Network Working Group S. Waldbusser Request for Comments: 1513 Carnegie Mellon University Updates: 1271 September 1993

     Token Ring Extensions to the Remote Network Monitoring MIB

Status of this Memo

 This RFC 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" for the standardization state and status
 of this protocol.  Distribution of this memo is unlimited.

Abstract

 This memo defines extensions to the Remote Network Monitoring MIB for
 managing 802.5 Token Ring networks.
 The Remote Network Monitoring MIB, RFC 1271, defines a framework for
 remote monitoring functions implemented on a network probe.  That MIB
 defines objects broken down into nine functional groups.  Some of
 those functional groups, the statistics and the history groups, have
 a view of the data-link layer that is specific to the media type and
 require specific objects to be defined for each media type.  RFC 1271
 defined those specific objects necessary for Ethernet.  This
 companion memo defines those specific objects necessary for Token
 Ring LANs.
 In addition, this memo defines some additional monitoring functions
 specifically for Token Ring.  These are defined in the Ring Station
 Group, the Ring Station Order Group, the Ring Station Configuration
 Group, and the Source Routing Statistics Group.

1. The Network Management Framework

 The Internet-standard Network Management Framework consists of three
 components.  They are:
    STD 16, RFC 1155 [1] which defines the SMI, the mechanisms used
    for describing and naming objects for the purpose of management.
    STD 16, RFC 1212 [2] defines a more concise description mechanism,
    which is wholly consistent with the SMI.
    STD 17, RFC 1213 [3] which defines MIB-II, the core set of managed
    objects for the Internet suite of protocols.
    STD 15, RFC 1157 [4] which defines the SNMP, the protocol used for
    network access to managed objects.
 The Framework permits new objects to be defined for the purpose of
 experimentation and evaluation.
 Managed objects are accessed via a virtual information store, termed
 the Management Information Base or MIB.  Within a given MIB module,
 objects are defined using STD 16, RFC 1212's OBJECT-TYPE macro.  At a
 minimum, each object has a name, a syntax, an access-level, and an
 implementation-status.
 The name is an object identifier, an administratively assigned name,
 which specifies an object type.  The object type together with an
 object instance serves to uniquely identify a specific instantiation
 of the object.  For human convenience, we often use a textual string,
 termed the object descriptor, to also refer to the object type.

Waldbusser [Page 2] RFC 1513 Token Ring Extensions to RMON MIB September 1993

 The syntax of an object type defines the abstract data structure
 corresponding to that object type.  The ASN.1[5] language is used for
 this purpose.  However, STD 16, RFC 1155 purposely restricts the
 ASN.1 constructs which may be used.  These restrictions are
 explicitly made for simplicity.
 The access-level of an object type defines whether it makes "protocol
 sense" to read and/or write the value of an instance of the object
 type.  (This access-level is independent of any administrative
 authorization policy.)
 The implementation-status of an object type indicates whether the
 object is mandatory, optional, obsolete, or deprecated.

2. Guidelines for implementing RFC1271 objects on a Token

  Ring network
 Wherever a MacAddress is to be used in this MIB the source routing
 bit is stripped off.  The resulting address will be consistently
 valid for all packets sent by a particular node.

2.1. Host Group

 Only Token Ring isolating errors will increment the error counter for
 a particular hostEntry.  The isolating errors are: LineErrors,
 BurstErrors, ACErrors, InternalErrors, and AbortErrors.  ACErrors
 will increment the error counter only for the nearest upstream
 neighbor of the station reporting the error.  LineErrors and
 BurstErrors will increment the error counters for the station
 reporting the error and its neighbor upstream neighbor.
 InternalErrors and AbortErrors will increment the error counter for
 the station reporting the error only.  In addition, congestionErrors
 will also be counted for each hostEntry. These errors will be
 incremented in the host entry of the station that reports the errors
 in an error report frame.
 The hostOutPkts and hostOutOctets counters shall not be incremented
 for packets with errors.

