1. 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 notification objects used for managing
notifications of 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 for IP version 6 clients.
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", "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) Notification MIB
module contains three notifications that can be generated by the
MGMD protocols:
1. A mgmdWrongVersion trap is sent when a general query whose IGMP
or MLD version does not match the equivalent
mgmdRouterInterfaceVersion.
2. A mgmdInterfaceJoins trap is sent when a group membership is
added on a interface
3. A mgmdGroupsExceed trap is sent when the number of groups of
which the host is a member exceeds threshold value.
4. A mgmdInterfaceLastMemberLeave trap is sent when the last member
of group leaves on interface.

DESCRIPTION
"The MIB module for MGMD Protocol Notofication management.
A new version of MGMD notification.

REVISION "201510180000Z" - October 18, 2015
DESCRIPTION
"This MIB introduces a new RFC."
::= { mib-2 xxx }
mgmdNotificationObjects OBJECT IDENTIFIER ::= { mgmdNotificationMIB 1 }
mgmdNotifications OBJECT IDENTIFIER ::= { mgmdNotificationMIB 2 }
mgmdInterfaceVersionReceived OBJECT-TYPE
SYNTAX Unsigned32 (1..3)
MAX-Access read-only
DESCRIPTION "The MGMD version received on an interface."
::= { mgmdNotificationObjects 1 }
mgmdRouterInterfaceGroupId OBJECT-TYPE
SYNTAX InetAddress (SIZE(4|16))
MAX-Access read-only
DESCRIPTION "The MGMD group id."
::= { mgmdNotificationObjects 2 }
mgmdHostGroups OBJECT-TYPE
SYNTAX Unsigned32
MAX-Access read-only
DESCRIPTION
"The total number of groups of which the host is a member."
::= { mgmdNotificationObjects 3 }
MgmdHostGroupsThreshold OBJECT-TYPE
SYNTAX Unsigned32
MAX-Access read-only
DESCRIPTION
"The maximum number of groups of which the host can become a
member of."
::= { mgmdNotificationObjects 4 }
mgmdWrongVersion NOTIFICATION-TYPE
OBJECTS { mgmdRouterInterfaceVersion,
mgmdInterfaceVersionReceived }
STATUS Current
DESCRIPTION
"A mgmdWrongVersion trap is sent when a general query whose
IGMP or MLD version does not match the equivalent
mgmdRouterInterfaceVersion. Both IGMP and MLD require that
all routers on a LAN be configured to run the same version.
Thus, if any general queries are received with the wrong
version, this indicates a configuration error."
::= { mgmdNotifications 1 }
mgmdInterfaceJoins NOTIFICATION-TYPE
OBJECTS { mgmdRouterInterfaceIfIndex,
mgmdRouterInterfaceGroupId}
STATUS Current
DESCRIPTION
"A mgmdInterfaceJoins trap is sent when a group membership,
given by mgmdRouterInterfaceGroupId, is added on a
interface, mgmdRouterInterfaceIfIndex."
::= { mgmdNotifications 2 }
mgmdGroupsExceed NOTIFICATION-TYPE
OBJECTS {mgmdHostGroups , MgmdHostGroupsThreshold }
STATUS Current
DESCRIPTION
"A mgmdGroupsExceed trap is sent when the number of groups,
mgmdHostGroups , of which the host is a member exceeds
MgmdHostGroupsThreshold value. When the number exceeds the
maximum capacity no more groups are learnt and flooding
becomes the default behavious for such groups."
::= { mgmdNotifications 3 }
mgmdInterfaceLastMemberLeave NOTIFICATION-TYPE
OBJECTS { mgmdRouterInterfaceIfIndex ,
mgmdRouterInterfaceGroupId}
STATUS Current
DESCRIPTION
"A mgmdInterfaceLastMemberLeave trap is sent when the last
member os group mgmdRouterInterfaceGroupId leaves on
interface mgmdRouterInterfaceIfIndex. As a result the
interface stops being the member of the respective group."
::= { mgmdNotifications 4}
6. Security Considerations
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 the notification provided
by two existing multicast protocols, Multicast Group Membership
Discovery.
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
mgmdNotificationMIB { mib-2 XXX }
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "XXX" under the 'mib-2' subtree and
to record the assignment in the SMI Numbers registry. When the
assignment has been made, the RFC Editor is asked to replace "XXX"
(here and in the MIB module) with the assigned value and to remove
this note.
