About this Publication

This guide provides instructions for Day-0 minimum configuration that is required to bring up Cisco NCS 1010 and associated devices into a functional state. Two approaches have been detailed:

The approaches do not address all of the possible network needs; instead, they provide models on which you can pattern your network. You can choose not to use features presented in the examples, or you can add or substitute features that better suit your needs.

Readers must be familiar with the operating system on which the NCS 1010 runs.

Overview of the NCS 1010 Optical Line System

Optical transport networks are evolving to address an exponential increase in network traffic faced by service providers. There is a growing need to support both digital coherent optics and high-performance transponders. This release introduces a new generation of Optical Line System (OLS), the Cisco Network Convergence Series 1010 (NCS 1010).

NCS 1010 OLS platform is an integral component of Routed Optical Networking solution. It provides point-to-point connectivity between routers with ZR/ZR+ optics and multiplexes signals from multiple routers over a single fiber. The OLS platform supports ROADM nodes of up to eight degrees using the NCS 1000 Breakout Patch Panel. NCS 1010 supports C-band WDM transmission in this release.

The NCS 1010 OLS platform provides:

  • Versatility by supporting multiple coherent sources such as:

    • 400 G digital coherent ZR/ZR+ optics (-10dBm output power)
    • High-performance DCO transponders such as NCS1K4-1.2T-K9 and NCS1K4-2-QDD-C-K9 cards that use high GBaud rates.

  • Simplicity by using integrated optical line cards that minimize fiber patching and cabling errors in the field.

  • Automation through IOS XR operating system that provides a rich suite of automation features including Zero Touch Provisioning (ZTP), open config YANG model support with NETCONF, and streaming telemetry.

  • Network monitoring through a combination of probes based on OTDR, OSC, OCM, and telemetry data.

The NCS 1010 OLS platform comprises of:

  • Network Convergence System (NCS 1010) chassis

  • Cisco NCS 1000 Breakout Patch Panel

  • Cisco NCS 1000 32-Channel Mux/Demux Patch Panels

Cisco NCS 1010

Cisco NCS 1010 is a 3 RU modular chassis that has an in-built External Interface Timing Unit (EITU) and multiple field-replaceable modules.

NCS 1010 supports different variants of the line card:

  • OLT-C Line Card: C-band Optical Line Terminal without Raman

  • OLT-R-C Line Card: C-band Optical Line Terminal with Raman

  • ILA-C Line Card: C-band In-Line Amplifier without Raman

  • ILA-R-C Line Card: C-band In-Line Amplifier with one side Raman

  • ILA-2R-C Line Card: C-band In-Line Amplifier with both sides Raman

For more information about the NCS 1010 chassis, see the data sheet.

Cisco NCS 1000 Breakout Patch Panel

It is a colorless breakout patch panel that enables you to implement long-haul topologies. These topologies use high TX power transponders such as the NCS1K4-1.2T-K9 or NCS1K4-2-QDD-C-K9 line card.

The patch panel supports up to 72 mux/demux channels and eight ROADM degrees using the following breakout modules:

  • NCS1K-BRK-8 (used as express interconnects)

  • NCS1K-BRK-24 (used to colorless topology)

For more information about the NCS 1000 breakout patch panel, see the data sheet.

Cisco NCS 1000 32-Channel Mux/Demux Patch Panels

These patch panels support colored channels that enable you to implement metro topologies. These topologies use low TX power modules such as 400G ZR/ZR+ coherent optics. These patch panels also support the Routed Optical Networking solution.

The two Mux/Demux patch panels (NCS1K-MD-32O-C and NCS1K-MD32E-C) support 32 channels and work as an add/drop unit for the OLT-C and OLT-R-C line cards.

For more information about data models and the supported YANG models, see Data Models Configuration Guide for Cisco NCS 1010.

Software Support

The following features are supported on Cisco NCS 1010:

Table 2. Feature Support

Feature

Description

Multiple boot options

After installing the hardware, boot the Cisco NCS 1010 system using the pre-installed operating system (OS) image. You can connect to the XR console port and power on the system.

Zero touch provisioning

Zero touch provisioning (ZTP) allows you to provision the network device with day 0 configurations and supports both management ports and data ports.

Disaster recovery

The Disaster Recovery feature allows the CPU replacement in the field without losing the configuration and software. The traffic is not affected.

