Features and Enhancements

Features and Enhancements in
DX NetOps Spectrum
10.4.1
casp1041
This release includes the following features and enhancements:
Secure Domain Connector (SDC) Enhancements
NCM Enablement in Secure Domain
DX NetOps Spectrum
now supports Network Configuration Manager (NCM) operations (for example, load/capture configurations) on the Secure Domain Connector (SDC)-managed models; that is, devices under a private network. From the current release, when you install SDC, NCM is automatically installed as a part of SDC; it is installed as a service.
For more information, see NCM Enablement in Secure Domain.
SDC Fault Isolation
Secure Domain Connector (SDC) is used for managing devices. When SDC gets down, all the devices managed by SDC become unreachable. In prior release, such devices would start generating individual alarms. Now, this behavior has changed in the current release. In this release, when SDC goes down, all devices modeled under SDC are suppressed and show the root cause as
SDC down
. Therefore, all related individual alarms are suppressed and users see only one alarm with the root cause as
SDC down
. It also helps users to efficiently manage devices and alarms.
For more information, SDC Fault Isolation.
SDC TrapX Improvements
This release now supports the SDC TrapX varbind filtering. This filtering supports the following operations that you can use with a combination of AND and OR statements:
  • Equals
  • NotEquals
  • StartsWith
  • EndsWith
  • Contains
  • NotContains
For more information, see the Varbind Filtering section in SDC TrapX Improvements.
DX NetOps Spectrum
Enhancements
SNMPv3 Support for Diffie-Hellman (DH)
This release of
DX NetOps Spectrum
now supports the creation of Diffie-Hellman (DH) profiles on SNMPv3. This ability provides a more robust and secure communication mechanism in
DX NetOps Spectrum
.
For more information, see the SNMPv3 Support for Diffie-Hellman (DH) section in Edit SNMP v3 Profiles Dialog.
SNMPv3 Community String Access Control
From the current release, you can control the access to the SNMPv3 community string information on models. You can decide whether you want to display or hide the SNMPv3 community string to specific users. This functionality, therefore, gives you the ability to restrict the display of this information, making it available only to those users who are supposed to view it.
For more information, see SNMPv3 Community String Access Control.
Enhanced WiFi Monitoring
From the current release, if any applicable alarm is raised on an access point (AP), then the alarm is asserted to that AP. Similarly, if an alarm is raised on a WLC controller, then the alarm is asserted to that WLC controller. This functionality helps in the proper organization of the alarms based on the associated AP or WLC controller, allowing you to manage your devices more efficiently. In prior release, all alarms were getting asserted to the WLC controller irrespective of the fact from where the alarm had been raised: AP or WLC controller.
For more information, see the Enhanced WiFi Monitoring section in WLC Manager.
Simplified Device Self Certification
In this release, you can import the uncertified devices and can certify them yourself instead of waiting for the next version of
DX NetOps Spectrum
to release a new list of certified devices.
For more information, see the Self-Certify the Unregistered Devices section in Uncertified Devices.
Support for Dynamic Alarm Tittle
Once you set the dynamic alarm title variable, you see more information about the alarm in the title. To use the functionality, you can create an event that has that varbind set to any value for example, by mapping a trap variable to a specific ID in an alert map file. You can also copy variable from other event using an event rule, and then map the event to an alarm using that ID as a discriminator.
For more information, see the Creating Dynamic Alarm Title section in Working with Events and Alarms.
Deployment Support for Kubernetes
Dockerized
DX NetOps Spectrum
components such as OneClick server, SpectroSERVER, SRM, and SDC can be deployed separately. It helps set up as distributed
DX NetOps Spectrum
deployment. Earlier, dockerization was supported only using Openshift. From the current release, dockerization is supported using Kubernetes to deploy distributed SpectroSERVER.
OneClick Enhancements
This release includes the following enhancements to OneClick:
Improve Spectrum REST API Capability (Swagger)
You can now access
DX NetOps Spectrum
API documentation using Swagger. The Swagger UI lets you visualize and interact with
DX NetOps Spectrum
REST APIs by providing visual documentation. The implementation is based on the Apache Swagger 2 feature. Click the
API Documentation
menu link in
DX NetOps Spectrum
OneClick Web interface to access the REST API.
