This document provides information about Cisco Crosswork Network Controller 7.0, including product overview, solution components, new features and functionality, compatibility information, and known issues and limitations.

Overview

Cisco Crosswork Network Controller is a transport SDN controller that empowers customers to simplify and automate intent-based network service provisioning, health monitoring, and optimization in a multi-vendor network environment with a common GUI and API. Crosswork Network Controller simplifies operational workflows by consolidating both the service lifecycle and device management functions in a single integrated solution.

The solution offers intent-based network automation to deliver critical service orchestration and fulfillment capabilities, network optimization, path computation, service health monitoring, device deployment and management, and anomaly detection. Using telemetry gathering and automated responses, Cisco Crosswork Network Controller delivers network optimization capabilities that would be nearly impossible to replicate even with a highly skilled and dedicated staff operating the network.

The fully integrated solution combines core capabilities from multiple innovative, industry-leading products, including Cisco Network Services Orchestrator (NSO), Cisco Segment Routing Path Computation Element (SR-PCE), Crosswork Optimization Engine, and an evolving suite of applications operating on the Cisco Crosswork Infrastructure. Its unified user interface allows real-time visualization of the network topology and services and service and transport provisioning via a single pane of glass. Its feature-rich API allows operators to integrate the solution seamlessly with other applications they use to operate, monitor, and provision services on the network.

Primary Use Cases:

  • Orchestrated service provisioning: Provisioning of layer 2 VPN (L2VPN) and layer 3 VPN (L3VPN) services with underlay transport policies to define, meet, and maintain service objectives using the UI or APIs. Using Segment Routing Flexible Algorithm (Flex-Algo) provisioning and visualizing to customize and compute IGP shortest paths over a network according to specified constraints.

    For this use case, Cisco Crosswork Advantage must be installed.

  • Real-time network and bandwidth optimization: Intent-based closed-loop optimization, congestion mitigation, and dynamic bandwidth management based on Segment Routing and RSVP-TE. Optimization of bandwidth resource utilization by setting utilization thresholds on links and calculating tactical alternate paths when thresholds are exceeded.

  • Circuit Style Segment Routing Traffic Engineering (CS SR-TE) policy provisioning with network topology visualization:

    • Straightforward verification of CS SR-TE policy configurations

    • Visualization of CS SR-TE details, bi-directional active and candidate paths

    • Operational status details

    • Failover behavior monitoring for individual CS SR-TE policies

    • A percentage of bandwidth reservation for each link in the network

    • Manually triggered recalculations of existing CS SR-TE policy paths that may no longer be optimized due to network topology changes

    For this use case, Cisco Crosswork Advantage must be installed.

  • Local congestion management: Local Congestion Mitigation (LCM) provides localized mitigation recommendations within surrounding interfaces with the use of standard protocols. Data is gathered in real-time, and solutions are suggested when congestion is detected. LCM involves a “human-in-the-loop” approach, ensuring that the network operator has control over making changes. Additionally, LCM offers operators the choice to automate changes, enabling the system to implement changes to the network on its own. For this use case, Cisco Crosswork Advantage must be installed.

  • Visualization of network and service topology and inventory: The topology UI, along with the various tables that can be accessed from it, allows you to easily assess the health of the network and drill down to see details about devices, links, and services.

  • Performance-based closed-loop automation: Automated discovery and remediation of problems in the network by allowing Key Performance Indicator (KPI) customization and execution of pre-defined remediation tasks when a KPI threshold is breached. Health Insights and Change Automation functions must be installed for this use case.

  • Planning, scheduling, and automating network maintenance tasks: Scheduling an appropriate maintenance window for a maintenance task after evaluating the potential impact of the task (using Crosswork Planning Design). Automating the execution of maintenance tasks (such as throughput checks, software upgrades, and SMU installs) using playbooks. For this use case, Health Insights and Change Automation functions must be installed.

  • Secured zero-touch onboarding and provisioning of devices: Onboarding new IOS-XR devices and automatically provisioning Day0 configuration resulting in faster deployment of new hardware at lower operating costs. For this use case, Cisco Crosswork Essentials must be installed.

