Product Number: WS-X5009
This document contains instructions for installing and configuring the Catalyst 5000 series supervisor engine. Configuration examples are also provided. For a complete description of commands used to configure and maintain the Catalyst 5000 series switch, refer to the Catalyst 5000 Series Configuration Guide and Command Reference. For complete hardware configuration and maintenance procedures, refer to the Catalyst 5000 Series Installation Guide. These documents are available on the Cisco Connection Documentation, Enterprise Series CD-ROM, or in print.
Sections in this document include the following:
What is the Catalyst 5000 Series Switch?
The Catalyst 5000 series switch provides high-density switched Ethernet and Fast Ethernet for both wiring closet and data center applications. The switch includes a single, integrated 1.2-Gbps switching backplane that supports switched Ethernet with repeater connections, and Fast Ethernet with backbone connections, Fiber Distributed Data Interface (FDDI), Copper Distributed Data Interface (CDDI), and Asynchronous Transfer Mode (ATM). The Catalyst 5000 provides switched connections to individual workstations, servers, LAN segments, backbones, or other Catalyst 5000 switches using shielded twisted-pair (STP), unshielded twisted-pair (UTP), and fiber-optic cable. Figure 1 is an example of a configuration using the Catalyst 5000 series switch.
Figure 1 : Cascaded Switches Using Fast Ethernet Interfaces
The Catalyst 5000 series switch chassis has five slots. Slot 1 is reserved for the supervisor engine, which provides Layer 2 switching, local and remote management, and dual Fast Ethernet interfaces. The remaining four slots are used for any combination of modules for additional Ethernet, Fast Ethernet, CDDI/FDDI, and ATM connections. Figure 2 shows the rear view of the Catalyst 5000 series switch, which provides access to the supervisor engine, all switching modules, power supplies, and fan assembly.
Figure 2 : Catalyst 5000 Series Switch Chassis Rear View
The supervisor engine (see Figure 3) is the main system processor in the switch. It contains the
Layer 2 switching engine and network management processor for the system software, and also contains most of the system memory components. It maintains and executes the management functions that control the system.
The supervisor engine has the following features:
In addition to these features, the supervisor engine performs the following management functions:
The embedded Flash memory allows you to remotely load and store the system software image. You can download a new software image over the network or from a local server, and add the new image to Flash memory or replace an existing file.
An electrically erasable programmable read-only memory (EEPROM) component on the supervisor engine stores board-specific information such as the serial number, part number, controller type, hardware revision, configuration information, and other details unique to each board. In addition to this standard information, the supervisor engine EEPROM also contains an address allocator---a bank of 1024 hardware or MAC addresses---one for each possible VLAN in the system. For an explanation of the hardware addressing function, refer to "MAC Address Allocation" later in this configuration note.
LEDs on the supervisor engine (shown in Figure 4) indicate the status of the system; they are described in the section "Supervisor Engine LEDs."
Figure 4 : Supervisor Engine LEDs
Access to the reset switch, located behind the faceplate of the supervisor engine, is through a small hole approximately 1 1/2 inches to the right of the supervisor engine status LED. (See Figure 4.)
The switch load meter LEDs provide, as an approximate percentage, a visual indication of the current traffic load over the 1.2-Gbps switching backplane. (See Figure 5.)
The console port is the local, out-of-band, console terminal connection to the switch---a DB-25 female connector. To use the console port, connect an EIA/TIA-232 terminal (configured for 9600 baud, no parity, eight data bits, and one stop bit), modem or network management workstation. The console port lets you perform the following functions:
The supervisor engine provides two Fast Ethernet fiber-optic ports, operating in full- or half duplex mode. These ports use either multimode or single-mode fiber-optic cable between each port and your Fast Ethernet network.
Each Fast Ethernet port has two status LEDs---the 100-Mbps and Link LEDs---described in the section "Supervisor Engine LEDs."

