    abstract =  {This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes extensions to the IPFIX SELECTOR MIB module {[}I-D.dkcm-ipfix-rfc5815bis{]}. For IPFIX implementations that use packet Sampling (PSAMP) techniques as described in {[}RFC5475{]}, this memo defines the PSAMP MIB module containing managed objects for providing information on applied packet selection functions and their parameters.},
