ieee8021FramePreemptionHoldAdvance
Module: IEEE8021-Preemption-MIB
OID (symbolic): IEEE8021-Preemption-MIB::ieee8021FramePreemptionHoldAdvance
OID (numeric): 1.3.111.2.802.1.1.29.1.1.2.1.1
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: 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.
What is ieee8021FramePreemptionHoldAdvance?
This read-only Unsigned32 reports the holdAdvance parameter for a port, in nanoseconds, a property fixed by the underlying MAC hardware rather than configurable. It tells an admin how much lead time the MAC needs before a Set-And-Hold-MAC operation actually takes effect when scheduling preemptible traffic. For example, a NIC might report a holdAdvance of 32 nanoseconds, reflecting its guard-band timing for frame preemption.