When preparing your site for network connections to the switch, you need to consider a few factors related to each type of interface:
Before installing the switch, have all additional external equipment and cables on hand. If you intend to build your own cables, refer to the cable pinouts in the "Cabling Specifications" appendix in the Catalyst 5000 Series Installation Guide. For ordering information, contact a customer service representative.
Distance and rate limitations discussed in this section are IEEE recommended maximum speeds and distances for signaling. If you understand the electrical problems that may arise and can compensate for them, you may get good results with rates and distances greater than those described here, but you do so at your own risk.
The maximum distances for Fast Ethernet network segments and connections depend on the type of transmission cable used, for example, unshielded twisted-pair (100BaseTX).
The IEEE 100BaseTX standard recommends a maximum distance of 328 feet (100 meters) between station (connection) and switch for 100BaseTX connections using Category 5 UTP. For greater distances, use a fiber-optic transceiver attached to the MII connector.
Table 3 : Fast Ethernet Maximum Transmission Distances
| Transceiver Speed | Cable Type | Duplex Mode | Maximum Distance Between Stations |
|---|---|---|---|
| 100 Mbps | Category 5 UTP | Full & half | 328 feet (100 meters) |
| 100 Mbp | Multimode fiber | Full | 1.2 miles (2 km) |
| 100 Mbp | Multimode fiber | Half | 1,312 feet (400 meters) |
As with all signaling systems, serial signals can travel a limited distance at any given baud rate; generally, the slower the baud rate, the greater the distance. Table 4 shows the standard relationship between baud rate and distance for EIA/TIA-232 signals.

Fast Ethernet Connection Equipment
You will need an Ethernet transceiver and transceiver cable between each Fast Ethernet port and the Ethernet network. You can use two different Fast Ethernet connectors:
Figure 7 : Fast Ethernet RJ-45 Interface Cable Connectors
Figure 8 : Fast-Ethernet 40-Pin MII Interface Cable Connectors
Ethernet transceivers are available from a variety of sources for unshielded twisted-pair cabling (100BaseTX). Figure 9 shows examples of transceivers and connection equipment. You can connect either Ethernet Version 1 or Version 2/IEEE 802.3 interfaces. The switch automatically supports both types.
Figure 9 : Ethernet Transceivers and Connection Equipment
When planning your connections, consider the types and locations of connectors on adjacent switching modules to avoid having the transceiver overlap and impair access to other connections.
EIA/TIA-232, the most common interface standard in the U.S., supports unbalanced circuits at signal speeds up to 64 kbps. The supervisor engine console connection is a standard 25-pin, D-shell connector (known as a DB-25) commonly used for EIA/TIA-232 connections. Figure 10 shows the connector at the local end of the adapter cable. The system console port on the supervisor engine EIA/TIA-232 connection ports support only asynchronous connections. For further information on the console port, refer to the section "Console Port Connection Equipment."
When connecting serial devices, consider the adapter cables as an extension of the switch for external connections. Therefore, use data terminal equipment (DTE) cables to connect the switch to remote data communication equipment (DCE) devices, such as modems or data service units (DSUs), and use DCE cables to connect the switch to remote DTE devices such as a host or PC.
Figure 10 : EIA/TIA-232 Adapter Cable Connectors, Network End
Console Port Connection Equipment
The supervisor engine contains an EIA/TIA-232 asynchronous console port (DB-25 receptacle). Synchronous transmission uses precise timing to synchronize transmissions between the transmitter and receiver, and maintains separate clock and data signals. Asynchronous transmission uses control bits instead of a precise clock signal to indicate the beginning and end of characters.
You will need a terminal to configure the interfaces and bring up the system. You will also need an EIA/TIA-232 DCE console cable to connect the terminal to the console port on the supervisor engine. After you establish normal operation, you can disconnect the terminal. Both ends of the console cable should be EIA/TIA-232 plugs to enable you to connect to the supervisor engine DCE console port DB-25 receptacle and to the DB-25 receptacles used on the DTE ports on most terminals.
