Dial Control Management Information Base using SMIv2
Status of this Memo
This document 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" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects used for managing demand
access circuits, including ISDN.
This document specifies a MIB module in a manner that is compliant to
the SNMPv2 SMI. The set of objects is consistent with the SNMP
framework and existing SNMP standards.
This document is a product of the ISDN MIB working group within the
Internet Engineering Task Force. Comments are solicited and should
be addressed to the working group's mailing list at isdn-
mib@cisco.com and/or the author.

1. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework presently consists of three
major components. They are:
o the SMI, described in RFC 1902 [1] - the mechanisms used for
describing and naming objects for the purpose of management.
o the MIB-II, STD 17, RFC 1213 [2] - the core set of managed
objects for the Internet suite of protocols.
o the protocol, STD 15, RFC 1157 [3] and/or RFC 1905 [4], -
the protocol for accessing managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
1.1. Object Definitions
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)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. 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 descriptor, to refer to the
object type.
2. Overview
2.1. Structure of MIB
Managing demand access circuits requires the following groups of
information:
o General configuration information.
o Information to describe peer configuration and peer statistics.
In this respect, peer configuration means information on how to
connect to peers on outgoing calls, how to identify peers on
incoming calls, and other call related configuration
information.
o Information to store active call information.
Roeck Standards Track [Page 2]
RFC 2128 Dial Control MIB March 1997
o Information to retain call history.
The MIB, therefore, is structured into four groups.
o The dialCtlConfiguration group is used to specify general
configuration information.
o The dialCtlPeer group is used to describe peer configuration
and peer statistics.
o The callActive group is used to store active call information.
o The callHistory group is used to store call history information.
These calls could be circuit switched or they could be virtual
circuits. History of each and every call is stored, of successful
calls as well as unsuccessful and rejected calls. An entry will
be created when a call is cleared.
2.2. Relationship to the Interfaces MIB
This section clarifies the relationship of this MIB to the Interfaces
MIB [8]. Several areas of correlation are addressed in the following
subsections. The implementor is referred to the Interfaces MIB
document in order to understand the general intent of these areas.
2.2.1. Layering Model and Virtual Circuits
On an occasional access channel, there are a number of peer systems
that are permitted to call or be called, all of which need to be
treated as active from a routing viewpoint, but most of which have no
call in progress at any given time.
On dialup interfaces, this is further complicated by the fact that
calls to a given peer float from channel to channel. One cannot
definitively say "I call this peer on that interface." It is
necessary, therefore, to provide a mapping algorithm between the
low-level interfaces, and the various logical interfaces supporting
the peers. This is solved by creating a logical interface (ifEntry)
for each peer and a logical interface (ifEntry) for each low-level
interface. These are then correlated using the ifStackTable.
The low-level interfaces are either physical interfaces, e.g. modem
interfaces, or logical interfaces, e.g. ISDN B channels, which then
in turn are layered on top of physical ISDN interfaces.
Roeck Standards Track [Page 3]
RFC 2128 Dial Control MIB March 1997
The model, therefore, looks something like this, taking ISDN as an
example:
+-------------------------------------------------------+
| Network Layer Protocol |
+------+ +-------+ +-------+ +-------+ +-------+ +------+
| | | | | | | | | | <== appears active
+-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+
| PPP | | PPP | | F/R | | PPP | | F/R |

|Peer1| |Peer2| |switch |Peer3| |switch shadow PeerEntry
| | | | | A | | | | B |
+-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+
| | | | <== some actually are
+--+ +--+ +--+ +--+ +--+ +--+ +--+ +--+ +--+ +--+

+--+ +--+ +--+ +--+ +--+ +--+ +--+ +--+ +--+ +--+
| | | | | | | | | |
+------+ +-------+ +-------+ +-------+ +-------+ +------+
| Basic/Primary Rate Interface |
+-------------------------------------------------------+
Mapping of IP interfaces to Called Peers to B Channels
IfEntries are maintained for each peer.
In this model, each peer is required to have an associated
encapsulation layer interface. This interface can be of any kind,
e.g. PPP or LAPB.
In order to specify the network address for a given peer, one would
then usually add a routing/forwarding table entry, pointing to the
encapsulation layer interface through which this peer can be reached.
2.2.2. ifTestTable
The ifTestTable usage is defined in the MIBs defining the
encapsulation below the network layer. For example, if PPP
encapsulation is being used, the ifTestTable is defined by PPP.
2.2.3. ifRcvAddressTable
The ifRcvAddressTable usage is defined in the MIBs defining the
encapsulation below the network layer. For example, if PPP
encapsulation is being used, the ifRcvAddressTable is defined by PPP.
Roeck Standards Track [Page 4]
RFC 2128 Dial Control MIB March 1997
2.2.3.1. ifEntry for a single peer
IfEntries are defined in the MIBs defining the encapsulation below
the network layer. For example, if PPP encapsulation is being used,
the ifEntry is defined by PPP.
ifEntries will never be created by the Dial Control MIB. The Dial
Control MIB always depends on some other ifIndex of some set of
ifTypes. That is, to create an entry in the Dial Control MIB, the
base ifEntry must already have been created through some other
mechanism.
The Dial Control entry does have its own RowStatus, permitting the
Dial Control supplementary information to come and go, but not
otherwise disturbing the ifIndex to which it is attached. If in a
given implementation the two are tightly bound, deleting the ifEntry
may have the side effect of deleting the Dial Control entry.
2.3. Multilink and backup line support
In order to support multilink and backup procedures, there may be
several entries for a single peer in the dialCtlPeerCfgTable.
A single peer is identified using the dialCtlPeerCfgId object of the
dialCtlPeerCfgTable. There may be several entries in
dialCtlPeerCfgTable with the same value of dialCtlPeerCfgId, but
different ifIndex values. Each of those entries will then describe a
possible connection to the same peer. Such entries can then be used
to handle multilink as well as backup procedures, e.g. by bundling
the attached ifEntries using PPP multilink.
2.4. Support for generic peers
Generic peers can for example be supported by permitting wild-card
characters (e.g., '?' or '*') in dialCtlPeerCfgAnswerAddress. A
number to be accepted could then be defined as partly (e.g., '*1234')
or entirely generic (e.g., '*').
A detailed specification of such a functionality is outside the scope
of this document.
However, the implementor should be aware that supporting generic
peers may cause a security hole. The user would not know where a
call is from, which could potentially allow unauthorized access.

6. Security Considerations
Information in this MIB may be used by upper protocol layers for
security purpose.
The implementor should be aware that supporting generic peers as
described in section 3.4 may cause a security hole. The user would
not know where a call is from, which could potentially allow
unauthorized access if there is no other authentication scheme, e.g.
PPP authentication, available.