Software and FPD upgrade

You can upgrade NCS 1010 by installing a new version of the Cisco IOS XR operating system on NCS 1010.

Datapath configuration

There are four types of controllers for Cisco NCS 1010. The controllers are the OTS, OTS-OCH, OSC, and DFB controllers. You can configure and view these controllers.

Optical channel monitoring

The Optical Channel Monitor (OCM) blocks in the OLT and ILA cards provide per-channel optical power monitoring.

Performance monitoring

You can configure and retrieve PM counters for the various controllers in flex-bin, 30-second, 15-minute, or 24-hour intervals. These parameters simplify troubleshooting operations and enhance data that can be collected directly from the equipment.

Connection verification

Connection verification checks the connection between the OLT-C line card and all the other passive modules to avoid miscabling during the node installation.

ASE loading

This feature allows to completely populate the transmission spectrum at LINE-TX independent of the actual system traffic load, thereby easing the system regulation starting from the installation.

Headless mode

Cisco NCS 1010 operates in headless mode for up to 72 hours, during process restarts, controller reload, LC warm reload, LC FPD upgrade, or removal of the controller (Online Insertion and Removal (OIR)). During this time, traffic is not impacted, although the control plane is not up and running.

Passive module support

There are two types of passive controllers for Cisco NCS 1010. The controllers are the OCH and OMS controllers. You can configure and view these controllers.

Remote node management

The remote node management feature in NCS 1010 allows you to remotely manage an ILA node that is not connected to a management network through an OLT gateway node over Optical Supervisory Channel (OSC) interface. The OLT node is connected to a management network and manages ILA node remotely.

Internode topology discovery

Optical applications on the NCS 1010 nodes must discover the OLT-OLT link topology. Span level applications must discover the adjacent nodes. Link level applications must learn the complete OLT-OLT link topology. NCS 1010 uses OSPF to discover the link topology and communicate topology information.

Span loss

The Span Loss calculation is an automatic calculation of span losses between NCS 1010 systems. The span loss verification algorithm calculates span loss by comparing power measurements at line Tx/Rx port at far end and line Rx/Tx port at near end.

Raman tuning

Raman Tuning Algorithm calculates and sets the different pump power values across 5 Raman pumps to obtain the target Raman Gain on a span.

Gain estimator

Gain Estimator analyses the span loss and sets the gain mode of the EDFA amplifier and provides the initial target gain for the amplifier.

Link tuner

Link tuner computes the target Power Spectral Densities (PSD) for APC by calculating the optimal PSDs for a span.

Automatic power control

Automatic Power Control (APC) corrects the power level differences and ensures that power for different channels is according to the target power profile for the spectrum. APC compensates for the degradation of the network over time. APC is enabled if automatic link bring up is enabled.

Automatic network turn up

You can bring up an NCS 1010 DWDM link without using any external tools. NCS 1010 measures optical parameters for all the spans at power-up. It then computes different setpoints for each of the spans to ensure optimal link performance for end-to-end traffic to pass through.

OTDR

An Optical Time Domain Reflectometer (OTDR) is an electronic-optical instrument that is used to characterize optical fibers. It checks defects and faults, and determines the amount of signal loss at any point in an optical fiber.

The OTDR application is a built-in functionality in ILA and OLT devices.

Multi-degree support

NCS1010 OLT devices support up to 8 degrees of ROADM express. You can set up multidegree connections using NCS1K-BRK-8 modules. Use BRK-8 modules for MPO breakout for express interconnect. For a multidegree topology, you must use as many BRK-8 modules and OLT devices as there are degrees. The BRK-8 modules help NCS 1010 nodes to achieve multidegree capability.

Network Topology

The sample network topology that is shown in this section has been used to explain the manual and ZTP bringup scenarios. It is a four degree topology that uses 13 NCS 1010 nodes. The BRK-8 modules are used to create express interconnects among SITE-2, SITE-3, SITE-4, and SITE-5 using MPO cables.

Bootup Process

After installing the hardware, boot the Cisco NCS 1010 system. You can connect to the XR console port and power on the system. NCS 1010 completes the boot process using the pre-installed operating system (OS) image. If no image is available, NCS 1010 can be booted using the iPXE boot or an external bootable USB drive.

