DESCRIPTION
"Represents an IEEE 802 MAC address represented in the
`canonical' order defined by IEEE 802.1a, EUI-64. EUI-48
converts to EUI-64 as specified by IEEE. The conversion
assigns values 255 and 254 to octets 3 and 4 respectively,
where octet 0 is the most significant and octet 7 the least.
For example, EUI-48 of AC:DE:48:23:45:67 would extend to
AC:DE:48:FF:FE:23:45:67."

"The value is the actual size of the

table size is less than or equal to the max table size.
This value SHOULD be reflect the number of entries in
the ieee8021AsAcceptableMasterTableDSMasterTable.
For a time-aware system that contains an ONU attached
to an IEEE 802.3 EPON link, the initialization value
is 1. For a time-aware system that does not contain an
ONU attached to an IEEE 802.3 EPON link, the
initialization value is 0."
