Product Description
Product Description
This section contains a detailed description of the Token Ring interface processor (TRIP). The TRIP,
shown in Figure 1, provides twoor four Token Ring portsfor interconnection with IEEE 802.5 and
IBM Token Ring media. TheTRIPuses the IBM 16/4-Mbps chipset withanimbedded performance
enhanced interface driver and 16.7 MHzbit slice processor for highspeed processing. The speed on
each port is set independently with a software command for either 4 or 16 Mbps. The TRIP firmware
(microcode), which contains card-specific software instructions, resides in a ROM in socket U41.
You may need to replace this componentinthefuture to enable new features or enhancements (if so,
replacement instructions will be provided with the replacement component in an upgrade kit). The
TRIP and all other interface processors support online insertion and removal (OIR), which allows
you to remove and install a TRIP while the system is operating, without shutting down system
power.

prevent electrostatic damage (ESD), we recommend that you never remove or separate the printed
circuit board from the metal carrier.
Interface processor slotsare accessed fromthe rear ofthe chassis. TheTRIP can beinstalled in any
available interface processor slot. Each port on the TRIP requires a media access unit (MAU) to
connect the DE-9TRIP connectors to the external Token Ring networks.
The enabled LED light on the TRIP lights to indicate the following status of the TRIP:
• Enabled for operation
• Correctly connected to the backplane
• Receiving power
• Contains a valid microcode version
If any ofthese conditions isnot met, orif the initialization fails for otherreasons, the EnabledLED
does not light.
2 Token Ring Interface Processor (TRIP) Installation and Configuration
When a Token Ring interfaceis configured by using software commands, three LEDs for each port
indicate the following:
• 16 Mbps—Lights if the interface is operating at 16 Mbps.
• 4 Mbps—Lights if the interface is operating at 4 Mbps.
• In Ring—Whenlit,indicatesthattheinterfaceiscurrentlyactive and inserted intothering.When
not lit, the interface is not active and is not inserted into a ring.
Token Ring Connection Equipment
You will need an 802.5 MAU or a multistation accessunit(MSAU) to provide the interfacebetween
the TRIP Token Ring interfaces and the external ring, and a Token Ring lobe cable between each
TRIP port and theMAUor MSAU.Lobe cables connect each Token Ring station (TRIP port)to the
MAU or MSAU, and patch cables can connect adjacent MSAUs to form one large ring.
TRIP ports operate at either 4 or 16 Mbps. The default speed for all TRIP ports is 4 Mbps, which
you can change to 16 Mbps on anyport using the configuration command ring-speed n, where n is
the speed (4or 16) in Mbps. The speed ofeach Token Ring port must match thespeed of the ring to
which it is connected. Before you enable the Token Ring interfaces, ensure that each is set for the
correct speed, or it can bring down the ring.
Product Description
Caution Each TRIP port must be configured for the same ring speed as the ring to which it is
connected, either 4 or 16 Mbps.Iftheportissetforadifferentspeed,itwillcausetheringtobeacon,
which effectively brings the ring down and makes it inoperable.
Token Ring Cables and Connectors
The Token Ring ports on the TRIP are DB-9 (PC type) receptaclesthatrequireType1or Type 3 lobe
cables. Type 1 lobe cables use shielded twisted pair cable and terminate at the network end with a
large MAU plug. (See Figure 2.) Type 3 lobe cables use either shielded or unshielded twisted pair
(UTP) cable and terminate at the network end with an RJ-11 plug. (See Figure 2.) The TRIP end of
both cable types is a DB-9 plug.

Token Ring Physical Connections
The term Token Ring refers to both IBM’sTokenRingNetwork,whichIBMdeveloped in the 1970s,
and to IEEE 802.5 networks. The IEEE 802.5 specification was modeled after, and still closely
shadows, IBM’s network. The two types are compatible, although the specifications differ slightly.
Token Ring and IEEE 802.5 aretoken passing networks, whichmove a small frame,called a token,
around the network. Possession of the token grants the right to transmit; a station with information
to transmit must wait until it detects a free token passing by.
