Conformance Report

Conformance Report

Conformance report enables you to visualize and understand the lifecycle of your hardware and software in the network. This assists you in planning upgrades and hardware refresh. Conformance Report is generated everyday for each fabric for hardware and software conformance and weekly for each fabric for scale conformance. In the report you can view the conformance status of software, hardware, combination of both software and hardware, and scale conformance status for fabrics.

You can use Conformance Report to view current and project the future status of software and hardware inventory in your network against known EoS and EoL notices to ensure conformance. You can also monitor scale conformance status for onboarded fabrics.

Using Conformance Report you can,

  • Minimize risk of running End-of-Sale (EoS) or End-of-Life (EoL) switches.

  • View current status of software and hardware inventory in your network against known EoS and EoL notices to ensure conformance.

  • Project the future outlook of software and hardware inventory in your network.

  • Monitor scale conformance status for onboarded fabrics.

Conformance Report displays the summary of conformance status for software, hardware, and scale for selected fabrics.

In the Conformance report, for hardware and software conformance switches are classified into 3 severities based on the software release or hardware platform EoL dates and end of PSIRT dates. The severities include:

  • Critical: End of PSIRT date or Last Date of Support occurs in the past.

  • Warning: EoL date for software release or EoS for hardware release occurs in the past.

  • Healthy: End of PSIRT date, or Last Date of Support and EoL date or software release or EoS for hardware release occurs in the future, or EoL for software release or EoS for hardware release is not announced.

The End of SW Maintenance Releases Date in the End-of-Sale and End-of-Life Announcement and the end of PSIRT date is used as reference milestone to classify the inventory into a category of Critical, Warning, or Healthy.

In the Conformance report, the scale conformance status for fabrics is based on Cisco’s Verified Scalability Guidelines for the software version running in switches and controllers when applicable. The severities include:

  • Conformant: All metric values are under 90%.

  • Approaching limits: One or more metric values are between 90% and 100%.

  • Violated Limits: One or more metric values are over 100%.

Connectivity Analysis

Connectivity Analysis

Connectivity Analysis allows you to analyze flows between two different endpoints, provide insight into how your endpoints are connected, and helps you spot where problems might be occurring.

Connectivity Analysis detects and isolates offending nodes in the network for a given flow and includes the following functionalities:

  • Traces all possible forwarding paths for a given flow across source to destination endpoints.

  • Identifies the offending device with issue, resulting in the flow drop.

  • Helps troubleshoot to narrow down the root cause of the issue, including running forwarding path checks, software and hardware states programming inconsistencies through consistency-checks, and further details related to packets walkthrough.

Connectivity Analysis Options

  • Embedded Logic Analyzer Module (ELAM) - ELAM is a diagnostic tool that helps troubleshoot ethernet traffic flows. It captures the packet from an active flow and analyzes the ethernet frames for packet drops. ELAM requires an active flow between the source and destination hosts. You can enable this option to analyze an available active flow.

  • Operations, Administration, and Maintenance (OAM) - OAM is a protocol for monitoring and troubleshooting ethernet networks. You can enable this option to locate potential drops for active hosts or to track details such as reachability and probable route of the flow in a VXLAN EVPN based fabric topology, without the need of active traffic between the hosts. OAM is supported only on VXLAN fabrics.

  • Consistency Checker - Consistency Checker ensures system consistency and aids in root cause analysis and fault isolation by verifying the alignment between software and hardware tables. These checks are performed within each switch between data plane and control plane for all the networking entities related to the chosen endpoint conversation. You can enable this option to detect control plane and data plane configuration and operational inconsistencies along the flow between specified endpoints or routes.

Layer 2 ToR Support

With Layer 2 ToR support, Connectivity Analysis offers the following capabilities:

  • Incorporate the device into the topology of a connectivity analysis job.

  • Provide detailed node-level flow information, including ingress interfaces and egress paths.

  • Initiate ELAM (Embedded Logic Analyzer Module) and capture packet details on ToR switches.

  • Conduct consistency-check validations on ToR switches.

Supported topologies

  • ToR switch with port channel directly connected to leaf switch.

