Introduction This document is a submission to the Internet Printing Protocol Working Group of the Internet Engineering Task Force (IETF). Comments should be submitted to the ipp@pwg.org mailing list. This document specifies an OPTIONAL mapping of IPP notifications over SNMP via new service and job trap extensions to the original Job Monitoring MIB [RFC-2707]. This mapping may be used to deliver printer notifications for any printer (not just IPP-capable ones) and also to deliver job notifications for any job (not just ones submitted via IPP). This document specifies (4) new object groups and (4) new SNMP traps for addition to the Job Monitoring MIB [RFC 2707]. A working copy of these extensions inserted in the original Job Monitoring MIB ASN.1 is at: ftp://ftp.pwg.org/pub/pwg/ipp/new_NOT/jmp-trap-000808.mib The IPP protocol [IPP-PRO] supports passive monitoring of IPP Printer and Job objects, via client polling of IPP object attributes using the 'Get-Printer-Attributes' and 'Get-Job-Attributes' operations. This document specifies support for dynamic monitoring of IPP Printer and Job objects via SNMP traps generated by the service provider (server or device). 2. Terminology 2.1. Terminology for Conformance The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted per [RFC-2119]. 2.2.

Subscription for IPP Notifications IPP Clients MAY subscribe for IPP Notifications delivered via SNMP by either of the following two standard methods: 3.2.1. Subscription via IPP IPP Job creation (Create-Job, Print-Job, Print-URI) and Create-Subscription operations MAY be used to create per-Printer or per-Job IPP Subscription objects and MAY specify: "notify-recipient-uri" = 'snmpnotify://hostname[.port]' "notify-events" = "notify-snmp-version" = "notify-snmp-auth-data" = "notify-snmp-operation" = "notify-snmp-mtu-size" = 3.2.2. Subscription via SNMP The SNMP Notification MIB and SNMP Target MIB (both in [RFC-2573]) MAY be used to create SNMP subscriptions. To create a subscription via SNMP, the IPP Client MAY use an SNMP Set-Request operation to create an appropriate row in the SNMP Notification MIB with the following variable-bindings: 1) 'snmpNotifyTag' - tag of this notification - see 'snmpTargetAddrTagList' below 2) 'snmpNotifyType' - deliver via SNMP Trap (unacknowledged) or Inform (acknowledged) 3) 'snmpNotifyStorageType' - persistence (volatile, nonVolatile, permanent, readOnly) Note: The SNMP Notification MIB uses persistence instead of the lease duration supported in IPP Subscription objects. To complete a subscription via SNMP, the IPP Client MAY use an SNMP Set-Request operation to create an appropriate row in the SNMP Target MIB with the following variable-bindings: Hastings, McDonald Expires 8 February 2001 [Page 7] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 1) 'snmpTargetAddrTDomain' and 'snmpTargetAddrTAddress' - notification target (client) transport protocol and address (corresponds to IPP 'notify-recipient-uri') 2) 'snmpTargetAddressTimeout' and 'snmpTargetAddrRetryCount' - retry timeout and limit (for acknowledged SNMP Inform only) 3) 'snmpTargetAddrTagList' - tags of notifications to be sent to this target (client) 4) 'snmpTargetAddrParamsEntry' - notification security and SNMP protocol version 5) 'snmpTargetAddrStorageType' - persistence (volatile, nonVolatile, permanent, readOnly) Note: The SNMP Target MIB uses persistence instead of the lease duration supported in IPP Subscription objects. 3.3. Relationship to other MIBs 3.3.1. MIB-II (RFC 1213) All SNMPv1 Trap messages include 'time-stamp' which is the value of the 'sysUpTime' object from MIB-II [RFC-1213]. All SNMPv2 trap bindings include the 'sysUpTime' object from MIB-II [RFC-1213]. 3.3.2. Host Resources MIB (RFC 2790) The 'jmServiceTable' defined in this document MAY have a sparse mapping to the 'hrDeviceTable' (same indices) in Host Resources MIB [RFC-2790]. 