A table containing a set of frame preemption parameters, one for each priority value. All writeable objects in this table must be persistent over power up restart/reboot. Reference: 6.7.2, 12.30.1
IEEE8021PbbComponentIdentifierThe component identifier is used to distinguish between the multiple virtual Bridge instances within a PB or PBB. Each virtual Bridge instance is called a component. In simple situations where there is only a single component the default value is 1. The component is identified by a component identifier unique within the BEB and by a MAC address unique within the PBBN. Each component is associated with a Backbone Edge Bridge (BEB) Configuration managed object.Reference: 12.3 l) (1..4294967295) · Unsigned32 · hint d

ieee8021BridgeBasePort
IEEE8021BridgePortNumberAn integer that uniquely identifies a Bridge Port, as specified in 17.3.2.2. This value is used within the spanning tree protocol to identify this port to neighbor Bridges.Reference: 17.3.2.2 (1..65535) · Unsigned32 · hint d
The port number of the port for which this entry contains Bridge management information. Reference: 12.4.2.1
ieee8021PreemptionPriority
1.3.111.2.802.1.1.29.1.1.1.1.1
IEEE8021PriorityValueAn IEEE 802.1Q user priority value.Reference: 12.13.3.3 (0..7) · Unsigned32 · hint d
The priority number associated with the row of the table.
A row in this table is created for each priority value. Reference: 6.7.2, 12.30.1
ieee8021FramePreemptionAdminStatus
1.3.111.2.802.1.1.29.1.1.1.1.2
INTEGER1 = express2 = preemptible · Integer32
The value of the framePreemptionAdminStatus parameter for the traffic class.
The default value of the framePreemptionAdminStatus parameter is express (1).
The value of this object MUST be retained across reinitializations of the management system. Reference: 6.7.2, 12.30.1

ieee8021FramePreemptionHoldAdvance
1.3.111.2.802.1.1.29.1.1.2.1.1
Unsigned32
The value of the holdAdvance parameter for the Port in nanoseconds.
There is no default value; the holdAdvance is a property of the underlying MAC. Reference: 6.7.2, 12.30.1.2
ieee8021FramePreemptionReleaseAdvance
1.3.111.2.802.1.1.29.1.1.2.1.2
Unsigned32
The value of the releaseAdvance parameter for the Port in nanoseconds.
There is no default value; the releaseAdvance is a property of the underlying MAC. Reference: 6.7.2, 12.30.1.3
ieee8021FramePreemptionActive
1.3.111.2.802.1.1.29.1.1.2.1.3
INTEGER1 = idle2 = active · Integer32
The value is active (2) when preemption is operationally active for the Port, and idle (1) otherwise. Reference: 6.7.2, 12.30.1.4
ieee8021FramePreemptionHoldRequest
1.3.111.2.802.1.1.29.1.1.2.1.4
INTEGER1 = hold2 = release · Integer32
The value is hold (1) when the sequence of gate operations for the Port has executed a Set-And-Hold-MAC operation, and release (2) when the sequence of gate operations has executed a Set-And-Release-MAC operation. The value of this object is release (2) on system initialization. Reference: 6.7.2, Table 8-7, 12.30.1.5
