Configuring the
Cisco ONS 15104

When you power up the Cisco ONS 15104 for the first time, it goes through a system bootstrap startup sequence and power-on self test (POST). After the POST, the Cisco IOS software is installed from Flash memory. If there are no problems, the green system ready LED goes on, and the
Cisco ONS 15104 automatically starts the setup command facility.

If fatal errors are detected during the POST, and the red system fail LED goes on, proceed to section "Cisco ONS 15104 Alarms and Alerts" in "Troubleshooting the Cisco ONS 15104."

If the system bootstrap startup sequence completes successfully, proceed with the configuration method that fits your network configuration and Cisco IOS software experience level.

If you are not familiar with Cisco IOS commands, the Cisco ONS 15104 will automatically enter the preconfigured defaults through the AutoInstall System Configuration Dialog when you answer a prompt. (See "Using AutoInstall".)

If you are familiar with Cisco IOS commands, you can answer a prompt that invokes the Configuration Mode Dialog and use the Cisco IOS commands to manually configure the
Cisco ONS 15104. (See "Using Set-Up Configuration Mode to Configure the Cisco ONS 15104".)

TimeSaver To verify network IP addresses before you begin to configure the Cisco ONS 15104, ask your system administrator or review the network plan.

TimeSaver To ensure that AutoInstall works properly, your system administrator must preconfigure the Transmission Control Protocol/Internet Protocol (TCP/IP) host on your network and put the required configuration files in the Cisco ONS 15104's nonvolatile random-access memory (NVRAM).

Booting the Cisco ONS 15104 for the First Time

This section describes how to boot the Cisco ONS 15104. When you boot the Cisco ONS 15104, the configuration files are loaded from NVRAM, and a valid Cisco IOS software image is usually loaded from Flash memory.

The preloaded system software consists of the following:

Running (current operating) configuration file
Startup configuration file
Valid Cisco IOS software image

The configuration register settings determine the source of the Cisco IOS software image (either Flash memory or a Trivial File Transfer Protocol [TFTP] server). The factory-default setting for the configuration register is 0x102, which indicates that the Cisco ONS 15104 first tries to load a Cisco IOS software image from Flash memory.

Note AutoInstall works only when the Cisco ONS 15104 is connected through the Ethernet port.

The following boot sequence occurs each time you power on the Cisco ONS 15104:

1. The Cisco ONS 15104 runs a POST to verify basic operation of the CPU, memory, and interfaces. When all of the configuration files finish loading, the system prompts you to start configuring the Cisco ONS 15104 using the AutoInstall configuration. (See the "Using AutoInstall" section.)

2. If a valid Cisco IOS software image is not found in Flash memory after five attempts to load, the Cisco ONS 15104 reverts to ROM monitor mode, so that you can install or upgrade a Cisco IOS software image. The system ready LED flashes when the Cisco ONS 15104 is in ROM monitor mode.

In ROM monitor mode, you can:

Use Xmodem commands to download a new Cisco IOS software image through the
Cisco ONS 15104's console port by using terminal emulation software. (See the section "Downloading Cisco IOS Software.")
Use the tftpdnld command to download a Cisco IOS software image through the Ethernet port. (See the section, "Downloading Cisco IOS Software.")
Use the file transfer protocol (ftp) command to copy a Cisco IOS software image from the router 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.)
Use the remote copy protocol (rcp) command to copy a Cisco IOS software image from the router 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.)

After a valid Cisco IOS software image is loaded, exit ROM monitor mode. The
Cisco ONS 15104 runs the System Configuration Dialog, so that you can configure the
Cisco ONS 15104's interfaces manually. (See the "Using Set-Up Configuration Mode to Configure the Cisco ONS 15104" section or the "Configuring Interfaces" section.)

3. After configuring the Cisco ONS 15104's interfaces for the first time, save the configuration to a file in NVRAM. (For details, see the "Saving Configuration Changes" section.)

Note For normal operation, there must be a valid Cisco IOS software image in Flash memory and a configuration file in NVRAM.

Configuring the Cisco ONS 15104 for the First Time

This section describes configuration options that include:

Using AutoInstall

AutoInstall starts when the Cisco ONS 15104 is connected to the Ethernet port. You can use AutoInstall to automatically configure the Cisco ONS 15104 after the power-on self test completes.

Note Autoinstall only works over the Ethernet port.

To start AutoInstall on the Cisco ONS 15104 do the following:

Step 1 Power on the Cisco ONS 15104 to load the Cisco IOS software image from Flash memory.

Step 2 When AutoInstall completes successfully, enter the copy running-config startup-config command in privileged EXEC mode to save the configuration settings to the
Cisco ONS 15104's NVRAM:

Regen# copy running-config startup-config

Regen#

Note If you do not enter the

copy running-config startup-config command, the configuration will be lost when you power off the Cisco ONS 15104.

