Parameter descriptions :
Port
: The logical port for the settings contained in the same row.
Hold Advance
: 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.
Release Advance : 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.
Preemption Active : The value is active (TRUE) when preemption is operationally active for the Port, and idle
(FALSE) otherwise.
Hold Request
: The value is hold (TRUE) when the sequence of gate operations for the Port has executed a Set-
And-Hold-MAC operation, and release (FALSE) when the sequence of gate operations has executed a Set-And-
Release-MAC operation. The value of this object is release (FALSE) on system initialization.
Status Verify : The status of the MAC Merge sublayer verification for the given device.
LocPreemptsupport : The value is TRUE when preemption is supported on the port, and FALSE otherwise.
LocPreemptEnabled : The value is TRUE when preemption is enabled on the port, and FALSE otherwise.
LocPreemptActive : The value is TRUE when preemption is operationally active on the port, and FALSE
otherwise.
LocAddFragSize : The value of the 802.3br LocAddFragSize parameter for the port. The minimum size of
non-final fragments supported by the receiver on the local port. This value is expressed in units of 64 octets
of additional fragment length. The minimum non-final fragment size is: (LocAddFr 1) * 64 octets.
