Product Description  
When a Token Ring interface is 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—When lit, indicates that the interface is currently active and inserted into the ring. 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 access unit (MSAU) to provide the interface between  
the TRIP Token Ring interfaces and the external ring, and a Token Ring lobe cable between each  
TRIP port and the MAU or 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 any port using the configuration command ring-speed n, where n is  
the speed (4 or 16) in Mbps. The speed of each Token Ring port must match the speed 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.  
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. If the port is set for a different speed, it will cause the ring to beacon,  
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) receptacles that require Type 1 or 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’s Token Ring Network, which IBM developed 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 are token passing networks, which move 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 specify any topology, 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 address and  
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  
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  
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.  
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 strap only protects the board from 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.

Installation Prerequisites  
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 system components and stresses the importance 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 bus connector is a set of tiered pins, in three 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 you insert  
an interface processor, 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 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
2
Rapidly scans the backplane for configuration changes and does not reset any interfaces.  
Initializes all newly inserted interface processors, noting any removed interfaces and placing  
them in the administratively shutdown state.  
3
Brings all previously configured interfaces on the interface processor back to the state they were  
in when they were removed. Any newly inserted interfaces are put in the administratively shut  
down state, as if they were present (but unconfigured) at boot time. If a similar interface processor  
type has been reinserted into a slot, then its ports are configured and brought online up to 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  
new interface processor 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  
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  
backplane. Failure to use the ejectors and insert the interface processor properly can disrupt the order  
in which the pins make contact with the backplane. Follow the TRIP installation and removal  
instructions carefully, and review the following examples of incorrect insertion practices and results:  
Using the handle to force the interface processor all the way into the slot can pop the ejectors out  
of their springs. If you then try to use the ejectors to seat the interface 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.  
Using the handle to force or slam the interface processor all the way into the slot can also damage  
the pins on the board connectors if they are not aligned properly with the backplane.  
When using the handle (rather than the ejectors) to seat the interface processor in 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.  
Using the handle to insert or remove an interface processor, or failing to push the ejectors to the  
full 90-degree position, can leave some (not all) of the connector pins mated to the 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 also important to use the ejector levers when removing an interface processor to ensure that the  
board connector pins disconnect from the backplane in the logical sequence expected by the system.  
Any RP, SP, or interface processor that is only partially connected to the backplane can hang the bus.  
Detailed steps for correctly performing OIR are included with the following procedures for  
installing and removing a TRIP.

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 remove a 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  
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 first remove the interface processor filler from an unused slot, proceed to the  
section “Removing an Interface Processor Filler.” If you are replacing a TRIP, proceed to the section  
Removing an Interface Processor Filler  
Select an unused interface processor slot for the new TRIP and remove the interface processor 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 screws on the interface processor filler.  
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  
Step 3 Grasp the handle with one hand and pull the filler straight out of the slot, keeping your other  
backplane.

Installation  
Step 4 Store the interface processor filler for future use.  
To help prevent dust and contaminants from entering the chassis, do not leave the interface processor  
Removing a TRIP  
The TRIP supports OIR; therefore, you need not shut down the interface or the system power when  
removing a TRIP. If you are replacing a failed TRIP, 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 processor slots are oriented horizontally in the Cisco 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 cables from the TRIP ports (if you are moving the TRIP to another port,  
this step is not necessary).  
Step 2 Use a screwdriver to loosen the captive installation screws at both ends of the TRIP.  
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  
Step 5 Place the removed TRIP on an antistatic mat or foam pad, or place it in an antistatic bag if  
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 keep dust out of the chassis and to maintain proper air flow through  
the interface processor compartment.  
To help prevent dust and contaminants from entering the chassis, do not leave the interface processor  
Installing a TRIP  
The TRIP slides into the open interface processor slot and directly to the backplane. The interface  
processors are keyed to 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 only one interface processor at a time. Allow at least 15 seconds for the  
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  
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  
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 removing processor 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  
Step 6 Tighten both of the captive installation screws.