Before you connect a terminal to the console port, configure the terminal to match the switch console port, as follows:
Supervisor Engine Connector Signals
Most Ethernet transceivers require a transceiver cable to connect an Ethernet transceiver to the supervisor engine and Ethernet switching module Ethernet ports. Some unshielded twisted-pair (10BaseT) transceivers are compact enough to connect directly to the Ethernet module ports without impeding other connections. For descriptions of Ethernet transceivers, connectors, and cables, refer to the section "Fast Ethernet Connection Equipment."

The following guidelines will help to ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations that you may be exposed to when installing the switch, so be alert.
The supervisor engine, switching modules, and redundant power supplies are designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system. Before removing a redundant power supply, ensure that the primary supply is powered on.
You must shut down the system before removing or replacing any of the replaceable components inside the front panel---for example, the backplane. Never install equipment that appears damaged.
Follow these basic guidelines when working with any electrical equipment:
In addition, use the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone wiring or other network cabling.
Preventing Electrostatic Discharge Damage
Electrostatic Discharge (ESD) damage occurs when electronic or components are improperly handled, resulting in complete or intermittent failures. The supervisor engine and switching modules each consist of a printed circuit board (PCB) fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the metal carrier helps to protect modules from ESD, use a preventive antistatic strap whenever you handle the supervisor engine or switching modules. Handle the carriers by the handles and the carrier edges only, never touch the modules or connector pins.
Following are guidelines for preventing ESD damage:
Figure 11 : Placement of ESD Wrist Strap
Installing and Configuring the Supervisor Engine
The supervisor engine supports hot swapping, letting you install, remove, and replace it without powering off the system power. You do not need to notify the software or shut down the system power. However, hot swapping the supervisor engine will halt the system.
After the supervisor engine is reinstalled, the system automatically configures all network interfaces with the configuration last stored in the supervisor engine's nonvolatile memory. If the supervisor engine is new, the system uses the factory default configuration
All Catalyst 5000 supervisor engines and switching modules support hot swapping. This section gives a brief overview of the switch's hot-swap feature.
The supervisor engine contains a bus-type connector that connects to the backplane. Each connector consists of a set of tiered pins in two lengths. The pins send specific signals to the system as they make contact with the backplane. The system assesses the signals it receives and the order in which it receives them to determine what event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting down removed ones.
For example, when inserting the supervisor engine, the longest pins make contact with the backplane first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them. The system expects to receive signals from individual pins in this logical sequence.
When you remove or insert the supervisor engine, the backplane pins send signals to notify the system, and performs as follows:
When you insert a new supervisor engine, the system runs a diagnostic test on all interfaces, and compares them to the existing configuration. If this initial diagnostic fails, the system remains off line for another 15 seconds while it performs a second set of diagnostic tests to determine whether or not the supervisor engine or a switching module is faulty and if normal system operation is possible.
If the second diagnostic test passes, indicating that the system is operating normally and a new switching module is faulty, the system resumes normal operation but leaves the new interfaces disabled.
If the second diagnostic test fails, the system crashes, which usually indicates that the new supervisor engine or a switching module created a problem in the bus and should be removed.
Avoiding Problems When Inserting and Removing the Supervisor Engine
The function of the ejector levers (see Figure 12) on the supervisor engine is to align and seat the board connectors in the backplane. Failure to use the ejector levers and insert the supervisor engine properly can disrupt the order in which the pins make contact with the backplane. Follow the installation and removal instructions carefully, and review the following examples of incorrect insertion practices and results:
It is also important, when removing the supervisor engine, to use the ejector levers to ensure that the connector pins disconnect from the backplane in the logical sequence expected by the system. Detailed procedures for hot-swapping the supervisor correctly engine are included in the sections that follow.
Figure 12 : Ejector Levers and Captive Installation Screws
You need a flat-blade screwdriver to remove the supervisor engine, and to tighten the captive installation screws that secure the engine in its slot. Whenever you handle the supervisor engine, use a wrist strap or other grounding device to prevent ESD damage. See the section "Preventing Electrostatic Discharge Damage."