  • Visualization of native Segment Routing (SR) paths: Using the traceroute SR-MPLS multipath command to get the actual paths between the source and the destination can be achieved using Path Query. A traceroute command runs on the source device for the destination TE-Router ID and assists in retrieving the paths. For this use case, Cisco Crosswork Advantage must be installed.

  • Provision, visualize, and analyze tree segment identifier policies in multipath networks: Creating and visualizing static Tree-SID policies using the UI. Static mVPN Tree-SID policies, associated with existing or newly created L3VPN service models (SR MPLS point-to-multi-point), can be visualized and analyzed to manage and troubleshoot your multicast network efficiently. For this use case, Cisco Crosswork Advantage must be installed.

  • Transport slice provisioning: Cisco Crosswork Network Controller offers direct support for network slicing at the OSI transport layer. Using this solution, network engineering experts can design slices around customer intents and add them to a catalog. Network line operators can assign the profile identified for a given customer to their endpoints and adjust the constraints according to the customer's requirements. Once the slice is provisioned, the path chosen can be visualized. Customers wishing for even greater insight can use Service Health to gather additional performance data about the service. For this use case, Cisco Crosswork Advantage must be installed.

  • Interface Name—Displays the interfaceName value.

  • Interface Description—If applicable, displays any user specified text on the actual interface.

Table 6. Topology

Feature

What's New?

Enhanced topology visualization of large (more than 50 endpoints) VPNs

Enhanced navigation, provisioning, and visualization of the service overlay and details for large L3 VPNs containing up to 20,000 endpoints (UNI/PE-CE interface).

When a user selects a VPN service in the UI that is too large to display in full (since a maximum of 50 endpoints can only be displayed once), they can click Select endpoints and choose from a list of endpoints to visualize the service overlay and details. The list shows only the endpoints on devices in the current selected device group. The list also includes filters to narrow down the list of endpoints, making it easier to select.

Preconditions and limitations:

  • Visualization of large VPN support for L3VPN aligning with IETF L3 NM model.

  • Maximum number of vpn-node (PE) in the L3VPN: 4,000.

  • Maximum number of endpoints (UNI/PE-CE interface) in the L3VPN: 20,000.

  • Maximum number of policies or tunnels per large VPN: 5,000.

  • Maximum number of large VPN service instances in each deployment: 6.

  • Recommended provisioning of endpoints in a single request with a single L3VPN: 500.

Enhancements in the Topology UI - Links Visualization

A new Links tab displays all links on the map and a global links table in the Devices tab shows link details and metrics. Key metrics like bandwidth utilization, packet errors, packet drops, delay, and jitter are now shown in both the map and details panels, with delay and jitter available when Service Health is installed and SR-PM is enabled. You can also customize link color and metric thresholds in the Topology map and view historical data for collected metrics on the Link Details page.

Topology dashboard

A new Topology dashlet has been added to the Dashboards page, offering details on L2 and L3 links along with their associated metrics. When you click the L2 or L3 links in the dashboard, you will be directed to the Topology UI, where the corresponding map is displayed in the left pane. The Devices and Links tabs in the right pane offer detailed information about the devices and links on the map.

Table 7. Change Automation

Feature

What's New?

Support for check-sync action play

A new stock play, Perform Check Sync on the device, is available to achieve check-sync. You can use this Play prior to running other operations in the Playbook or as part of pre-maintenance. This Play checks the device sync status with NSO and performs a sync-from (pulling the present device config into NSO) only when needed, based on the Playbook's sync parameter value. It reduces the Playbook execution time and ensures the NSO configuration matches the device configuration.

  • If the Playbook's sync parameter is set to True and the device is not in sync, it will sync the device with the NSO configuration, and the operation succeeds with an in-sync status.

  • If the sync parameter is set to False and the device is not in sync, the Playbook fails with a commit message.

  • If the device is already in sync, the operation succeeds.

Table 8. Service Health

Feature

What's New?

