The inside of a Cisco 1900-series switch
Catalyst is the brand for a variety of network switches, wireless controllers and wireless access points sold by Cisco Systems. While commonly associated with Ethernet switches, a number of different network interfaces have been available throughout the history of the brand. Cisco acquired several different companies and rebranded their products as different versions of the Catalyst product line. The original Catalyst 5000 and 6000 series were based on technology acquired from Crescendo Communications. The 1700, 1900, and 2800 series Catalysts came from Grand Junction Networks, and the Catalyst 3000 series came from Kalpana in 1994.[1]
The newest version of the Catalyst is the Catalyst 9000 family. The Catalyst 9000 family includes switches, wireless access points, and wireless controllers [2]

Operating systems[edit]
In most cases, the technology for the Catalyst Switch was developed separately from Cisco's router technology. The Catalyst switches originally ran software called CatOS rather than the more widely known Cisco IOS software used by routers. However, this has changed as the product lines have merged closer together. In some cases, particularly in the modular chassis switches, a configuration called 'Hybrid' has emerged - this is where the layer 2 functions are configured using CatOS, and the layer 3 elements are configured using IOS. Native IOS can also be found with newer software versions that have eliminated CatOS entirely in favor of IOS, even on hardware that originally required CatOS.[3]
Some newer Catalyst switch models (with recent versions of the Cisco IOS) also allow web-based management using a graphical interface (GUI) module which is hosted on a HTTP server located on the switch. The Catalyst 2960-L SM Series of switches is an example of a Cisco Catalyst switch that allows this style of GUI via HTTP.
Cisco IOS[edit]
Cisco IOS, formally the Cisco Internetwork Operating System, is a family of network operating systems used on many Cisco Systems network switches, routers, wireless controllers and wireless access points. Earlier, Cisco switches ran CatOS. Cisco IOS is a package of routing, switching, internetworking and telecommunications functions integrated into a multitasking operating system. Although the IOS code base includes a cooperative multitasking kernel, most IOS features have been ported to other kernels such as QNX and Linux for use in Cisco products.Cisco Catalyst products run IOS or a Linux-derived version called Cisco IOS XE. It was originally called XDI[4] by the switching company Crescendo Communications, Inc. Cisco renamed it to CatOS when they acquired Crescendo and later still to Cisco IOS as the operating system was extended to other Cisco products. The newer Catalyst 9000 family uses the Cisco IOS XE operating system.[5]
Interfaces[edit]
As Catalyst devices are primarily Ethernet switches, all modern Catalyst models have Ethernet interfaces ranging from 10 Mbit/s to 100 Gbit/s depending on the model. Other models can support T1, E1, and ISDNPRI interfaces to provide connections to the PSTN.[citation needed] Legacy models supported a variety of interfaces, such as token ring, FDDI, Asynchronous Transfer Mode and 100BaseVG, but are no longer sold by Cisco Systems.
The front of a Catalyst 3750G switch, with 48 interfaces for Ethernet over twisted pair and four interfaces for small form-factor pluggable transceivers.
All models have basic layer 2 functions and are capable of switching Ethernet frames between ports. Commonly found additional features are VLANs, trunking and QoS. The switches, whether IOS or IOS XE, are fully manageable.
Many Catalyst switches that run IOS or IOS XE are also capable of functioning as a router, making them layer 3 devices; when coupled with TCP and UDP filtering, these switches are capable of layer 2-4 operation. Depending on the exact software image, a Catalyst switch that runs IOS or IOS XE may be able to tackle large-scale enterprise routing tasks, using router technologies like OSPF or BGP.
Modular chassis-based Catalyst switching models, like the Catalyst 9400 and 9600 Series, have the concept of field-replaceable supervisor, line cards, power supplies and fans. Mirroring most Cisco router designs, these work by separating the line cards, chassis, and supervisor engine. The chassis provides power and a high-speed backplane, the line cards provide interfaces to the network, and the supervisor engine moves packets, participates in routing protocols, etc. This gives several advantages:
- If a failure occurs, only the failed component needs to be replaced (typically a power supply, fan, line card or supervisor). This means faster turnaround than replacing an entire switch.
