mpanlDlciErrorLongBytesFromIf
mpanl Dlci Error Long Bytes From If
This attribute counts the bytes received with number of octets in the information field greater than the subscribed maximum. When the count reaches maximum it wraps to zero. Bytes whose lengths are greater than the hardware receive buffer are ignored by the hardware and are therefore not included in this count.