  • ToR switch connected to leaf switches in a vPC pair.

  • ToR switches with port channels connected to leaf switches individually. The leaf switches are in a vPC pair.

  • ToR switches in vPC with leaf switches along with ToR switches connected to hosts in a vPC pair.

Guidelines and Limitations

  • You can submit up to 10 jobs per fabric.

  • At any point of time, you can run only 1 Connectivity Analysis job per fabric. You can stop a job in the queue and run another job.

  • Connectivity Analysis is supported on Cisco NX-OS release 9.3(7a) and later.

  • Connectivity Analysis job is not triggered if all onboraded devices are shown as incompatible.

  • You must upgrade to the latest available RPM. Upgrading the RPM has no impact on traffic forwarding or on the switch and switch reload is not required. The View Nodes banner displays the number of nodes that are compatible and up to date. Click Update to upgrade. After the upgrade is completed, in the Node page, click Refresh to view the status.

    ndi-ca-update-nodes-ndfc.jpg

  • OAM is only supported on VXLAN fabrics.

  • OAM is only supported between VTEPS and as a result the OAM path will be displayed between Layer 3 networks.

  • You can run Connectivity Analysis only on online fabrics.

Additional Guidelines for NDFC Fabrics in Monitor Mode

  • NDFC has two fabric types (Classic LAN and External Connectivity Network) which support the Fabric Monitor Mode. Fabric Monitor Mode disables the ability to make any changes to the corresponding fabric.

  • Connectivity Analysis depends on switch-side RPMs to function. These RPMs typically ship installed on the switches, but when updates become available, they must be deployed from Nexus Dashboard Insights.

  • If a fabric has Fabric Monitor Mode enabled, Nexus Dashboard Insights cannot push the RPM updates as required.

    ndi-ca-enable-monitor-mode-ndfc.jpg
    note.svg

    Attempting to install RPM updates from Nexus Dashboard Insights to NDFC switches with Fabric Monitor Mode enabled will result in a failed task.

  • If Connectivity Analysis shows an RPM update available for the switches, you will need to first disable the Fabric Monitor Mode for the respective fabric from NDFC, then perform the RPM update from Connectivity Analysis on Nexus Dashboard Insights.

ndi-ca-viewing-compatibility-ndfc.jpg

  • Once the update is completed, you can re-enable Fabric Monitor Mode on NDFC to use Connectivity Analysis with the switches.

Filtering Information

In some cases, you might be able to filter results to find information more easily.

For example, you might have a situation where there a large number of endpoints under a single leaf switch, but you are only interested in endpoints that have a certain VLAN value.

You could filter the information to show only those specific endpoints in this situation.

Use the following operators for the filter refinement:

Operator Description

==

With the initial filter type, this operator, and a subsequent value, returns an exact match.

!=

With the initial filter type, this operator, and a subsequent value, returns all that do not have the same value.

contains

With the initial filter type, this operator, and a subsequent value, returns all that contain the value.

!contains

With the initial filter type, this operator, and a subsequent value, returns all that do not contain the value.

<

With the initial filter type, this operator, and a subsequent value, returns a match less than the value.

< =

With the initial filter type, this operator, and a subsequent value, returns a match less than or equal to the value.

>

With the initial filter type, this operator, and a subsequent value, returns a match greater than the value.

> =

With the initial filter type, this operator, and a subsequent value, returns a match greater than or equal to the value.

Log Collector

Log Collector

The Log Collector feature enables you to collect and upload the logs for the devices in your network to Cisco Intersight Cloud. It also enables Cisco TAC to trigger on-demand collection of logs for devices on the fabric and pulls the logs from Cisco Intersight Cloud.

The Log Collector has two modes:

  • User initiated - The user collects the logs for devices on the fabric and then uploads the collected logs to Cisco Intersight Cloud after the log collection job is completed. You can automatically upload the log files to Cisco Intersight Cloud after the log collection job is completed.

  • TAC initiated - Cisco TAC triggers on-demand collection of logs for specified devices and pulls the logs from Cisco Intersight Cloud.