Monitor Service Health using Cisco Provider Connectivity Assurance

Crosswork Network Controller can leverage external probes from Cisco Provider Connectivity Assurance (formerly Accedian Skylight) to provide additional insights into the health of the L3 VPN services in the network.

Note

 

Cisco Provider Connectivity Assurance integration is a limited-availability feature in this release. Contact your account team for more information. For more information, see the Monitor Service Health section in Cisco Crosswork Network Controller 7.0 Service Health Monitoring.

L3 VPN service monitoring enhancements

Service Health supports large-scale VPN visualization by monitoring L3VPN services at the node level and creating an Assurance graph for each service at either the node or endpoint level. If the graph contains more than 50 endpoints, Service Health indicates that the graph is too large to view and prompts you to use the Select Endpoints option to select and view up to 50 endpoints.

Enhanced metrics and insights with SR-PM

When Segment Routing Performance Measurement (SR-PM) is enabled on your devices, Service Health collects and processes additional metrics like Delay, Delay Variance, and Liveness to assess the performance of links and the health of TE policies. It also offers historical data and trends for these metrics, providing valuable insights into network performance and trends.

Service Health dashboard

A new Service Health Dashboard displays a consolidated view of L2 VPN and L3 VPN services. If an SLA for a service is breached, the UI clearly indicates the break, making detection of problems easier.

Table 9. Data Gateway

Feature

What's New?

Support for dual-stack configurations

Support for dual-stack configurations, enabling the system to establish connections using IPv4 and IPv6 protocols. This enables seamless, concurrent communication with various systems (such as NTP, DNS, and Syslog) and devices (SSH, SNMP, MDT) over IPv4 and IPv6. In dual-stack mode, IPv6 gets priority for all communication purposes.

For information on configuring a dual stack when creating or editing a pool and adding destinations, see the Cisco Crosswork Network Controller 7.0 Administration Guide.

New custom package to support different file formats

Important Notes

Take into consideration the following important information before starting to use Crosswork Network Controller 7.0:

  • Topology visualization:

    • Bandwidth utilization information is only available for physical interfaces and is not available for logical interfaces.



  • Crosswork Infrastructure:

    • It is recommended to deploy Crosswork Network Controller on a highly available cluster with shared storage.

    • Managed devices, VM host, VMs, and all integrated components should use the same NTP source to avoid time synchronization issues.

    • Confirm that the DNS and NTP servers are properly configured and reachable on the network the Crosswork Network Controller cluster will be using.

    • Cisco recommends using Terminal Access-Control System Plus (TACACS+), Lightweight Directory Access Protocol (LDAP) or Role-Based Access Control (RBAC) to track access and prevent unauthorized usage of Crosswork Network Controller capabilities.

    • During configuration, note the Crosswork Network Controller UI and CLI user names and passwords. Due to added security, the only way to recover the administrator password is to re-install the software.

    • In situations where it is expected to work with SR-PCE (for L3 topology discovery), we recommend the use of dual SR-PCEs in an HA configuration.

    • Use CSV files to quickly import and on-board device, credential, and provider information.

  • Obtaining geomaps for topology map renditions:

    To render geographical topology maps, if you do not have access to the map provider's website, you must download geo map files for the areas in the world you want displayed.

    Crosswork Network Controller allows you to obtain downloadable geographical maps (geomaps) based on their specific topology mapping needs. If your environment allows contact with the map provider website we specify in Crosswork, you do not need to download the map files. If your environment does not allow outside access, you will need to download the map files for the areas where your network requires coverage.

  • Service provisioning:

    The Cisco Network Services Orchestrator sample function packs are provided as a starting point for service provisioning functionality in Crosswork Network Controller. While the samples can be used “as is” in some limited network configurations, they are intended to demonstrate the extensible design of Crosswork Network Controller. Answers to common questions can be found here and Cisco Customer Experience representatives can answer general questions about the samples. Support for customization of the samples for your specific use cases can be arranged through your Cisco account team.