Checking the Installation  
Step 7 Attach network interface cables or other connection equipment to the interface ports.  
Figure 12 Token Ring Connections  
TRIP  
MAU  
Step 8 Check the status of the interfaces as follows:  
If this installation was a replacement TRIP, use the show interfaces or show controller  
[type] command to verify that the system has acknowledged the new interfaces and  
brought them up.  
If the interfaces are 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 lights to indicate that the TRIP is operational and that it is powered up. It does  
not mean that the interface ports are functional or enabled. An error condition exists if the TRIP’s  
enabled LED is not lit after 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  
Token Ring Interface Processor (TRIP) Installation and Configuration 19  
 
   
Configuring the Interfaces  
Figure 13 TRIP LEDs  
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 changed elements’ current memory values that are stored  
in nonvolatile memory.  
The privileged EXEC command configure enables you to perform advanced configurations such as  
specifying interfaces.  
The EXEC interprets the commands you enter and carries out the corresponding operations. You can  
list available EXEC commands by entering a question mark (?). You also can enter 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 use the setup or the configure command, you must have privileged access to the EXEC  
command interpreter. The system prompt for the privileged level ends with a pound sign (#) instead  
of an angle bracket (>).  
The EXEC enable command allows access to the privileged level, 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  
 
   
Configuring the Interfaces  
To configure Token Ring interfaces using the setup EXEC command facility, 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  
Using the Setup Command  
The setup command facility identifies all interfaces (including the Token Ring interfaces for the  
ports on the TRIP) that are installed and prompts you for configuration 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.  
After you choose to continue with the setup command (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.  
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 is displayed on the screen, with the name of your router as the default  
in the brackets.  
-System Configuration Dialog-  
At 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.)  
Token Ring Interface Processor (TRIP) Installation and Configuration 21  
 
 
Configuring the Interfaces  
Step 3 Proceed through the remainder of the global parameter prompts, using the Return key to  
accept the defaults.  
After the global parameters are configured, the system prompts you for interface  
configuration information, one interface at a time. Following is a partial display of the 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)  
Step 4 To accept the default at each prompt and retain the existing configuration information, press  
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!  
page 24. It provides show commands you can use to display and verify the configuration  
information.  
Using the Configure EXEC Command  
The configure EXEC 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 controller cxbus command. To display 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  
22 Token Ring Interface Processor (TRIP) Installation and Configuration  
 
 
Configuring the Interfaces  
Basic Configuration Guidelines  
Following are instructions for a basic configuration: enabling an interface and specifying IP routing.  
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  
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 is enabled on the system, you can assign an IP address and subnet mask to the  
interface with the ip address configuration subcommand as follows:  
Router(config-int)# ip address ip address subnet mask  
Step 4 Change the default shutdown state and enable the interface:  
Router(config-int)# no shutdown  
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  
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 its assigned IP address. Verify that each new Token Ring  
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 slot/port  
Detailed information about the interface is displayed. The first line of display specifies the  
interface along with its slot and port number. It indicates whether the hardware is 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.  
Step 4 To display the current internal status of the processors, use the show controller command:  
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 the installation and configuration procedure for the TRIP and associated equipment.

Upgrading Microcode  
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.  
With downloadable microcode, you should never need to replace the microcode 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 Flash memory by copying the TFTP image of a microcode version  
to Flash memory. When the microcode version is available in Flash memory, you can boot the router  
either automatically or manually from Flash memory. Follow these steps to copy a microcode  
version from the TFTP server to Flash memory:  
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  
53330  
51432  
name  
trip1-0  
sp1-0  
0
1
0x40  
0xD0D4  
[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).

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, the TRIP microcode is copied to Flash memory without any erasure of  
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  
0

name  
trip1-0  
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 microcode file name  
Router# microcode reload  
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 file name  
microcode reload  
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 downloading microcode to the Flash memory, downloaded the microcode  
to the TRIP, added the microcode commands to the configuration file, and updated the NVRAM with  
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.
