"An object that indicates the mode of operation
of the Reconciliation Sublayer for Point-to-Point
Emulation (see [802.3ah], clause 65.1). unknown(1) value
is assigned in initialization; true state or type is not
yet known. olt(2) value is assigned when the sublayer is
operating in OLT mode. onu(3) value is assigned when the
sublayer is operating in ONU mode.
This object is applicable for an OLT, with the same
value for all virtual interfaces, and for an ONU."

DESCRIPTION
"This table defines the list of statistics counters of
[802.3ah], clause 65, OMPEmulation sublayer.
Each object has a row for every virtual link denoted by
the corresponding ifIndex.
The LLID field, as defined in the [802.3ah], is a 2-byte
register (15-bit field and a broadcast bit) limiting the
number of virtual links to 32768. Typically the number
of expected virtual links in a PON is like the number of
ONUs, which is 32-64, plus an additional entry for
broadcast LLID (with a value of 0xffff)."