Note


For licensing and ordering information, work with your Cisco Partner or Cisco Sales representative to review the options described in the Cisco Crosswork Network Controller Ordering Guide.


Known Issues and Limitations

The table below shows known issues and limitations that should be taken into account before starting to work with Cisco Crosswork Network Controller 7.0.x.

Table 18. Infrastructure

Feature

Limitation

Fault and Alarm Synchronization

While geo redundancy enables a switch-over to an active cluster, it's important to take into account the timing of backups. Given the interval between the last backup and the restoration process, there is a loss of some alarm data from the devices. This is due to the time lag since the last backup was completed and restored.

Geo redundancy (with astack functionality)

If switchover is performed on a cluster on which Service Health is installed, the EOS data may contain partial metrics data (with intermittent gaps in the data metric sequence) for up to 24 hours.

Table 19. Traffic Engineering

Feature

Limitation

Transport Slice Provisioning

If the Monitoring Status for a Slice is enabled via API and the Slice is subsequently edited through the UI, the Monitoring Status is removed from the service and will need to be re-enabled if required.

TE Dashboard

Traffic Utilization is not supported on Tree-SID and SRv6 policies.

You cannot view the IGP path on the historical data when an event is selected.

The metric type for BWoD policies is not visible on the TE Dashboard.

Hop count metric and BWoD type are not shown in the TE Dashboard under metric/policy type.

State and Path change events are not visible in the Historic tab of a policy until you zoom in by 5 to 6 clicks.

IPv4 Unnumbered Interfaces

Bandwidth on Demand and SR Circuit Style Manager feature packs will not factor in IPv4 unnumbered interfaces.

Tree-SID policies are not supported.

RSVP-TE PCE-initiated tunnels are not supported.

Tree-SID

Only static Tree-SID policies can be created via the UI. Also, you can only update and delete static Tree-SID policies that have been created via the UI.

Tree-SID policies are only supported on devices running Cisco IOS XR software.

PCE HA is not supported if the static Tree-SID policy was configured manually on the device (not via the UI).

Tree-SID policies are not deleted from the UI when the SR-PCE in HA mode is down.

IPv4 Unnumbered interfaces are not supported.

Tree-SID policies are not supported in Label Switch Multicast (LSM) routing. In cases where LSM is enabled, IGP updates and traffic utilization data are not supported.

LCM will not operate in portions of the network carrying Tree-SID LSPs.

On Cisco 8000 Series Routers, only static Tree-SID policies with leaf role are supported.

Tree-SID policy details do not show IPv6 router ID or SRv6 core information.

SR-MPLS

In the SR-MPLS provisioning screen and while previewing an SR-MPLS policy with an IPv6 address, a parsing error is displayed instead of the correct error message: "Request Failed. Endpoint address is IPv6, IPv6 provisioning is not supported yet."

Updating the SID constraint on an existing policy is not allowed by the SR-PCE. The modification screen gives a successful update message, instead of a warning message that it is not allowed.

APIs

The Topology API cannot discover and report IPv6 Link-Local style links.

The Dashboard Export API cannot export CSV files to an external location. It can only export to /mnt/cw_glusterfs/bricks/rscoean/export.

BWoD

BWoD is disabled when the SR Policy Traffic field has 'Measured' selected and the Policy Violation field has 'Strict' selected.

Table 20. Service Health Monitoring

Feature

Limitation

Upgrade

  1. The Monitoring Status for existing services is displayed as Unknown by default.

  2. After the upgrade, some of the services (including the subservices device.health subservice and sr.policy.pcc.pm), may have the monitoring status as Monitoring Error. This is on account of some of the components being restarted (ASTACK, Crosswork Data Gateway tracker for example) during the upgrade.

    To clear the error, stop and start the monitoring again for the service to clear the active symptom. However, if the monitoring error is on account of an issue with device health, then stop monitoring for all the services related to the device and start monitoring the services again to clear the error.

  3. Metric data is restored and available only after the Crosswork Data Gateway becomes active following an upgrade. There is no metrics data available for the duration that the Crosswork Data Gateway was inactive.

