Definitions of Managed Objects for Middlebox Communication
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
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 a set of managed objects that allow
configuring middleboxes, such as firewalls and network address
translators, in order to enable communication across these devices.
The definitions of managed objects in this documents follow closely
the MIDCOM semantics defined in RFC 5189.