The IBM Token Ring specifies a star topology, with all end stations connected through a device
called a multistation access unit (MSAU). IEEE 802.5 does not specifyanytopology, although most
implementations are based on a star configuration with end stations attached to a device called a
media access unit (MAU). Also, IBM Token Ring specifies twisted-pair cabling, whereas IEEE
802.5 does not specify media type. Most Token Ring networks use shielded twisted-pair cabling;
however, some networks that operate at 4 Mbps use unshielded twisted-pair cable. Table 1 shows a
comparison of the two types.

All TRIP ports support both 4- and 16-Mbps operation and early token release. The default for all
ports is for 4 Mbps operation and early token release disabled. Both states are enabled with
configuration commands in the configuration mode. To enable 16 Mbps, specify the slot/port
address and use the configuration command ring-speed 16; to return to 4 Mbps operation, use the
command ring-speed 4. To enable and disable early token release,specify the slot/port addressand
use the configuration command [no] early token release. For complete descriptions and examples
of software commands, refer to the related software configuration documentation.

10 Token Ring Interface Processor (TRIP) Installation and Configuration
Installation Prerequisites
This section provides a list of parts and tools you will need to perform the installation, and safety
and ESD-prevention guidelines to help you to avoid injury and damage to the equipment. It also
provides a detailed description of the online insertion and removal (OIR) function to help you
perform online installation successfully and avoid error message and system restarts. If you are
installing a new TRIP, be sure to review the equipment descriptions and distance limitations in the
section “Distance Limitations for Token Ring Connections” on page 11 when preparing your site
and planning network connections.
Distance Limitations for Token Ring Connections
The maximum transmission distance is not defined for IEEE 802.5 (Token Ring) networks. Shielded
twisted-0pair cabling is most commonly used for rates of 4 and 16 Mbps. Twisted pair cabling is
more susceptible to interference than other types of cabling; therefore, the network length and
repeater spacing should be planned accordingly.
Ring Speed Considerations
Before you install the TRIP, determine the ring speed (4 or 16 Mbps) of each ring to be connected
to the server. There is no factory default for the interface speed; you must set the speed of each
interface (within the setup command facility or with the ring-speed command) before you bring the
interface up and insert it into the ring with the no shutdown command.
Installation Prerequisites
If an interface has an undefined or incorrect ring speed and is not shut down, the ring will beacon.
This effectively takes the ring down and makes it inoperable.
Safety
Following are safety guidelines that you should follow when working with any equipment that
connects to electrical power or telephone wiring.
Electrical Equipment Safety
Follow these basic guidelines when working with any electrical equipment:
• Before beginning any procedures requiring access to the chassis interior, locate the emergency
power off switch for the room in which you are working.
• Disconnect all power and external cables before moving a chassis.
• 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.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Token Ring Interface Processor (TRIP) Installation and Configuration 11
Installation Prerequisites
Telephone Wiring Safety
Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge (ESD) Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. The TRIP comprises a printed
circuit board that is 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 the board from ESD, use a preventive antistatic strap whenever handling the TRIP. Handle
the carriers by the handles and the carrier edges only; never touch the boards or connector pins.
Following are guidelines for preventing ESD damage:
• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
• Connect the equipment end of the strap to a captive installation screw on an installed power
supply.
• When installing a TRIP, use the ejector levers to properly seat the bus connectors in the
backplane, then tighten both captive installation screws. (See Figure 10.) These screws prevent
accidental removal,provide proper grounding for the system,and they help to ensure that the bus
connectors are seated in the backplane.
• When removing a TRIP, use the ejectors to release the bus connectors from the backplane. Use
the handle to pull the TRIP out slowly while keeping your other hand underneath the carrier to
guide it straight out of the slot.
• Handle carriers by the handles and carrier edges only; avoid touching the board or connectors.
• Place a removed TRIP board-side-up on an antistatic surface or in a static shielding bag. If you
plan to return the component to the factory, immediately place it in a static shielding bag.
• Avoid contact between the TRIP and clothing. The wrist straponly protectsthe boardfrom ESD
voltages on the body; ESD voltages on clothing can still cause damage.
• Never attempt to remove the TRIP printed circuit board from the metal interface processor
carrier.
Caution Periodically check the resistance value of the antistatic strap. The measurement should
be between 1 and 10 megohms.
