# 8021XSecondActiveEthernet The payload that configures the second wired, active Ethernet interface. ``` WiFi.EAPClientConfiguration 8021XSecondActiveEthernet ``` ## Discussion Specify `com.apple.secondactiveethernet.managed` as the payload type. This payload’s contents contain these profile-specific keys: - Interface (String): This payload uses the value `SecondActiveEthernet`. - 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 SecondActiveEthernet Password password ProxyType None SetupModes System PayloadIdentifier com.example.my8021Xsecaepayload PayloadType com.apple.secondactiveethernet.managed PayloadUUID 38791a67-90ca-40e5-bddd-fc3dc85a447e PayloadVersion 1 PayloadDisplayName 802.1x Second Active Ethernet PayloadIdentifier com.example.myprofile PayloadType Configuration PayloadUUID 50939eda-ff93-4e0c-907b-159d8d5c1a1a PayloadVersion 1 ``` --- Copyright © 2026 Apple Inc.
