Troubleshooting the Cisco ONS 15104

Regardless of whether you locate the source of your problem, contact a Cisco customer service representative for information on how to proceed. Before you call technical support, have the following information ready:

Cisco ONS 15104 type and serial number
Maintenance contract number or warranty information
Date you received the new Cisco ONS 15104
Software release level and hardware configuration
System software configuration
Brief description of the problem you are having
Brief explanation of steps you have taken to isolate the problem

Isolating the Problem

The key to troubleshooting this system is to isolate the problem to a specific subsystem. If you compare what the system is doing to what it should be doing, the task of isolating a problem is greatly simplified.

When problem solving, consider the following subsystems of the Cisco ONS 15104:

Power system—This subsystem includes the power supply and the cable.
Cooling system—The fans should go on when power is supplied. The air intake vents and exhaust vents must have adequate ventilation.
Network interfaces—Use the LEDs related to the network interfaces (Ethernet, SDCC0, and SDCC1) to help identify a failure. For complete information on LED indicators, refer to the section "Cisco ONS 15104 Alarms and Alerts," later in this chapter.
System cables—This includes all of the interface cables that connect the Cisco ONS 15104 to other devices.

Instructions for troubleshooting these systems are covered in the following sections.

Verifying Network Connectivity

After you install and configure the Cisco ONS 15104, you can use the following commands in user EXEC mode to verify network connectivity:

telnet—Logs in to a remote node
ping—Sends a special datagram to the destination device, then waits for a reply datagram from that device
trace—Discovers the routes that packets take when traveling from one interface to another

If there is a problem with network connectivity, refer to the "Cisco ONS 15104 Alarms and Alerts" section.

Reading the Front Panel LEDs

The LEDs provide the activity status of the interfaces to which they correspond. If an LED is not on when the interface is active and the interface is correctly connected, this may indicate a problem. If an interface is extremely busy, its LED will always be on. See Figure A-1 for locations of the LEDs on the Cisco ONS 15104.

Figure A-1: Cisco ONS 15104 LED Indicators (Front-Panel View)

Table A-1 shows the types of LEDs that will display on the front of the Cisco ONS 15104
when you boot up.

Table A-1: Cisco ONS 15104 Front Panel LED Indicators

Indicator	Quality	System Ready	System Fail	Description
Activity (Ethernet)	1	Green	OFF	Traffic on ethernet port
Activity (console)	1	Green	OFF	Data sent/received on console port
SONET Rx	2	Green	OFF	Cisco ONS 15104 is receiving SONET/SDH frames correctly.
System Fail	1	Off	Red	Software controlled by decoder
System Ready	1	Green	OFF/Flashing	Software controlled by decoder in ROM monitor mode
Power	1	Green	OFF	Main power supply okay

If the SONET Rx LED is not illuminated, verify the following conditions:

All power cords and data cables are firmly connected at both ends.
The OC-48 line cards connected to the Cisco ONS 15104 are firmly seated and secured to the card cage.
All the devices attached to the Cisco ONS 15104 are properly connected.
All the devices that are locally attached to the Cisco ONS 15104 are compatible, and you are using the appropriate single-mode long-reach cable.
The Tx port of the OC-48 line card is connected to the Rx port on the Cisco ONS 15104.

To verify that the Cisco ONS 15104 is connected correctly, perform the following procedure:

Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system registers the Cisco ONS 15104. If both of the following conditions are valid, the system should recognize the interface, but show the interface configured as down:

The Cisco ONS 15104 is correctly connected to the OC-48 line card in the GSR chassis and receiving power.
A valid release of Cisco ONS 15104 software is loaded and running.

Step 2 When the reinitialization is complete, verify that the System Ready LED on the
Cisco ONS 15104 is on and remains on.
Upon startup, if a failure occurs, the red system failure LED will come on, and the green system ready LED will flash to indicate that a failure has occurred.

Step 3 Verify the temperature of the Cisco ONS 15104's location.
If the Cisco IOS software detects an over temperature condition, the system fail LED will light up. The over temperature shutdown alarm is enabled when the operating temperature exceeds 32 to 104ºF (0 to 40ºC). (For details, see the following section "Troubleshooting the Power and Cooling Systems.")

Step 4 Check to see if any voltage-related alarms were reported. (See the "Cisco ONS 15104 Alarms and Alerts" section.)

Step 5 Use the show interfaces command to verify the status of the Cisco ONS 15104's network interfaces. (If the interface is not configured, you must use the procedures in "Configuring the Cisco ONS 15104.")