2.2. Matrix Group

 Error counters are never incremented.

2.3. Filter Group

 The following conditions make up the status bitmask for token ring
 networks:

Waldbusser [Page 3] RFC 1513 Token Ring Extensions to RMON MIB September 1993

             bit #    Error
                 3    First packet after some packets were dropped
                 4    Packet with the Frame Copied Bit set
                 5    Packet with the Address Recognized Bit set
 For the purpose of the packet match algorithm, the filters assume a
 32 byte RIF field.  Thus, when matching, the filter is compared to
 the packet starting at the AC byte of the packet, until the end of
 the RIF field; then the unused RIF bytes in the filter are skipped
 and matching proceeds from that point.  Any filter "care" bits in the
 RIF that don't correspond to bytes in the input packet will cause the
 filter to fail.

2.4. Other comments

 Because soft error report packets may be sent with assured delivery,
 some errors may be accidently reported twice on devices that perform
 the RMON function promiscuously.

3. Overview of the RMON Token Ring Extensions MIB

 The Remote Network Monitoring MIB, RFC 1271, defines a framework for
 remote monitoring functions implemented on a network probe.  That MIB
 defines objects broken down into nine functional groups.  Some of
 those functional groups, the statistics and the history groups, have
 a view of the data-link layer that is specific to the media type and
 require specific objects to be defined for each media type.  RFC 1271
 defined those specific objects necessary for Ethernet.  This MIB
 defines contains four groups that define those specific objects
 necessary for Token Ring LANs.
 In addition, this memo defines some additional monitoring functions
 specifically for Token Ring.  These are defined in the Ring Station
 Group, the Ring Station Order Group, the Ring Station Configuration
 Group, and the Source Routing Statistics Group.

3.1. The Token Ring Statistics Groups

 The Token Ring statistics groups contain current utilization and
 error statistics.  The statistics are broken down into two groups,
 the Token Ring Mac-Layer Statistics Group and the Token Ring
 Promiscuous Statistics Group.  The Token Ring Mac-Layer Statistics
 Group collects information from Mac Layer, including error reports
 for the ring and ring utilization of the Mac Layer.  The Token Ring
 Promiscuous Statistics Group collects utilization statistics from
 data packets collected promiscuously.

Waldbusser [Page 4] RFC 1513 Token Ring Extensions to RMON MIB September 1993

3.2. The Token Ring History Groups

 The Token Ring History Groups contain historical utilization and
 error statistics.  The statistics are broken down into two groups,
 the Token Ring Mac-Layer History Group and the Token Ring Promiscuous
 History Group.  The Token Ring Mac-Layer History Group collects
 information from Mac Layer, including error reports for the ring and
 ring utilization of the Mac Layer.  The Token Ring Promiscuous
 History Group collects utilization statistics from data packets
 collected promiscuously.

3.3. The Token Ring Ring Station Group

 The Token Ring Ring Station Group contains statistics and status
 information associated with each Token Ring station on the local
 ring.  In addition, this group provides status information for each
 ring being monitored.

3.4. The Token Ring Ring Station Order Group

 The Token Ring Ring Station Order Group provides the order of the
 stations on monitored rings.

3.5. The Token Ring Ring Station Config Group

 The Token Ring Ring Station Config Group manages token ring stations
 through active means.  Any station on a monitored ring may be removed
 or have configuration information downloaded from it.

3.6. The Token Ring Source Routing Group

 The Token Ring Source Routing Group contains utilization statistics
 derived from source routing information optionally present in token
 ring packets.

4. Terminology

 The 802.5 specification [7] defines the term "good frame" as a frame
 that is bounded by a valid SD and ED, is an integral number of octets
 in length, is composed of only 0 and 1 bits between the SD and the
 ED, has the FF bits of the GC field equal to 00 or 01, has a valid
 FCS, and has a minimum of 18 octets between the SD and the ED.  This
 document will use the term "good frame" in the same manner.
