PRINTER-PORT-MONITOR-MIB: View SNMP OID List / Download MIB

The MIB module for printer port monitor support. Copyright (C) IEEE/ISTO PWG (2005).

The natural language tag (RFC 3066), specified in US-ASCII, for all localized text string objects defined in this MIB (syntax of 'SnmpAdminString'), or the empty string if not specified. For example, 'fr-CH' (French as written in Switzerland). Compatibility Note: At the time of publication of this MIB, language tags are restricted to US-ASCII. In order to support possible future evolution of languages tags (in a successor to RFC 3066) to allow non-ASCII characters, this object has been defined with a syntax of UTF-8 (RFC 3629). This natural language tag is necessary for support of correct glyph selection for text display, for support of text-to- speech, for support of correct sorting of text values, etc. If this object is empty, then the natural language for all localized text string objects in this MIB MUST default to 'en-US' (US English).

The number of printers supported on this network system, i.e., the number of entries in the 'ppmPrinterTable' below, or zero if no printers are currently configured.

The number of printer ports supported on this network system, i.e., the number of entries in the 'ppmPortTable' below, or zero if no printer ports are currently configured.

A table containing a list of printers configured on this network system, especially for use by operating systems to facilitate selection and automatic installation of device drivers.

An entry containing one printer configured on this network system, especially for use by operating systems to facilitate selection and automatic installation of device drivers.

A locally unique identifier for this network printer. The value of this object SHOULD be preserved (for each printer) across reboots and administrative configuration changes. If the value of 'ppmPortEnabled' is 'false' for all supported ports (i.e., ports with the same value of 'ppmPrinterIndex'), then applications MUST NOT attempt installation of this printer. Per SMIv2 (RFC 2578), the DEFVAL clause has been omitted on this 'not-accessible' index object.

A user friendly name for this printer that may be used to facilitate user selection of a printer supported by a network system, in the locale specified by 'ppmGeneralNaturalLanguage'. This printer name may contain non-ASCII characters that are NOT allowed in a URI (RFC 3986) without percent-encoding. Systems that implement the IETF Printer MIB v1 (RFC 1759) SHOULD implement this object as an augmentation to the Printer MIB v1. Systems that implement the IETF Printer MIB v2 (RFC 3805) MUST ensure that the value of this object is identical to the value of 'prtGeneralPrinterName' for each printer. The value of this object SHOULD be unique across all printers on this network system and SHOULD be meaningful to end users (e.g., 'PrinterXYZ'). The value of this object SHOULD be set by an out-of-band method (e.g., local console) during installation (by the vendor or site administrator) and SHOULD NOT be subsequently modified, so that the value can be used as a static key for access to the printer. The charset of this text string object is UTF-8 (RFC 3629), in order to support names that cannot be represented in US-ASCII.

The IEEE 1284 device ID for this printer, a set of capabilities (keys and values) specified in the US-ASCII charset and the format 'key1: value {, value }; ... keyN: value {,value };', as follows: (a) SPACE (0x20), TAB (0x09), VTAB (0x0B), CR (0x0D), NL (0x0A), and FF (0x0C) are allowed, but are ignored when parsing (b) other control characters (less than 0x20) MUST NOT be used (c) COLON (0x3A), COMMA (0x2C), and SEMICOLON (0x3B) are used as delimiters and MUST NOT be included in any key or value (d) each key MUST be separated from value(s) using COLON (0x3A) (e) multiple values MUST BE separated using COMMA (0x2C) (f) each capability MUST BE terminated using SEMICOLON (0x3B) (g) all printers MUST include the following capabilities - MANUFACTURER (or abbreviation MFG) - MODEL (or abbreviation MDL) (h) all printers MAY include the following capabilities - COMMAND SET (or abbreviation CMD) - COMMENT - ACTIVE COMMAND SET For example (actually all on one line of text): MANUFACTURER:ACME Manufacturing; COMMAND SET:PCL,PJL,PS,XHTML-Print+xml; MODEL:LaserBeam 9; COMMENT:Anything you like; ACTIVE COMMAND SET:PCL; The value of this object MUST exactly match the IEEE 1284-2000 Device ID string, except that the length field MUST NOT be specified. The value MUST be assigned by the Printer vendor and MUST NOT be localized by the Print Service. Compatibility Note: At the time of publication of this MIB, IEEE device IDs are restricted to US-ASCII. In order to support possible future evolution of IEEE device IDs (in a successor to IEEE 1284-2000) to allow non-ASCII characters, this object has been defined with a syntax of OCTET STRING to support the future use of UTF-8 (RFC 3629). If this object is empty, then the value of 'ppmPortProtocolType' for the selected port SHOULD be used to load a generic driver.