Step 6 Use the show controller regen x (x=0 or 1) command to check the SONET/SDH alarms. The LOS alarm means that there is no signal on the fiber line or that the fiber is not connected, and it will cause the SONET Rx green LED to turn off.

If an error message displays on the console terminal, refer to the appropriate reference publication for error message definitions for your release of Cisco IOS software. If you experience other problems that you are unable to solve, contact a Cisco customer service representative for assistance.

Troubleshooting the Power and Cooling Systems

Check the following items to help isolate the problem:

The Power and System Ready LEDs are on (see Figure A-1), but the system is not working.
- Check the fans by listening to see if they are all operating.
- Check the PC terminal output to see if any temperature alarms are automatically raised to determine if a problem is emerging. Alarms are reported to the console and, if configured, to the syslog server. Enter the show env command to show the status of the board temperature. If an over temperature condition exists, take steps to cool off the environment by turning up the air conditioning, if possible. Report the problem to your system administrator, but do not shut anything down.
The system shuts down after being on for a short time.
- Check the environmental site requirements in "Configuring Equipment Racks," and ensure that the Cisco ONS 15104 intake and exhaust vents are clear.
- Suspect a power supply failure.
The system does not boot up, but LEDs are on. Suspect the power supply.
The system partially boots, but LEDs are off. Suspect the power supply.

Troubleshooting the Network Interfaces and Cables

Check for the following symptoms to help isolate the problem:

A network interface is not recognized by the system.
- Check the interface cable connection.
- Check the LED that corresponds to the network interface.
A network interface is recognized, but it will not initialize. Check the interface cable connection.
The system boots, but the console screen is frozen.
- Check the external console connection.
- Verify that the console baud rate is configured properly.
- Suspect the power supply.
The system powers on and boots with a particular interface disabled. Suspect the network interface connection.

Note The fiber-optic connectors must be free of dust, oil, or other contaminants. Carefully clean the fiber-optic connectors using an alcohol wipe or other suitable cleanser.

Cisco ONS 15104 Alarms and Alerts

All status and alarm reports of the Cisco ONS 15104's receiving controller are from the receiving (Rx) fiber-optic connector side. Commands operating on the transmitting controller affect the transmitting (Tx) fiber-optic connector side.

For more information on troubleshooting, contact Cisco Technical Support. See the "Service and Support" section in the Preface.

Recovering Lost Passwords

This section explains how to recover the following types of passwords:

Enable secret password (a very secure, encrypted password). The enable secret password is available on the Cisco ONS 15104 running Cisco IOS Release 12.0T or later.
Enable password (a less secure, nonencrypted password). The enable password is used when the enable secret password does not exist.
Console password. The console password is used to prevent unauthorized users from attempting to change the Cisco ONS 15104 configuration. When a console password is set, you must provide a password to log in to the console and access user EXEC mode.

The key to recovering a lost enable-level password is to set the configuration register so that the contents of NVRAM are ignored (0x142), which allows you to see your password. The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console passwords might be encrypted or clear text.

To recover a lost password, take the following steps:

Step 1 The password recovery procedure requires a system reload. Note that signal regeneration will normally not be affected by this step.

Step 2 Connect a terminal to the console port on the front panel of the Cisco ONS 15104. Make sure the terminal is configured to operate at 9600 Kpbs, 8 data bits, no parity, 2 stop bits.

Step 3 Enter the show version command to display the existing configuration register value. The configuration register value is on the last line of the display. Note whether the configuration register is set to enable Break or disable Break.

The factory-default configuration register value is 0x2102. Notice that the third digit from the right in 0x2102 is 1, which disables Break. If the third digit is not 1, Break is enabled.

Step 4 If the configuration register is set to disable Break:

Enter the reload command from the Cisco IOS software by pressing the Break key (^[) or by sending a Break signal within 60 seconds to enter ROM monitor mode. The ROM monitor prompt then (>) appears.

: The Cisco ONS 15104 resets the configuration register to 0x142. The
Cisco ONS 15104 boots the system image in Flash memory.

Enter the reset command from the ROM monitor prompt.

rommon # >reset
rommon # >

If the configuration register is set to enable Break, press the Break key (^[) or send a Break signal to the Cisco ONS 15104.