- A redundant component may be installed to rapidly recover from component failures.
- A supervisor engine may be upgraded after purchase, increasing performance and adding features without losing any investment in the rest of the switch.
Management[edit]
Catalyst switches offer advanced customization and manageability. The switches can be configured using a serial console, telnet or Secure Shell. Simple Network Management Protocol (SNMP) allows monitoring of many states, and measurement of traffic flows. Many devices can also run an HTTP server.
Configuration of the switch is done in plain text and is thus easy to audit. No special tools are required to generate a useful configuration. For sites with more than a few devices, it is useful to set up a Trivial File Transfer Protocol (TFTP) server for storing the configuration files and any IOS images for updating. Complex configurations are best created using a text editor (using a site standard template), putting the file on the TFTP server and copying it to the Cisco device. However, it can be noted that a TFTP server can present its own security problems.
Stackwise and Stackwise Virtual[edit]
Cisco StackWise and Stackwise Virtual are technologies offered by Cisco Systems that allows some models of Catalyst switches to operate as though they were one switch. One switch from the stack will act as the master switch. The master switch will maintain the stack and allow you to configure and monitor the whole stack as though one via a single console. This allows for more efficient management and typically provides more bandwidth between individual switches than other uplink technology.
If one switch fails, the remaining switches will continue to operate by bypassing it. If the master switch fails, another switch in the stack will automatically take over as master. This feature means greater redundancy, as one switch's failure will not bring about a failure of the entire stack.
As each switch contains the entire configuration for the stack, one of the benefits of this technology is the ability to replace a faulty switch (any—including master) with a new switch. The stack will configure the new switch on-the-fly to accommodate minimal downtime and reduce maintenance effort and errors.
Stackwise physically connects the switch stack using special stack interconnect cables, typically up to eight switches per stack. StackWise Virtual allows the virtual clustering of two chassis together into a single, logical entity without physical interconnect cables.
Master selection[edit]
The master switch of a stack is determined in the following order:[6]
- User specified priority in the switch configuration
- The switch with the most advanced IOS feature set enabled
- Programmed switch – A configured switch will preside over a switch running factory defaults
- Uptime – The switch that has been running the longest
- MAC address – The switch with the lowest MAC address
Models[edit]
There are two general types of Catalyst switches: fixed configuration models that are usually one or two rack units in size, with 12 to 80 ports; and modular switches in which virtually every component, from the CPU card to power supplies to switch cards, are individually installed in a chassis.
In general, switch model designations start with WS-C or C, followed by the model line (e.g. C9600). A letter at the end of this number signifies a special feature, followed by the number of ports (usually 24 or 48) and additional nomenclature indicating other features like UPOE (e.g. C9300-48U). Catalyst 9000 switches also include software subscription license indicators (e.g. C9200-48T-P, E for Essentials, A for Advantage and P for Premier)

Installation Procedures
A 2900 XL switch can be installed in a 19-inch or 24-inch standard rack, on a wall, or on a table or shelf. This section contains procedures for installing a switch in each of these locations.
Note The following illustrations show the Catalyst 2924 XL and 2924M XL switches as examples. Other switches in the series, including models two-rack-units high, can also be installed as shown here.
Before you begin the installation, decide how to mount the switch by reviewing the illustrations in this section. If you decide to mount the switch in a rack or on a wall, use the mounting brackets supplied with the switch.
Installing the Switch in a Rack
To install the switch in a 19-inch or 24-inch standard rack, follow the instructions described in these procedures:
•Removing screws from the switch
•Attaching the brackets to the switch
•Mounting the switch in a rack
•Attaching the optional cable guide
Removing Screws from the Switch
If you plan to install the switch in a rack, you must first remove screws in the switch chassis so that mounting brackets can be attached to the chassis. Figure 2-1 shows how to remove the chassis screws in a fixed-port and a modular port switch.