Removing the Supervisor Engine
Perform the following steps to remove the supervisor engine from the switch chassis:
Installing the Supervisor Engine
Always install the supervisor engine in slot 1. You can install any switching module in any of the four switching module slots, numbered 2 through 5. (See Figure 13.) Switching module fillers---blank switching module carriers---are installed in slots without switching modules to maintain consistent airflow through the switching module compartment.
Figure 13 : Module Slot Numbers
Following is the procedure for installing the supervisor engine:
Figure 14 : Supervisor Engine Installation
Bringing the Supervisor Engine On Line
Once installed, you need to bring the supervisor engine on line to configure the system interfaces. There are three ways to do this:
Refer to the Catalyst 5000 Series Configuration Guide and Command Reference for more details about the switch's configuration commands.
After you install the supervisor engine, use the following information to configure the systems interfaces. The section "Port Addresses" contains an overview of the module and port numbering scheme used to configure the Catalyst 5000 series switching modules. The section "Configuring the Fast Ethernet Ports" describes how to configure the ports on the supervisor engine and switching modules. The section "Checking the Configuration" describes the procedures you should use to confirm that the module is configured correctly.
Each interface in the Catalyst 5000 series switch is designated by several different types of addresses. The physical interface address is the actual slot and port of the interface connector within the chassis. The system software uses the physical addresses to control activity within the switch and to display status information. These slot and port addresses are not used by other devices in the network. They are specific to the individual switch and its internal components and software.
A second type of address is the MAC or hardware address---a standard data link address required for every port or device connected to a network. Other devices in the network use these addresses to locate specific ports in the network, and to create and update routing tables and data structures. The Catalyst 5000 series switch uses a unique method to assign and control the MAC addresses of its interfaces.
The following sections describe how the Catalyst 5000 series switch assigns and controls t MAC addresses to slots and ports within the chassis.
In the Catalyst 5000 series switch, physical port addresses specify the actual physical location of each port on the rear of the switch. (See Figure 15.) The address is composed of a two-part number in the format slot number/port number. The first number identifies the slot in which the supervisor engine or switching module is installed. Module slots are numbered 1 to 5, from top to bottom. The second number identifies the physical port number on the switching module. The port numbers always begin at 1 and are numbered from the left port to right port when facing the rear of the switch. The number of additional ports (/1, /2, and so on) depends on the number of ports available on the module.
Interface ports maintain the same address regardless of whether other switching modules are installed or removed. However, when you move a switching module to a different slot, the first number in the address changes to reflect the new slot number. For example, on a 12-port 10/100BaseTX switching module in slot 2, the address of the left port is 2/1 and the address of the right port is 2/12. If you remove the 12-port 10/100Base TX switching module from slot 2 and install it in slot 4, the addresses of those same ports become 4/1 and 4/12.
Figure 15 : Interface Port Address Examples
The supervisor engine is always n/1 to n/2, because it supports two interfaces---ports 1 and 2. Switching modules are always n/1 to n/12 because each switching module supports at least twelve interfaces. (Switching modules with more than 12 interfaces are addressed n/1 through n/n.)
You can identify supervisor engine and switching module interfaces by physically checking the slot and port location on the back of the switch. You can also use software commands to display information about a specific interface, or all interfaces, in the switch. To display information about every interface, use the show port command without parameters. To display information about a specific interface, use the show port command with the interface type and port address in the format show port [mod_num/port_num]. If you abbreviate the command (sho po) and do not include parameters, the system interprets the command as show port and displays the status of all interfaces.
Following is an example of how the show port command without parameters displays status information (including the physical slot and port address) for each interface in the switch. In this example, most of the status information for each interface is omitted.
For complete descriptions of the commands used to configure and maintain the Catalyst 5000 series switch, refer to the Catalyst 5000 Series Configuration Guide and Command Reference.