Device Connectivity Notifier for TAC Initiated Collector

Nexus Dashboard Insights uses the device connectivity issue notifier on Cisco Nexus Dashboard to communicate with the devices. The notifier checks for TAC triggered on-demand collection of logs. In case the fabric is not configured properly to communicate with the device, Nexus Dashboard Insights notifies the following:

  • The device is not configured for node interaction.

  • You can not run a Log Collector job on the device.

  • Nexus Dashboard Insights cannot connect to the device.

If the node interaction is not healthy on the device, you cannot choose the device for Log Collector to collect logs. In the GUI, the device is greyed out.

Uploading logs to Cisco Intersight Cloud

  • Ensure that Nexus Dashboard Insights is connected to Cisco Intersight Cloud.

  • Ensure that Nexus Dashboard Insights is connected to Cisco Intersight Device Connector.

Choose Analyze > Analysis Hub > Log Collector > Create Log Collector Job.

Traffic Analytics

Traffic Analytics

Traffic Analytics enables you to monitor your network’s latency, congestion, and drops.

Traffic Analytics automatically discovers services running in your network by matching well-known Layer 4 ports to their corresponding service endpoint categories. Nexus Dashboard Insights then assesses service performance based on thresholds for the following metrics:

  • Latency: Measures the overall time in microseconds it takes a packet to go from one place to another.

  • Congestion: Measures network bandwidth utilization and quality of service (QoS) activation mechanisms to determine if a service is experiencing network congestion.

  • Drops: Measures the score or number of dropped packets versus transmitted packets considering factors such as CRC errors, faulty cables, and other devices.

An anomaly is raised if there is any deviation in the performance metrics such as latency, congestion, and drops. The performance score is calculated for each conversation and aggregated to the service endpoint or endpoint level to raise anomalies.

The performance score is calculated based on the following:

  • Congestion - Consistent congestion avoidance active between endpoints is calculated.

  • Latency - Deviation from the average latency of the previous conversations is calculated.

  • Drops - Directly correspond to an issue with the conversation or service.

Using Traffic Analytics you can:

  • Monitor traffic pervasively.

  • Report performance issues using anomalies raised for performance metrics.

  • Sort top talking services and clients and determine the top talkers in the system.

  • Determine the SYN or RST counts per service.

  • Troubleshoot conversations or flows on-demand.

Traffic Analytics conversations

A TCP conversation is a 4-tuple including source IP address, destination IP address, destination port, and protocol. A non-TCP conversation is a 3-tuple including source IP address, destination IP address, and protocol. In case a single client establishes multiple communication flows initiated by multiple source ports towards a service endpoint, all related statistics would be aggregated as a single entry in the Traffic Analytics table. A service endpoint is defined by an IP address, a port, and a protocol.

An anomaly is raised after the conversation rate limit is exceeded. Navigate to Admin > System Settings > Flow Collection. In the Traffic Analytics status for the last hour area, you can view if the conversation rate approaches or exceeds the limits. You can also view if there are any Traffic Analytics record drops.

Sustainability Report

Sustainability Report

The Cisco Nexus Dashboard Insights sustainability report helps you monitor, predict, and improve your network’s energy usage, its related carbon emissions, and its total energy cost. The sustainability report enables you to get insights on energy utilization, CO2 emissions, and energy cost for all your fabrics on a monthly basis.

The report is generated by calculating the monthly values for Power Consumption and by summing the usage data across all of your devices at each of your fabrics for every single day in the chosen month. This data is then combined with the Cisco Energy Manager to provide greater insight into what that usage means in terms of energy cost, estimated emissions, and estimated switch power consumption. For more information about the Cisco Energy Manager, see Cisco Energy Manager.

The summary area of the report contains information such as estimated cost, estimated switch power consumption, sources of emission, and estimated emissions.

  • Estimated Cost gives you insight into any expected increase or decrease in your fabrics' energy bills based on your monthly energy use.

  • Estimated Switch Power Consumption gives you insight into how efficiently your switches are using electricity. Estimated PDU Power Consumption gives you insight into how much electricity your devices or Panduit power distribution units (PDUs) are using.