3.3.3. Printer MIB (RFC 1759) The 'jmServiceTable' defined in this document MAY have a sparse mapping to the 'hrDeviceTable' (same indices) in Host Resources MIB [RFC-2790], thus offering access to the Printer MIB via a 'hrDeviceIndex' value. Hastings, McDonald Expires 8 February 2001 [Page 8] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 4. General Information 4.1. Table 1 - Information about the Delivery Method Document Method Conformance Delivery Method Realization Requirement --------------------------- --------------------------- 1. What is the URL scheme name snmpnotify for the Delivery Method? 2. Is the Delivery Method OPTIONAL REQUIRED, RECOMMENDED or OPTIONAL for an IPP Printer to support? 3. What transport and delivery SNMP application layer protocols does the Printer use over UDP transport layer to deliver the Event over IP network layer Notification Content, i.e., over any datalink layer what is the entire network (or SNMP over any other stack? transport stack) 4. Can several Event No, impossible in SNMP Notifications be combined into (in an interoperable fashion) a Compound Event Notification? 5. Is the Delivery Method By the Printer (push) initiated by the Notification Recipient (pull), or by the Printer (push)? 6. Is the Event Notification Machine Consumable content Machine Consumable or Human Consumable? 7. What section in this document Section 7 'SNMP ASN.1 for answers the following for IPP Notifications'. question? For a Machine Consumable Event Notification, what is the representation and encoding of values defined in section 0 of [ipp-ntfy] and the conformance requirements thereof? For a Human Consumable Event Notification, what is the representation and Hastings, McDonald Expires 8 February 2001 [Page 9] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 encoding of pieces of information defined in section 9.2 of [ipp-ntfy] and the conformance requirements thereof? 8. What are the latency and The latency is minimal in reliability of the transport any network topology (all and delivery protocol? deployed transport mappings of SNMP are connectionless). The reliability is medium for SNMP Trap (unacknowledged) and high for SNMP Inform (acknowledged and optionally retried by the SNMP agent). 9. What are the security aspects SNMPv1 and SNMPv2 support of the transport and delivery community-based security with protocol, e.g., how it is very weak authentication. handled in firewalls? SNMPv3 (RFC 257x series) supports user-based security with strong authentication and MAY traverse firewalls (but usually does not). 10. What are the content length SNMP messages MUST be encoded restrictions? within the 'path MTU', i.e., the packet is NOT fragmented by the underlying network. In some IP networks, this results in a max payload of about 480 octets. See section 5.2.4 'notify-snmp-mtu-size'. 11. What are the additional The 'job-completed' SNMP values or pieces of notification delivers information that a Printer 'job-k-octets-processed' as sends in an Event Notification as well as the base required content and the conformance 'job-impressions-completed' requirements thereof? - and both are REQUIRED (for interoperability) 12. What are the additional See section 5.1 Subscription Template and/or 'Table 2 - Subscription Subscription Description and Printer Attributes' attributes and the conformance - all of the additional requirements thereof? subscription template attributes are REQUIRED (for interoperability) Hastings, McDonald Expires 8 February 2001 [Page 10] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 13.

This attribute specifies the SNMP protocol version and security model (e.g., community-based security in SNMPv1c IETF Standard [RFC-1157]) to use for delivery of this IPP Notification. Note: SNMP protocol versions and SNMP security models are NOT mutually independent - therefore they are combined in this single attribute. Hastings, McDonald Expires 8 February 2001 [Page 12] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 The following standard keyword values are defined: 'snmpv1-community': The SNMPv1 protocol with community-based security model defined in IETF Standard [RFC-1157]. 'snmpv1-party': The SNMPv1 protocol with party-based security model defined in IETF Historic [RFC-1352]. 'snmpv2-party': The SNMPv2 protocol with party-based security model defined in IETF Historic [RFC-1446]. 