networks.

The Remote Network Monitoring MIB, RFC2819, 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.  RFC2819
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 SNMP Management Framework

   The SNMP Management Framework presently consists of five
   major components:

    o   An overall architecture, described in RFC 2571 [1].

    o   Mechanisms for describing and naming objects and
        events for the purpose of management. The first
        version of this Structure of Management Information
        (SMI) is called SMIv1 and described in STD 16, RFC
        1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
        second version, called SMIv2, is described in STD 58,
        RFC 2578 [5], RFC 2579 [6] and RFC 2580 [7].

    o   Message protocols for transferring management
        information. The first version of the SNMP message
        protocol is called SNMPv1 and described in STD 15, RFC
        1157 [8]. A second version of the SNMP message
        protocol, which is not an Internet standards track
        protocol, is called SNMPv2c and described in RFC 1901
        [9] and RFC 1906 [10]. The third version of the
        message protocol is called SNMPv3 and described in RFC
        1906 [10], RFC 2572 [11] and RFC 2574 [12].

Internet Draft Token Ring Extensions to RMON MIB March 2, 2001


    o   Protocol operations for accessing management
        information. The first set of protocol operations and
        associated PDU formats is described in STD 15, RFC
        1157 [8]. A second set of protocol operations and
        associated PDU formats is described in RFC 1905 [13].

    o   A set of fundamental applications described in RFC
        2573 [14] and the view-based access control mechanism
        described in RFC 2575 [15].

   A more detailed introduction to the current SNMP Management
   Framework can be found in RFC 2570 [18].

   Managed objects are accessed via a virtual information
   store, termed the Management Information Base or MIB.
   Objects in the MIB are defined using the mechanisms defined
   in the SMI.

   This memo specifies a MIB module that is compliant to the
   SMIv2. A MIB conforming to the SMIv1 can be produced
   through the appropriate translations. The resulting
   translated MIB must be semantically equivalent, except
   where objects or events are omitted because no translation
   is possible (use of Counter64). Some machine readable
   information in SMIv2 will be converted into textual
   descriptions in SMIv1 during the translation process.
   However, this loss of machine readable information is not
   considered to change the semantics of the MIB.

2.  Guidelines for implementing RFC2819 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 nearest
upstream neighbor.  InternalErrors and AbortErrors will
increment the error counter for the station reporting the
error only.  In addition to these isolating errors,
congestionErrors 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 because the monitor cannot
receive all error packets with which to update these
statistics.


2.2.  Matrix Group

Error counters are never incremented because the monitor
cannot recieve all error packets with which to update these
counters.


2.3.  Filter Group

The following conditions make up the status bitmask for token
ring networks:
     bit #    Status
         3    First packet after some packets were dropped
         4    Packet with the Frame Copied Bit set
         5    Packet with the Address Recognized Bit set

Internet Draft Token Ring Extensions to RMON MIB March 2, 2001


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, RFC2819, 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.  RFC2819
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.

Internet Draft Token Ring Extensions to RMON MIB March 2, 2001


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 [20] 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.

6.  Security Considerations

In order to implement this MIB, a probe must capture all
packets on the locally-attached network, including packets
between third parties.  These packets are analyzed to collect
network addresses, protocol usage information, and
conversation statistics. Data of this nature may be considered
sensitive in some environments. In such environments the
administrator may wish to restrict SNMP access to the probe.

This MIB also includes the ability to remove a station from a
ring. Unauthorized use of this feature could constitute a
denial of service attack. The administrator may wish to
restrict access to the MIB object
(ringStationConfigControlRemove) that implements this ability.

There are a number of management objects defined in this MIB
that have a MAX-ACCESS clause of read-write and/or read-
create.  Such objects may be considered sensitive or
vulnerable in some network environments.  The support for SET
operations in a non-secure environment without proper
protection can have a negative effect on network operations.

SNMPv1 by itself is not a secure environment.  Even if the
network itself is secure (for example by using IPSec), even
then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the
objects in this MIB.

It is recommended that the implementors consider the security
features as provided by the SNMPv3 framework.  Specifically,
the use of the User-based Security Model RFC 2574 [12] and the
View-based Access Control Model RFC 2575 [15] is recommended.

It is then a customer/user responsibility to ensure that the
SNMP entity giving access to an instance of this MIB, is
properly configured to give access to the objects only to
those principals (users) that have legitimate rights to indeed
GET or SET (change/create/delete) them.
