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 proposes a mapping of IPP notifications over SNMP via new service and job trap extensions defined for the Job Monitoring MIB [RFC-2707]. This mapping may be used to deliver printer notifications for any printer (not just IPP-capable ones) and also job notifications for any job (not just ones submitted via IPP). This document proposes (4) new object groups and (4) new SNMP traps for addition to the Job Monitoring MIB [RFC 2707]. A working copy of this proposal integrated into the original Job Monitoring MIB ASN.1 is at: ftp://ftp.pwg.org/pub/pwg/ipp/new_NOT/jmp-trap-000706.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 proposes support for dynamic monitoring of IPP Printer and Job objects via SNMP traps generated by the service provider (server or device). 1.1. 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. SNMP Network Management Framework See: Section 1.1 'SNMPv1', section 1.2 'SNMPv2', and section 1.3 'SNMPv3' of [RFC-2576].

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" = 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: 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' Hastings, McDonald Expires 6 January 2001 [Page 6] Internet Draft IPP Notify - Job Monitoring MIB Traps 6 July 2000 - 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.

IANA Considerations None. 6. Internationalization Considerations The 'jmServiceStateReasons', 'jmServiceEventServiceStateReasons', 'jmServiceEventNotifyEvent', and 'jmJobEventNotifyEvent', text string objects defined in this document are of type 'SnmpAdminString' (UTF-8 stream-encoded ISO 10646/Unicode text) defined in the SNMPv3 Framework MIB [RFC-2571]. The natural language of these objects is US English (they contain keywords). 7. Security Considerations This IPP Notifications over SNMP mapping defines only 'read-only' objects. It is suitable for use with any version of SNMP, as no update security is required (because no configuration updates are supported). No sensitive information is available via IPP Notifications over SNMP. Hastings, McDonald Expires 6 January 2001 [Page 24] Internet Draft IPP Notify - Job Monitoring MIB Traps 6 July 2000 8.

Change Log Changes in reverse chronological order (most recent first). - 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. 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 Hastings, McDonald Expires 6 January 2001 [Page 26] Internet Draft IPP Notify - Job Monitoring MIB Traps 6 July 2000 '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/ [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 Hastings, McDonald Expires 6 January 2001 [Page 27] Internet Draft IPP Notify - Job Monitoring MIB Traps 6 July 2000 1) Initial version.
