Configuring Intelligent O&M

Context

iMaster NCE-CampusInsight (CampusInsight for short) is an intelligent network analysis platform that collects and analyzes various issues such as connectivity and performance issues on campus networks, helping users quickly detect wireless network issues, deeply analyze issues, and efficiently rectify faults. CampusInsight can implement intelligent O&M centering on user experience.

• Visualized user experience management: Based on the standard Streaming Telemetry technology, network data is dynamically collected within seconds. The experience of each user and application at each moment is visible.
• Fault identification and proactive prediction: CampusInsight uses big data and AI technologies to automatically identify connectivity issues (slow association, association failure, slow authentication, authentication timeout, and authentication failure), air interface performance issues (weak signal coverage, high interference, and high channel utilization), roaming issues (repeated roaming, roaming failure, disconnection), device issues (unexpected AP disconnection, high CPU or memory usage, and PoE power supply failure), and application issues. Leveraging machine learning, CampusInsight dynamically generates baselines based on historical data. By comparing and analyzing the baselines with real-time data, CampusInsight can proactively predict possible faults and identify, handle, and prevent the faults in advance.
• Fault demarcation and root cause analysis: CampusInsight intelligently identifies fault patterns and impact scopes based on the network O&M expert system and various intelligent algorithms, helping administrators identify and demarcate faults. CampusInsight can also analyze possible fault causes by working with the big data platform and provide rectification suggestions.

Configuration Description

For details about how to configure CampusInsight when it is deployed independently, see the iMaster NCE-CampusInsight Product Documentation (Independent Deployment). This section describes how to configure network interconnection between CampusInsight and iMaster NCE-Campus in the integrated deployment scenario. After the interconnection configuration is complete, log in to CampusInsight directly or switch to the CampusInsight web UI from iMaster NCE-Campus to perform service and O&M operations. For details, see the iMaster NCE-CampusInsight Product Documentation (CloudCampus).

Configuration Roadmap

1. Configure interconnection with iMaster NCE-Campus on CampusInsight.
2. In the system administrator portal of iMaster NCE-Campus, configure the interconnection with CampusInsight.
3. In the tenant administrator portal of iMaster NCE-Campus, configure data synchronization to CampusInsight.
4. In the tenant administrator portal of iMaster NCE-Campus, enable the function of reporting data for devices.
   • To enable APs working in Fit mode to report data, log in to the WAC's web system and configure the corresponding function.
   • To enable devices to report DHCP log information and information about the interfaces that users access, configure DHCP snooping and ARP snooping, respectively.

Configuration Tasks

Configuring DHCP Snooping and ARP Snooping

1. Choose Provision > Physical Network > Site Configuration, and select Interface from the Switch drop-down list in the upper left corner.

2. Click the Physical Interface tab. Select a downlink interface (user access interface) on the target device, and access the Advance page. Then, enable DHCP Snooping and

   ARP Snooping.

3. Select an uplink interface of the target device, access the Advance page, and set DHCP Snooping to Trusted.

Enabling the Function of Reporting Data to CampusInsight

The time on devices must be the same as that on CampusInsight. If the time difference between the devices and CampusInsight is greater than 10 minutes, CampusInsight cannot display the data reported by the devices. You are advised to configure an NTP server with the same source to ensure time consistency between devices and CampusInsight.

• Enable the function of reporting data to CampusInsight for switches.
  1. Choose Monitoring > Health > Device 360. On the Device 360 page, click Service Experience Analysis under Switch in the upper left corner. Click Add. In the Select Device area, select a device whose audio and video performance data is to be collected. In the Service Experience Analysis Config area, enable the eMDI function, set Monitored service type to Audio+Video, and set Monitoring period. Then click Apply.

  2. Choose Monitor > Monitor Settings > Monitor Settings. On the Monitor Settings page, set the protocol type to HTTP protocol-2. On the Global Configuration tab page of CloudInsight, enable the functions of reporting performance data, terminal monitoring information, and device logs. Then click OK.

• Enable the function of reporting data to CampusInsight for Fit APs.
  1. Choose Design > Site Agile Deployment > Device Management. On the Device Management page, click the Cloud-based Device tab, and then click the WAC name to access the web system of the WAC (switch with the native WAC function in this example). Click Configure Device in the upper right corner to enter the WAC's web system. On the web system that appears, configure performance data collection for wireless services.

  2. Choose Configuration > Wireless Services > AP Group. On the AP Group tab page, click Area_1 in the AP group list. Choose AP > AP System Profile > WMI Profile (Channel 1). Click Create, set Profile name to campusinsight, and click OK.

  3. Set Server address and Port to the southbound IP address and port number of CampusInsight, select the data types to be reported next to Reported monitoring data, and click Apply.
