1. Status of this Memo
This document is a draft private extension to the SNMP MIB.
Distribution of this memo is unlimited. Please send
comments to the editor.
2. Abstract
This memo defines a private extension to the Management
Information Base (MIB) for use with network management
protocols in TCP/IP-based internets. In particular, it
defines objects that Local Exchange Carriers (LECs) and
Interexchange Carriers (ICs) can use to manage intercarrier
SMDS (i.e., when multiple carriers are involved in providing
SMDS to end-users).
This memo does not specify a standard for the Internet
community.

3. The Network Management Framework
The Internet-standard Network Management Framework consists
of three components. They are:
RFC 1155 [1] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
RFC 1212 [2] defines a more concise description mechanism,
which is wholly consistent with the SMI.
RFC 1156 [3] which defines MIB-I, the core set of managed
objects for the Internet suite of protocols. RFC 1213 [4],
defines MIB-II, an evolution of MIB-I based on
implementation experience and new operational requirements.
RFC 1157 [5] 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.
S. Hansen (editor) [Page 2]

4. Objects
Managed objects are accessed via a virtual information
store, termed the Management Information Base or MIB.
Objects in the MIB are defined using the subset of Abstract
Syntax Notation One (ASN.1) [6] defined in the SMI. In
particular, each object has a name, a syntax, and an
encoding. 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
language is used for this purpose. However, the SMI [1]
purposely restricts the ASN.1 constructs which may be used.
These restrictions are explicitly made for simplicity.
The encoding of an object type is simply how that object
type is represented using the object type's syntax.
Implicitly tied to the notion of an object type's syntax and
encoding is how the object type is represented when being
transmitted on the network. The SMI specifies the use of
the basic encoding rules of ASN.1 [7], subject to the
additional requirements imposed by the SNMP.
4.1. Format of Definitions
Section 6 contains the specification of all object types
contained in this MIB module. The object types are defined
using the conventions defined in the SMI, as amended by the
extensions specified in RFC1212 [2].

