frNniDlciErrorLongFrmFromIf
Frame Relay Nni Dlci Error Long Frm From If
This attribute counts the frames received with number of octets in the information field greater than the subscribed maximum. When the count reaches maximum it wraps to zero. Frames whose lengths are greater than the hardware receive buffer are ignored by the hardware and are therefore not included in this count.