'snmpv2-community': The SNMPv2 protocol with community-based security model defined in IETF Experimental [RFC-1902]. 'snmpv2-user': The SNMPv2 protocol with user-based security model defined in IETF Experimental [RFC-1910]. 'snmpv3-user': The SNMPv3 protocol with user-based security model defined in IETF Draft Standard [RFC-2574]. 5.2.1.1. notify-snmp-version-default REQUIRED - for IPP Printers to implement. notify-snmp-version-default (type2 keyword) IPP Printer object attribute for IPP Notifications over SNMP. 5.2.1.2. notify-snmp-version-supported REQUIRED - for IPP Printers to implement. notify-snmp-version-supported (1setOf type2 keyword) IPP Printer object attribute for IPP Notifications over SNMP. 5.2.2. notify-snmp-auth-data (octetString(MAX)) REQUIRED - for IPP Printers to implement. This attribute specifies the SNMP protocol authentication data (e.g., a community name in SNMPv1c IETF Standard [RFC-1157]) to use for delivery of this IPP Notification. This data MAY be opaque (not human-readable). Human-readable authentication data in this attribute (e.g., an SNMPv1c or SNMPv2c community name) MUST be encoded in the UTF-8 [RFC-2279] transform of [ISO-10646] for interoperability. Hastings, McDonald Expires 8 February 2001 [Page 13] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 5.2.2.1. notify-snmp-auth-data-default REQUIRED - for IPP Printers to implement. notify-snmp-auth-data-default (octetString(MAX)) IPP Printer object attribute for IPP Notifications over SNMP. 5.2.2.2. notify-snmp-auth-data-supported REQUIRED - for IPP Printers to implement. notify-snmp-auth-data-supported (boolean) IPP Printer object attribute for IPP Notifications over SNMP. Note: The Printer attribute 'notify-snmp-auth-data-supported' has the irregular type 'boolean'. 5.2.3. notify-snmp-operation (type2 keyword) REQUIRED - for IPP Printers to implement. This attribute specifies the SNMP operation (e.g, SNMP Trap in SNMPv1c IETF Standard [RFC-1157]) to use for delivery of this IPP Notification. The following standard keyword values are defined: 'trap': An SNMP Trap PDU encoded in the version specified by "notify-snmp-version" above. Note: SNMP Trap is an unconfirmed operation (i.e., the notification recipient MUST NOT reply with an acknowledgement) and MUST NOT be retried by the notification generator. 'inform': An SNMP Inform PDU encoded in the version specified by "notify-snmp-version" above. Note: SNMP Inform is a confirmed operation (i.e., the notification recipient MUST reply with an acknowledgement Inform-Response) and MAY be retried by the notification generator. 'report': An SNMP Report PDU encoded in the version specified by "notify-snmp-version" above Warning: The use of SNMP Report MAY not be interoperable. Hastings, McDonald Expires 8 February 2001 [Page 14] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 5.2.3.1. notify-snmp-operation-default REQUIRED - for IPP Printers to implement. notify-snmp-operation-default (type2 keyword) IPP Printer object attribute for IPP Notifications over SNMP. 5.2.3.2. notify-snmp-operation-supported REQUIRED - for IPP Printers to implement. notify-snmp-operation-supported (1setOf type2 keyword) IPP Printer object attribute for IPP Notifications over SNMP. 5.2.4. notify-snmp-mtu-size (integer(0:MAX)) REQUIRED - for IPP Printers to implement. This attribute specifies the SNMP path maximum transmission unit (MTU) size in octets to use for delivery of this IPP Notification. The SNMP path MTU is defined as the size of the complete SNMP message envelope, header, and body - but NOT of the underlying transport, network, and datalink headers - such that NO fragmentation is required for the SNMP message at ANY lower layer of the protocol stack OR on any segment of the bridged or routed delivery path (optimally). This attribute enhances the integrity and probability of SNMP delivery. This attribute may signal the need for algorithmic truncation of some string variable bindings in the SNMP notification which MAY not fit in very small path MTU sizes. See: 'ifMtu' in the Interfaces group of IETF MIB-II [RFC-1213]. 