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]. 2. Introduction A multimedia terminal adapter (MTA) is used to deliver broadband Internet, data, and/or voice access jointly with telephony service to a subscriber's or customer's premises using a cable network infrastructure. A MTA is normally installed at the customer's or subscriber's premises, and it is coupled to a multiple system operator (MSO) using a hybrid fiber coax (HFC) access network. Beacham/Kumar/Channabasappa Expires - March 2006 [Page 2] PacketCable/IPCablecom NCS Signaling MIB September 2006 A MTA is provisioned by the MSO for broadband Internet, data, and/or voice service. For more information on MTA provisioning refer to [PKT-SP-PROV] and [RFCXYZ]. MTA devices include one or more endpoints (e.g., telephone ports) which receive call signaling information to establish ring cadence, and codecs used for providing telephony service. For more information on call signaling refer to [PKT-SP-MGCP] and [RFC3435]. For more information on codecs refer to [PKT-SP-CODEC]. Given the complexity of such systems it is important that a suitable event management mechanism be defined to allow for effective management. This MIB module provides objects suitable for generation and management of events on the MTA. 3. Terminology 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]. The terms "MIB module" and "information module" are used interchangeably in this memo. As used here, both terms refer to any of the three types of information modules defined in Section 3 of RFC 2578 [RFC2578]. Some of the terms used in this memo are defined below. Some additional terms are also defined in the PacketCable(TM) Management Event Mechanism Specification [PKT-SP-MEM1.5] and the PacketCable MTA Device Provisioning Specification [PKT-SP-PROV]. 3.1 PacketCable PacketCable is a CableLabs-led initiative that is aimed at developing interoperable interface specifications for delivering advanced, real-time multimedia services over two-way cable plants. 3.2 IPCableCom IPCableCom is an ITU Telecommunication Standardization Sector (ITU- T) project that includes architecture and a series of recommendations that enable the delivery of real time services over the cable television networks using cable modems. 3.3 MTA A Multimedia Terminal Adapter (MTA) is a PacketCable or IPCablecom compliant device providing telephony services over a cable or hybrid system used to deliver video signals to a community. It contains an Beacham/Kumar/Channabasappa Expires - March 2006 [Page 3] PacketCable/IPCablecom NCS Signaling MIB September 2006 interface to endpoints, a network interface, CODECs, and all signaling and encapsulation functions required for Voice over IP transport, call signaling, and Quality of Service signaling. A MTA can be an embedded or a standalone device. An Embedded MTA (E-MTA) is a MTA device containing an embedded Data Over Cable Service Interface Specifications (DOCSIS) Cable Modem. A Standalone MTA (S- MTA) is a MTA device separated from the DOCSIS Cable Modem by non- DOCSIS MAC interface (e.g., Ethernet, USB). 3.4 Endpoint An endpoint or MTA endpoint is a standard RJ-11 telephony physical port located on the MTA and used for attaching the telephone device to the MTA. 3.5 MSO Multi-System Operator. A cable company that operates many head-end locations in several cities. 3.6 UDP User Datagram Protocol. A connectionless protocol built upon Internet Protocol (IP), as per RFC 768 [RFC768]. 4. Overview This MIB module provides a set of objects required for generation and management of events on PacketCable, European Telecommunications Standards Institute (ETSI), and International Telecommunication Union Telecommunication Standardization Sector (ITU-T) IPCablecom compliant Multimedia Terminal Adapter (MTA) devices. The EVENT MIB module is intended to supersede various EVENT MIB modules from which it is partly derived: - the PacketCable 1.5 Management Event MIB Specification [PKT-SP-EVEMIB1.5], - the ITU-T IPCablecom management event mechanism MIB requirements [ITU-T-J176] Several normative and informative references are used to help define Management Event MIB objects. As a convention, wherever the requirements are equivalent at the time of the writing, the PacketCable reference is used. However, MTA implementations MUST refer to the corresponding specifications to ensure compliance. 