    For example, if the Crosswork Data Gateway was active from October 10, 9:00 AM to October 10, 9:00 PM and was active again after an upgrade from October 11, 3:00 AM, an Event-of-Significance (EoS) generated on October 11 at 8:03 AM will lack metrics data between October 10, 9:00 PM and October 11, 3:00 AM.

Table 21. Service Provisioning

Feature

Limitation

Large VPN Service

If you are creating a large VPN service using the Crosswork Network Controller UI and the service creation times-out and becomes stuck in-progress, Cisco recommends you delete the large VPN service using the Crosswork Network Controller UI or the NSO CLI. If the large VPN service is deleted using the NSO CFS UI, it will still be visible in the Crosswork Network Controller UI.

Commit times for L3 VPNs with over 250 VPN nodes and 1,250 endpoints may take 10 minutes or more.

L2VPN service with RSVP-TE tunnel attached

With an L2VPN service, the RSVP-TE can be attached by either tunnel ID (te-tunnel-id) or tunnel service name (ietf-te-service).

If the RSVP-TE tunnel is attached by tunnel service name, when you navigate to VPN Services > Service details > Summary tab, the Resources section will display clickable links for additional RSVP-TE tunnel information.

If the RSVP-TE tunnel is attached by tunnel ID, when you navigate to VPN Services > Service details > Summary tab, the Resources section will remain empty and no clickable links with additional RSVP-TE tunnel information will appear.

VPN Service Provisioning

Service configuration data copied from Crosswork Network Controller VPN Services UI page cannot be used as a template for service provisioning from the Provisioning UI page. The Provisioning UI page has sample JSON/XML payload for each service type and should be used for service lifecycle management.

Table 22. Data Gateway

Feature

Limitation

Upgrade

When Crosswork Network Controller 6.0 is upgraded to 7.0, critical alarms remain uncleared, despite the data gateway VMs being UP and operational.

Table 23. Device Lifecycle Management

Feature

Limitation

Single VM Deployment

When you change the device's Admin State from UNMANAGED to DOWN, the system automatically sets the state to UP because the auto-attach process attaches the device to the embedded collectors and modifies its Admin State from DOWN to UP.

If changing the state to DOWN is necessary, you must manually change the state from the Edit Devices page as a next step.

For information on editing the device information, see the Edit Devices section in Cisco Crosswork Network Controller 7.0 Device Lifecycle Management.

Detailed Inventory

The detailed inventory view in topology:

  • Slot, bay, and container are not shown in the Tree View.

  • If a node has only one leaf child node, then that node is shown as a merged entity with the child. This is observed for pluggable ports.

  • Only the entities with the Serial Number (SN) are shown in Detailed Inventory Tree View. The entity without a SN is hidden, and its child is attached to the parent of the hidden entity.

Detailed inventory sync in topology view:

  • Optical ports for XR devices are merged with the corresponding SFP and the RSIP. The merging of ethernet ports for XR devices is currently not supported.

  • When clicking on the device node or the chassis node in the topology Tree View, both physical & logical interfaces can be viewed. If you clicking on other nodes, only the physical interfaces can be viewed.

Alarms and Events

When an event is created for the first time, the previous severity for the event is set to CLEARED because there is no historical data. For subsequent occurrences of the same event, the previous severity is updated based on the last recorded severity of that event. This allows the system to track changes in event severity over time.

In a cluster setup, you may encounter a call creation failure message for NATs, specifically for the gnmi/fault-iosxr-alarm-manager tagged alarm in IOS XR devices. This issue occurs when Kubernetes simultaneously creates multiple event processing instances. However, this error does not affect any other functionality.

Alarm Severity is not updated on repeated events.

When an alarm is created in response to an incoming event, it initially reflects the event's severity (e.g., Major). However, if subsequent events of the same type continue to arrive with the same severity, the alarm severity is not updated and may reflect a previous state such as 'Cleared.' This behavior is intentional and designed to avoid unnecessary alarm updates.
