Definitions of Managed Objects for Packet Sampling
<draft-ietf-ipfix-psamp-mib-04.txt>
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.

1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
