See the Cisco Network Insights – Advisor Application for DCNM User Guide for information and procedures on downloading and installing the NIA application.
The Cisco Network Insights - Advisor (NIA) application monitors a data center network and pinpoints issues that can be addressed to maintain availability and reduce surprise outages. NIA constantly scans the customer’s network and provides proactive advice with a focus on maintaining availability and alerting customers about potential issues that can impact uptime.
NIA consists of the following components:
· Advisories
o Software Upgrades
o Cisco Recommendations
· Cisco Notices
o EoL/EoS Dates
o Field Notices
· Issues
o Bug/PSIRT Reports
o Baseline Best Practices (Compliance)
· TAC Assist
o Log Collection
· Serviceability
o Schedule Driven (Compliance)
o On Demand
See the Cisco Network Insights – Advisor Application for DCNM User Guide for information and procedures on setting up the NIA application.
This section includes the following:
■ New and Changed Information for NIA
■ Compatibility Information for NIA
This section lists the new and changed features in this release and includes the following topics:
■ New Software Features in NIA
The following sections list the new software features in this release:
■ Notices
■ Bug Scan
NIA constantly checks Cisco Nexus Product Database for any outstanding EOL/EOS or Field Notices for Switches and analyzes them against the customer network to provide a list of customer devices affected by it.
Users can schedule or run an on-demand Bug-scan on their network. NIA collects tech supports from all the devices and run’s them against known set of signatures and flags the corresponding defects. NIA also generates an advisory for the customer. See Advisories for further details.
NIA scans customer configurations periodically and checks it against Cisco’s Hardening Guide. Such configurations are flagged as anomalies that customers can fix. Once fixed these anomalies are removed from the system.
The Technical Assistance Center (TAC) Assist feature helps customer collect information that they need for opening a Service Request (SR). Currently TAC Assist only captures the tech-support from the switches selected, puts them in a single folder and provides the location to the user.
NIA exposes 3 different type of Advisories in the first phase:
· Software-Advisory: Suggests the software version to upgrade, to fix the issues listed in the Advisory. This advisory gets generated when Bugs/PSIRTS are detected by the Bug Scan or when recommended software release changes.
· Hardware-Advisory: Suggests the hardware migration. This advisory gets generated in the event of EOL/EOS of the device.
· CallTAC-Advisory: Suggests to engage with Cisco TAC for resolving the issues listed in the Advisory. This advisory gets generated when NIA is not able to provide a specific advisory.
· FieldNotice-Advisory: Suggests the necessary action to be taken if a field notice is generated. In first version of NIA this is the same as field notice itself showing the affected devices.
The NIA generated Advisory suggests an upgrade image that best attempts to address bugs, PSIRTs, and software End of Life. In cases where a specific image is shown, the "Upgrade Impact" button runs the following check on listed devices:
ISSU check for non-disruptive upgrade to the suggested version (only NXOS Software version)
The results are displayed for each device with NONDISRUPTIVE/DISRUPTIVE/FAIL. Clicking on the status shows the output from the device. In case a conflict is noticed in image versions that can be suggested, a CALLTAC advisory action is shown, for example: the conflict could be due to different NXOS versions running on devices.
This section contains lists of open and resolved caveats.
This section lists the open caveats. Click the bug ID to access the Bug Search Tool and see additional information about the bug. If a caveat is fixed in a patch of this release, the "Fixed In" column of the tables specifies the release.
The following table lists the open caveats in this release.

Bug ID |
Description |
NIA App reports a Bug Scan or TAC Assist job partial failures, if tac-pac collection in-progress. A failure could occur if switch has a tac-pac collection running and NIA starts a Bug Scanner or TAC Assist job. |
|
NIA TAC Assist job only lists the folder name where the files are located for the job. |
This section lists the resolved caveats.
None in this release.
