To set up a new WLAN that is Open Access and prevents connected clients from communicating with each other, you should use theConfigure Isolationfeature. This feature, often referred to as client isolation, ensures that each client can only communicate with the access point and not with other clients on the same WLAN.

Juniper Networks Mist Edge FAQs

Mist Cloud Communication Protocol: The Mist cloud platform uses HTTPS (Hypertext Transfer Protocol Secure) to communicate with connected access points. This ensures that the data sent and received is encrypted and secure, adhering to modern security standards​(Juniper Networks)​​(CertEnsure)​.

Security and Reliability: Using HTTPS provides a secure channel over which configuration changes, updates, and monitoring data can be safely transmitted between the Mist cloud and the access points. This protocol is widely accepted and trusted for secure communications over the internet.

Incorrect Options:

MQTT: While MQTT is a lightweight messaging protocol often used in IoT, it is not the protocol used by Mist cloud for AP communication.

SSH: Secure Shell (SSH) is primarily used for secure remote command-line access and not for the primary communication between Mist cloud and APs.

PPTP: Point-to-Point Tunneling Protocol (PPTP) is used for implementing VPNs and is not relevant to the communication between Mist cloud and access points.

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.

Mist Administrative Logins: Mist administrative logins can utilize Single Sign-On (SSO), allowing administrators to log in using their corporate credentials, enhancing security and ease of access.

Guest User Access: Guest user access cannot use SSO, as SSO is intended for internal users and administrators rather than external guest users who access the network.

For Marvis, Mist AI’s virtual network assistant, to provide a visualization of low coverage and low-capacity issues within the network, a floor plan is required. This enables Marvis to map the coverage and capacity data to specific locations within the physical space, allowing for precise identification and troubleshooting of network issues.

Understanding Location Determination in Mist:

Mist uses advanced methods to determine the location of clients in an indoor setting.

Possible Methods:

Triangulation: Uses angles to determine position, but not typically used by Mist.

GPS: Not feasible indoors due to signal limitations.

Probability Surface: Involves calculating the probability of a client's location, but not the primary method used.

Trilateration: Uses the distance from multiple known points to determine the exact location.

Mist's Method:

Mist primarily uses trilateration to determine the location of clients by measuring the distance from at least three access points.

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.

Time Zone Importance: Setting the correct time zone for a Mist site ensures that all events and logs are timestamped accurately according to the local time of the site. This is crucial for effective monitoring and troubleshooting.

Facilitation of Troubleshooting: By aligning event timestamps with the local time, network administrators can correlate events more easily with specific incidents reported by users, thereby simplifying the troubleshooting process.