Use any one of the tasks to boot the NCS 1010 chassis.

The boot process using iPXE has been illustrated in the following scenarios:

  • Manual Configuration Workflow: This workflow uses iPXE as the boot process followed by a manual bringup of the node.

  • ZTP Configuration Workflow: This workflow uses IPXE as the boot process followed by an automated bringup of the node using ZTP configuration files.

Preliminary Checks

After you successfully log into the console, you must perform some preliminary checks to verify the default setup. If any setup issue is detected, take corrective action before making further configurations.

The following samples are verification outputs of the default setup on OLT-R-C-SITE-4 node.

Similar verification steps can be performed on all the other NCS 1010 nodes.

When you boot up the NCS 1010 device for the first time, the ZTP process starts automatically and runs in the background. If the device is configured manually, the ZTP process continues to run in the background. If the ZTP process is not terminated gracefully, after an RP reload or power cycle, interfaces on the device can enter the shutdown state. To avoid this issue, it is suggested to disable the ZTP process gracefully. Use the following commands to disable the ZTP:

RP/0/RP0/CPU0:ios#ztp terminate
“ZTP Exited”
RP/0/RP0/CPU0:ios#ztp clean
RP/0/RP0/CPU0:ios#ztp disable

DHCP Configuration

DHCP configuration is required for both manual configuration and ZTP configuration.

To run iPXE and ZTP, you need a DHCP server. To configure a DHCP server, you must edit the dhcpd.conf file available at /etc/dhcp/. This configuration file stores the network information such as the path to the script, location of the ISO install file, location of the provisioning configuration (.cfg) file, and serial number or the MAC address of the chassis.

In the following example, the settings in the dhcpd.conf refers to the span connecting OLT-R-C-SITE-1 to OLT-C-SITE-2.

Figure 2. NetworkTopology Diagram
This is a sample topology diagram that is used to create the DHCP configuration file

Note


Restart the dhcpd service using the service dhcpd restart command every time you edit the dhcpd.conf file.


Add the following settings to the dhcpd.conf file :


Note


The ZTP configuration files (*.cfg) that are referenced in the dhcpd.conf file are detailed in ZTP Configuration Files Creation.

10.4.33.131 is the management IP address for the gateway node.

Manual Configuration Workflow

This section details how to manually bringup the nodes. Verification outputs have been added at various steps. The iPXE boot process via the BIOS interface has been used for this example.

The example used in this section is:

Figure 3. Network Topology Diagram
This is a network topology diagram used to illustrate the manual bringup of nodes.

Note


Before you use the iPXE boot, ensure that the DHCP server is set and is running. Create a dhcpd.conf file specific to the nodes in the network topology diagram. To see a sample dhcpd.conf file, see DHCP Configuration.


The boot process is initiated via the BIOS interface as follows:

  1. The node is reloaded or can undergo a power cycle.

  2. Press Esc to enter BIOS.

  3. Select the Save & Exit tab of BIOS.

  4. Choose UEFI: iPXE Network Boot.

Cross-connect Configuration

The OTS-OCH controllers are not created by default when the cards (NCS1K-ILA-2R-C, NCS1K-ILA-R-C , NCS1K-ILA-C, NCS1K-OLT-R-C , and NCS1K-OLT-C) are brought up. The LINE OTS-OCH controllers can be created using the hw-module command.

Optical Cross Connections can be configured only on OLT nodes. In these nodes, the OTS-OCH controller is not created automatically on the Add/Drop ports (COM side).The optical cross connect configuration defines the line side OTS-OCH channel as the source and creates an OTS-OCH controller on the ADD/Drop port to which the cross connection is made. The channel ID must be the same for both the LINE side and COM side OTS-OCH controller.

To illustrate the creation of the cross-connects, we are going to create a single channel from OLT-R-C-SITE-1 to OLT-C-SITE-8 in the topology diagram. The channel is mapped to 191.45 THz.

Bringup NCS 1010 Using ZTP

Perform the configurations in the following sequence to bring up NCS 1010 using ZTP.

DHCP Configuration

DHCP configuration is required for both manual configuration and ZTP configuration.

To run iPXE and ZTP, you need a DHCP server. To configure a DHCP server, you must edit the dhcpd.conf file available at /etc/dhcp/. This configuration file stores the network information such as the path to the script, location of the ISO install file, location of the provisioning configuration (.cfg) file, and serial number or the MAC address of the chassis.

