Token Ring Extensions to the Remote Network Monitoring MIB
Status of this Memo
This RFCspecifies 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, RFC1271, 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. RFC1271
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, RFC1155 [1] which defines the SMI, the mechanisms used
for describing and naming objects for the purpose of management.
STD 16, RFC1212 [2] defines a more concise description mechanism,
which is wholly consistent with the SMI.
STD 17, RFC1213 [3] which defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
STD 15, RFC1157 [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, RFC1212"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.
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, RFC1155 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:
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, RFC1271, 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. RFC1271
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.
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.