12 Token Ring Interface Processor (TRIP) Installation and Configuration
Online Insertion and Removal—An Overview
Online insertion and removal (OIR) allows you to remove and replace interface processors while the
system is operating; you do not need to notify the software or shut down the system power. This
section describes the mechanical functions of the systemcomponents and stresses theimportance of
following the correct procedures to avoid unnecessary restarts or card failures. This section is for
background information only. Subsequent sections provide specific procedures for removing and
installing a TRIP. All CxBus and CyBus interface processors support OIR
Each processor module contains a bus connector with which it connects to the system backplane.
The busconnector is aset of tiered pins, in three lengths. The pins send specificsignals 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 you insert
an interface processor, the longest pins make contact with the backplane first, and the shortest pins
makecontact last. The system recognizes the signals and the sequence in which it receives them. The
system expects to receive signals from the individual pins in this logical sequence, and the ejector
levers help to ensure that the pins mate in this sequence.
When you remove or insert an interface processor, the backplane pins send signals to notify the
system, which then performs as follows:
1 Rapidly scans the backplane for configuration changes and does not reset any interfaces.
Installation Prerequisites
2 Initializes all newly inserted interface processors, noting any removed interfaces and placing
them in the administratively shutdown state.
3 Brings all previouslyconfigured interfaceson theinterface processorback tothe state they were
in when they were removed. Any newly inserted interfaces are put in the administratively shut
downstate, as if theywere present (butunconfigured) at boot time. If a similar interface processor
type has been reinserted into a slot,then its ports are configuredand brought online upto the port
count of the original interface processor.
OIR functionality enables you to add, remove, or replace interface processors with the system
online, which provides a method that is seamless to end users on the network, maintains all routing
information, and ensures session preservation.
When you insert a new interface processor, the system runs a diagnostic test on the new interfaces
and compares them to the existing configuration. If this initial diagnostic test 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 interface processor is faulty and if normal system operation is possible.
If the second diagnostic test passes, which indicates that the system is operating normally and the
newinterface processoris faulty,the systemresumes normal operationbut leaves the new interfaces
disabled. If the seconddiagnostic testfails, the systemcrashes, whichusually indicatesthat thenew
interface processor has created a problem on the bus and should be removed.
The system brings online only interfaces that match the current configuration and were previously
configured as up; all other interfaces require that you configure them with the configure command.
On interface processors with multiple interfaces, only the interfaces that have already been
configured are brought online. The new interface remains in the administratively shutdown state
until you configure it and bring it online.
Caution While the TRIP supports OIR, the system may indicate a hardware failure if you fail to
follow proper procedures.
Token Ring Interface Processor (TRIP) Installation and Configuration 13
Installation Prerequisites
The function of the ejector levers (see Figure 10) is to align and seat the card connectors in the
backplane.Failure to use the ejectors and insert theinterface processor properly can disrupt the order
in which the pins make contact with the backplane. Follow the TRIP installation and removal
instructions carefully, and reviewthe following examples of incorrect insertion practices and results:
• Using the handle to forcethe interfaceprocessor all theway into theslot can popthe ejectors out
• Using the handle to force or slam the interface processor all the way into the slot can also damage
• When using thehandle (ratherthan the ejectors) to seatthe interfaceprocessor in the backplane,
• Using the handle to insert or remove an interface processor, or failing to push the ejectors to the
of their springs. Ifyou thentry touse theejectors toseat theinterface processor, the first layer of
pins (which are already mated to the backplane) can disconnect and then remate with the
backplane, which the system interprets as a board failure.
the pins on the board connectors if they are not aligned properly with the backplane.
you may need to pull the interface processor back out and push it in again to align it properly.
Even if the connector pins are not damaged, the pins mating with and disconnecting from the
backplane will cause the system to interpret a board failure. Using the ejectors ensures that the
board connector mates with the backplane in one continuous movement.
full 90-degree position, can leave some (not all) of the connector pins mated tothe backplane, a
state which will hang the system. Using the ejectors and making sure that they are pushed fully
into position ensures that all three layers of pins are mated with (or free from) the backplane.
It is alsoimportant to use the ejectorlevers when removingan interfaceprocessor to ensure that the
board connector pins disconnect from the backplanein the logical sequence expectedby the system.
