Catalyst 5000 Series Route Switch Feature Card Installation and Configuration Note 3
Functional Overview
Functional Overview
The RSFC is a router feature card for the Catalyst 5000 series Supervisor Engine II G and
Supervisor Engine III G modules. The RSFC runs Cisco IOS router software and directly interfaces
to the Catalyst switch backplane to provide interVLAN routing.
VLAN Interfaces
The RSFC contains no physical interfaces. InterVLAN routing is accomplished using virtual
interfaces that correspond one-to-one with the VLANs configured on the switch. For example, if you
configure VLAN 100 on the switch, you can configure an RSFC interface in that VLAN by creating
interface vlan100. All interface configuration on the RSFC is performed on these VLAN interfaces.
Note The RSFC supports interVLAN routing for up to 256 VLANs.
MAC Addresses
VLAN interfaces on the RSFC are assigned the base MAC address from a MAC address serial
EEPROM on the RSFC that contains 64 MAC addresses. All user-configurable routing interfaces
use the base MAC address by default. If desired, you can override the default MAC address
assignment for an interface. For more information, see the “Assigning a Nondefault MAC Address
to an Interface” section on page 22. Normally, there is no need to override the default MAC address.
System Memory Description
The RSFC system memory configuration is as follows:
•Boot ROM—The ROM monitor image is stored in an EPROM located on the RSFC.
•Flash memory—Flash memory allows you to store multiple Cisco IOS system software images
and configuration files on the RSFC. You can boot the RSFC from the images and configuration
files stored in Flash memory. The Flash memory on the RSFC consists of a single Flash device,
bootflash:, a Flash SIMM located on the feature card.
•NVRAM—The system configuration information and software configuration register settings
are stored in nonvolatile RAM (NVRAM).
•DRAM—DRAM stores routing tables, protocols, and network accounting applications. The
standard RSFC configuration is 64-MB DRAM, with support for up to 128-MB DRAM available
through SIMM upgrades.
System Software Description
The RSFC uses these system software images:
•ROM monitor—This software image runs from ROM at power up, in the event of a reload
request, or after a nonrecoverable event (such as a bus error). This image can access files on the
bootflash: device but does not have any network interface code.
•Boot helper image—This software image is a limited function system image that has network
interface code and end-host protocol code. This image is used as a backup in case a problem
occurs when the RSFC is programming Flash for the system image. This image is run from
RAM.

4Catalyst 5000 Series Route Switch Feature Card Installation and Configuration Note
Functional Description
•System image—This software image is the main Cisco IOS software image with full
multiprotocol routing support.
Note For information on how the RSFC uses these software images at startup, see the “RSFC Boot
Process” section on page 5.
Configuration Register Boot Field
The lowest four bits of the 16-bit configuration register (bits 3, 2, 1, and 0) form the boot field. The
value of the boot field determines if the RSFC loads a system image and where the RSFC searches
for the image:
•When the boot field is set to 0000 (0x0), the RSFC does not load a system image. Instead, the
RSFC enters the ROM monitor, where you can manually specify a system image to load.
•When the boot field is set to 0001 (0x1), the RSFC attempts to load the first system image found
on the bootflash: device.
•When the boot field is set to any value between 0010 (0x2) and 1111 (0xF) inclusive, the RSFC
attempts to load the first system image specified in the BOOT environment variable. (For more
information on the BOOT variable, see the “BOOT Environment Variable” section on page 4.)
For information on changing the configuration register boot field value, see the “Setting the
Configuration Register Boot Field” section on page 20. For more information on the RSFC boot
process, see the “RSFC Boot Process” section on page 5.
BOOTLDR Environment Variable
The BOOTLDR environment variable specifies one or more RSFC boot helper images. When the
BOOTLDR variable is defined, the RSFC boots the specified boot helper image, which in turn boots
a system image from Flash or over the network. If an entry in the BOOTLDR environment variable
list specifies an invalid device or file, the RSFC skips that entry.
For information on changing the BOOTLDR environment variable, see the “Setting the BOOTLDR
Variable” section on page 21. For more information on the RSFC boot process, see the “RSFC Boot
Process” section on page 5.
BOOT Environment Variable
The BOOT environment variable specifies one or more RSFC system images on various devices
(such as bootflash: and tftp:). If the configuration register boot field value is set to any value
between 0x2 and 0xF inclusive, the RSFC checks the contents of the BOOT variable at startup to
determine the location and filename of the image to boot.
If an entry in the BOOT environment variable list does not specify a device, the RSFC assumes the
device is tftp:. If an entry in the BOOT environment variable list specifies an invalid device, the
RSFC skips that entry.
For information on changing the BOOT environment variable, see the “Setting the BOOT Variable”
section on page 21. For more information on the RSFC boot process, see the “RSFC Boot Process”
section on page 5.

