Remote Network Monitoring (RMON) Protocol Identifiers for IPv6 and
Multi Protocol Label Switching (MPLS)

Status of this Memo

This memo provides information for the Internet community. It does
not specify an Internet standard of any kind. Distribution of this
memo is unlimited.

Abstract

This memo defines additional (to those in RFC 2896) protocol
identifier examples for IP version 6 and MPLS protocols. These can
be used to produce valid protocolDirTable INDEX encodings, as defined
by the Remote Network Monitoring MIB (Management Information Base)
Version 2 [RFC2021] and the RMON Protocol Identifier Reference
[RFC2895].

This document contains additional (to those in RFC 2896) protocol
identifier macros for well-known protocols. A conformant
implementation of the RMON-2 MIB [RFC2021] can be accomplished
without the use of these protocol identifiers, and accordingly, this
document does not specify any IETF standard. It is published to
encourage better interoperability between RMON-2 agent
implementations, by providing RMON related IPv6 and MPLS protocol
information.

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 accessed through the Simple Network Management
Protocol (SNMP). Objects in the MIB are defined using the mechanisms
defined in the Structure of Management Information (SMI). This memo
specifies a MIB module that is compliant to the SMIv2, which is
described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579]
and STD 58, RFC 2580 [RFC2580].

2. Overview

This memo defines basic protocol identifiers for IP version 6 and
MPLS protocols.

The "Remote Network Monitoring MIB Protocol Identifier Macros"
[RFC2896], defines various protocol identifiers. The syntax of the
protocol identifier descriptor is defined in the RMON Protocol
Identifier Reference [RFC2895]. The reader should be familiar with
these documents.

The intent of this document is not to adapt each protocol identifier
defined in the RFC 2895 and in the RFC 2896 to IP version 6, but to
define protocol identifiers for IP version 6 protocols and for MPLS
protocol.

3. Relationship to the Remote Network Monitoring MIB

RMON MIB implementations use protocol identifiers to describe
unambiguous capabilities in protocolDirTable entries.

4. MPLS layer protocol identifiers

This section defines protocol identifiers for MPLS with unambiguous
names to distinguish MPLS Unicast from MPLS Multicast.

CHILDREN
"Children of 'ip6' are selected by the value in the Protocol
field (one octet), as defined in the PROTOCOL NUMBERS table
within the Assigned Numbers Document.

The value of the Protocol field is encoded in an octet string as
[ 0.0.0.a ], where 'a' is the protocol field.
Children of 'ip6' are encoded as [ 0.0.0.a ], and named as 'ip6
a' where 'a' is the protocol field value. For example, a
protocolDirID-fragment value of:
0.0.0.1.0.0.0.41.0.0.0.58

defines an encapsulation of IPv6-ICMP (ether2.ip6.icmp6)"
ADDRESS-FORMAT
"16 octets of the IPv6 address, in network byte order. Each ip
packet contains two addresses, the source address and the
destination address."
DECODING
"Note: ether2.ip.ipip6.udp is a different protocolDirID than
ether2.ip6.udp, as identified in the protocolDirTable. As such,
two different local protocol index values will be assigned by
the agent. E.g., (full INDEX values shown):
ether2.ip.ipip6.udp =
16.0.0.0.1.0.0.8.0.0.0.0.41.0.0.0.17.4.0.0.0.0
ether2.ip6.udp =

6. Security Considerations

This document contains textual descriptions of well-known networking
protocols, not the definition of any networking behavior. As such,
no security considerations are raised by its publication.
