1. Introduction
This document defines a Management Information Base (MIB) module for
managing multicast address allocation in a protocol-independent
manner, as well as for managing specific protocols used in allocating
multicast addresses. The protocol-independent objects in this MIB
apply to all multicast address allocation servers (MAASs) and
clients, as described in [ARCH], including those that allocate
source-specific multicast addresses for the local machine.
The protocol-specific objects in this MIB include objects related to
the Multicast Address Dynamic Client Allocation Protocol (MADCAP)
[MADCAP]. Interactions with the Multicast-scope Zone Announcement
Protocol (MZAP) [MZAP] are also noted where appropriate.
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
RFC3410 [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,
RFC2578 [RFC2578], STD 58, RFC2579 [RFC2579] and STD 58, RFC2580
[RFC2580].
3. Overview
The purpose of this MIB module is to provide the ability to configure
and monitor the status of multicast address allocation within the
local domain.
Some important monitoring questions which can be answered by this MIB
module include:
o How full is scope X?
o Who's using up the space?
o Who allocated a given address A?
o Are requests being met?
This MIB module is divided into two primary sections:
o Protocol-independent objects relevant to all multicast address
allocation servers and clients.
o Protocol-specific objects related to the MADCAP client-server
protocol.
3.1. Protocol-independent objects
The protocol-independent objects consist of one "capabilities" scalar
and five tables. The tables are:
o The Scope Table contains information on the multicast scopes
known to a multicast address allocation server. This table
allows configuring scopes, and viewing what scopes are known to
the local system after being configured elsewhere.
o The Scope Name Table contains the names of the multicast
scopes. This table logically extends the Scope Table with the
list of scope names in various languages for each scope.
o The Allocation Range Table contains the address ranges out of
which the device may allocate addresses. It also allows
answering the questions "How full is scope X?" and "Are
requests being met?"
o The Request Table contains the requests for address
allocations, and allows answering the question "Who's using up
the space?"
o The Address Table contains the blocks of addresses which have
been allocated, and together with the Request Table, allows
answering the question "Who allocated a given address A?"
3.2. Protocol-specific objects
The MADCAP objects consist of a group of (scalar) configuration
parameters, and a group of (scalar) statistics.

allocations with a future start time are supported. The

for a waiting state where the client may check back at a

5. IANA Considerations
The IANAscopeSource and IANAmallocRangeSource textual conventions are
imported from the IANA-MALLOC-MIB. The purpose of defining these
textual conventions in a separate MIB module is to allow additional
values to be defined without having to issue a new version of this
document. The Internet Assigned Numbers Authority (IANA) is
responsible for the assignment of all Internet numbers, including
various SNMP-related numbers; it will administer the values
associated with these textual conventions.
The rules for additions or changes to the IANA-MALLOC-MIB are
outlined in the DESCRIPTION clause associated with its MODULE-
IDENTITY statement.
The current versions of the IANA-MALLOC-MIB can be accessed from the
IANA home page at: "http://www.iana.org/".
6. 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:
mallocScopeTable,mallocAllocRangeTable:
Unauthorized modifications to these tables can result in denial of
service by not being able to allocate and use multicast addresses,
allocating too many addresses, allocating addresses that other
organizations are already using, or causing applications to use a
hop limit that results in extra bandwidth usage.
mallocScopeNameTable:
Unauthorized modifications to this table can result in incorrect
or misleading scope names being presented to users, resulting in
potentially using the wrong scope for application data.
madcapConfigExtraAllocationTime,madcapConfigOfferHold:
Unauthorized modifications to these objects can result in
reservations lasting too long, potentially resulting in denial of
service if allocation ranges are small.
madcapConfigNoResponseDelay:
Unauthorized modifications can result in a client not being able
to allocate multicast addresses.
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 GET and/or NOTIFY access to these objects and possibly to
encrypt the values of these objects when sending them over the
network via SNMP. These are the tables and objects and their
sensitivity/vulnerability:
mallocRequestLeaseIdentifier:
If address allocation servers are configured to allow renewal or
release purely on the basis of knowledge of the Lease Identifier,
then unauthorized read access to mallocRequestLeaseIdentifier can
be used in a denial-of-service attack.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
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 for only those
principals (users) with legitimate rights to have access to GET or
SET (change/create/delete) objects.