Figure 2-1 Removing Screws from the Switch
Attaching the Brackets to the Switch
The bracket orientation and screws that you use depend on whether you are attaching the brackets for a 19-inch or 24-inch rack. Use two of the supplied screws to attach each bracket, according to rack size:
•For a 19-inch rack, use the supplied Phillips flat-head screws to attach the long side of the bracket to the switch.
•For a 24-inch rack, use the supplied Phillips truss-head screws to attach the short side of the bracket to the switch.
Figure 2-2, , Figure 2-4, and , show how to attach a bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.
Figure 2-2 Attaching Brackets on Fixed-Port Switches (Front Panel Forward)
Figure 2-3
Attaching Brackets on Modular Switches (Front Panel Forward)
Figure 2-4 Attaching Brackets on Fixed-Port Switches (Rear Panel Forward)
Figure 2-5
Attaching Brackets on Modular Switches (Rear Panel Forward)
Mounting the Switch in a Rack
After the brackets are attached to the switch, use the four supplied Phillips machine screws to securely attach the brackets to the rack, as shown in Figure 2-6.
Figure 2-6 Mounting the Fixed-Port and Modular Switch in a Rack
After the switch is mounted in the rack, attach the power cord to the switch. If you are using the Cisco Redundant Power Supply (RPS), see the Cisco documentation that came with your RPS for installation instructions.
After the power is connected, the System LED is amber for 2 seconds, and then it flashes green while the switch completes a power-on self-test (POST), described in the 'POST Results' section.
Attaching the Optional Cable Guide
We recommend attaching the cable guides to prevent the cables from obscuring the front panel of the switch and the other devices installed in the rack. If the switch is in a 19-inch or 24-inch rack, you can attach the cable guide to the left or right bracket by using the supplied black screw, as shown in Figure 2-7. The cable guides for the modular switches require two screws.
Figure 2-7 Attaching the Cable Guide in a Fixed-Port and a Modular Switch
Installing the Switch on a Wall
To attach the switch to a wall, follow the procedures in this section:
•Attaching the brackets to the switch
•Attaching the switch to a wall
Attaching the Brackets to the Switch
The bracket orientation and the screws you use depend on whether you are attaching the brackets for parallel or vertical wall-mounting. Use two of the supplied screws to attach each bracket, according to the following guidelines:
•For parallel wall-mounting, use the supplied Phillips truss-head screws to attach the short side of the bracket to the switch.
•For vertical wall-mounting, use the supplied Phillips flat-head screws to attach the long side of the bracket to the switch.
Figure 2-8 and show how to attach the brackets to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.

Figure 2-9 Attaching Brackets for Parallel and Vertical Wall-Mounting for Modular Switches
Attaching the Switch to a Wall
For best support of the switch and cables, make sure the switch is attached securely to a wall stud or to a firmly attached plywood mounting backboard, as shown in Figure 2-10 and Figure 2-11.
Figure 2-10 Attaching the Fixed-Port Switch to a Wall
Figure 2-11 Attaching the Modular Switch to a Wall
After the switch is mounted on the wall, attach the power cord to the switch. If you are using the Cisco RPS, see the Cisco RPS documentation.
After the Cisco RPS is connected, the System LED is amber for 2 seconds, and then it flashes green while the switch completes a power-on self-test (POST), described in the 'POST Results' section.
Installing the Switch on a Table or Shelf
Follow these steps to install the switch on a table or shelf:
Step 1 Locate the adhesive strip with the rubber feet in the mounting-kit envelope. Attach the four rubber feet to the recessed areas on the bottom of the unit.
Step 2 Place the switch on the table or shelf near an AC power source.
Step 3 Connect the power cord to the switch rear panel and to the power outlet. If you are using the RPS, see the Cisco documentation that came with your RPS for installation instructions.
After the power is connected, the System LED is amber for 2 seconds, and then it flashes green while the switch completes a power-on self-test (POST), described in the 'POST Results' section.