Step 3 At the end of AutoInstall, press Return or enter no to accept the default answers and begin the System Configuration Dialog.

Verifying the Default System Configuration

During AutoInstall, the Ethernet interface and the SDCC0 and SDCC1 interfaces were assigned default IP addresses. If necessary, you can change the IP addresses on the interfaces to match the IP addresses on the your network. (See the "Configuring Cisco ONS 15104 Interfaces to Match the Network" section.)

To check the current configuration status, enter the show running configuration command in privileged EXEC mode:

Regen# show running configuration

Regen#

The following show running configuration command output example shows the default IP addresses that were assigned during AutoInstall:

Regen# show running-config

Configuring Cisco ONS 15104 Interfaces to Match the Network

You can isolate the Cisco ONS 15104's default interface configuration settings by entering the show ip interface brief command, in privileged EXEC mode:

Regen# show ip interface brief

Interface              IP-Address      OK? Method Status                Protocol
Ethernet0              10.1.0.2        YES NVRAM  up                    up      
SDCC0                  11.1.0.2        YES NVRAM  up                    up

Regen#

To change the Cisco ONS 15104's default interface configuration settings to match the IP addresses on the existing network, enter the global configuration mode to specify each interface. In interface configuration mode, change each interface IP address, as shown in the following example:

Regen# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.
Regen(config)# interface ethernet0

Regen(config-if)# ip address 20.1.0.1 255.255.255.0

Regen(config-if)# interface sdcc0

Regen(config-if)# ip address 22.1.0.1 255.255.0.0

Regen(config-if)# interface sdcc1

Regen(config-if)# ip address 33.1.0.1 255.255.0.0

Regen(config-if)# exit

Regen(config)# exit

 
Regen#

To verify that the interface configuration settings match the IP addresses on the existing network, enter the show ip interface brief command in privileged EXEC mode. Note that the output shows that the interface configuration settings were modified manually.

Regen# show ip interface brief

Interface              IP-Address      OK? Method Status               Protocol

For details on configuring each type of interface, see the following section, "Configuring Interfaces."

Configuring Interfaces

If you want to change the IP address of the Cisco ONS 15104's interface to match other IP addresses and the subnet mask that is used on the network, see the following sections to configure each interface:

Verifying Cisco ONS 15104 Interface Status

You can use the show controller ? command in privileged EXEC mode to list commands that will show the status of the Cisco ONS 15104's interfaces:

Regen# show controller ?

 
SDCC      Show SDCC parameters
ethernet  Show ethernet controllers
regen     show regen controller state
|         Output modifiers
Regen#

Configuring the Ethernet Interface

You can configure the Ethernet interface to connect to a local-area network (LAN). The
Cisco ONS 15104 supports only one LAN interface connection. To configure the Ethernet interface parameters, you need to know the IP address and subnet mask.

In the following configuration output example, the Ethernet0 interface was configured with a default IP address and subnet mask during AutoInstall, as follows:

interface Ethernet0
 ip address 10.1.0.2 255.255.0.0
 no ip directed-broadcast
 no keepalive
!

Follow these steps if you want to change the default IP address that was configured during AutoInstall, and assign a new IP address to the Ethernet interface:

Step 1 Enter the configure terminal command to enter the configuration mode:

Regen# configure terminal

Regen(config)#

Step 2 Enter the interface name:

Regen(config)# interface ethernet0

Regen(config-if)#

Step 3 Enter the ip address and subnet mask

Regen(config-if)# ip address 20.15.5.9 255.255.255.0

Regen(config-if)# exit

Regen(config)# exit

Regen#

Step 4 Verify the new Ethernet IP address by entering either of the following commands:

Regen# show running-config

Regen#

Regen# show interface Ethernet0

Regen#

Step 5 To save the configuration changes to NVRAM, enter the copy running-config startup-config command.

Regen# copy running-config startup-config

Regen#

Configuring the Section Data Communication Channel (SDCC) Interfaces

The Cisco ONS 15104 supports LAN interface connections through two OC-48 regeneration ports that contain two SDCC interfaces, SDCC0 and SDCC1. Figure 5-1 shows the Cisco ONS 15104 connected to OC-48 line card ports. The SDCC interfaces must be configured with sequential IP addresses, which means that the router IP addresses must follow in sequential numbers, for example, 10, 11, 12, and so on. You may have to reconfigure the SDCC interfaces to achieve this. Follow the steps in this section to verify the prerequisites and configure both the SDCC interfaces.

