Marvis Minis - AI Native Digital Experience Twin
Marvis Minis operates as a virtual client on the network, learning the network configuration through unsupervised machine learning. It simulates user connections, verifies network connectivity and application reachability, and strongly supports the transition from reactive to proactive operations by enabling early detection and identification of issues that could affect user experience.
Physical Space: Collects data from user traffic. Visualizes and analyzes UX, collecting necessary information on a client-by-client basis.
Digital Space: Collects data from virtual clients. Simulates issues before they occur in the real environment, enabling proactive problem detection.
A Digital Twin is a representation of a physical entity in a digital (virtual) space. Marvis Minis acts as the user's digital twin, performing simulations, verification, analysis, and predictions in the digital space.
Reactive vs Proactive
Reactive (Post-event reactive response): It is difficult to confirm network status before user connection. It is practically impossible to confirm connectivity from all APs.
Proactive (Pre-emptive proactive response): Confirms network status before user connection. Automatically confirms connectivity from all APs.
Diagram Description:
The diagram shows a network infrastructure with multiple branches (A, B, X) connected via WAN. The reactive side shows user reports of connectivity issues. The proactive side shows Marvis Minis automatically verifying connectivity for all APs, enabling pre-emptive issue resolution.
How Marvis Minis Works
Introduction: Simple Deployment
- Subscription is integrated with Marvis for Wireless. No additional investment is required for Marvis Minis.
- No need for additional sensor installation. Marvis Minis is deployed on Mist APs.
- Can be used by upgrading to Marvis Minis compatible firmware (version 0.14.29313 or later).
Automatic Testing:
Once all APs' firmware are upgraded to version 0.14.29313 or later, Marvis Minis tests will automatically start approximately one hour after the upgrade.
- Learns all APs, WLANs, switches, and active VLANs within the site and automatically creates tests (DHCP/ARP/DNS/Application Reachability).
- Tests are executed every hour (manual execution is also possible).
- Organization-wide or site-specific settings (Disable/Custom URL/Excluded VLAN) are available.
- Data obtained by Marvis Minis is used in a multifaceted and complementary manner.
- Wireless SLE > Successful Connect > Timeline
- Marvis Actions > Connectivity
- Filter using Marvis Query Languages.
Marvis Minis starts automatically (version 0.14.29313 and later). Custom URLs and Excluded VLANs can be configured. Manual (on-demand) execution can be performed from the site-specific screen (next page).
Configuration
Organization-wide Settings:
From [Organization], click [Settings], then configure in [Marvis Minis].
- Disable Marvis Minis: Option to disable Marvis Minis.
- Custom URLs: Add custom URLs for testing.
- VLANs: Specify VLANs for testing.
- Excluded VLANS: Exclude specific VLANs from testing.
Marvis Minis starts automatically with firmware version 0.14.29313 and later. Disabling, Excluded VLAN, and Custom URL settings are possible. These can be overridden at the site level.
Site-specific Settings:
From [Organization], click [Site Configuration], select a site, and then configure Marvis Minis to override the organization settings.
Refer to the previous page for detailed configuration.
Marvis Minis Test Procedures
Marvis Minis verifies each network service for all active VLANs on the enabled wireless LAN, confirming that the site is operational.
Verified Network Services:
- DHCP
- ARP
- DNS
- Application Reachability
Simulating User Connection:
- Sends a DHCP Request for the client VLAN, verifying if the AP can obtain an IP address (APs send both broadcast discovery and unicast updates).
- Generates an ARP Request for the gateway.
- Resolves DNS queries for all DNS server IP addresses received via DHCP Offer.
- Verifies application reachability and internet reachability. Uses default internet connection URLs to verify application reachability. Custom applications can be defined in the organization or site settings.
- Explicitly releases the DHCP lease on the VLAN under test.
Example URLs for testing: captive.apple.com, connectivitycheck.gstatic.com, office.com, teams.microsoft.com
Identify the Scope of the Problem
When Marvis Minis detects a failure in DHCP, ARP, DNS, or application reachability on any VLAN, it performs the following checks to determine the scope of the problem (e.g., affected APs, switches, or the entire site):
Where is the problem?
- Specific AP?
- Specific Switch? Floor?
- Site?
- External?
- Re-tests connectivity with the AP where the failure occurred.
- Tests if other APs connected to the same switch are experiencing the problem.
- Tests if the problem occurs with APs connected to different switches.
- Confirms if the scope of the problem is limited to APs, switches, or the entire site for that VLAN.
Marvis Minis automatically expands the scope to find the problem area = AI Native Digital Experience Twin.
Note on Client VLANs
If the client VLAN is the same as the AP management VLAN, the AP has already obtained an IP address, and ARP is considered resolved. In such scenarios, Marvis Minis only verifies DNS and Application reachability; it does not send DHCP requests or re-verify ARP resolution for the AP management VLAN.
Diagram Description:
The dashboard shows test results. For client VLANs that are the same as the AP management VLAN, DHCP/ARP status might be 'Not Validated', while DNS/Application status is 'Validated'.
Marvis Minis Dashboard
Click [Marvis] then [Marvis Minis] to display the Marvis Minis Dashboard.
The dashboard provides a timeline view (1 week + 1 day) and simulation results, allowing users to see site-aggregated data by clicking.
Marvis > Marvis Minis > Connectivity
From the [Dashboard], select [Connectivity] from the dropdown menu to display the test results for the entire organization. You can also view site-specific data by selecting it from the site list.
Diagram Description:
The dashboard shows a timeline of test results. Clicking on a failed test (indicated by a clip icon) allows downloading packet captures, which are automatically obtained when a packet capture is available.
Marvis > Marvis Minis > Connectivity (Detailed Test Results)
On the detailed test page, clicking on a failed test (red) allows you to download the automatically captured packet data. Review the packet capture and perform necessary actions.
Diagram Description:
The packet capture shows DHCP Discover requests from two APs on VLAN 2. If the DHCP Offer is not received, network or DHCP server verification is required.
Packet captures are automatically obtained, enabling proactive troubleshooting without waiting for user reports.
Marvis Actions > Connectivity
Failed test results from Marvis Minis are provided to Marvis Actions and can be confirmed under Connectivity.
Diagram Description:
The Marvis Actions interface shows categories like Connectivity, Authentication Failure, DHCP Failure, ARP Failure, and DNS Failure. Clicking on a DHCP Failure entry provides recommended actions, such as checking the DHCP server's status.
DHCP Failure for VLAN 2 can be confirmed here, linking back to Marvis Minis results.
Monitor > Service Levels > Wireless > Successful Connects > Timeline
Monitor > Service Levels > Wireless > Successful Connects > Timeline displays the execution results of Marvis Minis.
Diagram Description:
The timeline shows various metrics like Failures, Attempts, Association, Authorization, DHCP, ARP, and DNS. It also displays affected items and system changes.
Marvis Query Languages
Marvis Query Languages can be used to filter Marvis Minis test output results.
Example: Displaying the count (COUNT) and list (LIST) of Marvis Minis test results.
COUNT ApEvents WITH ApEventType Marvis-Connectivity-TestLIST ApEvents WITH ApEventType Marvis-Connectivity-Test
Diagram Description:
The query results show a list of Marvis Connectivity Tests with details such as time, type, AP, and event details.