5.2.4.1. notify-snmp-mtu-size-default REQUIRED - for IPP Printers to implement. notify-snmp-mtu-size-default (integer(0:MAX)) IPP Printer object attribute for IPP Notifications over SNMP. Hastings, McDonald Expires 8 February 2001 [Page 15] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 5.2.4.2. notify-snmp-mtu-size-supported REQUIRED - for IPP Printers to implement. notify-snmp-mtu-size-supported (rangeOfInteger(0:MAX)) IPP Printer object attribute for IPP Notifications over SNMP. 5.3. Additional Info about Subscription Template Attributes 5.3.1. notify-recipient-uri (uri) This section describes the syntax of the value of this attribute for the 'snmpnotify' Delivery Method for IPP Notifications. The syntax for values of this attribute for other Delivery Methods for IPP Notifications is defined in each method's specification. In order to support the 'snmpnotify' Delivery Method, the Printer MUST support the following syntax for the 'snmpnotify' Delivery Method when the Printer uses SNMP to deliver IPP Notifications. The lines below use RFC 2396 syntax rules, terms, and ABNF productions: "snmpnotify://" hostport hostport = host [ ":" port ] host = hostname | IPv4address hostname = *( domainlabel "." ) toplabel [ "." ] domainlabel = alphanum | alphanum *( alphanum | "-" ) alphanum toplabel = alpha | alpha *( alphanum | "-" ) alphanum IPv4address = 1*digit "." 1*digit "." 1*digit "." 1*digit port = *digit alphanum = alpha | digit alpha = lowalpha | upalpha lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" | "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" | "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z" upalpha = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H" | "I" | "J" | "K" | "L" | "M" | "N" | "O" | "P" | "Q" | "R" | "S" | "T" | "U" | "V" | "W" | "X" | "Y" | "Z" digit = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" Hastings, McDonald Expires 8 February 2001 [Page 16] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 6.

Change Log [This section will be deleted before publication as an RFC] Changes in reverse chronological order (most recent first). - 8 August 2000 1) Deleted 'printer-full', 'printer-no-longer-full', 'printer-almost-idle', and 'printer-not-almost-idle' event types, and added 'printer-stopped' in 'jmServiceEventNotifyTriggerEvent', for alignment with revised [IPP-NOT]; 2) Deleted 'job-purged' event type and added 'job-stopped' in 'jmJobEventNotifyTriggerEvent', for alignment with revised [IPP-NOT]; 3) Renamed 'jmServiceEventNotifyEvent' object to 'jmServiceEventNotifyTriggerEvent' (most specific event) and added 'jmServiceEventNotifyGroupEvent' (most general event), for higher fidelity mapping to IPP 'notify-subscribed-event'; 4) Renamed 'jmJobEventNotifyEvent' object to 'jmJobEventNotifyTriggerEvent' (most specific event) and added 'jmJobEventNotifyGroupEvent' (most general event), for higher fidelity mapping to IPP 'notify-subscribed-event'; 5) Renamed all NOTIFICATION-TYPEs (traps) for clarity, changing 'jmServiceBasicV2Event' to 'jmServiceEventV2Notify', 'jmJobBasicV2Event' to 'jmJobEventV2Notify', 'jmJobCompletedV2Event' to 'jmJobCompletedV2Notify', and 'jmJobProgressV2Event' to 'jmJobProgressV2Notify'. - 6 July 2000 1) Added 'SnmpAdminString' to IMPORTS clause for new objects. 2) Corrected OID in MODULE-IDENTITY to use forward reference to definition of 'pwg' from 'enterprises' and 'mibs' from 'pwg'. 3) Added 'JmServiceStateTC' textual convention. 4) Added 'jmMirrorAttr' and 'jmSystem' object identifiers reserved for future extensions. 5) Major rewrite, per email discussion on IETF IPP WG list, to specify four new small (traditional) SNMP traps for: 'jmServiceBasicV2Event' (generalized from IPP Printer event), 'jmJobBasicV2Event' (corresponds IPP Job event), 'jmJobCompletedV2Event' (corresponds IPP Job completed event), 'jmJobProgressV2Event' (corresponds IPP Job progress event). 6) Major rewrite, per email discussion on IETF IPP WG list, to specify four new SNMP object groups: 'jmServiceTable' (name, URI, state, etc. - from IPP Printer), 'jmServiceEventTable' (records IPP Printer events for polling), 'jmJobEventTable' (records IPP Job events for polling), 'jmJobProgressGroup' (leaf objects for IPP Job progress event). 