This chapter describes how to configure the Cisco Optical Regenerator and includes the following sections:
The following sections provide minimum software configuration information. Detailed software configuration information is available in the Cisco IOS Software Configuration Guide and command reference publications. You can use the same command line interface-based network management system for Cisco 12000 series routers and the regenerator to track network statistics and resources. See the section "If You Need More Information" in the preface "About This Guide" for information.
When you power up the regenerator 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 regenerator automatically starts the setup command facility.
If fatal errors are detected during the POST, and you see the red system fail LED, proceed to the "Cisco Optical Regenerator Alarms and Alerts" in "Troubleshooting the Regenerator."
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 regenerator 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 regenerator. See "Using Set-Up Configuration Mode to Configure the Regenerator".
 | TimeSaver
Ask your system administrator or review the network plan to verify network IP addresses before you begin to configure the Cisco Optical Regenerator. |
| 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 regenerator's nonvolatile random-access memory (NVRAM). |
This section describes how to boot the Cisco Optical Regenerator. When you boot the regenerator, 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:
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 Optical Regenerator first tries to load a Cisco IOS software image from Flash memory.
The following boot sequence occurs each time you power on the regenerator:
1. The regenerator 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 regenerator 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 regenerator reverts to ROM monitor mode, so that you can install or upgrade a Cisco IOS software image. The system ready LED flashes when the regenerator is in ROM monitor mode.
In ROM monitor mode, you can:
Once a valid Cisco IOS software image is loaded, exit ROM monitor mode. The regenerator runs the System Configuration Dialog, so that you can configure the regenerator's interfaces manually. See the "Using Set-Up Configuration Mode to Configure the Regenerator" section or the "Configuring Interfaces" section.
3. After configuring the regenerator's interfaces for the first time, save the configuration to a file in NVRAM. See the "Saving Configuration Changes" section for details.
This section describes configuration options that include:
AutoInstall starts when the regenerator is connected to the Ethernet port. You can use AutoInstall to automatically configure the Cisco Optical Regenerator after the power-on self test completes.
To start AutoInstall on the Cisco Optical Regenerator:
Step 1 Power on the Cisco Optical Regenerator 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 regenerator's NVRAM:
Regen# copy running-config startup-config Regen#
Step 3 At the end of AutoInstall, press Return or enter no to accept the default answers and begin the System Configuration Dialog.
First, would you like to see the current interface summary? [yes]: no Any interface listed with OK? value "NO" does not have a valid configuration 00:00:03:%SYS-5-CONFIG_I:Configured from memory by console 00:00:03:%SYS-5-RESTART:System restarted -- Cisco Internetwork Operating System Software IOS (tm) REGEN48 Software (REGEN48-I4-M) 12.0(19991208:213216) Copyright (c) 1986-1999 by cisco Systems, Inc.

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 "Configuring Regenerator 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 Building configuration... Current configuration: ! version 12.0 no service pad service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Regen ! logging buffered 4096 debugging ! ip subnet-zero ! ! controller REGEN 0 ! controller REGEN 1 ! ! interface Ethernet0 ip address 10.1.0.2 255.255.0.0 no ip directed-broadcast no keepalive ! interface SDCC0 ip address 11.1.0.2 255.255.0.0 no ip directed-broadcast bandwidth 192 crc 32 ! interface SDCC1 ip address 12.1.0.2 255.255.0.0 no ip directed-broadcast bandwidth 192 Regen#
(Remainder of displayed text committed from example.)
You can isolate the regenerator'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 SDCC1 12.1.0.2 YES NVRAM up up Regen#
To change the regenerator'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 Ethernet0 20.1.0.1 YES manual up up SDCC0 22.1.0.1 YES manual up up SDCC1 33.1.0.1 YES manual up up Regen#
You can manually configure the Cisco Optical Regenerator by using Set-Up Configuration Mode. The regenerator will invoke Set-Up Configuration Mode when it is connected to the network through either the Ethernet port or the OC-48 regenerator ports.
To enter Set-Up Configuration Mode, you must boot the regenerator without any default configuration settings, by following these procedures:
Step 1 Power ON the regenerator. The regenerator runs the same system bootstrap startup sequence that was previously shown in the section "Booting the Cisco Optical Regenerator for the First Time."
Step 2 At the prompt to enter the initial System Configuration Dialog, enter yes to go into Configuration mode:
Would you like to enter the initial dialog? [yes]: yes 00:00:03:%SYS-5-CONFIG_I:Configured from memory by console 00:00:03:%SYS-5-RESTART:System restarted -- Cisco Internetwork Operating System Software IOS (tm) REGEN48 Software (REGEN48-I4-M) 12.0(19991208:213216) Copyright (c) 1986-1999 by cisco Systems, Inc.

(Remainder of displayed text omitted from example.)
The previous show running configuration command output verifies that an IP address is assigned to the Ethernet interface, but no IP addresses are assigned to the SDCC0 and SDCC1 interfaces.