4.1 Structure of the MIB This MIB is structured into six subtrees: Beacham/Kumar/Channabasappa Expires - March 2006 [Page 4] PacketCable/IPCablecom NCS Signaling MIB September 2006 - Management information that controls the event reporting (pktcDevEventControl). - Management information that configures the event throttling control (pktcDevEventThrottle). - Management information reflecting the status of the event transmission (pktcDevEventStatus). - Management information that specifies the possible events that can be generated by the MTA (pktcDevEventDescr). - Management information related to the events generated by the MTA (pktcDevEventLog). - Management information that defines the trap and inform messages (pktcDevEvNotifications). pktcDevEventControl The objects in this group contain information related to the destination Syslog Server and actions related to the event tables. pkctDevEvControl - this object defines the actions related to the event tables. pkctDevEvSyslogAddressType - this object defines the address type of the Syslog Server. pktcDevEvSyslogAddress - this object specifies the address of the Syslog server. pkctDevEvSyslogUdpPort - this object specifies the UDP-port to which the Syslog messages need to be send. pktcDevEventThrottle The objects in this group control the throttling of the reported events. pktcDevEventStatus The objects in this group relate to the status of the event transmissions. pktcDevEventDescr Beacham/Kumar/Channabasappa Expires - March 2006 [Page 5] PacketCable/IPCablecom NCS Signaling MIB September 2006 The objects in this group contain the description of the possible events that can be generated. pktcDevEventLog The objects in this group contain the management information related to the events that can be generated by the MTA. pktcDevEvNotifications The objects in this group define the structure for the SNMP trap and SNMP Inform notifications. 5. Relationship to Other MIB Modules Some management objects defined in other MIB modules are applicable to an entity implementing this MIB. In particular, it is assumed that an entity implementing the PKTC-IETF-EVENT-MIB module will also implement the 'interfaces' group of the IF-MIB [RFC2863]. 5.1 MIB modules required for IMPORTS The PKTC-IETF-EVENT-MIB MIB module IMPORTS objects from SNMPv2-SMI [RFC2578], SNMPv2-TC [RFC2579], SNMP-FRAMEWORK-MIB [RFC3411], SNMPv2-CONF [RFC2580], IF-MIB [RFC2863] and the INET-ADDRESS-MIB [RFC4001]. 6.

IANA Considerations The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER values recorded in the SMI Numbers registry: Descriptor OBJECT IDENTIFIER Value ---------- ----------------------- pktcIetfEventMib { 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. 11. Security Considerations Beacham/Kumar/Channabasappa Expires - March 2006 [Page 27] PacketCable/IPCablecom NCS Signaling MIB September 2006 There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write. 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. Security threats include events unreported on errors, redirection of events (deliberately or otherwise) or minimized reporting of errors. Such threats can mask certain misconfiguration attempts and denial of service attacks that can be recognized and thwarted via event reporting. MIB objects of significance include: - those that control the event generation, the target syslog address for events and the reporting status, i.e.: pktcDevEvControl pktcDevEvSyslogAddressType pktcDevEvSyslogAddress pktcDevEvSyslogUdpPort pktcDevEventReportStatus - those related to event classes, i.e.: pktcDevEventClassSeverityLevel - those related to throttling, i.e.: pktcDevEvThrottleAdminStatus pktcDevEvThrottleThreshold pktcDevEvThrottleInterval - those related to the event reporting capabilities of an MTA, i.e: pktcDevEventDescrSeverityLevel pktcDevEventDescrReporting pktcDevEventDescrText pktcDevEventDescrClass 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: pktcDevEventLogTable: This table contains the log of generated event messages. Read access to this table might reveal some specific information that should be kept confidential. Beacham/Kumar/Channabasappa Expires - March 2006 [Page 28] PacketCable/IPCablecom NCS Signaling MIB September 2006 pktcDevEvTransmissionStatus: This MIB Object reveals the status of event transmission and MAY be sensitive in some environments. 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. 12.
