Abstract This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it provides a common data and format definition for events and specifies by what means events are transmitted for PacketCable/IPCablecom compliant Multimedia Terminal Adapter devices. This memo specifies a MIB module in a manner that is compliant to the SNMP SMIv2 [5][6][7]. The set of objects are consistent with the SNMP framework and existing SNMP standards.

The SNMP Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2571 [1]. o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The second version, called SMIv2, is described in STD 58, RFC 2578 [5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and RFC 2574 [12]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [8]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [13]. o A set of fundamental applications described in RFC 2573 [14] and the view-based access control mechanism described in RFC 2575 [15]. A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [16]. De Ketelaere/Nechamkin Expires December 2002 [Page 2] Internet Draft PacketCable event management MTA MIB June 2002 Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB MUST be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB. 2.

Overview This MIB provides a set of objects required for the management of PacketCable/IPCablecom compliant MultiMedia Terminal Adapter (MTA) devices. The mechanisms to control the event reporting are defined in this document. 3.1. Structure of the MIB This MIB is structured as six groups: o Management information that controls the event reporting (pktcDevEventControl). o Management information that configures the reporting of the various programmable events (pktcDevEventConfig). o Management information that configures the event throttling control De Ketelaere/Nechamkin Expires December 2002 [Page 7] Internet Draft PacketCable event management MTA MIB June 2002 (pktcDevEventThrottle). o Management information that configures that allows the retrieval of events via SNMP (pktcDevEventLocal). o Management information that specifies the information sent in traps and informs (pktcDevEventNotify). o Management information that defines the trap and inform messages (pktcDevEventNotification). Tables within each of these groups group objects functionally. 3.1.1. pktcDevEventControl The objects in the pkctDevEventControl group control to where the syslog messages will be send to and the clearing of the event log. pkctDevEvControl - - this object is used to reset the event log and restore the default event reporting settings. pkctDevEvSyslogAddressType - - the type of internet address for the syslog server, it is not necessary to support all types. pktcDevEvSyslogAddress - - the IP-address of the syslog server, this can also be a FQDN, although the use of FQDN is discouraged. ?? Unicast vs broadcast pkctDevEvSyslogUdpPort - - this object specifies the UDP-port to which the syslog messages need to be send. 3.1.2. pktcDevEventConfig pktcDevEvProgrammableTable - This table configures the reporting of various programmable events. By the use of this table it is possible to configure specific events to have a specific priority or report a specific event message. Additionaly the way of reporting (e.g. local, syslog, .. ) can be controlled. pktcDevEvFixedTable - This table configures the reporting of fixed events. By the use of this table it is possible to configure specific events to have a specific priority or report a specific event message. Additionaly the way of reporting (e.g. local, syslog, .. ) can be controlled. 3.1.3. pktcDevEventThrottle This group of objects controls the throttling of reporting events. 3.1.4. pktcDevEventLocal pktcDevEventTable - - this tables contains a log of network and device events that can be retrieved by SNMP. The table can be cleared by using pkctDevEvControl. De Ketelaere/Nechamkin Expires December 2002 [Page 8] Internet Draft PacketCable event management MTA MIB June 2002 3.1.5 pktcDevEventNotify This group specifies the event data for Traps and Informs. 3.1.6 pktcDevEvNotification The structure for the traps and informs is defined in this group. 4.

Security Considerations This MIB relates to a system which will provide metropolitan public telephony service. As such, improper manipulation of the objects represented by this MIB may result in denial of service to a large number of end-users. Improper manipulation of certain tables (e.g. pktcDevEventThrottle) can result in the generation of a lot of network load. SNMPv1 by itself is not a secure environment. Even if the network itself is secure (for example by using IPSec), even then, there is no De Ketelaere/Nechamkin Expires December 2002 [Page 24] Internet Draft PacketCable event management MTA MIB June 2002 control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB. It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2574 [12] and the View- based Access Control Model RFC 2575 [15] is recommended. It is then a customer/user responsibility to ensure that the SNMP entity giving access to an instance of this MIB, 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. 8.
