19 new technology patents enhancing security, quality of service (QoS) and performance, the company claims.
