# 8021XThirdActiveEthernet The payload that configures the third wired, active Ethernet interface. ``` WiFi.EAPClientConfiguration 8021XThirdActiveEthernet ``` ## Discussion Specify `com.apple.thirdactiveethernet.managed` as the payload type. This payload’s contents contain these profile-specific keys: - Interface (String): This payload uses the value `ThirdActiveEthernet`. - EAPClientConfiguration ([`WiFi.EAPClientConfiguration`](/documentation/DeviceManagement/WiFi/EAPClientConfiguration-data.dictionary)): The dictionary that defines the enterprise profile for the network. - SetupModes (String): The type of connection mode, which is either “System” or “Loginwindow.” “System” is the default. Payloads with `active` in their name apply to Ethernet interfaces that are working at the time of profile installation. If there’s no active Ethernet interface working, this payload configures the interface with the highest service-order priority. ### Profile availability ||| |--------------------------|-----| |Device channel |macOS| |User channel |macOS| |Allow manual install |macOS| |Requires supervision |N/A | |Requires user-approved MDM|N/A | |Allowed in user enrollment|macOS| |Allow multiple payloads |N/A | ### Profile example ```plist PayloadContent AuthenticationMethod AutoJoin CaptiveBypass EAPClientConfiguration AcceptEAPTypes 25 UserName user UserPassword password EncryptionType WPA2 HIDDEN_NETWORK Interface ThirdActiveEthernet Password password ProxyType None SetupModes System PayloadIdentifier com.example.my8021xthirdaepayload PayloadType com.apple.thirdactiveethernet.managed PayloadUUID a001a09a-d40d-4535-83ea-b21c409a5949 PayloadVersion 1 PayloadDisplayName 802.1x Third Active Ethernet PayloadIdentifier com.example.myprofile PayloadType Configuration PayloadUUID 77d92cd3-d303-4e2e-8c67-b6e67b30ba2c PayloadVersion 1 ``` --- Copyright © 2026 Apple Inc.