POST Results
POST (a series of eight power-on self-tests) runs automatically to ensure that the switch functions properly. When the switch begins POST, the port status LEDs turn amber for 2 seconds, and then they turn green. As each test runs, the port LEDs turn off, starting with number 1X. The LEDs for ports 2X to 8X then go off in turn as the system completes a test.
When the POST completes successfully, all port status LEDs are off, indicating that the switch is operational. If a test fails, the port status LED associated with the test turns amber, and the system LED turns amber (see ',' for more information).
POST failures are almost always fatal. Call Cisco Systems immediately if your switch does not pass POST.
Connection Procedures
The procedures in this section explain how to connect devices to the 10/100 ports on the 2900 XL switch. For information on installing and connecting to modules in the expansion slots on the Catalyst 2924M XL and 2912MF XL switches, see the Catalyst 2900 Series XL Modules Installation Guide and the Catalyst 2900 Series XL ATM Modules Installation and Configuration Guide.
Connecting to the 10/100 Ports
The 10/100 ports configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters.
Connecting devices that do not autonegotiate or devices with manually set speed and duplex parameters can reduce performance or result in link failures between the devices. To maximize performance, choose one of these methods for configuring the 10/100 ports:
•Let the ports autonegotiate both speed and duplex.
•Set the port speed and the duplex parameters on both ends of the connection.
Follow these steps to connect to 10BaseT or 100BaseTX devices:
Step 1 When connecting to servers and workstations, insert a straight-through
Category 5 cable in a front panel RJ-45 connector, as shown in Figure 2-12.
Category 5 cable in a front panel RJ-45 connector, as shown in Figure 2-12.
Note When connecting to servers and workstations, be sure that the cable is a straight-through, twisted-pair cable. When connecting to switches or repeaters, use a crossover cable. Pinouts for the cables are described in the 'Straight-Through and Crossover Cable Pinouts' section.
Step 2 Insert the other end of the cable in an RJ-45 connector of the other device. The port status LED comes on when both the switch and the connected device are turned on.
The port status LED is amber while Spanning-Tree Protocol (STP) discovers the topology and searches for loops (this takes about 30 seconds). Then the port status LED turns green.
If the port status LED does not come on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device. See ',' for solutions to cabling problems.
Step 3 Reconfigure and reboot the connected device if necessary.
Step 4 Repeat steps 1 through 3 to connect additional devices.

Connecting to the 100BaseFX Ports
Follow these steps to connect to a fixed 100BaseFX ports:
Step 1 Remove the rubber plugs from the fiber-optic port and store them for future use.
Step 2 Insert the connector into the fiber-optic receptacle, as shown in Figure 2-13.
Do not remove the rubber plugs from the fiber-optic port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the fiber-optic port and cable from contamination and ambient light.

Connecting a Terminal or PC to the Console Port
Use the supplied rollover cable to connect a terminal or PC to the console port. The terminal or PC must support VT100 terminal emulation. The terminal-emulation software—frequently a PC application such as HyperTerminal or Procomm Plus—makes communication between the switch and your PC or terminal possible during the setup program.
Follow these steps to connect the terminal or PC to the switch:
Step 1 Be sure that your PC or terminal-emulation software is configured to communicate with the switch via hardware flow control.
Step 2 Configure the baud rate and character format of the terminal or PC to match these console port default characteristics:
•9600 baud
•Eight data bits
•One stop bit
•No parity
After you have gained access to the switch, you can change the baud rate of the port. See the Cisco IOS Desktop Switching Software Configuration Guide for instructions.
Step 3 Using the supplied rollover cable, insert the RJ-45 connector in the console port, as shown in . See the 'Console Port' section for a description of the pinout.
Step 4 Attach one of these supplied adapters to a PC or terminal:
•RJ-45-to-DB-9 female DTE adapter to connect to a PC
•RJ-45-to-DB-25 male adapter
Step 5 Insert the other end of the supplied rollover cable in the attached adapter.
Step 6 Boot the terminal-emulation program if you are using a PC or workstation.

