The Mist Edge device is responsible for detecting Layer 1 issues, such as bad cable actions, within the Marvis Actions framework.

Mist Edge integrates with Marvis AI to provide detailed insights into network health, including physical layer issues like faulty cables, which can impact network performance.

By identifying and alerting administrators to these problems, Mist Edge helps maintain the integrity and reliability of the network infrastructure.

Reference: Juniper Networks documentation on Mist Edge and its diagnostic capabilities.

For capacity, coverage, and throughput Service Level Expectations (SLEs) in Mist AI, throughput is measured in Mbps. This unit measures the rate at which data is successfully delivered over the wireless network, providing a clear indication of network performance and user experience. Mist AI tracks these metrics to ensure the network meets the required performance standards.

AP and RADIUS Server Communication: By default, the communication between an Access Point (AP) and a RADIUS server is not encrypted. This can be configured to be encrypted, but it is not the default setting.

Wi-Fi Client and AP Communication: By default, the communication between a Wi-Fi client and an AP is encrypted, typically using WPA2 or WPA3, which ensures the data exchanged over the wireless network is secure.

Agile Feature Updates and Bug Fixes: Juniper Mist's microservices architecture allows for rapid development and deployment of new features and bug fixes. This agility ensures that improvements and fixes can be rolled out continuously without impacting the entire system​(CertsHero)​.

Increased Scalability: The microservices approach enables horizontal scaling, where individual services can be scaled independently based on demand. This allows the system to handle increased load efficiently​(CertsHero)​.

Implementation of Machine Learning: Juniper Mist's architecture leverages machine learning within its microservices to provide intelligent network management and predictive analytics. This enhances the capability of the system to optimize performance and troubleshoot issues proactively​(Juniper Networks)​​(CertsHero)​.

The exhibit displays an interaction sequence typical of RESTful APIs, which use HTTP methods such as GET, POST, PUT, and DELETE to perform operations on resources. RESTful APIs are characterized by their statelessness and reliance on standard HTTP methods, making them a popular choice for web services and applications.

RESTful Web Services Overview

The maximum number of nodes supported in a Mist Edge high availability cluster is three.

This configuration ensures high availability and redundancy, providing resilience and reliability for network operations.

By having three nodes, the cluster can continue to operate effectively even if one node fails, ensuring minimal disruption.

Reference: Juniper Networks documentation on Mist Edge high availability cluster configurations.

Identify the Changes: Radio Resource Management (RRM) changes and their timings.

RRM Changes:

Channel and power settings based on long-term statistics.

RF template changes to channel width.

Changes triggered by SSID scheduling.

Changes triggered by DFS events.

Timing of Changes:

Long-term RRM changes to channel and power settings are typically scheduled once a day to avoid disrupting network performance.

Conclusion:

Channel and power settings across a site based on long-term statistics and baselines are made once a day between 2:00 AM and 3:00 AM local time.

In the context of Mist management, "brownfield" switches refer to those that are already configured and deployed in a network, while "greenfield" switches are new and have no pre-existing configuration.

Mist supports the integration and management of both brownfield and greenfield switches within the same site. The crucial requirement is that all switches, regardless of their initial state, must be running a version of Junos that is supported by Mist.

This compatibility ensures that Mist can apply policies, configurations, and monitoring uniformly across all devices, facilitating a seamless management experience.

Reference: Juniper Networks documentation on Mist AI and Junos compatibility requirements.

Site Level: WLAN objects can be created at the site level, allowing specific configurations for different locations within an organization. This helps in customizing WLAN settings based on the unique requirements of each site.

Org Level: WLAN objects can also be created at the organization level, which provides a standardized configuration that can be applied across multiple sites. This ensures consistency in WLAN settings throughout the entire organization.

Site and Org Level Configration.

Coverage Hole: Marvis Actions can identify coverage holes where the wireless signal is weak or absent, indicating potential areas that need additional access points or adjustments.

Health Check Failed: This action indicates that the health check, which monitors the performance and connectivity of an access point, has failed, suggesting issues that need to be addressed.

Juniper Networks Mist Edge FAQs

Wi-Fi Location-Based Services (LBS) provided by Mist require the User Engagement subscription.

This subscription includes features that enhance user interactions and engagement, such as location services, which are critical for delivering personalized and location-aware experiences.

By leveraging Wi-Fi LBS with the User Engagement subscription, organizations can offer advanced services like wayfinding, asset tracking, and location analytics.

Reference: Juniper Networks documentation on subscriptions required for Wi-Fi LBS and User Engagement services.

Enable Two-Factor Authentication (2FA): Adding 2FA to administrator logins significantly enhances security by requiring a second form of verification in addition to the password, making unauthorized access more difficult.

Enable a Password Policy: Implementing a strong password policy ensures that passwords meet certain complexity and length requirements, reducing the risk of brute force attacks.
