Introduction + + 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 objects used for managing the Internet + Group Management Protocol (IGMP) version 1 [RFC1112], version 2 + [RFC2236], or version 3 [RFC3376] and the Multicast Listener + Discovery (MLD) protocol version 1 [RFC2710] or version 2 [RFC3810]. + Both protocols provide multicast membership discovery capability. + IGMP pertains to IP version 4 clients, and MLD to IP version 6 + clients. This version of the MIB obsoletes both RFC 2933 [RFC2933] + and RFC 3019 [RFC3019], incorporating a generic interface for both + IGMP and MLD implementations and incorporating changes to enable + "source filtering" in multicast clients. The MIB encompasses both + router and host nodes with relevant management objects defined for + each. + +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]. + + + + + +Chesterfield & Haberman Standards Track [Page 2] + +RFC 5519 MGMD MIB April 2009 + + +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 RFC 2119 [RFC2119]. + +4. Overview + + This Multicast Group Membership Discovery (MGMD) MIB module contains + eight tables: + + 1. the MGMD Host Interface Table, which contains one row for each + interface on which IGMP or MLD is enabled on a host, + + 2. the MGMD Router Interface Table, which contains one row for each + interface on which MGMD is enabled on a router, + + 3. the MGMD Host Cache Table, which contains one row for each IP + multicast group for which there are members on a particular + interface on a host, + + 4. the MGMD Router Cache Table, which contains one row for each IP + multicast group for which there are members on a particular + interface on a router, + + 5. the reverse MGMD Host Table, which contains one row for each + interface for which there are active multicast groups on a host, + + 6. the reverse MGMD Router Table, which contains one row for each + interface for which there are active multicast groups on a + router, + + 7. the MGMD HostSrcList Table, which contains one row for each entry + in the source filter record for an interface and multicast group + pair on a host, and + + 8. the MGMD RouterSrcList Table, which contains one row for each + entry in the source filter record for an interface and multicast + group pair on a router. + + All tables are intended for EITHER router OR host functionality as + indicated by the name and corresponding description, although it is + anticipated that there will be scenarios where both terms might apply + to a device, e.g., a router that joins a multicast group also as a + host for measurement purposes. The source list tables provide an + extension to the cache tables to indicate the source-specific + + + + + +Chesterfield & Haberman Standards Track [Page 3] + +RFC 5519 MGMD MIB April 2009 + + + includes or excludes associated with each IP multicast group on each + specific interface. This functionality is only supported in IGMPv3- + and MLDv2-capable nodes. + + Incorporated within the MGMD MIB tables are objects for the + management of IGMP and MLD proxy devices as described in RFC 4605 + [RFC4605]. Proxy devices can be used in simple topologies where it + is not necessary to run a full multicast routing protocol. A proxy + device can make forwarding decisions based on IGMP or MLD group + membership activity. + + The MIB references InterfaceIndex and InterfaceIndexOrZero objects as + defined in RFC 2863 [RFC2863], the MIB that describes generic objects + for network interface sub-layers. + + Extensive references to the InetAddress and InetAddressType objects + are made as defined in RFC 4001 [RFC4001]. + +5.

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: + + o The mgmdRouterInterfaceTable provides read-create access to 2 + values: the mgmdRouterInterfaceStatus and the + mgmdRouterInterfaceQueryInterval. The mgmdRouterInterfaceStatus + presents a remote user with the ability to enable or disable + multicast support on a given router interface, and therefore + presents a significant denial-of-service vulnerability. The + mgmdRouterInterfaceQueryInterval controls the frequency with which + host-query packets are sent, providing less of a vulnerability, + but still requiring secure access control. + + o The mgmdRouterCacheTable also provides access to read-create + objects. The mgmdRouterInterfaceVersion controls the protocol + conformance of an interface, and is therefore a potential denial- + of-service vulnerability. The + mgmdRouterInterfaceQueryMaxResponseTime, the + mgmdRouterInterfaceRobustness, and the + mgmdRouterInterfaceLastMemberQueryInterval are all tuning + parameters to control the characteristic of the host-query + packets. Compromise of these objects can potentially be + disruptive to local multicast communication. + + o The mgmdHostInterfaceTable provides a read-create object, the + mgmdHostInterfaceVersion3Robustness, which controls the robustness + of the interface to packet loss. Disabling robustness in the face + of packet loss could cause denial of service to hosts; however, in + general this presents a low risk. + + + + +Chesterfield & Haberman Standards Track [Page 38] + +RFC 5519 MGMD MIB April 2009 + + + 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. + +7. IANA Considerations + + This MIB introduces a new term to refer to two existing multicast + protocols: Multicast Group Membership Discovery. It encompasses both + the IPv4 Multicast discovery protocol, IGMP, and the IPv6 Multicast + discovery protocol, MLD, as defined in RFCs 2933 [RFC2933] and 3019 + [RFC3019], respectively. + + The MIB module in this document uses the following IANA-assigned + OBJECT IDENTIFIER value recorded in the SMI Numbers registry: + + Descriptor OBJECT IDENTIFIER value + ---------- ----------------------- + mgmdStdMIB { mib-2 185 } + +8.
