Internet-Draft ANCP MIB February 2008
1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols. In particular it defines
objects for managing network access servers as described in [ANCPFW]
that are using the Access Node Control Protocol defined in [ANCPPR].
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
3. Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
4. Overview
In [ANCPFW], the framework for the Access Node Control Protocol
(ANCP) is described. It defines 2 network entities, the Access Node
(AN) and the Network Access Server (NAS), between which ANCP sessions
are established. The detailed protocol specification of ANCP is
described in [ANCPPR]. This document specifies a MIB module for a
NAS that supports ANCP.
Note: the current MIB definition is specific for [ANCPPR]. If
[ANCPPR] gets updated later, then the MIB definition in this document
will also follow these changes.
5. Structure of the MIB Module
De Cnodder Expires August 17, 2008 [Page 3]
Internet-Draft ANCP MIB February 2008
5.1. Textual Conventions
No new textual conventions are defined in this MIB module. Note that
2 textual conventions are imported from ANCP-TC-MIB.
5.2. The ANCP-NAS MIB module Subtree
The ANCP MIB module for network access servers is put under ancpMIB.
ancpMIB in defined in [MIBAN] where a MIB module with textual
conventions for ANCP is defined, and also a MIB module for access
nodes. We have the following definitions in [MIBAN] and in this
document:
ancpTcMIB ::= { ancpMIB 1}
ancpAnMIB ::= { ancpMIB 2}
ancpNasMIB ::= { ancpMIB 3}
ancpMIB is put under mib-2, and its OID is assigned by IANA in
[MIBAN].
5.3. The Notifications Subtree
Notifications are defined to inform the management station about
state changes of ANCP sessions, whenever an ANCP session changes
state. Two notifications are defined for this purpose. The
notification ancpNasSessionUp is to inform the management station
when the session comes up, and the notification ancpNasSessionDown is
to inform when the ANCP session is down again after it was up before.
Attributes are introduced to enable and disable the generation of
these notifications for ANCP sessions. To avoid congestion towards
the management station, the NAS should limit the number of
notifications sent in a specific time period. If the number of ANCP
is sessions is expected to be large, it is recommended to disable the
generation of notifications, or to enable them on only a set of
sessions.
5.4. The Table Structures
The ANCP MIB module for the NAS has 3 tables. The tables are the
following:
o ancpNasSessionConfigTable
This table specifies a number of attributes to be used for all
sessions in a particular partition. No indiviual sessions are
configured such that when new ANs are added to the network, no
extra configuration is needed on the NAS, except if a new
De Cnodder Expires August 17, 2008 [Page 4]
Internet-Draft ANCP MIB February 2008
partition is added to the ANs. The row with zero partition ID
specifies the attributes of the sessions that belong to ANs that
do not use partitions. The AN initiates the establishement of the
transport session (e.g., TCP session), and after the
establishement of the transport session, the AN and/or NAS can
start the establishement of the ANCP session. If the NAS can
determine to which partition the session belongs after the
transport session is up, the NAS can initiate the establishement
of the ANCP session, otherwise, only the AN can initiate it.
o ancpNasCurrentSessionTable
This table is a read-only table and shows the operational state of
a particular ANCP session. The row is created when the NAS has
information about a particular session, and is deleted when there
is no information available anymore.
o ancpNasAciInfoTable
This table is a read-only table and shows all the information
about a particular Access Circuit Identifier (ACI) that the AN has
advertised to the NAS in a PORT UP message. Each time a PORT UP
message is received with a new ACI, a new row is created. When
the NAS has no information anymore about an ACI, the row is
deleted.
Five groups are defined:
o ancpNasConfigGroup,
This group contains all objects of the ancpNasSessionConfigTable
in which the objects for ANCP sessions are configured.
o ancpNasCurrentGroup,
This group contains all objects of the ancpNasCurrentSessionTable
where the operational state and other information of ANCP sessions
are shown.
o ancpNasAciGroup
This group contains objects that contain basic information about a
particular ACI.
o ancpNasAciOptionalGroup
This group contains objects that contain very detailed information
about a particular ACI, and complements ancpNasAciGroup.
De Cnodder Expires August 17, 2008 [Page 5]
Internet-Draft ANCP MIB February 2008
o ancpNasNotificationsGroup
This group contains the notifications that indicate state changes
of ANCP sessions.
6. Relationship to Other MIB Modules
6.1. Relationship to the ANCP-NAS MIB module
The ANCP-NAS-MIB module has no relationship with any other MIB
module, otherwise than those MIB modules that are needed for IMPORTS.
6.2. MIB modules required for IMPORTS
The ANCP MIB module for network access servers requires following MIB
modules for IMPORTS:
o SNMPv2-SMI defined in [RFC2578]
o RMON2-MIB defined in [RFC4502]
o INET-ADDRESS-MIB defined in [RFC4001]
o SNMPv2-CONF defined in [RFC2580]
o GSMP-MIB defined in [RFC3295]
o SNMPv2-TC defined in [RFC2579]
o ANCP-TC-MIB defined in [MIBAN]