All network interface connections require a unique MAC address. The switch uses a MAC address allocator, stored in the supervisor engine's nonvolatile memory which identifies all system interface addresses. Each switch interface, configured or not, is allocated a MAC address. For instance, interface 2/10 is allocated a MAC address as a Fast Ethernet connection configured in slot 2,
Configuring the Fast Ethernet Ports
Once the supervisor engine is installed, it will use the default configuration to configure the system's Fast Ethernet ports. This section describes how to use the privileged interface to configure the Fast Ethernet ports on the supervisor engine.
A description of the system's defaults is in the section "Default Configuration." Refer to the chapter "Configuring the Software" in the Catalyst 5000 Series Installation Guide for more information about customizing interface configurations.
To configure Fast Ethernet ports, complete the tasks in the following sections:
The supervisor engine provides the following default configuration. The default values can be changed to suit your network requirements.
Use the enable command to enable privileged mode. Privileged mode lets you invoke privileged commands that set the interface features, such as enabling an interface and showing the current configuration.
Example
The following example shows how to enter privileged mode:
Assign a name to each port. To set a port name, perform the following tasks in privileged mode:
Figure 16 : set port name Command Example
Figure 17 : Sample show port Command Display
Figure 18 : set port level Command Example
Set the transmission type to full- or half-duplex for the ports to be used. To set the transmission type, perform the following tasks in privileged mode:
Figure 19 : set port duplex Command Example
VLANs allow ports on the same or different switches to be grouped so that traffic is confined to members of that group only. This feature restricts unicast, broadcast, and multicast traffic (flooding) to ports included in the same VLAN.
The set vlan command groups ports. The default configuration for all switched Ethernet ports and Ethernet repeater ports in VLAN 1. You can enter groups of ports as individual entries, such as 2/1,3/3,3/4,3/5. You can also use a hyphenated format to indicate a range of ports, such as 2/1, 3/3-5.
To create a VLAN across a networking domain, perform the following steps in privileged mode:
Figure 20 : set vtp Command Example
Figure 21 : show vtp domain Command Example
Figure 22 : set vlan Command Example

To create a VLAN across a networking domain, perform the following steps in privileged mode:
Figure 25 : set vlan Command Example
Figure 26 : VLAN Configuration
Figure 27 : Sample show vlan Command Display
Use the set trunk command to configure trunks on ports, and to configure the mode for the trunk: on, off, desirable, or auto. To establish a trunk, the port on each Catalyst 5000 series switch must be configured as a trunk port. To establish trunks, perform the following steps in privileged mode:
Figure 28 : set trunk Command Example
Figure 29 : show trunk Command Display Sample
This section describes procedures to use to confirm that your supervisor engine is installed and configured correctly.
Use the ping command to send Internet Control Message Protocol (ICMP) echo request packets to another node on the network. Enter Ctrl-C to stop pinging.
Syntax Description
Following are sample results of the ping command:
Example
In the following example, a host with IP alias elvis is pinged a single time, then pinged once every second until you enter Ctrl C to stop pinging:
Use the show system command to display the power supply, fan, temperature alarm, system, and modem status; the number of days, hours, minutes, and seconds since the last system restart; the baud rate; the MAC address range; and the system name, location, and contact.

Define the VLAN, indicating the parameters described above: VLAN number, name, type, maximum transmission unit, SAID, state, ring number, bridge identification number, and number to indicate whether source routing should be set to transparent or bridging. A maximum of 250 VLANs can be active at any time. Figure 22 shows an example of the set vlan command. Figure 23 shows a diagram of the established VLANs, illustrating how VTP can traverse trunk connections using the ISL and 802.10 protocols and ATM LAN emulation (LANE). In Figure 23, Ethernet VLAN 1 is translated to FDDI VLAN 4 on the FDDI module, Ethernet VLAN 2 is translated to FDDI VLAN 5, and so on.