The number of printer ports supported on this network printer, i.e., the number of entries in the 'ppmPortTable' below with a first index of 'ppmPrinterIndex', or zero if no printer ports are currently configured.

The value of 'ppmPortIndex' for the preferred port for this printer (configured by vendor or site administrator), or zero if not specified. Compatibility Note: The value of zero is NOT valid for 'ppmPortIndex'. It is an out-of-band value. If this object is non-zero, then installation applications SHOULD default to this port in their user interface dialogue.

The value of 'hrDeviceIndex' in the IETF Host Resources MIB (RFC 1514/2790), or zero if not specified. This value of 'hrDeviceIndex' MAY be used for status queries for this printer if the value of 'ppmPrinterSnmpQueryEnabled' is 'true'. Compatibility Note: The value of zero is NOT valid for 'hrDeviceIndex'. It is an out-of-band value. If this object is zero, then monitoring applications MUST NOT attempt status queries for this printer in the IETF Host Resources MIB (RFC 1514/2790) and/or IETF Printer MIB (RFC 1759/3805).

The SNMP read community name, an opaque binary string, for access to status information in IETF Host Resources MIB (RFC 1514/2790) and IETF Printer MIB (RFC 1759/3805) for this printer via the value of 'ppmPrinterHrDeviceIndex' (i.e., a 'MIB view' of these two MIBs). Security Warning: Due to the widespread availability of free 'packet sniffers' (network traffic snooping applications) and SNMP packet decoders, SNMP community names no longer offer even weak security. This object SHOULD only be used to support 'MIB views'. Implementations SHOULD use SNMPv3 security to protect network resources from unauthorized monitoring. If this object is empty, then the SNMP read community name for this printer (if any) SHOULD default to 'public' in US-ASCII.

The status query mode for this printer, for queries by monitoring applications in the IETF Host Resources MIB (RFC 1514/2790) and/or IETF Printer MIB (RFC 1759/3805). If this object is 'true', then monitoring applications MAY attempt status queries for this printer in the IETF Host Resources MIB and/or IETF Printer MIB. If this object is 'false', then monitoring applications MUST NOT attempt status queries for this printer in the IETF Host Resources MIB and/or IETF Printer MIB.

A table containing a list of input printer ports configured on this network system, especially for use by operating systems to facilitate selection and automatic installation of device drivers.

An entry containing one input printer port configured on this network system, especially for use by operating systems to facilitate selection and automatic installation of device drivers.

A locally unique identifier for this printer port when appended to the value of 'ppmPrinterIndex' for this printer port. The value of this object SHOULD be preserved (for each port) across reboots and administrative configuration changes. Per SMIv2 (RFC 2578), the DEFVAL clause has been omitted on this 'not-accessible' index object.

The current administrative configuration mode for this port. If this object is 'false', then applications MUST NOT attempt installation of this port and SHOULD NOT attempt print job submission to this port. If this object is 'true', then the port is currently enabled. If this object is 'false', then the port is currently disabled.

A user friendly name for this port that may be used to facilitate user selection of a port on a multi-port network system, in the locale specified by 'ppmGeneralNaturalLanguage'. This port name may contain non-ASCII characters that are NOT allowed in a URI (RFC 3986) without percent-encoding. The value of this object SHOULD be unique across all ports on this network system and SHOULD be meaningful to end users (e.g., 'PrinterXYZ-LPR-Duplex'). The value of this object SHOULD be set by an out-of-band method (e.g., local console) during installation (by the vendor or site administrator) and SHOULD NOT be subsequently modified, so that the value can be used as a static key for access to the port. The charset of this text string object is UTF-8 (RFC 3629), in order to support names that cannot be represented in US-ASCII.