  • Estimated Emissions gives you insight into the sustainability your fabrics have on your total CO2 emissions, based on the sources and amount of energy used.

If you have Panduit PDUs onboarded to Nexus Dashboard, you can use the Data Source toggle to see two different electricity values on the sustainability report: one for switches only, and one for PDUs.

  • Switch Data: Uses only the electricity data reported by individual switches added to a fabric.

  • PDU Data: Uses the electricity data reported by a supported PDU, which could include switches, fans, and any other devices physically plugged into the PDU.

Depending on which value you choose in the Data Source toggle, the values calculated for your other metrics, including estimated cost and emissions, will vary.

Using the sustainability report, you can:

  • Better anticipate increases in your fabrics' energy bills so that your budgets more accurately reflect real-world usage.

  • Better follow the hourly energy usage of an individual fabric. By spreading out usage to avoid peak hours surcharges, you may be able to lower your electricity bill over time.

  • See the direct sustainability impact running your fabric has on climate change. Following your emissions over time also gives you the ability to choose lower-carbon sources and track your progress toward meeting ESG goals.

Delta Analysis

Delta Analysis

Nexus Dashboard Insights performs analysis of sites at regular intervals and the data is collected at an interval depending on the number of nodes.

Number of nodes Interval

Fewer than 100

2 hours

100 to 400

3 hours

Greater than 400

12 hours

At each interval, Nexus Dashboard Insights captures a snapshot of the controller policies and the fabric run time state, performs analysis, and generates anomalies. The anomalies generated describe the health of the network at that snapshot.

Delta analysis enables you to analyze the difference in the policy, run time state, and the health of the network between two snapshots.

Create Delta Analysis enables you to create a new delta analysis and manage existing analysis. See Create Delta Analysis.

Health Delta

Health Delta analyses the difference in the health of the fabric across the two snapshots.

See View Health Delta Analysis for more details.

Policy Delta for NDFC

Policy Delta for NDFC fabrics analyzes the changed nodes or switches across two snapshots and obtains a co-related view of what has changed in the NX-OS switches.

See View Policy Delta Analysis for more details.

Guidelines and Limitations for Delta Analysis

  • The Delta Analysis functionality currently supports the local authentication domain only.

  • While you are currently allowed to create more than one Delta Analyses at any given time, we recommend that you do not queue more than one Delta Analysis at any given time. In addition, we recommend that you wait for some time (approximately 10 minutes) between creating new analyses to avoid the risk of adversely impacting the run time of the concurrent online fabric analysis.

    The interdependency arises because the Delta Analysis results in an increased load on the database. Sustained high-database load from multiple back-to-back Delta Analyses may affect the run-time of the online analysis.

  • When you choose a switch in the Changed Nodes area, in Policy Delta, the difference in the configuration between the two snapshots is displayed.

  • For Policy Delta, Audit Logs is not currently supported.

Create Delta Analysis

Choose Analyze > Analysis Hub > Delta Analysis > Create Delta Analysis.

  1. In the Delta Analysis Name field, enter the name. The name must be unique across all the analyses.

  2. Click Fabric to choose the fabric.

  3. Click Choose Earlier Snapshot and choose the first snapshot for the delta analysis. Click Apply.

  4. Click Choose Later Snapshot and choose the second snapshot for the delta analysis. Click Apply.

    note.svg

    The two snapshots chosen for the delta analysis must belong to the same fabric.

  5. View the Summary of the Delta Analysis created in Summary.

  6. Click Save. The status of the delta analysis is displayed in the Delta Analysis table. Post completion, you can View Delta Analysis or Create another Delta Analysis.

The delta analysis dashboard displays general information along with health and policy delta.

View Health Delta Analysis

Health Delta analyses the difference in the health of the fabric across the two snapshots. The results are displayed in the following areas:

The toggle for 'Include Acknowledged Anomalies' allows you to filter out the acknowledged anomalies from the results displayed if enabled. If it is disabled, manually acknowledged anomalies are included in the Anomaly Count.