Catalyst 5000 Series Route Switch Feature Card Installation and Configuration Note 5
RSFC Boot Process
RSFC Boot Process
When you boot a Catalyst 5000 series switch with an RSFC installed, the following process occurs
on the RSFC:
1The ROM monitor image loads and checks the value of the configuration register boot field.
If the boot field equals 0x0, the boot process ends and the system remains in ROM monitor mode.
If the boot field equals 0x1, the ROM monitor proceeds to Step 2.
If the boot field equals any value between 0x2 and 0xF inclusive, the ROM monitor proceeds to
Step 3.
2The ROM monitor checks the contents of the BOOTLDR variable.
If one or more boot helper images are specified in the BOOTLDR variable, the ROM monitor
attempts to locate and load the images in the specified order. The ROM monitor loads into RAM
the first boot helper image that is successfully located and is a valid RSFC boot helper image file
and then proceeds to Step 4.
If the BOOTLDR variable is empty (no boot helper image is specified), if none of the specified
boot helper images can be located, or if none of the specified images are valid RSFC boot helper
images, the ROM monitor proceeds to Step 6.
3The ROM monitor checks the contents of the BOOT variable.
If one or more system images are specified in the BOOT variable, the system attempts to locate
and load the images in the specified order. The system boots the first image that is successfully
located and is a valid RSFC system image file, and the boot process ends.
If the BOOT variable is empty (no system image is specified), if none of the specified system
images can be located, or if none of the specified images are valid RSFC system images, the
system proceeds to Step 5.
4The boot helper image checks the contents of the BOOT variable.
If one or more system images are specified in the BOOT variable, the boot helper attempts to
locate and load the images in the specified order. The boot helper boots the first image that is
successfully located and is a valid RSFC system image file, and the boot process ends.
If the BOOT variable is empty (no system image is specified), if none of the specified system
images can be located, or if none of the specified images are valid RSFC system images, the
system proceeds to Step 6.
5The ROM monitor attempts to load the first image in bootflash:.
If there is a valid RSFC system image in bootflash:, the ROM monitor boots that system image
and the boot process ends.
If there is not a valid RSFC system image in bootflash:, the boot process ends and the system
remains in ROM monitor mode.
6The boot helper attempts to load the first image in bootflash:.
If there is a valid RSFC system image in bootflash:, the boot helper boots that system image and
the boot process ends.
If there is not a valid RSFC system image in bootflash:, the boot process ends and the system
remains in boot helper mode.

Hardware and Software Requirements
RSFC Redundancy
Up to two Catalyst 5000 series supervisor engines with RSFCs can be installed in the Catalyst 5505,
5509, and 5500 chassis. Redundant RSFCs do not exchange configuration or system image
information. Configuration changes on one RSFC do not affect the configuration of the second
RSFC. You must manually configure both RSFCs independently.
Both RSFCs in a redundant configuration are active (even though one of the supervisor engines is in
standby mode) and can perform routing functions. You can use the Hot Standby Router Protocol
(HSRP) on VLAN interfaces to provide router interface backup.
Intheevent that the activesupervisorenginefails, the system switches overtothestandbysupervisor
engine. In this case, the redundant RSFC takes over all routing functions of the first RSFC (provided
HSRP is configured properly on both RSFCs).
Note For information on configuring HSRP, see the “Configuring Redundancy Using HSRP”
section on page 17. For an example HSRP configuration, see the “Redundant RSFCs Using HSRP
Example” section on page 26.
Hardware and Software Requirements
The RSFC requires these software and hardware versions:
•Supervisor engine software release 5.1 or later on the Catalyst 5000 series Supervisor
Engine II G and Supervisor Engine III G modules
•Cisco IOS software release 12.0(3c)W5(8) or later on the RSFC
Safety Recommendations
Safety warnings appear throughout this note in procedures that, if performed incorrectly, may harm
you. A warning symbol precedes each warning statement.
Warning This warning symbol means danger. You are in a situation that could cause bodily injury.
Before you work on any equipment, be aware of the hazards involved with electrical circuitry and
be familiar with standard practices for preventing accidents. To see translations of the warnings that
appear in this publication, refer to the appendix “Translated Safety Warnings” in the Catalyst 5000
Series Supervisor Engine Installation Guide.
These sections describe how to ensure your safety when installing the RSFC:
•Ensuring Your Safety During Installation, page 6
•Basic Electrical Safety Guidelines, page 7
•Preventing ESD Damage, page 7
Ensuring Your Safety During Installation
Use the following guidelines to ensure your safety and protect the equipment. This list does not
include all potentially hazardous situations during installation, so be alert.
Warning Only trained and qualified personnel should install, replace, or service this equipment.