The following examples show how to assign an IP address to the SDCC0 and SDCC1 interfaces that will match the IP addresses on your network:
Regen# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Regen(config)# interface sdcc0 Regen(config-if)# ip address 22.1.0.1 255.255.255.0 Regen(config-if)# no keepalive Regen(config-if)# no shutdown 00:17:18: %LINK-3-UPDOWN: Interface SDCC0, changed state to up 00:17:19: %LINEPROTO-5-UPDOWN: Line protocol on Interface SDCC0, changed state to up Regen(config-if)# exit Regen(config)# Regen(config)# interface sdcc1 Regen(config-if)# ip add 33.1.0.1 255.255.255.0 Regen(config-if)# no keepalive Regen(config-if)# no shutdown Regen(config-if)# 00:17:44: %LINK-3-UPDOWN: Interface SDCC1, changed state to up 00:17:45: %LINEPROTO-5-UPDOWN: Line protocol on Interface SDCC1, changed state to up Regen(config-if)# Regen(config-if)# controller regen 0 Regen(config-controller)# no regen loopback Regen(config-controller)# exit Regen(config-if)# exit Regen(config)# exit Regen#
For details on configuring each type of interface, see the following section, "Configuring Interfaces."
If you want to change the IP address of the regenerator'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:
You can use the show controller ? command in privileged EXEC mode to list commands that will show the status of the regenerator's interfaces:
Regen# show controller ? SDCC Show SDCC parameters ethernet Show ethernet controllers regen show regen controller state | Output modifiers Regen#
You can configure the Ethernet interface to connect to a local-area network (LAN). The Cisco Optical Regenerator 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#
or
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#
The Cisco Optical Regenerator supports LAN interface connections through two OC-48 regeneration ports that contain two SDCC interfaces, SDCC0 and SDCC1. Figure 5-1 shows the Cisco Optical Regenerator 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.
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 regenerator.
For example, when two routers that are on two different subnets are connected to the regenerator, you must enable RIP on each subnet.
The configuration tasks in this section explain how to enable RIP on two subnets through the regenerator and configure the SDCC0 interface. The IP address for SDCC must overlap the networks configured for the RIP protocol.
To enable RIP on the regenerator 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#
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 !
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 ! Regen#
This section explains how to configure the two regenerator controller module interfaces, Regen 0 and Regen 1, that monitor the SONET section overhead on incoming data.
The OC-48 regeneration ports provide access to the regenerator controller module interfaces, Regen 0 and Regen 1. When you connect the Cisco Optical Regenerator to an OC-48 controller through the OC-48 fiber connectors, the Regen controller module interfaces are automatically up. Once you configure the two regenerator 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.
Regen> enable Regen# show controller regen 0 Regen0 is up Error Count: RxClockFail = 0 SLOS = 1 SLOF = 1 BIP(B1) = 0 Active Defects: LOS LOF Active Alarms: SLOS Alarm reporting enabled for: RxClockFail SLOS SLOF B1-TCA B1 TCA threshold: B1 = 10e-6 Framer 0, addr=0x68004000: general_cntrl=0x0, active_led=0x1 ,gpio_port_mode=0x0, gpio_port_data=0x0, gpio_port_cntrl=0xF ,mask_3=0x0, mask_2=0xFF, mask_1=0xFF ,diag=0x0 , rsp_cntrl_1=0x10, ttog_cntrl=0x0 ,ttog_ovrhd_src_1=0x8C , Link Status=0xE0, LED control=0x80 ,regen_cntrl=0xA0 , Regen#
Step 2 To verify the status of the Regen 1 controller enter the show controller regen 1 command:
Regen> enable Regen# show controller regen 1 Regen1 is up Error Count: RxClockFail = 0 SLOS = 1 SLOF = 1 BIP(B1) = 0 Active Defects: LOS LOF Active Alarms: SLOS Alarm reporting enabled for: RxClockFail SLOS SLOF B1-TCA B1 TCA threshold: B1 = 10e-6 Framer 1, addr=0x68001000: general_cntrl=0x0, active_led=0x1 ,gpio_port_mode=0x0 , gpio_port_data=0x0, gpio_port_cntrl=0xF ,mask_3=0x0 , mask_2=0xFF, mask_1=0xFF ,diag=0x0 , rsp_cntrl_1=0x10, ttog_cntrl=0x0 ,ttog_ovrhd_src_1=0x8C , Link Status=0xE0, LED control=0x80 ,regen_cntrl=0xA0 , Regen#
Table 5-1 explains the output from the show controller regen command.
| Output Field | Explanation |
|---|---|
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. |
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 have 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)#
Step 10 Enter the regen report ? query command to enable the regenerator'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 regenerator's alarms
Step 11 Enter the regen threshold b1-tca ? query command to determine the values of the regenerator'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 regenerator's alarms
Any time you change the Cisco Optical Regenerator 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:
To display the current running configuration:
Step 1 Type 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 Because the regenerator always starts in user EXEC mode, type 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#
Step 1 Type enable to enter privileged EXEC mode.
Step 2 Enter the write erase and reload commands:
Regen> enable Regen# write erase 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
