32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Mist cloud data plane

In Mist architecture, management, AI/ML, and configuration run in the cloud, but user data traffic stays local at the AP or switch and is not tunneled through the cloud.

Outbound port for APs

Mist APs and switches reach the cloud over outbound HTTPS on TCP 443. No inbound firewall ports are required for cloud management to work.

Organization and site

An organization is the top-level Mist tenant containing sites. A site groups devices, WLANs, and policies, and each device belongs to one site at a time.

Claim code

A code generated in the Mist dashboard and entered on a device to bind it to an organization. APs use an org claim code; switches use an activation code.

Service Level Expectation (SLE)

A Mist metric model with a classifier defining success or failure, a 0-100 score, and root-cause classifiers. Wireless SLEs include coverage, capacity, roaming, and client health.

Marvis virtual network assistant

Mist's AI assistant that consumes SLE data, events, and telemetry to answer natural-language queries, surface root causes, and recommend fixes for network issues.

Anomaly detection baseline

Mist ML compares live behavior against learned baselines per site, AP, or client rather than fixed thresholds, reducing false positives and surfacing unusual changes.

SLE classifier

The rule that decides whether a client or device succeeded for a given SLE, such as whether a client connected, roamed cleanly, or met a throughput target.

Non-overlapping 2.4 GHz channels

In 2.4 GHz with 20 MHz channels, only channels 1, 6, and 11 are non-overlapping. Reusing these three across APs limits co-channel interference.

SNR target

SNR is received signal minus the noise floor. A common target for voice and real-time applications is 25 dB or higher, with RSSI better than about -67 dBm.

Channel width trade-off

Wider channels such as 80 or 160 MHz raise peak throughput but reduce the number of non-overlapping channels, increasing co-channel interference in dense deployments.

BSS coloring

A Wi-Fi 6 feature that tags frames with a BSS color so an AP can ignore overlapping transmissions from a different color, reducing unnecessary channel deferral.

AP onboarding prerequisites

To onboard a Mist AP: power it, give it DHCP and internet access, then claim it in the dashboard. The AP must reach the cloud over HTTPS 443 to be adopted.

Device profile

A Mist configuration object applied to individual APs or switches to override site settings, such as radio parameters, IP configuration, or DNS and NTP servers.

Zero-touch provisioning

A claimed Mist AP downloads its site configuration automatically on first cloud check-in, so no local CLI setup or manual configuration is required.

Mesh portal and point

In a Mist mesh, the portal AP has a wired uplink to the network, and mesh point APs extend coverage wirelessly by associating to the portal or other points.

WPA3-Personal SAE

WPA3-Personal uses Simultaneous Authentication of Equals, a password-authenticated key exchange that resists offline dictionary attacks better than WPA2-PSK.

Dynamic VLAN assignment

A WLAN can assign a client's VLAN from the RADIUS response rather than a static VLAN, letting identity or policy determine network segmentation per user.

Fast roaming 802.11r

802.11r speeds up roaming by pre-establishing keys with neighboring APs, reducing reauthentication time for voice and latency-sensitive clients moving between APs.

Guest captive portal

A guest WLAN can require a splash page before access, using click-through, voucher, or external portal methods to authenticate or collect acceptance.

Switch activation code

A code generated in Mist and entered on a supported switch to claim it to an organization, after which it can be assigned to a site and managed from the cloud.

Port profile

A Mist switch configuration template for a port that sets speed, duplex, PoE, VLAN membership, and STP behavior, applied to standardize switch ports.

PoE budget

The total power a switch can deliver to powered devices across its ports. Exceeding it can de-power ports, so plan per-AP PoE class against the budget.

Trunk versus access port

A trunk port carries multiple VLANs as tagged frames, typically to another switch or AP. An access port carries a single untagged VLAN to an endpoint.

Marvis Actions

A prioritized list of actionable issues in the Mist dashboard, each with a root cause and recommended fix, grouped by severity and category across sites.

Client connection timeline

Marvis client troubleshooting shows the sequence of association, authentication, DHCP, DNS, and roaming events, so you can pinpoint where a client failed.

Bad cable detection

Marvis can flag a bad Ethernet cable from CRC or error counters on a switch port, a common root cause of AP or wired client connectivity problems.

SLE root-cause classifier

When an SLE score drops, Marvis identifies the dominant failing classifier, such as DHCP failure or coverage, to point to the underlying cause.

Mist location services

Mist uses Wi-Fi and BLE from APs to locate and track assets and support engagement, with accuracy depending on AP density and calibration.

vBLE

Virtual BLE uses the AP's Wi-Fi radio to provide BLE-like location and engagement services on supported models without a dedicated BLE antenna.

Webhooks and REST API

Mist exposes a REST API and webhooks so telemetry, SLE metrics, alarms, and events can be exported to external monitoring, ticketing, or SIEM systems.

Alarm configuration

Alarms in Mist are configured per organization or site and can be forwarded through webhooks or integrations, letting operators route events to the right team.