AnyRP,SP, or interface processor that is only partially connectedto the backplane can hang the bus.
Detailed steps for correctly performing OIR are included with the following procedures for
installing and removing a TRIP.

A disposable ESD-prevention wrist strap is includedwith allnew components and upgradekits; use
it to prevent damage to equipment from electrostatic discharge.
• If you are replacing the existing TRIP in your system, you also need a replacement TRIP.
• A large Phillips or flat-blade screwdriver for the captive installation screwsthat secure the TRIP
in its slot.
• Antistatic mat or antistatic foam (only if you are replacing components such as the ROM)
Installation
The following sections describe the procedures for removing or installing a TRIP in a Cisco 7000
and Cisco 7500 series router.The OIR function allows you to install and removea TRIP without first
shutting down the system; however, you must follow the instructions carefully. Failure to insert the
TRIP properly can cause system error messages indicating a board failure. For a complete
description of OIR,refer to the section “OnlineInsertion and Removal—An Overview” on page 13.
Each unused interface processor slot contains an interface processor filler (which is an interface
processor carrier without an interface board) to keep dust out of the chassis and to maintain proper
air flow through the interface processor compartment. If you are installing a new TRIP that is not a
replacement, you must firstremove the interfaceprocessor fillerfrom anunused slot,proceed tothe
section “Removing an Interface Processor Filler.” If you are replacing a TRIP,proceed to the section
“Removing a TRIP.”
Removing an Interface Processor Filler
Select an unused interface processor slot for the new TRIP and remove the interfaceprocessor filler
as follows:
Step 1 Choose an available slot for the TRIP and ensure that there is enough clearance to
accommodate any interface equipment that you will connect directly to the ports (for
example, transceivers that connect directly to the ports overlap equipment on adjacent
interface processors).
Step 1 Use a screwdriver to loosen the captive installation screwson the interface processor filler.
(See Figure 10.)
Step 2 Place your thumbs on both ejectors and simultaneously pull them both outward to release
the TRIP from the backplane connector (in the opposite direction from that shown in
Figure 10c).
Step 3 Grasp the handle with one hand and pull the filler straight out of the slot, keeping your other
hand under the carrier to guide it. (See Figure 11.) Keep the carrier parallel to the
backplane.

Removing a TRIP
Installation
Step 4 Store the interface processor filler for future use.
To help preventdust and contaminants from entering the chassis, do not leavethe interface processor
slot open. Immediately proceed to the section “Installing a TRIP” on page 18.
The TRIP supports OIR; therefore, you need not shut down the interface or the system powerwhen
removing a TRIP. If you are replacing a failedTRIP, remove the existing board first, then replace the
new TRIP in the same slot.
Figure 11 shows proper handling of an interface processor for installation in the Cisco 7010 and
Cisco 7505 models. The processorslots are orientedhorizontally in theCisco 7010 and Cisco 7505,
and vertically in the Cisco 7000, Cisco 7507, and Cisco 7513.
To remove a TRIP, follow these steps:
Step 1 Disconnect the all cablesfrom theTRIP ports (if you are movingthe TRIPto anotherport,
this step is not necessary).
Step 2 Use a screwdriver to loosen the captive installation screws at both ends of the TRIP.
(See Figure 10.)
Caution Always use the ejector levers to remove or install the TRIP. Failure to do so can cause
erroneous system error messages indicating a board failure.

Step 3
Place your thumbs on the ejector levers and simultaneously pull both of the ejectors
outward (in the opposite direction from that show in Figure 10c) to release the TRIP from
the backplane connector.
Step 4 Use the handle to carefully pull the TRIP straight out of the slot, keeping your other hand
under the carrier to guide it. (See Figure 11.) Keep the TRIP parallel to the backplane.

Installation
Installing a TRIP
Step 5 Place the removedTRIP on an antistatic mat or foampad, or place itin an antistatic bagif
you will return it to the factory.
Step 6 If the interface processor slot is to remain empty, install an interface processor filler
(MAS7K-BLANK) to keepdust out of the chassis and to maintain proper air flow through
the interface processor compartment.
To help preventdust and contaminants from entering the chassis, do not leavethe interface processor
slot open. Immediately proceed to the section “Installing a TRIP” on page 18.