Note

Step 5 Enter privileged EXEC mode, then enter the show startup-config command to display the passwords in the configuration file, as in the following example:

Regen> enable password coins
Regen# show startup-config

Step 6 Scan the configuration file displayed for the passwords (the enable and enable secret passwords are usually near the beginning of the file, but the console password is near the end of the file).

An example of the display follows:

Regen# enable secret x xyxyxyxyxyxyxyxyxyxyxyxyxyx

Regen# enable password coins

.

.

line con 0
password coins

Proceed to Step 8 to replace an enable secret, console, or enable password. If there is no enable secret password, note the enable and console passwords, if they are not encrypted, and proceed to Step 9.

Caution Do not take the next three steps unless you determine that you must change or replace the enable, enable secret, or console passwords. Failure to follow the steps as shown might cause you to erase the configuration on the Cisco ONS 15104.

Step 7 Change only the passwords that are necessary for your configuration. The following example shows how to change all three types of passwords in global configuration mode. The first two lines show how to change the enable secret and enable passwords. The last two lines show how to change the console password.

Regen# configure terminal
Regen(config)# enable secret x xyxyxyxyxyxyxyxyxyxyxyxyxyx
Regen(config)# enable password xyxy
Regen(config)# line con 0
Regen(config-line)# password con1
Regen(config-line)# exit
Regen(config)#

For maximum security, be sure the enable secret and enable passwords are different. You can remove individual passwords by using the no form of these commands. For example, enter the no enable secret command to remove the enable secret password.

Step 8 Configure all interfaces to be administratively up.
In the following example, you must enter the no shutdown command to ensure that the Ethernet 0 port is configured to be administratively up:

Regen(config)# interface ethernet 0
Regen(config-if)# no shutdown

Enter the equivalent commands for all interfaces that were originally configured.

Step 9 Set the configuration register to the original value you noted in Step 3 or the factory-default value (0x2102).
The following example shows how to set the configuration register to the factory-default value:

Regen(config-if)# config-register 0x2102

Regen(config-if)#

Step 10 Enter end to exit a configuration mode.

Regen(config-if)# end
Regen#

Caution Do not take the next three steps unless you changed or replaced a password, or you might erase your Cisco ONS 15104 configuration. If there is no enable secret password (or if you skipped Step 7 through Step 8), proceed to Step 14 and log in.

Step 11 Enter the copy running-config startup-config command to save the new configuration to NVRAM.
This command copies the changes you just made to the running configuration to the startup configuration. The following message appears:

Regen# copy running-config startup-config
Building configuration...
[OK]
Regen#

Step 12 Reboot the Cisco ONS 15104:

Regen# reload

Proceed with reload? [confirm]

Step 13 Press Return to confirm.
When the Cisco ONS 15104 reboots it will use the new configuration register value you set in Step 9.

Step 14 Log in to the Cisco ONS 15104 with the new or recovered password.

Downloading Cisco IOS Software

This section describes six methods that you can use to download Cisco IOS software images in ROM monitor mode:

Using a Local TFTP Server

If the Ethernet port is configured, you can download a Cisco IOS software image in privileged EXEC mode from a local TFTP server.

To configure the Cisco ONS 15104 to download images through the Ethernet port:
- Replace filename with the filename of the Cisco IOS software image.
- Replace ipaddress with the IP address of the TFTP server:

Regen# configure terminal
Regen (config)# boot system tftp filename ipaddress

Regen (config)# Ctrl-Z or exit
Regen# copy running-config startup-config
Building configuration ...
[OK]
Regen#

Note You must enter ROM monitor mode to use the following downloading options through the console port or the Ethernet port.

Entering ROM Monitor Mode

The following sections describe the commands used to enter ROM monitor mode automatically or manually. You can also increase the baud rate to increase the downloading process time.

Entering ROM Monitor Mode Automatically

You can configure Cisco IOS software to automatically enter the ROM monitor mode the next time the Cisco ONS 15104 boots by setting virtual configuration register bits 3, 2, 1, and 0 to zero. From the console port, enter the following configuration command starting in privileged EXEC mode:

Router# configure terminal

Router(config)# config-register 0x0

Router(config)# exit

Router# copy running-config start-config

Entering ROM Monitor Mode Manually

To enter ROM monitor mode:

Step 1 Enter the reload command in privileged EXEC mode to restart the Cisco ONS 15104.

Router# reload

Step 2 Press the <Break> key during the first 60 seconds while the system is booting to force the Cisco ONS 15104 to stop booting and enter the ROM monitor mode.