For more information on using Swagger for REST API, see the
DX NetOps Spectrum
REST API Capability (Swagger)
.
SAML2 Authentication in
DX NetOps Spectrum
You can now authenticate users through your organization's Active Directory or intranet session.
DX NetOps Spectrum
now supports Security Assertion Markup Language (SAML) 2 authentication as a single sign-on login standard for this purpose. SAML is a standard for logging users into applications based on their sessions in another context.
For more information on how to use SAML 2 to authenticate your users, see SAML2 Authentication in
DX NetOps Spectrum
.
Export Topology View in SVG/Visio
You can now export the topology in XML and PNG formats. You can import the topology to third-party imaging applications (for example, draw.io) and change the topology as per your requirements. You can then export the updated topology to any supported output formats of that third-party imaging application.
For more information, see Export Topology View.
DX NetOps Spectrum
WebApp Improvements
This release includes the following enhancements to WebApp:
  • SSO Support is now provided.
  • Manual start is no longer required.
  • Logging out of WebApp redirects to the
    DX NetOps Spectrum
    administration page.
  • Handling WebApp to launch using any available port
    DX NetOps Spectrum
    now ensures that the OneClick WebApp port is updated to 9443 if it is available, or to any other available port.
  • Configure OneClick WebApp user session timeout
    When a user session is inactive for a specific duration, the session automatically logs out after the defined time. You can configure the user session timeout for WebApp users. By default, the session timeout option is disabled. You can enable the session timeout and set the duration after which the session must be timed out.
For more information, see OneClick WebApp (Beta).
Update Table or List Attribute Using a REST API
A new POST model is included in this release that lets you update the attribute of the specified model.
For more information, see model.
Add Bcc Field in Notification
From the current release, you can use the blind carbon copy (Bcc) option to send the alerts and notification even when the “To” and “Cc” fields are empty.
External Proxy Support for
DX NetOps Spectrum
-OI Integration
From 10.4.x,
DX NetOps Spectrum
to DX OI integration supports forward proxy. The proxy server details can be configured in Topology Store Configuration and SPectrum Data Publisher.
For more information, see Configuring the SpectrumDataPublisher section in Integrate with DX OI Connector Using
DX NetOps Spectrum
View the Client Details Web Page
From the current release, the Client Details table shows the client type in the WebApp column. In case the client is a WebApp, the Host Name and the Host Address columns show the respective client details. In prior release, the Host Name and the Host Address columns displayed the
localhost
details, when the client is a WebApp.
For more information, see View the Client Details Web Page.
Spectrum Performance View (Beta)
From the current release, Spectrum Performance View provides a real-time health dashboard for the distributed
DX NetOps Spectrum
environment. The administrator can run this tool to get the performance trends, it is disabled by default. SpectroSERVER tracks the performance statistics like Operating System Metrics (like CPU, memory, threads, and so on) and other internal metrics like total models, traps, events, alarms, and so on. These metrics are retrieved every minute and stored as an event on the SpectroSERVER Performance model.
DX NetOps Spectrum
Report Manager Improvements
This release includes the following enhancements to
DX NetOps Spectrum
Report Manager:
  • Set Report Manager preferences improvement
    Use the
    Jasper User Sync
    option to control the synchronization of
    DX NetOps Spectrum
    users with the Jasper server. The default value is True. Users are synchronized every hour during the event polling. During the synchronization,
    DX NetOps Spectrum
    Report Manager checks whether the user exists or not in Jasper.
    DX NetOps Spectrum
    Report Manager creates users with the default roles equivalent to
    DX NetOps Spectrum
    user roles. The default password is the same as the username. Once the user is created, the roles and password of the users are not modified or synchronized by
    DX NetOps Spectrum
    Report Manager. Users can now customize the roles and change the password.
  • Ability to customize the SRM reporting interval
    In the prior releases, SRM was collecting and sending inventory, alarms, events, services, and NCM data at 60 minutes of the interval from
    DX NetOps Spectrum
    and was publishing the report.
