Server configuration.

Fields

interface: Ipv4Addr

Local interface to bind.

port: u16

UDP port (default 0xBAC0 = 47808).

broadcast_address: Ipv4Addr

Directed broadcast address.

max_apdu_length: u32

Maximum APDU length accepted.

segmentation_supported: Segmentation

Segmentation support level.

Enforced, not just advertised: the dispatch loop reassembles inbound segmented requests only under BOTH/RECEIVE and transmits segmented responses only under BOTH/TRANSMIT (Clauses 5.4.5.1 and 5.4.5.3); anything else draws a SEGMENTATION_NOT_SUPPORTED Abort. The default is NONE, so a default-configured server refuses segmented traffic in both directions — set this to what the device should actually honor.

vendor_id: u16

Vendor identifier.

cov_retry_timeout_ms: u64

Timeout in ms before retrying a failed confirmed COV notification send (default 3000ms).

on_time_sync: Option<Arc<dyn Fn(TimeSyncData) + Send + Sync>>

Optional observer invoked after a time-synchronization request is accepted.

life_safety_operation_authorizer: Option<LifeSafetyOperationAuthorizer>

Optional LifeSafetyOperation authorization policy.

Absence is fail-closed: requests receive SERVICES / SERVICE_REQUEST_DENIED before object mutation.

audit_notification_sink: Option<ObjectIdentifier>

Exactly one explicitly configured Audit Log notification sink.

Absence is fail-closed; the server never selects a sink by database iteration order.

audit_notification_authorizer: Option<AuditNotificationAuthorizer>

Optional fast, nonblocking ConfirmedAuditNotification authorizer.

Absence, false, or a panic denies the request before mutation.

unconfirmed_audit_notification_authorizer: Option<UnconfirmedAuditNotificationAuthorizer>

Optional fast, nonblocking UnconfirmedAuditNotification authorizer.

Absence, false, or a panic silently denies the request before mutation.

dcc_password: Option<String>

Optional password required for DeviceCommunicationControl.

reinit_password: Option<String>

Optional password required for ReinitializeDevice.

enable_fault_detection: bool

Enable periodic fault detection / reliability evaluation. When true, the server invokes every object’s opt-in, object-owned reliability evaluation hook every 10 seconds. Stock objects currently inherit the no-op default.

This governs reliability evaluation only. Event Enrollment evaluation is configured separately via enable_event_enrollment.

enable_event_enrollment: bool

Enable periodic Event Enrollment evaluation (default true).

When true, the server re-reads the property each Event Enrollment object names in its Object_Property_Reference and applies the configured event algorithm. Startup: the task is spawned by start and its first pass runs immediately, then once per interval. Shutdown: stop aborts it and awaits the abort.

This switch governs the evaluation task; it is not the per-object Event_Detection_Enable property of ASHRAE 135-2020 Clause 13.2.2.1. Setting it false stops evaluation without performing the reset that clause requires of a disabled detector (Event_State to NORMAL, with the corresponding timestamp and acknowledgment state), so a device carrying active enrollments will hold whatever state it last detected.

Evaluation is a no-op on databases holding no Event Enrollment objects, so the default is on.

Successful enabled transitions commit Event_State, Acked_Transitions, and Event_Time_Stamps atomically and are then routed through the shared EventNotification sender. Event Enrollment message text remains intentionally absent, and exact event-specific notification values are deferred to the payload projection work.

event_enrollment_interval_secs: u64

Interval in seconds between Event Enrollment evaluation passes (default 10).

This is a sampling cadence with no basis in ASHRAE 135-2020, which prescribes no evaluation frequency and leaves acquisition of a monitored value a local matter (Clause 12.12). It is not the Time_Delay of an event algorithm, which is how long a condition must persist before a transition is indicated (Clause 13.3) — a coarse interval delays detection and can miss a condition that both appears and clears between two passes.

A value of 0 is clamped to one second. Ignored when enable_event_enrollment is false.