Step 3 To verify that you are in the ROM monitor mode, check that the prompt displayed on your screen is the ROM monitor mode prompt:

rommon # >

The # sign is the line number and increases incrementally at each prompt. The > sign is the prompt.

The new configuration register value, 0x0, becomes effective after you restart the
Cisco ONS 15104 with the reload command. The Cisco ONS 15104 remains in the ROM monitor mode and does not boot the operating system. As long as the configuration register value remains 0x0, you must manually boot the operating system from the console. See the previous section "Entering ROM Monitor Mode Automatically" to change the configuration register value.

ROM Monitor Commands

Enter the query command ? or help at the ROM monitor mode prompt to display a list of available commands. For example:

rommon 1 >  ?

alias       set and display aliases command
boot        boot up an external process
break       set/show/clear the breakpoint
confreg     configuration register utility
cont        continue executing a downloaded image
context     display the context of a loaded image
cookie      display contents of cookie PROM in hex
dev         list the device table
dir         list files in the file system
dis         display instruction stream
dnld        serial download a program module

sysret      print out info from last system return
tftpdnld    tftp image download
unalias     unset an alias
unset       unset a monitor variable
xmodem      x/ymodem image download
rommon 2 >

Note You can interrupt any command by pressing the <<Break>> key on the console.

Setting the Baud Rate

The console port default parameters are 9600 bps, 8 data bits, no parity, 2 stop bits. After the Ethernet port is configured, it only takes only 5 to 10 seconds to download the software using TFTP commands.

Table A-2 shows the downloading speed for the console port or the Ethernet port.

Table A-2: Download Speed according to the Baud Rate

Cisco ONS 15104 Interface	Baud Rate	Time Length
Console port	9600 bps	30 to 40 minutes
Console port	115200 bps	6 minutes
Ethernet port (configured)	9600 bps	5 to 10 seconds

Note Cisco recommends that you only use a console port speed of 115200 bps for downloading purposes because characters may be dropped by PC applications during normal console sessions at rates higher than 9600 bps. After downloading the software, be sure to reset the baud rate to
9600 bps.

To temporarily increase the baud rate to 115200 bps and thereby decrease the downloading time:

Step 1 Enter the confreg command in ROM monitor mode, as shown in the following example:

rommon 1 > confreg

Step 2 Download a Cisco IOS software image using one of the options described in this section.

Step 3 Reset the baud rate to the default parameters by entering the previously shown confreg command in Step 1.

Downloading Cisco IOS Software Images through the Ethernet Port

The following section describes how to download a Cisco IOS software image through the
Cisco ONS 15104's Ethernet port by:

Using tftpdnld Commands

Using the copy Command

Using tftpdnld Commands

You can download a Cisco IOS software image from a server that is accessible through the Ethernet port. Use the tftpdnld command to download the Cisco IOS software image into Flash memory.

To configure the Cisco ONS 15104 to download images:

Step 1 Connect one end of the Ethernet port cable to the device that provides Ethernet network connectivity in a router.

Step 2 Connect the opposite end of the Ethernet cable to the Ethernet port on the
Cisco ONS 15104.

Step 3 In ROM monitor mode, enter the tftpdnld command to download a Cisco IOS software image from a remote server accessible from the Ethernet network:

rommon # > tftpdnld flash <filename> (copies to flash)

rommon # > tftpdnld -r (copies to RAM)

where

r—Loads the Cisco IOS software image only to DRAM and launches the image without writing the image into Flash memory.

The tftpdnld command requires that you specify certain variables when you issue the command. The syntax for specifying a variable is:

VARIABLE_NAME=value

The variables that you must specify include the following:

IP_ADDRESS—IP address for the router you are using.
IP_SUBNET_MASK—Subnet mask for the router you are using.
DEFAULT_GATEWAY—Default gateway for the router you are using.
TFTP_SERVER—IP address of the server from which you want to download the image file.
TFTP_FILE—Name of the file that you want to download.

The following tftpdnld command variables are optional:

TFTP_VERBOSE—Print setting. The default is 1.

: 0=quiet—After you enter the tftpdnld command, the only information displayed until the command completes successfully or fails is the prompt

Do you wish to continue? y/n:

: 1=progress—Displays the state of the required tftpdnld command variables. Also displays progress characters to indicate successful and lost packet transmissions.
: 2=verbose—Displays all progress print setting messages, along with error information. The information provided by this print setting may be useful when debugging interface link and configuration problems that may prevent connecting to the TFTP server.