Catalyst 5000 Series Route Switch Feature Card Installation and Configuration Note 7
Basic Electrical Safety Guidelines
•Keep the chassis area clear and free of dust during and after installation.
•Keep tools and chassis components off the floor and away from foot traffic.
•Avoid wearing jewelry and securely fasten any loose clothing that could get caught in the chassis.
Warning Before working on equipment that is connectedtopowerlines,removejewelry(including
rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and
can cause serious burns or weld the metal object to the terminals.
Basic Electrical Safety Guidelines
When working with electrical equipment, exercise these basic safety guidelines:
•Never install equipment that appears to be damaged.
•Locate the emergency power-off switch for the room in which you are working before beginning
any procedures that require access to the chassis interior.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
•Examine your work area carefully for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Warning Do not work on the system or connect or disconnect cables during periods of
lightning activity.
Preventing ESD Damage
ESD damage occurs when electronic modules or components are improperly handled and can result
in complete or intermittent failures. To prevent ESD damage, follow these guidelines:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
•When handling modules or coming into contact with any internal components, always use a wrist
strap connected to one of the following:
—Captive installation screws on an installed module or power supply
—ESD wrist strap connector
—Any unpainted surface on the chassis
•Handle modules by the edges only.
•Avoid contact between the modules and clothing. The wrist strap protects only the module from
ESD voltages on the body; ESD voltages on clothing can still cause damage.
•After removing a supervisor engine, place it on an antistatic surface or in a static-shielding bag.
If you plan to return the module to the factory, immediately place it in a static-shielding bag.
Caution Periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohms (Mohms).

Required Tools and Equipment
These tools are required to install the RSFC:
•Phillips-head screwdriver
•Flat-head screwdriver
•ESD wrist or ankle strap
Removing and Replacing the Supervisor Engine
Note To support supervisor engine redundant operation, the supervisor engines must be either both
Supervisor Engine II Gs or both Supervisor Engine III Gs.
Note Catalyst 5505, Catalyst 5509, and Catalyst 5500 switches—When two supervisor engines
are installed, hot swapping allows you to remove and replace one of the supervisor engines without
turning off the system power.
These sections describe how to remove and replace the supervisor engine:
•Avoiding Problems When Inserting and Removing Modules, page 8
•Removing the Supervisor Engine, page 9
•Installing the Supervisor Engine, page 10
Avoiding Problems When Inserting and Removing Modules
The ejector levers on the supervisor engine align and seat the supervisor engine connectors in the
backplane. See Figure 1. If you fail to use the ejector levers to insert the supervisor engine, you can
disrupt the order in which the pins make contact with the backplane. When removing a supervisor
engine, use the ejector levers to ensure that the supervisor engine connector pins disconnect from the
backplane properly. Any supervisor engine that is only partially connected to the backplane can
disrupt the system.

Figure 1 Ejector Levers and Captive Installation Screws
Removing the Supervisor Engine
Beforeremoving thesupervisorengine module, back up the switch configurationfile as a precaution.
Use the write network command to back up your configuration to a Trivial File Transfer Protocol
(TFTP) server.
To remove the supervisor engine from the switch, follow these steps:
Caution To prevent ESD damage, handle switching modules by the carrier edges only.
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do
not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
Step 1 If you do not plan to immediately reinstall the supervisor engine you are removing,
disconnect any network interface cables attached to the uplink ports.
Step 2 Use a screwdriver to loosen the captive installation screws at the left and right sides of the
supervisor engine.
Step 3 Grasp the left and right ejector levers. Simultaneously pull the left lever to the left and the
right lever to the right to release the supervisor engine from the backplane connector.
Step 4 Grasp the supervisor engine with one hand and place your other hand under the carrier to
support and guide the supervisor engine out of the slot. Avoid touching any of the
components on the supervisor engine.
Step 5 Carefully pull the supervisor engine straight out of the slot, keeping your other hand
under the carrier to guide it. Keep the supervisor engine horizontal to the backplane.
Step 6 Place the removed supervisor engine on an antistatic mat or antistatic foam or bag.
Step 7 If the slot is to remain empty, install a module filler plate to keep dust out of the chassis
and to maintain proper airflow through the module compartment.