Figure 5-1: Connecting Cisco ONS 15104 to OC-48 Line Cards

SDCC Interface Prerequisites

One of the following must be true for SDCC interfaces to work properly:

1. All SDCC interfaces that are on the same subnet, for example, 11.11.11.x and IP routing must be enabled.

2. All SDCC interfaces can be on different subnets. IP routing and Routing Information Protocol (RIP) must be enabled on each Cisco ONS 15104.

: For example, when two routers that are on two different subnets are connected to the
Cisco ONS 15104, you must enable RIP on each subnet.

Enabling RIP and Configuring the SDCC0 Interface

The configuration tasks in this section explain how to enable RIP on two subnets through the
Cisco ONS 15104 and configure the SDCC0 interface. The IP address for SDCC must overlap the networks configured for the RIP protocol.

To enable RIP on the Cisco ONS 15104 on two subnets, enter the following commands:

Regen# configure terminal
Regen(config)# router rip
Regen(config)# network 10.0.0.0 (subnet 1)
Regen(config)# network 11.0.0.0 (subnet 2) 
Regen(config)# exit
Regen#

Note The labels (subnet 1) and (subnet 2) are for reference clarification and not part of the command that you enter.

Configuring the SDCC0 Interface

Follow these steps to configure the SDCC0 interface:

Step 1 Enter the configure terminal command to enter the configuration mode:

Regen# configure terminal

Regen(config)#

Step 2 Enter the interface name:

Regen(config)# interface SDCC0

Regen(config-if)#

Step 3 To configure the SDCC0 interface, enter the IP address and subnet mask:

Regen(config-if)# ip address 10.a.b.c 255.255.255.0

Step 4 Enter exit to return to global configuration mode, then privileged EXEC mode:

Regen(config-if)# exit

Regen(config)# exit

Regen#

Step 5 After you assign an IP address, add the following commands to the SDCC0 interface to keep the interfaces up and prevent data traffic shutdowns:

Regen# configure terminal

Regen(config)# interface SDCC0

Regen(config-if)# ip address 10.a.b.c 255.255.255.0

Regen(config-if)# keepalive

Regen(config-if)# no shut

Regen(config-if)# exit

Regen(config)# exit

Regen#

Step 6 Verify the new IP address for the SDCC0 interface by entering the show interface command:

Regen# show interface SDCC0

 
interface SDCC0
bandwidth 192
ip address 10.a.b.c 255.255.255.0
ip directed-broadcast
keepalive
crc 32
!

Configuring the SDCC1 Interface

To configure the SDCC1 interface:

Step 1 Enter the configure terminal command to enter the configuration mode:

Regen# configure terminal

Regen(config)#

Step 2 Enter the interface name:

Regen(config)# interface SDCC1

Regen(config-if)#

Step 3 To configure the SDCC1 interface, enter the IP address and subnet mask:

Regen(config-if)# ip address 11.x.y.z 255.255.255.0

Regen(config-if)#

Step 4 Enter the exit command to return to privileged EXEC mode.

Regen(config-if)# exit

Regen(config)# exit

Regen#

Step 5 After you assign an IP address, add the following commands to the SDCC1 interface to keep the interfaces up and prevent data traffic shutdowns:

Regen# configure terminal

Regen(config)# interface SDCC1

Regen(config-if)# ip address 11.x.y.z 255.255.255.0

Regen(config-if)# keepalive

Regen(config-if)# no shut

Regen(config-if)# exit

Regen(config)# exit

Regen#

Step 6 Verify the new IP address for the SDCC1 interface by entering the show interface command:

Regen# show interface SDCC1

 
interface SDCC1
bandwidth 192
ip address 11.x.y.z 255.255.255.0
ip directed-broadcast
keepalive
crc 32

Configuring the Regen Controller Module Interfaces

This section explains how to configure the two Cisco ONS 15104 controller module interfaces, Regen 0 and Regen 1, that monitor the SONET section overhead on incoming data.

Note The configuration of the Cisco ONS 15104 controllers in their default state is usually adequate. The special configurations shown below are only for advanced users in special networks (Add Drop Multiplexer (ADM) connections and/or Synchronous Digital Hierarchy (SDH) networks).

The OC-48 regeneration ports provide access to the Cisco ONS 15104 controller module interfaces, Regen 0 and Regen 1. When you connect the Cisco ONS 15104 to an OC-48 controller through the OC-48 fiber connectors, the Regen controller module interfaces are automatically up. After you configure the two Cisco ONS 15104 controller module interfaces, you can send configuration commands that will monitor and operate the SONET section overhead on incoming data.

Step 1 To verify the status of the Regen 0 controller, enter the show controller regen 0 command in privileged EXEC mode.

Table 5-1 explains the output from the show controller regen command.

