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 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.

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 (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. De Ketelaere/Nechamkin Expires August 2004 [Page 7] Internet Draft PacketCable event management MTA MIB February 2004 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. 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 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: pktcDevEventControl: This table controls to where events will be sent. Network operations can be impacted if insufficient security is provided pktcDevEventConfig: This table configures the type of events that will be reported, as such it has an influence on the number of messages that will be transmitted on the network. If not configured properly the network might get flooded with messages. pktcDevEventThrottle: This table controls the rate at which events can be generated, if not configured properly, the network load caused by event event messaging might severely impact network performance. 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 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: De Ketelaere/Nechamkin Expires August 2004 [Page 25] Internet Draft PacketCable event management MTA MIB February 2004 pktcDevEventLocal: This table contains the log of event messages. Read access to this table might reveal some specific information that should be kept confidential. 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. 9.