The TRIP slides into the open interface processor slot and directly to the backplane. The interface
processors are keyedto guide pins on the backplane, so the TRIP can be installed only in an interface
processor slot. (See Figure 5, Figure 6, Figure 7, Figure 8, or Figure 9, depending on your chassis.)
Figure 10 shows the functional details of inserting an interface processor and using the ejectors.
Figure 11 shows proper handling of an interface processor during installation.
Caution Remove or insert onlyone interfaceprocessor at a time. Allow at least 15 seconds forthe
system to complete its discovery and initialization tasks before removing or inserting another
interface processor. Disrupting the sequence before the system has completed it verification can
cause the system to interpret hardware failures.
The TRIP supports ring speeds of 4 and 16 Mbps. Follow these steps to install a TRIP:
Step 1 Ensure the console terminal is connected to the RP (or RSP) Console port and that the
console is turned ON.
Step 2 Hold the TRIP handle with one hand, and place your other hand under the carrier to support
the TRIP and guide it into the slot. (See Figure 11.) Avoid touching the card or any
connector pins.
Caution To prevent ESD damage, handle interface processors by the handles and carrier edges
only.
Step 3 Place the back of the TRIP in the slot and align the notch on the carrier with the groove in
the slot. (See Figure 10.)
Step 4 While keeping the TRIP parallel to the backplane, carefully slide it into the slot until the
back of the faceplate makes contact with the ejector levers, then stop. (See Figure 10b.)
Caution Always use the ejector levers when installing or removingprocessor modules. A module
that is partially seated in the backplane will cause the system to hang and subsequently crash, and
shoving or slamming the interface processor into the slot can damage the backplane and connector
pins.
Step 5 Using your thumbs, simultaneously push both ejectors inward until the TRIP is pushed
entirely into its slot. (See Figure 10c.)
Step 6 Tighten both of the captive installation screws.

Step 8
Check the status of the interfaces as follows:
• If this installation was a replacement TRIP,use the show interfaces orshow controller
[type] command to verify that the system has acknowledged the new interfaces and
brought them up.
• If the interfacesare new, use the configure command or the setup command facility to
configure the new interface(s) (this does not have to be done immediately, but the
interfaces will not be available until you configure them).
Checking the Installation
The TRIP contains one enabled LED and a row of three LEDs for each Token Ring interface.
(See Figure 11). The row of three LEDs indicate the speed (4 or 16 Mbps) of the interface and
whether the interface is inserted in the ring.
When you install the TRIP in an interface processor slot and turn ON the power (if the power was
turned off), the following events occur:
• The enabled LED lightsto indicatethat the TRIP is operational and that itis poweredup. It does
not mean that the interface ports are functional orenabled. An error condition exists if the TRIP’s
enabled LED is not litafter power up or after initialization. If this happens, check that the TRIP
is installed correctly. If a second power up attempt also fails, contact a customer service
representative.
• The horizontal set of LEDs flash for about four or five seconds and are then turned off. These
LEDs are turned on again after you configure each Token Ring interface as described in the
section “Configuring the Interfaces” on page 20.

Configuring the Interfaces
You can modify the startup configuration for Cisco 7000 series and Cisco 7500 series routers
through the software command interpreter called EXEC. To configure the interfaces for interface
processors, you can use either one of the following EXEC commands:
setup
configure
The setup command facility can be used after first time startup to make basic changes at any time.
The changes you make will affect only the changedelements’ current memoryvalues that are stored
in nonvolatile memory.

The privileged EXEC command configureenables you to perform advancedconfigurations suchas
specifying interfaces.
The EXEC interprets the commands you enter and carries out the corresponding operations. Youcan
list available EXEC commands by entering a question mark (?). You also canenter a question mark
to obtain more information about commands. For example, enter terminal ? to obtain a list of
terminal commands or show ? to obtain a list of show commands.
Using the EXEC Command Interpreter
Before you usethe setupor the configure command,you must have privilegedaccess to the EXEC
command interpreter. The system promptfor theprivileged level ends witha poundsign (#) instead
of an angle bracket (>).
The EXEC enable command allows access to the privilegedlevel, prompting for a password if one
has been set with the enable-password configuration command.
Follow these steps to enter the privileged level of the EXEC.