IP Address Procedures
You can assign the switch an IP address by two methods:
•Using the setup program in the switch
•Using a BOOTP server
This section describes each method.
Note If you plan to configure this switch as a cluster member, you might not need to assign IP information. See the Cisco IOS Desktop Switching Software Configuration Guide for information on cluster management.
Using the Setup Program
The switch setup program assigns IP information and creates a default configuration that you can use to operate the switch. To run the setup program, access the switch from the terminal or PC that you connected to the console port. (The 'Connecting a Terminal or PC to the Console Port' section explains this procedure.) Later, you can customize the configuration by using Cisco Visual Switch Manager (CVSM) or the command-line interface (CLI).
The first time you access the switch, the setup program prompts you for an IP address, a subnet mask, and the IP address of the default gateway. Contact your system administrator for these numbers:
Switch IP address | ___________.___________.___________._________ |
Subnet mask (netmask) | ___________.___________.___________._________ |
Default gateway (router) | ___________.___________.___________._________ |
Follow these steps to assign the IP information to the switch:
Note Be sure the rollover cable is connecting a PC or terminal serial port to the console port. The data characteristics are 9600, 8, 1, no parity.
Step 1 Enter Y at the first prompt:
Continue with configuration dialog? [yes/no]: y
If this prompt does not appear, enter enable, and press Return. Enter setup, and press Return to start the setup program.
Step 2 Enter the switch IP address, and press Return:
Enter IP address: ip_address
Step 3 Enter the subnet mask (IP netmask) address, and press Return:
Enter IP netmask: ip_netmask
Step 4 Enter Y to enter a default gateway (router) address:
Would you like to enter a default gateway address? [yes]: y
Step 5 Enter the IP address of the default gateway (router), and press Return:
Enter router IP address: IP_address
Step 6 Enter a host name, and press Return:
Enter host name: host_name
Step 7 Enter a secret password (which ensures switch security), and press Return:
Enter enable secret password: <secret_password>
The initial configuration displays:
The following configuration command script was created:
interface VLAN1
ip address IP_address IP_netmask
ip default-gateway IP_address
enable secret 5 $1$jJql$VA6U.6uTjsa56Xx2yy/t30
snmp community private rw
snmp community public ro
!
end
!
Use this configuration? [yes/no]:
interface VLAN1
ip address IP_address IP_netmask
ip default-gateway IP_address
enable secret 5 $1$jJql$VA6U.6uTjsa56Xx2yy/t30
snmp community private rw
snmp community public ro
!
end
!
Use this configuration? [yes/no]:
Step 8 Verify that the addresses are correct.
Enter Y, and press Return if the displayed information is correct. If this information is not correct, enter N, press Return, and begin again at Step 2.
When you see the message 'Press RETURN to get started,' the setup program is complete. You can use your browser and CVSM (or the CLI) to continue the switch management session.
The Cisco IOS Desktop Switching Software Configuration Guide describes how to set a password to protect the switch against unauthorized Telnet access and how to access the switch if you forget the password.
Using a BOOTP Server
If a BOOTP server is accessible to the switch from any of its ports, you can use BOOTP to assign IP information to the switch. The BOOTP server must contain a list of physical MAC addresses and corresponding IP addresses. Other IP information that is part of the switch setup, such as the corresponding subnet mask and default gateway address, can also be stored on the server, but this information is optional.
When a switch starts and no IP address is assigned, it transmits a BOOTP broadcast requesting a mapping for its physical MAC address; this request is sent to all ports with a physical connection to the switch. A valid response must contain an IP address and can contain the subnet mask and default gateway address. If the switch receives a valid BOOTP response immediately, the remainder of the system protocol suite is activated.
A valid BOOTP response sets the IP information in the running configuration, but this information is not updated in the saved configuration in Flash memory. To update the IP information in the saved-configuration file, log in to the CLI, and enter the write memory command. This command records the IP information in the saved-configuration file, and no BOOTP request is required when the switch is reset.