8. Security Considerations
There are a number of management objects defined in this MIB module
with 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. These are the tables and objects and their
sensitivity/vulnerability:
ancpNasSessionConfigTable is the only table with read-write and/or
read-create objects, which are:
o ancpNasSessionConfigRowStatus
o ancpNasSessionConfigGsmpVersion
o ancpNasSessionConfigGsmpSubVersion
o ancpNasSessionConfigEncapsulationType

Unauthorized changes to ancpNasSessionConfigRowStatus can result in
unauthorized changes of some objects in ancpNasSessionConfigTable.
It could also result in tearing down many ANCP sessions, and re-
establishing them with wrong parameters.
Unauthorized changes to ancpNasSessionConfigGsmpVersion or
ancpNasSessionConfigGsmpSubVersion could have an adverse operational
effect by limiting the GSMP version to be used in the context of the
sessions corresponding to this row or enabling a GSMP version number
that is actually unsupported by the network access server
Unauthorized changes to ancpNasSessionConfigEncapsulationType could
have an adverse operational effect by configuring the sessions to use
an undesired or even unsupported protocol.

Unauthorized changes to ancpNasSessionConfigCapabilities could have
an adverse operational effect by disabling certain ANCP capabilities
that the operator assumed that are enabled, or enable a capability
that the operator would not like to activate.
Unauthorized changes to ancpNasSessionConfigAliveTimer could have an
adverse operational effect by increasing the frequency of adjacency
protocol messages generated by the access node and leading to an
overload of such messages. Decreasing the frequency of such messages
may harm the synchronization between the access node and the NAS.
Unauthorized changes to ancpNasSessionConfigAncpRetryTimer could have
an adverse operational effect by increasing the frequency of
transport connection setup attempts initiated by the network access
server or even unexpectedly enabling the network access server to
initiate the transport connection setup when that supposed to be
disabled. Alternatively, when the operator basically planned
transport connection setup attempts by the network access server
unauthorized changes to the attribute may cause unexpected low
frequency of such attempts or unexpectedly disable those attempts.
Unauthorized changes to ancpNasSessionConfigNasName could confuse the
AN. This may also override the operator's will to allow/avoid the
network access server to autonomously determine its name.
Unauthorized changes to ancpNasSessionConfigEncapPortNumber could
specify a wrong transport protocol port number for the sessions,
resulting in the session not being established.
Unauthorized changes to ancpNasSessionConfigNotifyDnEnable and
ancpNasSessionConfigNotifyUpEnable could result in notifications not
being generated while they were expected to be generated, and could
result in generating too many undesirable notifications. In the
latter case, since the network access server is also supposed to rate
limit the notifications to the SNMP manager, this could result in
desired notifications being delayed or lost.
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. These are the tables and objects and their
sensitivity/vulnerability:

Access to these objects would allow an intruder to obtain

SNMP versions prior to SNMPv3 did not include adequate security.
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 module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module 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.

No actions from IANA are required.