Removing and Replacing the Supervisor Engine
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure
to hazardous voltages and currents inside the chassis; they contain electromagnetic interference
(EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis.
Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Note When you remove and replace the supervisor engine, the system provides status messages on
theconsole screen. The messages areforinformation only. Entertheshow systemand showmodule
commands to view specific information. For additional information, refer to the Software
Configuration Guide and Command Reference publications for your switch.
Installing the Supervisor Engine
When installing the supervisor engine, note that it must go in a specific slot:
•Catalyst 5000—slot 1
•Catalyst 5505, 5509, and Catalyst 5500—slot 1 (if a second, redundant supervisor is installed, it
goes in slot 2)
•Catalyst 5002—slot 1
To install the supervisor engine, follow these steps:
Caution To prevent ESD damage, handle switching modules by the carrier edges only.
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do
not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
Step 1 Take the necessary precautions to prevent ESD damage, as described in the “Preventing
ESD Damage” section on page 7.
Step 2 To install the supervisor engine, hold the front panel with one hand, and place your other
hand under the carrier to support the supervisor engine. Do not touch the printed circuit
boards or connector pins.
Step 3 Align the edges of the supervisor engine carrier with the slot guides on the sides of the
switch chassis.
Step 4 Pivot the two module ejector levers out away from the faceplate. The ejector levers are
shown pivoted out in Figure 2.

Catalyst 5000 Series Route Switch Feature Card Installation and Configuration Note 11
Installing the RSFC
Figure 2 Module Ejector Lever Operation
Step 5 Keeping one hand under the carrier to guide the supervisor engine, carefully slide it into
the slot on the Catalyst 5000 series switch until the ejector levers click into place on the
chassis. Be sure to keep the module horizontal to the backplane and avoid touching any
of the components on the module.
Step 6 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers,
as shown in Figure 2, to fully seat the switching module in the backplane connector.
Caution Always use the ejector levers when installing or removing switching modules. A module
that is partially seated in the backplane will cause the system to halt and subsequently crash.
Step 7 Use a screwdriver to tighten the captive installation screws at the left and right sides of
the module.
Installing the RSFC
This section describes how to install the RSFC in your Supervisor Engine II G or III G.
Note To support redundant operation, both supervisor engines must be either Supervisor
Engine II Gs or Supervisor Engine III Gs.
Caution Use a wrist strap or other grounding device to prevent ESD damage. Refer to the
Catalyst 5000 Series Installation Guide for ESD details including the locations of the ESD
connectors on the Catalyst 5000 series switches.
To install the RSFC in the supervisor engine, follow this procedure:
Step 1 If not already removed, remove the supervisor engine from the Catalyst 5000 series
switch (see the “Removing and Replacing the Supervisor Engine” section on page 8 for
instructions).
Step 2 Place the supervisor engine on an antistatic mat or bag.
Step 3 Remove the RSFC from its antistatic bag and install it on the supervisor engine (see
Figure 3). Be careful when seating the RSFC connectors to the supervisor engine.

Catalyst 5000 Series Route Switch Feature Card Installation and Configuration Note 15
Configuring InterVLAN Routing on the RSFC
RSFC Configuration Guidelines
Configuring interVLAN routing on the RSFC consists of two main procedures:
1You must create and configure VLANs on the switch and assign VLAN membership to switch
ports. For more information, see the “Configuring VTP and VLANs on the Switch” section on
page 12.
2You must create and configure VLAN interfaces for interVLAN routing on the RSFC. You must
configure a VLAN interface for each VLAN for which you want to route traffic.
VLAN interfaces on the RSFC are virtual interfaces. However, you configure them in the same way
you configure a physical router interface.
Accessing the RSFC from the Switch
You can use the session mod_num command (where mod_num is the slot number associated with
the RSFC) to access the RSFC from the switch CLI, eliminating the need to connect a terminal
directly to the RSFC console port. To exit from the router CLI back to the switch CLI, enter exit at
the RSFC command prompt.
This example shows how to access the RSFC from the switch CLI, and how to exit the router CLI
and return to the switch CLI. In this example, because the RSFC is installed on the supervisor engine
in slot 1, the RSFC is assigned module number 15. An RSFC installed on the supervisor engine in
slot 2 is assigned module number 16.