The service name or URI for this port, specified in UTF-8 (RFC 3629), in the locale specified by 'ppmGeneralNaturalLanguage'. The service name is typically a queue name. Compatibility Note: At the time of publication of this MIB, the Microsoft tools do not support LPR queue names longer than 32 characters. Network administrators SHOULD NOT assign longer LPR queue names, to prevent interworking problems. Compatibility Note: At the time of publication of this MIB, IETF URI Generic Syntax (RFC 3986) requires that all non-ASCII characters be percent-encoded, while IETF Internationalized Resource Identifiers (RFC 3987) permits native UTF-8 resource identifiers and supplies mappings to and from standard URI. In order to support current use of IRI and possible future evolution of URI (in a successor to RFC 3986) to allow non-ASCII characters, this object has been defined with a syntax of UTF-8 (RFC 3629). Examples of well-formed service URI for print protocols include: - 'lpr://foo.example.com/public-printer' (where 'public- printer' is the LPR queue name portion) and - 'ipp://bar.example.com/printer/fox' If this object is non-empty, then it SHOULD NOT conflict with a the default (e.g., IANA-registered) or explicit transport target port specified in 'ppmPortProtocolTargetPort'. In case of conflict, the URI value in 'ppmPortServiceNameOrURI' is authoritative (e.g., 'ipp://example.com:631/~smith/printer'). If this object is empty and 'ppmPortProtocolType' is 'chLPDServer(8)', the LPR queue name MUST default to 'LPR'.

The protocol type of this printer port, specified as a value from 'PrtChannelTypeTC' in the IANA Printer MIB (e.g., 'chLPDServer(8)' for LPR (RFC 1179) or 'chPort9100(11)' for Raw), or zero if not specified. Compatibility Note: The value of zero is NOT registered in the IANA Printer MIB. It is an out-of-band value. Thus the syntax of this object is NOT specified as 'PrtChannelTypeTC'. Systems that do NOT implement IETF Printer MIB v2 (RFC 3805) SHOULD use 'chPort9100(11)' for Raw printing (with an alternate port in 'ppmPortProtocolTargetPort', if necessary), because 'chPortTCP(37)' and 'chBidirPortTCP(38)' are NOT defined in IETF Printer MIB v1 (RFC 1759). Systems that do implement the IETF Printer MIB v2 (RFC 3805) MAY instead use 'chPortTCP(37)' or 'chBidirPortTCP(38)' for Raw printing, because 'chPort9100(11)' is DEPRECATED in IETF Printer MIB v2. Systems that implement any version of the IETF Printer MIB (RFC 1759/3805) SHOULD use the same value of protocol type for this port in the 'prtChannelTable', so monitoring applications MAY search for more channel information and status.

The transport (TCP, UDP, etc.) target port number for this protocol, i.e., an alternate port from the protocol default, or zero if not specified (use protocol default). This object MAY be used for any print protocol (from the Internet, NetWare, AppleTalk, or other protocol suite). If this object is zero, then the actual target port number is the default port for the specified 'ppmPortProtocolType' (e.g., 'chPort9100(11)' uses '9100'). If this object is non-zero, then it SHOULD NOT conflict with the default (e.g., IANA-registered) target port implied by the value of 'ppmPortProtocolType' or the explicit transport target port specified in 'ppmPortServiceNameOrURI'. In case of conflict, the URI value in 'ppmPortServiceNameOrURI' is authoritative (e.g., 'ipp://example.com:631/~smith/printer'). If 'ppmPortProtocolType' is 'chLPDServer(8)', then this object MUST be ignored (because LPR target port is fixed at '515').

The alternate transport source port mode for this protocol. If this object is 'true', then transport source ports outside the standard range MAY be used (e.g., LPR source port standard range is defined in RFC 1179 to be '721' to '731', inclusive). If this object is 'false', then transport source ports outside the standard range MUST NOT be used (to avoid protocol errors).

The value of 'prtChannelIndex' in IETF Printer MIB (RFC 1759/3805) that corresponds to this printer port, or zero if not specified. Compatibility Note: The value of zero is NOT valid for 'prtChannelIndex'. It is an out-of-band value. Systems that implement any version of the IETF Printer MIB (RFC 1759/3805) SHOULD correctly implement this object, so monitoring applications MAY search for print channel information and status. If this object is zero, then monitoring applications MUST NOT attempt print channel status queries for this printer port.

The current LPR byte counting mode for this port if applicable. If the value of 'ppmPortProtocolType' is NOT 'chLPDServer(8)', then monitoring applications MUST ignore the value of this object. If this object is 'true', then LPR byte counting is enabled. If this object is 'false', then LPR byte counting is disabled.