  • Anomaly Count: Displays the difference in anomaly count per severity across the snapshots.

The first count represents the anomalies found only in the earlier snapshot. The second count represents the anomalies found only in the later snapshot.

Delta analysis now performs an object delta rather than a count delta. So along with the count, you can now view how many anomalies were cleared, how many are unchanged and how many are new anomalies.

The anomaly count also displays the difference for the different types of anomalies. It is displayed for Critical, Major and Warning.

  • Delta by Resources: Displays the count of resources by type that are new, lost or unchanged. You can also specifically view the resources who’s count has changed by clicking the View Changed Only toggle. The filter bar allows you to filter the data by resource. The gear icon allows you to customize the columns as per your view. The table also shows the count delta and the health delta. Count delta includes both healthy and unhealthy resources. Healthy resources will not have any anomalies associated with it if filtered. Health delta shows only unhealthy resources and will return anomalies if filtered by anomalies.

The analysis is available for the following resources :

  • Interfaces

  • Endpoints

  • Spines

  • Border Gateways

  • Leafs

  • Border Leafs

  • VLANs

  • VRFs

  • SVIs

Bug Scan

Collecting information on bugs that might affect your network using Bug Scan

Nexus Dashboard Insights collects technical support information from all the devices and runs them against known set of signatures, and flags the corresponding defects and PSIRTs. Nexus Dashboard Insights also generates advisories for PSIRTs and anomalies for defects. See Anomalies and Advisories to learn more about Metadata support.

The Bug Scan feature collects technical support logs from devices in a fabric and scans them for bugs that could have been hit. If the CPU and memory usage is below the set threshold of 65% then the tech support logs are collected and the Bug Scan is carried out for the devices. If the CPU and memory usage is above the set threshold, the devices are excluded from the Bug Scan and eventually will be reconsidered for the next default Bug Scan or when you run an on-demand Bug Scan for that device.

If the node interaction is not healthy on the device, you cannot choose the device for Bug Scan to collect logs. The device cannot be selected to configure a job.

You can also run an on-demand Bug Scan for a fabric. For more information, see the On-Demand Analysis section in Getting Started.

Default Bug Scan

Bug Scan is run for all the fabrics onboarded to Nexus Dashboard Insights and is auto-scheduled every 7 to 14 days for each device, depending on the number of nodes and fabrics on the Nexus Dashboard cluster. This schedule is fixed and is not customizable.

Bug Scan is run on devices contained in a fabric either based on the last Bug Scan or the onboarding time if a Bug Scan has not been run before. Priority is given to devices with a longer time elapsed since the last Bug Scan. After a Bug Scan is run on a device, regardless of whether it succeeds or fails, another Bug Scan will not be run for the same device for the next 7 days.

Bug Scan is auto-scheduled to run on devices only if the CPU and memory metrics for the devices are streamed and the percentage usage is less than 65%.

However, on-demand Bug Scan is an exception and is prioritized over any auto-scheduled runs and does not consider the CPU and memory metrics as it is user-initiated. If auto-scheduled Bug Scan is in progress and on-demand Bug Scan is initiated, based on the available resources in the Nexus Dashboard nodes the on-demand Bug Scan will start while the current Bug Scan is in progress or after the current Bug Scan is completed.

Only one Bug Scan at the time can run on a specific device. However, if you have one set of devices where Bug Scan is already in progress, a second (auto-scheduled or on-demand) Bug Scan can run only if Nexus Dashboard Insights has enough resources available. Otherwise it will be put on hold and started as soon as resources are available.

View Active and Susceptible Bugs

The Bug Scan feature collects technical support logs from devices in a fabric and scans them for bugs that could have been hit. You can view the active and susceptible bugs affecting your network after the Bug Scan is completed.

  • Active Bugs - Bugs present in the software version that are detected in your network based on its configuration and tech support files. The signatures are developed with a confidence level. The confidence level indicates the percentage of confidence the signature has in detecting that bug accurately. Active bugs are chosen only when the confidence level of a signature is over 75%.

  • Susceptible Bugs - Bugs present in the software version that may potentially impact your network.
