filterPktDataNotMask
Module: RMON-MIB
OID (symbolic): RMON-MIB::filterPktDataNotMask
OID (numeric): 1.3.6.1.2.1.16.7.1.1.6
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-create
Description:
The inversion mask that is applied to the match process. After adjusting this mask for the offset, those relevant bits in the received packet that correspond to bits cleared in this mask must all be equal to their corresponding bits in the filterPktData object for the packet to be accepted. In addition, at least one of those relevant bits in the received packet that correspond to bits set in this mask must be different to its corresponding bit in the filterPktData object.
For the purposes of the matching algorithm, if the associated filterPktData object is longer than this mask, this mask is conceptually extended with '0' bits until it reaches the length of the filterPktData object.
This object may not be modified if the associated filterStatus object is equal to valid(1).
What is filterPktDataNotMask?
This OID stores a binary mask used to selectively match certain bits in network packets as they arrive at the monitoring point. It works like a partial pattern matcher—some bits in packets must match while others are ignored based on this mask. A network analyst might use this to capture only packets with specific headers while ignoring other variations, reducing data volume.