Step 1 At the EXEC prompt for a router, enter the enable command:
Router> enable
The EXEC prompts you for a privileged level password:
Password:
Step 2 Enter the password.
For security purposes, the password is not displayed. (Also note that the password is case
sensitive). When you enter the correct password, the system displays the privileged mode
system prompt:

20 Token Ring Interface Processor (TRIP) Installation and Configuration
To configure TokenRing interfaces using the setup EXEC commandfacility,follow the instructions
in the section “Using the Setup Command” on page 21. To configure the Token Ring interfaces by
using the configure EXEC command, follow the instructions in the section “Using the Configure
EXEC Command” on page 22.
Using the Setup Command
The setup command facility identifies all interfaces (including the Token Ring interfaces for the
portson the TRIP) that are installed and prompts you forconfiguration information for each installed
interface. When you finish configuring one interface, the setup command facility prompts you for
the next, continuing until each interface has been configured.
When you enter the setup command facility after first time startup, you must run through the entire
dialog until you come to the interface you want to change. Note that when you use the setup
command after first time startup, the default values indicated within the brackets in the System
Configuration Dialog are the values last set using the setup command facility or left as defaults.
Afteryou choose to continue with the setupcommand (by answering yes to the system configuration
dialog prompt), the remainder of the script is the actual configuration process. The dialog prompts
you first for global system parameters, then for configuration information for each interface. The
existing configuration is displayed as the default, in brackets ([ ]), at the end of each prompt. Press
Return to accept the default settings.
Configuring the Interfaces
Note After you start the setup command facility, the system runs through the entire configuration
process; you cannot quit out of it. To make a change or correct a mistake, press the Return key at
each prompt, answer no when asked if you want to save the configuration, and restart the setup
facility.
Step 1 After you access the privileged level of the EXEC, as described in the section “Using the
EXEC Command Interpreter” on page 20, enter the setup command to begin the setup
facility:
Router# setup
Step 1 The following script isdisplayed on the screen, with the nameof your router as the default
in the brackets.
-System Configuration DialogAt any point you may enter a question mark ‘?’ for help.
Refer to the ‘Getting Started’ Guide for additional help.
Default settings are in square brackets ‘[]’.
Continue with configuration dialog? [yes]:
(Use Ctrl-c to abort configuration at any prompt)
Configuring global parameters:
Enter host name [Router]: sandbox
Step 2 To accept the default and keep the router name, press Return. (If you do want to change
the name of the router, enter the new name before pressing Return.)

Configuring the Interfaces
Step 3 Proceed through the remainder of the global parameter prompts, using the Return key to
Step 4 To accept thedefault at each prompt and retainthe existing configuration information, press
accept the defaults.
After the global parameters are configured, the system prompts you for interface
configurationinformation, one interface at a time. Followingis a partial display ofthe script
for a previously configured interface:
Configuring interface parameters:
Configuring interface Token Ring0:
Is this interface in use [yes]:
Tokenring ring speed (4 or 16) [16]
Configure IP on this interface? [yes]:
IP address for this interface: 131.108.6.67
(remainder of display text omitted)
the Return key. When you reach the scripts for configuring new interfaces, enter the new
configuration information at each prompt.
When all interfaces are configured, the system displays the entire configuration script
followed by a prompt for which there is no default (you must enter yes or no):
Use this configuration [yes/no]:
Step 5 To use the configuration you created, enter yes. To discard the configuration file and begin
the configuration process again, enter no.
If you entered yes at the prompt, the following message displays:
Press RETURN to get started!
The configuration process is complete. Proceed to the section “Checking the Configuration” on
page 24. It provides show commands you can use to display and verify the configuration
information.
Using the Configure EXEC Command
The configureEXEC command allows you to configure the interfaces for interface processors in the
Cisco 7000 series and Cisco 7500 series. At the privileged command level,enter the ? command to
display a list of privileged level EXEC commands.
To display information about the interface, including the software and hardware versions and the
controller status, use the show controllercxbus command. Todisplay statistics about the interfaces,
use the show interfaces command.
Identifying Slot and Interface Numbers
Use the show interfaces command to determine which interfaces you need to configure and to
determine the interface type, slot numbers, and port numbers.
