column
r/w
Tenth of percent Unsigned32
A level of buffer occupancy in a dual-queue deployment,
at or above which congestion on the outbound link is declared.
This attribute specifies the medium threshold location
in percentage of the STQ size.
The allowed range is [stqLowThreshold + mtuSize,
stqHighThreshold - mtuSize].
The default value is 0.5 * (stqHighThreshold + stqLowThreshold).
