According to the web search results, TCP/443 is the port that must be allowed on your company’s firewall for AP access to the Mist cloud. TCP/443 is the port that is used for HTTPS, which is a secure version of HTTP that encrypts the data sent between the client and the server1. Mist APs use HTTPS to communicate with the Mist cloud and receive their configuration, firmware, and policies2. TCP/443 is also the port that is used for ep-terminator, which is a service that provides encrypted tunneling between Mist APs and the Mist cloud3. Therefore, TCP/443 is the port that must be allowed on your company’s firewall for AP access to the Mist cloud.

The step that you would take to immediately find out the status of the Mist cloud is to visit https://status.mist.com. This is the official website that provides real-time information and updates on the availability and performance of the Mist cloud services, such as the Mist portal, the Mist API, the Mist AI engine, and the Mist regions. You can also subscribe to receive notifications via email, SMS, or webhook when there are any incidents or maintenance events affecting the Mist cloud.

A user called a help desk to report a Wi-Fi issue. In this scenario, the information that must be provided for Marvis to troubleshoot the issue are the MAC address of the client device and the time of the incident. These are two of the essential parameters that Marvis needs to identify and analyze the wireless client and its connection history.
The MAC address of the client device is a unique identifier that allows Marvis to locate and track the client on the wireless network. The MAC address can be found on the device settings, label, or sticker, depending on the device type. The MAC address can also be obtained from the Mist portal or the Mist AI App by searching for the client name or IP address.
The time of the incident is the approximate date and time when the user experienced the Wi-Fi issue. The time of the incident can help Marvis narrow down the scope of the troubleshooting and focus on the relevant data and events. The time of the incident can be specified in various formats, such as “today”, “yesterday”, “last week”, “10 minutes ago”, “5 pm”, etc.
To troubleshoot a Wi-Fi issue using Marvis, you can use phrases such as “troubleshoot client <MAC address> on <time>” or “how was client <MAC address> on <time>” in the Marvis Conversational Assistant window. Marvis will show you the details of the client’s connection status, performance, issues, and recommendations.

According to the [Service Level Expectations] page, Service Level Expectations (SLEs) are a set of metrics that measure the quality and performance of the wireless network from the user’s perspective. SLEs can help network administrators monitor, troubleshoot, and optimize their network by providing real-time and historical data and analytics. SLEs can also help network administrators identify and resolve issues before they impact the user experience.
There are seven SLEs that are supported by Mist: Successful Connects, Time to Connect, Capacity, Coverage, Throughput, Roaming, and WAN. Each SLE has a target value and a threshold value that can be customized according to the network requirements. The SLE score is calculated as the percentage of clients that meet or exceed the target value for each SLE.
Two SLEs that report DHCP problems are Successful Connects and Time to Connect. DHCP (Dynamic Host Configuration Protocol) is a protocol that assigns IP addresses and other network configuration parameters to devices on a network. DHCP problems can occur when a device fails to obtain an IP address from the DHCP server or when the DHCP server is slow or unreachable.
Successful Connects is an SLE that measures the percentage of clients that successfully connect to the wireless network within a specified time frame. Successful Connects can report DHCP problems by showing the number of clients that fail to connect due to DHCP errors, such as DHCP timeout, DHCP NAK, or DHCP decline. Successful Connects can also show the root cause analysis and recommended actions for resolving DHCP problems.
Time to Connect is an SLE that measures the average time it takes for a client to connect to the wireless network from the moment it sends a probe request to the moment it receives an IP address from the DHCP server. Time to Connect can report DHCP problems by showing the breakdown of the connection time into different stages, such as probe, auth, assoc, EAPOL, and DHCP. Time to Connect can also show the outliers and trends for each stage and identify if there are any delays or failures in the DHCP process.

According to the web search results, Marvis Actions is a feature that automatically detects and reports network problems that affect the user experience in an organization1. Marvis Actions uses the Mist AI to identify the root cause of issues and provide recommended solutions or automated fixes1. Marvis Actions can provide insight into issues across the wired, WAN, and wireless networks, at the managed service provider (MSP) level, organization level, and site level1. Marvis Actions can help network administrators monitor, troubleshoot, and optimize their network by providing real-time and historical data and analytics1.