In the following example, the settings in the dhcpd.conf refers to the span connecting OLT-R-C-SITE-1 to OLT-C-SITE-2.

Figure 4. NetworkTopology Diagram
This is a sample topology diagram that is used to create the DHCP configuration file

Note


Restart the dhcpd service using the service dhcpd restart command every time you edit the dhcpd.conf file.


Add the following settings to the dhcpd.conf file :


Note


The ZTP configuration files (*.cfg) that are referenced in the dhcpd.conf file are detailed in ZTP Configuration Files Creation.

10.4.33.131 is the management IP address for the gateway node.

ZTP Configuration Files Creation

You can build the ZTP configuration files based on your network requirements. The sample ZTP files created below are used to configure the nodes from OLT-R-C-SITE-1 to OLT-C-SITE-2 as shown in the figure below. You can create similar ZTP configuration files for the rest of the NCS 1010 nodes.

Figure 5. Network Topology Diagram
This is a sample topology diagram from OLT-R-C-SITE-1 to OLT-C-SITE2.

Note


You can remotely manage an ILA node that is not connected to a management network through an OLT gateway node via an OSC interface. ZTP can be initiated from a remote node through DHCP relay. For more information see, Remote Node Management in NCS 1010.


Build the ZTP configuration files by typing the following in Notepad and save them as .cfg files in the DHCP server.

ZTP Configuration Workflow

This section details how to bringup NCS 1010 nodes using ZTP. Verification outputs have been added at various steps. The iPXE CLI boot process has been used for this example.

The example used in this section is part of the overall network topology.

Figure 6. Network Topology Diagram
This is a sample topology that is used for explaining the ZTP configuration workflow.

Note


Before you use the iPXE boot, ensure that the DHCP server is set and is running. Create a dhcpd.conf file and the required ZTP configuration files specific to the nodes in the network topology diagram shown above. For samples of the dhcpd.conf file and the ZTP configuration files, see DHCP Configuration and ZTP Configuration Files Creation.


  1. Run the following CLI command to invoke the iPXE boot process to reimage the chassis:


    Note


    This command deletes the existing configuration on the node.

Cross-connect Configuration

The OTS-OCH controllers are not created by default when the cards (NCS1K-ILA-2R-C, NCS1K-ILA-R-C , NCS1K-ILA-C, NCS1K-OLT-R-C , and NCS1K-OLT-C) are brought up. The LINE OTS-OCH controllers can be created using the hw-module command.

Optical Cross Connections can be configured only on OLT nodes. In these nodes, the OTS-OCH controller is not created automatically on the Add/Drop ports (COM side).The optical cross connect configuration defines the line side OTS-OCH channel as the source and creates an OTS-OCH controller on the ADD/Drop port to which the cross connection is made. The channel ID must be the same for both the LINE side and COM side OTS-OCH controller.

To illustrate the creation of the cross-connects, we are going to create a single channel from OLT-R-C-SITE-1 to OLT-C-SITE-8 in the topology diagram. The channel is mapped to 191.45 THz.

Monitoring and Troubleshooting the Network

This section details processes that monitor and troubleshoot the network.

  • OTDR:The OTDR application is a built-in functionality in ILA and OLT devices. The OTDR measurement result is available in a SOR file format and it can be exported from NCS 1010 using SCP, TFTP, and SFTP format. The results can be used to find defects and faults, and determines the amount of signal loss at any point in an optical fiber.

  • Streaming Telemetry :Telemetry is an automated communications process that you use to collect measurements and other data at remote or inaccessible points and transmit to receiving equipment for monitoring. Model-driven telemetry(MDT) provides a mechanism to stream YANG-modeled data to a data collector. Model-driven telemetry allows network devices to continuously stream real-time configuration and operating state information to subscribers.

    Applications can subscribe to specific data items they need, by using standards-based YANG data models over gRPC Network Management Interface (gNMI) protocols. Devices publish structured data at a defined cadence, or on-change, based on the subscription criteria and data type.

    This telemetry data can be used for analysis and troubleshooting purposesto maintain the health of the network.

    This table lists the streaming telemetry sensor paths that are supported for NCS 1010.