7) Revised section 3.1 'SNMP Mapping for IPP Printer Events' and section 3.2 'SNMP Mapping for IPP Job Events', to agree with above. Hastings, McDonald Expires 8 February 2001 [Page 40] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 8) Deleted obsolete section 3.3 'Rules for Encoding Notifications', as event bindings now always fit over all SNMP transport protocols. - 19 March 2000 1) Renamed Printer Event notification group to Device Basic Event and 'jmPrinterEventV2Event' notification to 'jmDeviceBasicV2Event', to better align with IPP and to support non-printing jobs. 2) Revised 'jmDeviceBasicV2Event' notification to remove 'hrDeviceStatus', 'hrPrinterStatus', 'hrPrinterDetectedErrorState' from mandatory trap bindings because they were redundant, per request of Ron Bergman. 3) Renamed Job Event notification group to Job Basic Event and 'jmJobEventV2Event' notification to 'jmJobBasicV2Event', to better align with IPP and to support variant job events. 4) Defined new Job Completed Event notification group and defined new Job Progress Event notification group, to better align with IPP and to support variant job events. 5) Renamed Event object group to Event Binding, 'jmEventPrinterState' to 'jmEventDeviceState', 'jmEventPrinterStateReasons' to 'jmEventDeviceStateReasons', 'jmEventPrinterIsAcceptingJobs' to 'jmEventDeviceIsAcceptingJobs', to support non-printing jobs. 6) Revised Event Binding object group, adding explicit objects 'jmEventDeviceURI', 'jmEventDeviceName', 'jmEventJobSetIndex', 'jmEventJobIndex', 'jmEventJobName', 'jmEventJobState', 'jmEventJobStateReasons', 'jmEventJobKOctets', 'jmEventJobKOctetsProcessed', 'jmEventJobImpressions', 'jmEventJobImpressionsCompleted', 'jmEventJobMediaSheets', 'jmEventJobMediaSheetsCompleted', 'jmEventJobImpressionsCompletedCC', 'jmEventJobCollationType', 'jmEventJobSheetCompletedCopyNum', 'jmEventJobSheetCompletedDocNum', per request of Ron Bergman. 7) Revised SYNTAX of 'jmEventTriggerEvent' object from from 'JmUTF8StringTC' (string) to IPP-aligned enumeration, per request of Ron Bergman. 8) Removed all references to Printer MIB v2, as they were of limited value, per request of Ron Bergman. 9) Revised 'SNMP Mapping for IPP Printer Events' section for renamed event binding objects, per request of Ron Bergman. 10) Revised 'Rules for Encoding Notifications' section to truncate additional string bindings, per request of Ron Bergman. 11) Revised 'Registration via IPP' section, to change scheme name from 'ipp-snmp:' to 'snmpnotify:', per request of Ron Bergman. - 1 December 1999 1) Deleted 'JmTriggerEventTC' textual convention (see below). 2) Revised SYNTAX of 'jmEventTriggerEvent' object from 'JmTriggerEventTC' (enumeration) to 'JmUTF8StringTC' (string), to support use of IPP standard keywords. 3) Added 'jmEventPrinterState', 'jmEventPrinterStateReasons', and 'jmEventPrinterIsAcceptingJobs' objects for consistency w/ Hastings, McDonald Expires 8 February 2001 [Page 41] Internet Draft IPP Notify via Job Mon MIB Traps 8 August 2000 [IPP-NOT] and to reduce ambiguity about printer states inherent in RFC 1759. 4) Revised DESCRIPTION of 'jmPrinterEventV2Event' notification to add SHOULD (recommendation) for 'jmEventPrinterState', 'jmEventPrinterStateReasons', and 'jmEventPrinterIsAcceptingJobs' objects. 5) Revised 'SNMP Mapping for IPP Printer Events' section to add direct mapping of IPP notification attributes to 'jmEventPrinterState', 'jmEventPrinterStateReasons', and 'jmEventPrinterIsAcceptingJobs' objects. 6) Revised 'Rules for Encoding Notifications' section to add 'jmEventPrinterState' and 'jmEventPrinterStateReasons'. 7) Revised 'IANA Considerations' section to specify there are none - no enumerated or keyword textual conventions are now defined in this document. 8) Revised 'Internationalization Considerations' section to specify that US English keywords are used in 'jmEventTriggerEvent', 'jmEventPrinterState', and 'jmEventPrinterStateReasons' objects and thus no explicit natural language tagging is required. - 10 October 1999 1) Initial version.