5. Overview
This section provides an overview and background
of how to use this MIB module and other potential MIB modules
when managing intercarrier SMDS. Intercarrier SMDS
refers to two or more carriers involved in providing
an end-to-end SMDS service [8].
The following diagram shows the MIB stack that
could be followed for managing intercarrier SMDS. This is only
an example and not meant to be inclusive.
+----------------------------------------------------------+
+ MIB | Intercarrier SMDS | SMDS Subscription | T +
+ II |---------------------|--------------------| C +
+ | DS3 | | A +
+----------------------------------------------------------+
SCOPE OF MIB MODULE:
The intercarrier SMDS MIB module will only manage the SMDS
portion of the network related to carrier interconnections.
SMDS Exchange Access Operations Management (XA-OM) and
Exchange Carrier Operations Management (ECOM) also rely on
the SMDS Subscription MIB module [9], the DS3 MIB module
[10], and TCA MIB module [11].
This MIB module will NOT be implemented on User Equipment.
The SMDS SNMP MIB module for XA-OM and ECOM is an SNMPv1
MIB. It provides read-only information that allows an IC or
neighboring LEC to obtain performance monitoring, fault, and
configuration information about: 1) the ICIs that
interconnect its network with a LEC's network to provide
intercarrier SMDS and 2) information pertaining to the
overall management of the end-to-end SMDS service. By using
this and other related MIB modules, a carrier's (i.e., IC's
or neighboring LEC's) NM application can monitor ICIs and
service aspects of intercarrier SMDS. Internal aspects of
the network (e.g., switching elements, line cards, and
network routing tables) are outside the scope of this MIB
module. The carrier's NM application will be able to access
the SNMP proxy-agent within a LEC's SMDS network using SNMP
over UDP over IP with IP encapsulated in SMDS according to
RFC1209 [12]. The initial implementation of the MIB module
S. Hansen (editor) [Page 4]
Bellcore Intercarrier SMDS MIB June 1994
is based on SNMPv1. The service capabilities include
retrieving information and receiving TRAPs. This MIB module
will make use of MIB II whenever possible. Since this MIB
module will only manage the SMDS portion of the network, the
scope of this MIB module does not include managed objects
that: 1) monitor the physical layer, 2) support Threshold
Crossing Alerts specified for SMDS XA-OM and ECOM, and 3)
associate an SMDS individual address with a Subscriber-
Network Interface (SNI). These objects have already been
defined in the DS3, TCA, and SMDS Subscription MIB modules.
5.1. Apply MIB II to Intercarrier SMDS
Use the System Group to apply to the SNMP proxy-agent, since
the proxy-agent may be monitoring many SMDS devices in one
network. System Group applies to only one system. This
group is not instantiated.
sysDescr: ASCII string describing the SNMP proxy-agent.
Can be up to 255 characters long. This field is
generally used to indicate the network providers
identification and type of service offered.
sysObjectID: Unique Object Identifier (OID) for
the SNMP proxy-agent.
sysUpTime: Clock in the SNMP proxy-agent; TimeTicks
in 1/100s of a second. Elapsed type since
the proxy-agent came on line.
sysContact: Contact for the SNMP proxy-agent.
ASCII string of up to 255 characters.
sysName: Domain name of the SNMP proxy-agent, for example,
acme.com
sysLocation: Location of the SNMP proxy-agent.
ASCII string of up to 255 characters.
sysServices: Services of the managed device. The value "2"
which implies that the SMDS network is providing
a subnetwork level service is recommended.
This memo specifies how the Interfaces General Group
S. Hansen (editor) [Page 5]
Bellcore Intercarrier SMDS MIB June 1994
(ifGeneralGroup) defined in MIB II shall be used for the
management of intercarrier SMDS based interfaces. This memo
assumes the interpretation of the ' interfaces' group to be
in accordance with [13]: "... the 'interfaces' group which
defines a generic set of managed objects such that any
network interface can be managed in an interface-independent
manner through these objects." Thus, the 'interfaces' group
allows the following intercarrier SMDS-based interfaces to
be represented as table entries:
SMDS interfaces in the SMDS equipment (e.g., switches,
routers, or networks) - This information is
predominantly related to the ICI; however, there are
several Subscriber-Network Interface (SNI) related
objects.
Except for the DS3 MIB module, any counts related to the ICI
or SNI for SMDS XA-OM and ECOM are specified in this MIB
module. To interrelate the ifEntries properly, the
Interfaces Stack Group defined in [13] shall be supported.
Carriers should be able to access the
following objects in the ifGeneralGroup when they
apply to SNI sublayers:
- ifIndex,
- ifDescr,
- ifType, and
- ifOperStatus.
The manner in which these objects are supported for the SNI
sublayers is described in the SMDS Interface Protocol (SIP) MIB
module [14] and Bellcore Technical Reference
TR-TSV-001062 [15].
The following figure illustrates how the ICI has been modeled
using 2 sublayers:
+------------+
| ICIP |
+------------+
| DS3 |
+------------+
The ICIP sublayer consists of ICIP Level 3, Level 2, and
Physical Layer Convergence Procedure (PLCP).
S. Hansen (editor) [Page 6]
Bellcore Intercarrier SMDS MIB June 1994
Some specific interpretations of ifGeneralGroup for intercarrier
SMDS follow.
Object Use for Each Sublayer of the ICI
====== ================================
ifIndex Each sublayer of the ICI has an ifIndex.
ifDescr ASCII string describing the ICI sublayers.
Can be up to 255 characters long.
ifType The value to be allocated for ICIP sublayer is
"52" (smdsIcip). The value to be allocated
for the DS3 sublayer of the ICI is "30"
(i.e., DS3).
ifSpeed Peak bandwidth in bits per second available
for use by the ICI sublayer. The value of
this object is 34 Mbps for the ICIP
sublayer and 45 Mbps for the DS3
sublayer.
ifPhysAddress A zero-length string is used for
the ICIP sublayer. For the DS3 sublayer,
the value of this object is the DS3
circuit identifier.
ifAdminStatus Supports read-only access. The value of this
object for both ICI sublayers is the desired
administrative status of the DS3 sublayer.
ifOperStatus The value of this object for both ICI
sublayers is the current operational status
of the DS3 sublayer.
ifLastChange The value of this object for both ICI
sublayers is the elapsed time since the last
re-initialization of the DS3
sublayer.
ifLinkUpDownTrapEnable This object should be set to enabled
(1) for DS3 sublayer and disabled (2) for
the ICIP sublayer.
ifConnectorPresent This object should be set to true (1) for
the DS3 sublayer and false (2) for the ICIP
S. Hansen (editor) [Page 7]
Bellcore Intercarrier SMDS MIB June 1994
sublayer.
ifHighSpeed An estimate of the current bandwidth available
for use by both ICI sublayers (e.g., 34 Mbps
for the ICIP sublayer).
ifName This object should be set to a zero length
string for both ICI sublayers.
If an object in the ifGeneralGroup is not supported, the
SNMP proxy agent should return the value "noSuchName"
following SNMPv1 procedures.
5.2. Apply the SMDS Subscription MIB Module to Intercarrier
SMDS
SMDS XA-OM and ECOM makes use of one group from the
SMDS Subscription MIB Module: SMDS Address Table Group.
Access to this group will enable a carrier to associate an
SMDS address with an ifIndex [9]. As such, the SMDS Address
Table Group is mandatory.
5.3. Apply the TCA MIB Module to Intercarrier SMDS
The TCA MIB module should be used for the Threshold Crossing Alerts
specified for SMDS XA-OM and ECOM [11]. This MIB module
contains objects associated with TCAs. By accessing objects in
this MIB module, carriers can determine when the last threshold
crossing associated with a given count occurred, the number of
times a given threshold has been crossed since the agent was
initialized, and whether a threshold crossing results in a trap
message. This MIB module is mandatory.
5.4. Apply the DS3 MIB Module to Intercarrier SMDS
The DS3/E3 MIB (RFC1407) should be used to manage DS3
sublayer of an SMDS ICI [10]. The ifIndex value from the
ifGeneralGroup should be used to identify the DS3 sublayer for a
given ICI. For an SMDS ICI:
ifIndex = dsx3LineIndex = dsx3IfIndex.
S. Hansen (editor) [Page 8]
Bellcore Intercarrier SMDS MIB June 1994
Mandatory groups for this MIB module are:
dsx3ConfigTable,
dsx3CurrentTable, and
dsx3IntervalTable.
Note that for the IntervalTable, only eight intervals are supported
for SMDS XA-OM and ECOM.