Table 5-1: Description of show controller command Output

Output Field	Description
Regen0 is up	Regenerator 0 interface is administratively up.
Error Count	Error Count on regenerator 0 interface.
RxClockFail	Receive clock failed error.
SLOS	Loss of signal. There must be a clear, unobstructed path between the transmitters and receivers. Loss of sync. Indicates that an optical module has lost clock synchronization.
SLOF	Loss of frame. Indicates a SONET or SDH framing error.
BIP(B1)	Bit Interleaved Parity. Bit errors in the payload can then be detected and reported as maintenance information.
Active Defects:	Indicates which types of errors have active defects.
Active Alarms:	Indicates which types of alarms are active.
Alarm reporting enabled for:	Indicates which type of alarm reports you selected.
B1 TCA threshold:	B1 BER threshold crossing alarm. Reports B1 bit error rate (BER) threshold crossing alarm errors
Framer 0, addr=0x68004000:	Describes the framer setting and the contents of the packet overhead.

Step 3 Enter the configure controller command to access the controller configuration commands:

Regen# configure controller

Regen(config-controller)#

Step 4 In controller configuration mode, enter the query command ? to determine which Regen controller configuration commands are active:

Regen(config-controller)# ?

 
Controller configuration commands:
default      Set a command to its defaults
description  Controller specific description
exit         Exit from controller configuration mode
help         Description of the interactive help system
no           Negate a command or set its defaults
regen        Modify regen controller parameters

Step 5 Enter the regen ? command to determine which Regen controller configuration subcommands are active:

Regen(config-controller)# regen ?

ais-shut       Send LAIS when shutdown
b1-threshold   Set BER threshold for B1 TCA alarm
framing        Specify framing format
j0             Specify Section Trace byte value
loopback       Set 4402 as facility-loopback
report         Enable reporting of selected alarms
sdcc-passthru  Set section dcc channel passthru
shutdown       Shut down the REGEN controller

Step 6 Enter the regen overhead ? query command to determine which options are active.

Regen(config-controller)# regen overhead ?

j0  0x01 for compatibility, 0xCC is default

Step 7 Enter the regen overhead j0? command to determine the range of the values for j0.

Regen(config-controller)# regen overhead j0 ?

<0-255>  byte value

Step 8 Enter the regen flag j0 ? command to find valid values to configure the section trace:

Regen(config-controller)# regen flag j0 ?

<0-255>  0x1 for compatibility, 0xCC is default

Step 9 Enter the regen framing command to provision the framer format. The default is sonet.

Regen(config-controller)# regen framing sonet

Regen(config-controller)#

Note

Step 10 Enter the regen report ? query command to enable the Cisco ONS 15104's alarms:

Regen(config-controller)# regen report ?

b1-tca      B1 BER threshold crossing alarm
j0-mismatch Section Trace Mismatch
rxclk-fail  Receive Clock failed
slof        Section Loss of Frame
slos        Section Loss of Signal

Enter the [no] regen report command to disable the Cisco ONS 15104's alarms

Step 11 Enter the regen threshold b1-tca ? query command to determine the values of the
Cisco ONS 15104's B1-threshold (for B1 TCA):

Regen(config-controller)# regen threshold b1-tca ?

  <3-9>  Bit error rate (10 to the minus n)
Regen(config-controller)#

Enter the [no] regen threshold command to disable the Cisco ONS 15104's alarms

Saving Configuration Changes

Any time you change the Cisco ONS 15104 configuration, you must save the changes to NVRAM or to a disk, or they will be lost if there is a system reload or power outage. This section describes how to save configuration changes.

There are two types of configuration files:

Running (current operating) configuration, which is stored in random-access memory (RAM).

Startup configuration, which is stored in NVRAM or Flash memory.

To display the current running configuration:

Step 1 Enter enable to enter privileged EXEC mode,

Step 2 Enter the show running-config command.

Step 3 Enter the copy running-config startup-config command to save the current running configuration to the startup configuration file in NVRAM.

Regen> enable

Regen# show running-config

Regen# copy running-config startup-config

Regen#

To display the startup configuration:

Step 1 The Cisco ONS 15104 always starts in user EXEC mode, so you must enter enable to enter privileged EXEC mode.

Step 2 Enter the show startup-config command.

Step 3 Enter the copy startup-config running-config command to write the startup configuration to the running configuration:

Regen> enable

Regen# show startup-config

Regen# copy startup-config running-config

Regen#

To erase both configuration files and start over:

Step 1 Enter enable to enter privileged EXEC mode.

Step 2 Enter the write erase and reload commands:

Regen> enable

Regen# write e

rase

Regen# reload

Regen#

Caution This command sequence will erase the entire configuration in NVRAM.

The following is an example of the system response to the write erase commands:

Regen# write erase

Erasing the nvram filesystem will remove all files! Continue? [confirm]
[OK]
Erase of nvram: complete