The number of ports you configure depends on the number of ports available on the interface
processor. For example, if you install a TRIP with four ports in slot 0, configure the Token Ring
interface for each of these ports as follows: 0/1, 0/2, 03/ and 0/4. The maximum number of ports
available on the TRIP is four.
After identifying the port numbers for the interfaces, configure the interfaces as described in the
section “Basic Configuration Guidelines” on page 23.
22 Token Ring Interface Processor (TRIP) Installation and Configuration
Basic Configuration Guidelines
Followingare instructions fora basic configuration: enabling aninterface and specifying IProuting.
You might also need to enter other configuration subcommands, depending upon the requirements
for your system configuration. (Configuration subcommands are described in the Router Products
Configuration Guide, available on UniverCD or in print.)
Step 1 After you access the privileged level of the EXEC as described in the section “Using the
EXEC Command Interpreter” on page 20, enter the configure command:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 2 Specify the first Token Ring interface to configure by entering the subcommand interface
type slot/port. For example, if you are configuring the Token Ring interface 0 for a TRIP
installed in slot 4, enter the following command:
Router(config)# interface tokenring 4/0
Step 3 If IP routing isenabled onthe system, you can assign an IP addressand subnetmask tothe
interface with the ip address configuration subcommand as follows:
Router(config-int)# ip address
Step 4 Change the default shutdown state and enable the interface:
Router(config-int)# no shutdown
Configuring the Interfaces
ip address subnet mask
When you enable the interface by using the no shutdown command, the LED for 4 Mbps
or 16 Mbps is turned on after about 5 seconds. The IN RING LED for that interface is
turned on about 5 to 18 seconds later, when the port is initialized and is connected to the
ring.
Step 5 Enter any additional configuration subcommands required.
Step 6 Repeat steps 2 through 5 for each new interface.
Step 7 When all new interfaces are configured, press Ctrl-Z (hold the Control key down and press
the Z key).
Step 8 Write the new configuration to memory by entering the following:
Router# copy running-config startup-config
[OK]
Router#
Step 9 Enter quit to exit the configuration mode:
Router# quit
You have now completed configuring the Token Ring interfaces. Check the configuration as
described in the section “Checking the Configuration.”
Token Ring Interface Processor (TRIP) Installation and Configuration 23
Checking the Configuration
Checking the Configuration
After configuring the new interface(s) using either the setup command or the configure command,
use the EXEC show commands to display status information.
Step 1 To display the current system configuration file, enter the show configuration command:
Router# show configuration
The configuration file for the router is displayed. Check the Token Ring configuration
information in the display.
Step 2 To display and check all interfaces, enter the following command:
Router# show interfaces
Each interface is listed along with itsassigned IP address. Verifythat each new TokenRing
interface appears.
Step 3 To obtain detailed status information about a specific Token Ring interface, specify the
interface with the following command:
Router# show interface tokenring
Detailed information aboutthe interface is displayed. The first line ofdisplay specifies the
interfacealong with its slot and port number.It indicates whether the hardwareis functional
and if the line protocol is up or down. If the line protocol is down (and you did not
administratively shut it down), or if the hardware is not functioning properly, ensure that
the network interface is properly connected and terminated. For explanations of the
displayed information, refer to the Router Products Command Reference and the Router
Products Command Summary publications.
slot/port
Step 4 To display the current internal status of theprocessors, use the show controllercommand:
Router# show controllers token
The display lists the interfaces connected to each processor and indicates whether the
system has identified your new interface. It does not indicate the state of the line or the
protocol.
This completes theinstallation and configuration procedure for the TRIP andassociated equipment.
24 Token Ring Interface Processor (TRIP) Installation and Configuration
Upgrading Microcode
Depending on how it is configured, the Cisco 7000 series router allows the Switch Processor (SP)
and interface processors to use updated microcode that is available either in Flash memory on the
Route Processor (RP) or on the onboard ROM for each processor. The Cisco 75000 series routers
allow the interface processors to use updated microcode that is available either in Flash memory on
the Route Switch Processor (RSP) or on the onboard ROM for each processor.