TFTP_RETRY_COUNT—Number of times from 1 to 65535 that the ROM monitor will retry ARP and ACK. The default is 7.
TFTP_TIMEOUT—Timeout of the download operation in seconds. The range is from 1 to 65535 seconds. The default is 7200 seconds.
TFTP_CHECKSUM—Performs a checksum test on the image. 0=checksum off, 1=checksum on. The default is 1.

After you specify the variables, you must reenter the tftpdnld command. For example:

rommon 1 > IP_ADDRESS=172.15.19.11

rommon 2 > IP_SUBNET_MASK=255.255.255.0

rommon 3 > DEFAULT_GATEWAY=172.16.19.1

rommon 4 > TFTP_SERVER=172.15.20.10

rommon 5 > TFTP_FILE=/tftpboot/regen-ih-mz

rommon 6 > tftpdnld

 
IP_ADDRESS=172.15.19.11
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=172.16.19.1
TFTP_SERVER=172.15.20.10
TFTP_FILE=/tftpboot/
 
Invoke this command for disaster recovery only.
WARNING: all existing data in all partitions on flash will be lost!
Do you wish to continue? y/n: [n]:

Enter y to begin downloading the Cisco IOS software image. When the process is complete, the ROM monitor mode prompt appears on your screen.

Using the copy Command

Note

In ROM monitor mode, enter the copy tftp flash command to download a Cisco IOS software image from a remote server accessible from an Ethernet network interface on a Cisco 12000 series router:

rommon 1 > copy tftp flash

rommon 2 >

: A menu prompts you to enter the filename.

Downloading Using FTP and RCP

You can also use File Transfer Protocol (FTP) or remote copy protocol (RCP) to download Cisco IOS software images to the Cisco ONS 15104. For details, see the section "Modifying, Downloading, and Maintaining Configuration Files in the document Configuration Fundamentals Configuration Guide for Cisco IOS Release 12.0.

Using FTP to Download Files

The Cisco ONS 15104 controllers support FTP server software that is used to transfer Cisco IOS software to the Cisco ONS 15104 controller. This software resides in the system controller until it is notified that data is ready to be transferred to the system controller. When notification occurs, the system controller downloads Cisco IOS software and communicates with the Cisco ONS 15104. The data is then transferred and stored on the Cisco ONS 15104 controller in a specified file.

Regen# configure terminal

Regen(config)# ftp-server enable 
Regen(config)# end

Regen# show running-config

Regen# copy running-config startup-config

Regen#

Enter the copy running-config startup-config command to save the current running configuration to the startup configuration file in NVRAM. For details, see the section, "Modifying, Downloading, and Maintaining Configuration Files in the document Configuration Fundamentals Configuration Guide for Cisco IOS Release 12.0.

Using RCP to Download Files

You can copy a file from a network server to the Cisco ONS 15104 or to another destination using rcp, use one of the following copy rcp EXEC commands. For example, the copy rcp running-config command replaces the configure network command in the command line. The copy rcp startup-config command replaces the configure overwrite-network command in the command line. For details, see the section, "Modifying, Downloading, and Maintaining Configuration Files in the document Configuration Fundamentals Configuration Guide for Cisco IOS Release 12.0.

Regen# configure terminal

Regen(config)# ip rcmd remote-username username

Regen(config)# copy system:running-config 
rcp:[[[//[username@]location]/directory]/filename
Regen(config)#

Enter the copy running-config startup-config command to save the current running configuration file to the startup configuration file in NVRAM.

Regen(config)# copy nvram:startup-config 
rcp:[[[//[username@]location]/directory]/filename
Regen(config)#

Downloading Cisco IOS Software Images through the Console Port

Cisco recommends using Xmodem commands only to download a Cisco IOS software image as a disaster recovery mechanism. In order to use Xmodem commands, you must be physically present at the Cisco ONS 15104 and connect a PC to the console port.

Caution Using Xmodem to copy a Cisco IOS software image will erase all Flash memory partitions.

Using Xmodem Commands

In ROM monitor mode, use the Xmodem commands to download a Cisco IOS software image through the console port.

Step 1 Use the Xmodem filename command to begin receiving a Cisco IOS software image through the console port, where the optional parameter filename specifies the name of the Cisco IOS software image that will be written to Flash memory:

rommon 1 > xmodem <image name> (copy to flash)

rommon 2 > xmodem -r <image name> (run from RAM)
rommon 3 >

After you enter the xmodem command, the following screen output displays:
