Description: This attribute counts the number of invalid layer 2 frames For DPNSS 1, a frames is counted as invalid if - it is shorter than 3 octets or longer than 48 octets (excluding two octets of Cyclic Redundancy Check), or - it has an invalid bit combination in the Address Field, or - the Control Field is inconsistent with the Address Field, or - the type of data is invalid, or - it relates to time slot 0. For MCDN, a frame is counted as invalid if - it is shorter than 4 or longer than 264 octets (excluding two octets of Cyclic Redundancy Check), or - it has an invalid bit combination in the Address Field, or - it has missing or incorrect mandatory information elements. This count wraps to zero after reaching its maximum value.
What is btdsMcdnFrmInvalid?
Counts layer-2 frames rejected as invalid -- for MCDN specifically, frames outside the 4-264 octet range, a bad address field, or missing/incorrect mandatory information elements; a climbing count suggests link-layer corruption or a misconfigured peer PBX.
