   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 [RFC 2021] and the RMON Protocol Identifier Reference
   [RFC 2895].

   This document contains additional (to those in RFC 2896) protocol
   identifier macros for well-known protocols.  A conformant
   implementation of the RMON-2 MIB [RFC 2021] 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.

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 [RFC 3410]. 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 [RFC 2578], STD 58, RFC 2579 [RFC 2579] and STD 58, RFC 2580 [RFC 2580]. 2. Overview This memo defines basic protocol identifiers for IP version 6 and MPLS protocols. The "Remote Network Monitoring MIB Protocol Identifier Macros" [RFC 2896], defines various protocol identifiers. The syntax of the protocol identifier descriptor is defined in the RMON Protocol Identifier Reference [RFC 2895]. 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. Stephan & Palet Informational PAGE 2 top

RFC 3919 RMON Protocol Identifiers for IPv6 and MPLS October 2004 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 = 12.0.0.0.1.0.0.0.41.0.0.0.17.3.0.0.0 " REFERENCE "RFC 2460 [RFC 2460] defines the Internet Protocol version 6; The following URL defines the authoritative repository for the PROTOCOL NUMBERS Table: http://www.iana.org/assignments/protocol-numbers" ::= { ether2 0x86DD, 802-1Q 0x86DD, mplsu 41, mplsm 41 } ipip6 PROTOCOL-IDENTIFIER PARAMETERS { } ATTRIBUTES { } DESCRIPTION "IPv6 in IPv4 Tunneling" Stephan & Palet Informational PAGE 4 top