Configuring IP InterVLAN Routing on the RSFC
To configure interVLAN routing for IP on the RSFC, perform this task:
Task Command
Step 1 (Optional) Enable IP routing on the router1.
1 This step is necessary if you have multiple routers in the network.
Router(config)#ip routing
Step 2 (Optional) Specify an IP routing protocol2.
2 This step is necessary if you enabled IP routing in Step 1. This step might include other commands, such as specifying the networks
to route for using the network router configuration command. Refer to the documentation for your router platform for detailed
information on configuring routing protocols.
Router(config)#router ip_routing_protocol
Step 3 Specify a VLAN interface on the RSFC. Router(config)#interface vlan-id
Step 4 Assign an IP address to the VLAN interface. Router(config-if)#ip address n.n.n.n mask
Step 5 Bring up the interface, if necessary. Router(config-if)#no shutdown
Step 6 Exit configuration mode. Router(config-if)#Ctrl-Z

Configuring Redundancy Using HSRP
This example shows how to enable AppleTalk routing on the RSFC, create a VLAN interface, and
assign the interface an AppleTalk cable-range and zone name:
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#appletalk routing
Router(config)#interface vlan100
Router(config-if)#appletalk cable-range 100-100
Router(config-if)#appletalk zone Engineering
Router(config-if)#no shutdown
Router(config-if)#^Z
Router#
Configuring Redundancy Using HSRP
You can configure one or more HSRP groups on RSFC VLAN interfaces to provide transparent
routing backup for the network. Each VLAN interface in an HSRP group shares a virtual IP address
and MAC address. You can configure end stations and other devices to use the HSRP address as the
default gateway so that the failure of one router interface does not interrupt service to those devices.
The interface with the highest HSRP priority is the active interface for that HSRP group.
To configure HSRP on an RSFC VLAN interface, perform this task in interface configuration mode:
Step 3 Assign a cable range to the VLAN interface. Router(config-if)#appletalk cable-range cable-range
Step 4 Assign a zone name to the VLAN interface. Router(config-if)#appletalk zone zone-name
Step 5 Bring up the interface, if necessary. Router(config-if)#no shutdown
Step 6 Exit configuration mode. Router(config-if)#Ctrl-Z
1 This step is necessary if you have multiple routers in the network.
Task Command
Step 1 Enable HSRP and specify the HSRP IP address.
If you do not specify a group-number, group 0 is
used.
standby [group-number]ip [ip-address]
Step 2 Specify the priority for the HSRP interface.
Increase the priority of at least one interface in
the HSRP group (the default is 100). The
interface with the highest priority becomes
active for that HSRP group.
standby [group-number]priority priority
Step 3 (Optional) Configure the interface to preempt
the current active HSRP interface and become
active if the interface priority is higher than the
priority of the current active interface.
standby [group-number]preempt [delay delay]
Step 4 (Optional) Set the HSRP Hello timer and
holdtime timer for the interface. The default
values are 3 (Hello) and 10 (holdtime). All
interfaces in the HSRP group should use the
same timer values.
standby [group-number]timers hellotime holdtime
Step 5 (Optional) Specify a clear-text HSRP
authentication string for the interface. All
interfaces in the HSRP group should use the
same authentication string.
standby [group-number]authentication string

To reset the RSFC from the switch CLI, perform this task in privileged mode:
Setting the Configuration Register Boot Field
The configuration register boot field determines whether or not the RSFC loads a system image, and
if so, where it should search for the system image. For more information on the function of the
configuration register boot field, see the “Configuration Register Boot Field” section on page 4.
To set the configuration register boot field value on the RSFC, perform this task in global
configuration mode:
This example shows how to change the configuration register boot field value to 0x2 (to cause the
RSFC to boot the system image specified by the BOOT variable), given the current configuration
register value of 0x101:
Router#show bootvar
BOOT variable =
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x101
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Task Command
Download a system image to the RSFC using TFTP from
the switch CLI. download host_ip_addr filename mod_num
Task Command
Reset the RSFC. reset mod_num
Task Command
Step 1 Obtain the current configuration register setting. show bootvar
Step 2 Enter configuration mode. configure terminal
Step 3 Modify the existing configuration register value.
Change the least significant hexadecimal digit to
a value between 0x0 and 0xF to reflect how you
want the RSFC to load a system image.
config-register value
Step 4 Exit configuration mode. Ctrl-Z
Step 5 Save the running configuration to NVRAM. copy running-config startup-config
Step 6 Reboot the RSFC to make your changes take
effect. reload