    From the current release, a new parameter
    instant_event_poller_processing_interval
    is added to let you customize the polling interval. The parameter lets the SRM process only the model create/destroy events and alarm events at five minutes of the interval. However, you can configure the polling interval. All other events are processed at 60 minutes of the interval. The configuration helps you get the updated inventory and alarms data in the report based on the configured interval rather than the regular 60 minutes time frame.
  • SRM purge process improvement
    The purge process for the event table is enhanced to use the truncate command instead of the delete command to expedite the purge process.
  • Partition Handler uses MySQL information schema to determine creation or deletion of partitions
    To streamline the partition life cycle,
    DX NetOps Spectrum
    now uses Partition Handler that uses MySQL information schema to determine creation/deletion of partitions.
  • Enhanced SRM Alarm Handler
    SRM now processes the synchronization of other landscapes even if one landscape is in the error state.
  • Enhanced RpmgrlnitializeLandscape.bat/sh script
    You can remove the stale buckets of any landscape using the
    ./RpmgrlnitializeLandscape.bat root -remStaleBuckets <landscape name>
    command.
For more information, see Set Report Manager Preferences.

DX NetOps Spectrum
-CA UIM Sync Status
In prior releases,
DX NetOps Spectrum
-CA UIM integration sync status was not getting updated for hosts and VMware in the OneClick view. Now, in the current release, the integration sync status is updating correctly under the
UIM Host Sync Configuration
section and
UIM Virtualization Sync Configuration
section (
Navigation
view,
UIM Manager, Information, Configuration
), as appropriate.
For more information, see the CA UIM-
DX NetOps Spectrum
Sync Status section in Integration with CA UIM.
Integration with ServiceNow - Support for ServiceNow New York Version
New scripts are added to support update adn close business rule actions for ServiceNow New York version.
For more information, see Update Script for New York Version and Clsoe Script for New York Version sections in Configuring OneClick Notifications for ServiceNow using MID Server.
Integration with Virtual Network Assurance (VNA)
This release includes the following enhancements to
DX NetOps Spectrum
- CA VNA integration:
  • Addition of the Meraki Dashboard API
    Virtual Network Assurance polls the Meraki Dashboard API. A new REST API is included in this release. The API returns mappings of
    DX NetOps Spectrum
    alarm model fields to the incident fields.
    For more information, see Support For Cisco Meraki.
  • Support for the new fault codes for Cisco ACI is now available.
  • Retaining the SNMP models on disabling the VNA integration
    All the SNMP models discovered through VNA are retained in
    DX NetOps Spectrum
    in their respective containers after VNA integration is disabled.
  • Roll-up condition being propagated up to the SDN hierarchy
    The roll-up condition is propagated to the parent models in the SDN hierarchy based on the composite condition value. The composite condition is calculated based on the alarms on the child models and configured threshold.
Integration with Service Desk
This release includes the following enhancement to
DX NetOps Spectrum
and Service Desk integration:
Map
DX NetOps Spectrum
Attributes to CA NIM Custom Attributes
In this release, you can create a ticket with five more
DX NetOps Spectrum
attributes (either alarm or model) in the ticketing system using the CA Normalized Integration Management (NIM) custom attributes. You can map
DX NetOps Spectrum
attributes to CA NIM custom attributes and populate the same in the ticketing system.
For more information, see the Customize
DX NetOps Spectrum
to CA NIM Field Mapping section in the Alarm Fields, REST examples and Attribute mapping page.
Deprecated ddm_load, ddm_save, and ddm_backup Binaries
In this release, ddm_load, ddm_save, and ddm_backup binaries have been deprecated. You can now use ddm_load.pl instead of ddm_load and ddm_save.pl instead of ddm_save and ddm_backup. The ddm_load.pl and ddm_save.pl (<SPECROOT>\SS\DDM) files leverage mysqlbackup.exe, which is more efficient for backup and restore. However, you must ensure that you have already converted your DDM database to InnoDB for the new utilities to work.
For more information, see the Support for Migrating DDM .mbi File (InnoDB), Migrate and Upgrade on Windows, and Migrate and Upgrade on Linux sections in Migrating and Upgrading.
