Cisco Catalyst 6500 Series Switches
The Cisco Catalyst 6500 Series Switches is one of the products and a modular chassis network that was developed by the Cisco Systems in the year of 1999. It is the Cisco Catalyst product that will offer you the speed that measures for up to 400 million packets every second.
The Cisco Catalyst 6500 Series Switches contain service modules, line cards, two or more supervisors, power supplies, and chassis. A single chassis can give you 13, 9, 6, 4, or 3 slots in every model of Cisco catalyst, including the Cisco Catalyst 6513, Cisco Catalyst 6509, Cisco Catalyst 6506, Cisco Catalyst 6504, and Cisco Catalyst 6503, correspondingly. You can choose from these Cisco Catalyst models with the options to have a single modular power supply or two. It also contains the supervisor engine that will offer you more centralized advancing processing and information that will give you the chance to install two of the different cards into the chassis and will provide you with the standby or active stateful failover. It also contains the various line cards that will offer you high-quality services and connectivity modules. It will also allow you to use these devices, including its firewalls, to be joined within its switches.
You can now get the security and resiliency that you will surely want with the use of this Cisco Catalyst 6500 Series Switches. This Cisco Catalyst platform has a broader range of pf deployed campus backbone switches. These switches are being enhanced for the Multi-gigabit Ethernet services that will help you to secure your investments of the network.
Operating Systems of Cisco Catalyst 6500 Series Switches
The Cisco Catalyst 6500 Series Switches presently supports by the three different operating systems. These operating systems are the Modular IOS, Native IOS, and the CatOS. Let us start discussing the Modular IOS operating system.
Modular IOS Operating System
The Modular IOS operating system is one of the versions of the Cisco IOS that usually works with the latest UNIX-based kernel that will help you to pass the different limits of the IOS. Furthermore, it can also perform the processes of patching without the help of rebooting the service and device upgrades.
Native IOS Operating System
The Cisco IOS can be used through RP and SP. In this situation, you, as the user, don’t have enough knowledge on where is the right place you will execute the command on its switches. Even if the two images of IOS are technically loaded, you can still use it. This is the operating system of the normal shipping mode that is meant for the different Cisco Nexus items. Through this, you can now enjoy the different line cards and beneficial features.
CatOS Operating System
The CatOS operating system is being supported by the switching layer or layer 2 operations. For you to perform the functions of routing by this CatOS operating system, you must switch its switch into the hybrid mode. In this situation, the CatOS operating system will work using the SP (Switch Processor) part of Supervisor. And its IOS will only work with the RP (Route Processor) which is also called as the MSFC. If you want to make some changes on its configurations, you should switch it manually in between of the two different environments. The CatOS operating system might have some missing functions and is considered as an “obsolete” when compared with the working switch of the Native Mode.
Different Methods of the Cisco Catalyst 6500 Series Switches Operations
The Cisco Catalyst 6500 Series Switches contains 5 basic operation modes. These are the dcef720, cef720, dcef256, cef256, and the Classic bus operation modes. Let us start first with the dcef720 operation mode.
Dcef720 Operation Mode
The Dcef720 is the operating system that works similarly with the dcef256 operation system. The only difference between the two operating systems is that the dcef720 operating system has the 20 x 2 GB connections that will switch the different fabric modules.
Cef720 Operation Mode
The Cef720 operation mode works similarly with the cef256 operation mode. The only difference between these two operating systems is that the cef720 operation mode has the 20 x 2 GB connections that will switch the fabric. You don’t also need to switch the fabric modules with this cef720 operation mode. It is because it already had the integrated supervisor feature. This is the first operation mode that was launched as the Supervisor Engine 720.
The number “720” in this Operation mode comes from the framework with the usage of the 20 x 2 GB ports on the 9 different slots by the 6509 frameworks. The reason behind this number is the computation of 9 x 40 is equal to 360 x 2 is equal to 720. The 720 number will be doubled when switched with the fabric, and it will become like the “full duplex.” The main reason why the 9 slots of frameworks are being used is that it has no chance to waste a single slot with the fabric module switches.
Dcef256 Operation Mode
The Dcef256 operation mode usually uses the forwarding distribution. This operation mode has 8 x 2 GB connections that will enable you to switch the fabric without using the classic bus connections. Only the module types that have the Distributed Forwarding Card (DCF) can only use this dcef256 operation mode.
Cef256 Operation Mode
The Cef256 is the operation mode that was first launched with the presence of the Supervisor 2 engine. When you use this operation mode in the mixture of the different switch fabric modules, every line card of this operation mode usually has the 8 gigabits per slot connection of the fabric switching. It also has a classic bus connection.
Classic Bus Operation Mode
The Cisco Catalyst 6500 classic architecture will offer you to the 32 Gigabit per slot that has the centralized forwarding performances. It has the design that looks like an incoming packet that is a line up first with a single line card and is placed with the dBus globally (data bus) and is started to be copied by the different line cards, such as the supervisor.