The router supports downloadable microcode, which enables you to upgrade microcode versions
without having to physically replace the ROMs on the boards. You can download new microcode
versions, store multiple versions in Flash memory, and boot from them, just as you can with the
system software images. System software upgrades can also contain upgraded microcode images,
which will load automatically when the new software image is loaded.
Withdownloadable microcode, youshould never need toreplace themicrocode ROM on the board.
If, however, replacement is necessary in the future, specific instructions will also be provided with
the replacement component in an upgrade kit.
Downloading Microcode to Flash Memory
You can download microcode to Flashmemory bycopying theTFTP imageof a microcode version
to Flash memory.When the microcode version is available in Flash memory,you can boot therouter
either automatically or manually from Flash memory. Follow these steps to copy a microcode
version from the TFTP server to Flash memory:
Upgrading Microcode
Step 1 To display the total amount of Flash memory present, its location, any files that currently
might exist in Flash memory and their size, and the amount of Flash memory remaining,
use the show flash command.
The following type of output is displayed:
4096K bytes of flash memory on embedded flash (in RP1).
file offset length name
0 0x40 53330 trip1-0
1 0xD0D4 51432 sp1-0
[4089412/4194304 bytes free]
Note Before you copy a file to Flash memory, be sure there is ample space available in Flash
memory. Compare the size of the file you want to copy to the amount of available Flash memory
shown. If the space available is less than the space required by the file you want to copy, the copy
process will continue, but the entire fill will not be copied into Flash.
Step 2 After you verify that there is sufficient space available in Flash memory for new images,
enter the following command:
Router# copy tftp flash
Step 3 Enter the IP address of the remote host:
IP address or name of remote host [255.255.255.255]?
ip address
Step 4 Enter the name of the file you want to copy to Flash:
Name of file to copy ?
file name
The format of the file name is the name of the interface processor followed by the version
number (for example, trip1-0).
Token Ring Interface Processor (TRIP) Installation and Configuration 25
Upgrading Microcode
Step 5 Confirm that you want the file copied into Flash:
Copy trip1-0 from 131.108.13.111 into flash memory? [confirm] yes
Step 6 If you do not want the other microcode files in Flash memory erased, enter no
OR
If you want Flash erased, enter yes.
Erase flash before writing? [confirm] no
If you answered yes, the Flash memory is erased, and the TRIP microcode is copied to
Flash memory. Output similar to the following is displayed:
Zeroing bank...zzzzzzzzzzzzzzzz
Verify zeroed...vvvvvvvvvvvvvvvv
Erasing bank...eeeeeeeeeeeeeeee
Loading from 131.108.1.111: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 1906676/4194240 bytes]
Verifying via checksum...
Flash verification successful. Length = 1906676, checksum = 0x12AD
If you answered no, theTRIP microcode iscopied to Flashmemory without any erasureof
existing files in Flash.
Step 7 Verify that the microcode has been copied to Flash memory:
Router# show flash
The following type of output is displayed:
4096K bytes of flash memory on embedded flash (in RP1).
file offset length name
0 0x40 53330 trip1-0
1 0xD0D4 51432 sp140-34
[4089412/4194304 bytes free]
Step 8 If you want the TRIP to use the microcode in Flash memory immediately, enter the
following commands at the router prompt:
Router# microcode trip flash
Router# microcode reload
microcode file name
The microcode reload command immediately enables the TRIP to use the specified
microcode file.
Step 9 To ensure that the new microcode is used by the TRIP after a system reboot, add the
microcode commands to the configuration file. To access the configuration file, enter the
following command:
Router# configure terminal
Step 10 Add the following commands to the configuration file:
microcode trip flash
microcode reload
microcode file name
Step 11 To exit the configuration mode, press Ctrl-Z.
Step 12 To write the updated configuration file to the NVRAM, enter the following command:
Router# copy running-config startup-config
26 Token Ring Interface Processor (TRIP) Installation and Configuration
Upgrading Microcode
Step 13 Verify that the correct microcode version is available in Flash memory:
Router# show controllers token
You have now completed downloadingmicrocode tothe Flashmemory, downloaded the microcode
tothe TRIP,added themicrocode commands to the configuration file, and updated the NVRAMwith
the new configuration file.
If any of the interfaces fail to return to their previous state, refer to the troubleshooting procedures
in the hardware installation and maintenance publication appropriate to your chassis model.
