             The rows in the table for an ONU interface are created
             at system initialization.

             and the row corresponding to the broadcast virtual link
             are created at system initialization.
             A row in the table corresponding to the ifIndex of a

             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)."

    DESCRIPTION
            "An entry in the table of statistics counters of
             [802.3ah], clause 65, OMPEmulation sublayer.
             Rows exist for an OLT interface and an ONU interface.
             A row in the table is denoted by the ifIndex of the link
             and it is created when the ifIndex is created.
             The rows in the table for an ONU interface are created
             at system initialization.
             The row in the table corresponding to the OLT ifIndex
             and the row corresponding to the broadcast virtual link
             are created at system initialization.
             A row in the table corresponding to the ifIndex of a
             virtual links is created when a virtual link is
             established (ONU registers) and deleted when the virtual
             link is deleted (ONU deregisters)."
