Okay so this doc comes from the SNA NAU Services MIB Working Group 💅. It defines a MIB module for managing devices that have HPR in IP networks capabilities.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [17] 🔥.
2. The SNMP Network Management Framework 🍓
The SNMP Management Framework is currently made of five major components, so let's go through them 🫶:
- An overall architecture, described in RFC 2271 [1].
- Mechanisms for describing and naming objects and events for management purposes. The first version of this Structure of Management Information (SMI) is called SMIv1 and is 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 2478 [5], RFC 2579 [6] and RFC 2580 [7].
- Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and is described in STD 15, RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and is described in RFC 1901 [9] and RFC 1906 [10]. The third version of the message protocol is called SNMPv3 and is described in RFC 1906 [10], RFC 2272 [11] and RFC 2274 [12].
- 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].
- A set of fundamental applications described in RFC 2273 [14], plus the view-based access control mechanism described in RFC 2275 [15].
Managed objects are accessed through a virtual information store, called 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 🎀.
3. Overview 🦋
This document identifies a set of objects for monitoring the configuration and active characteristics of devices with HPR in IP network capabilities. HPR is an enhancement to the Advanced Peer-to-Peer Network (APPN) architecture that gives you fast data routing and better session reliability ⚡. APPN is the part of Systems Network Architecture (SNA) that supports peer-to-peer networking. APPN/HPR in IP Networks is a further enhancement to the APPN/HPR architecture, described in RFC 2353 [18]. It gives APPN/HPR nodes a way to communicate in IP networks 🌈.
APPN management information is defined by the APPN MIB [19]. HPR management information is defined by the HPR MIB, RFC 2238 [20] 💜.
Highlights of the management functions supported by the APPN/HPR in IP Networks MIB module include the following:
- A count of UDP packets sent with each type of APPN traffic on HPR/IP links.
- Monitoring and setting configuration parameters for the mappings between APPN traffic types and Type of Service (TOS) Precedence settings in the IP header. Note that the TOS Precedence settings have been redefined in RFC 2474 [21] as the first three bits of the differentiated services code point (DSCP).
This MIB module does not support:
- Configuration of IP addresses used for APPN ports or link stations.
3.1. HPR/IP Values for Objects in the APPN MIB 🍓
Ports and link stations are the APPN device's interface to the data link control (DLC), which provides the physical transport, or to another protocol, such as IP. The APPN MIB identifies ports and link stations that use IP as the transport with these objects:
appnPortDlcTypeappnLsDlcTypeappnLsStatusDlcType
These objects all have the syntax IANAifType. The value 126, defined as "IP (for APPN HPR in IP networks)", shall be returned when they identify an HPR/IP port or link station ✨.
The IP address used for the port or link station is returned in these objects:
appnPortDlcLocalAddrappnLsLocalAddrappnLsRemoteAddrappnLsStatusLocalAddrappnLsStatusRemoteAddr
These objects have the syntax DisplayableDlcAddress, which the APPN MIB defines as a textual convention for representing the address as an octet string of ASCII characters 🔥.
These two objects return object identifiers that tie port and link table entries in the APPN MIB to lower-layer MIB entries:
appnPortSpecificappnLsSpecific
Both objects should return a RowPointer to the ifEntry in the agent's ifTable for the physical interface associated with the local IP address for the port. If the agent implements the IP-MIB (RFC 2011), this association between the IP address and the physical interface will be represented in the ipNetToMediaTable 🫶.
3.2. APPN/HPR in IP Networks MIB Structure 🧚
The APPN/HPR in IP Networks MIB module contains two groups of objects:
- hprIpMonitoringGroup - an object for counting outgoing HPR/IP traffic for each APPN traffic type
- hprIpConfigurationGroup - objects that represent TOS Precedence to APPN traffic type mappings
These groups are described in more detail below 💅.
3.2.1. hprIpMonitoringGroup 🌸
The hprIpMonitoringGroup group consists of the hprIpActiveLsTable. This table is indexed by the link station name and traffic type, and it has a counter for the number of UDP packets sent on a link station for that traffic type 📊.
3.2.2. hprIpConfigurationGroup 🎀
Heads up bestie: this subsection's opening line says "hprIpMonitoringGroup", but it's the configuration group. That's how the original reads, so I kept it exactly as written 🙈.
The hprIpMonitoringGroup group consists of the following objects and tables:
hprIpAppnPortTable
This table supports reading and setting the default mapping between APPN traffic types and TOS Precedence settings for all link stations using a port. This mapping may be overridden for individual link stations or individual connection networks 💖.
hprIpLsTable
This table supports reading and setting the mappings between APPN traffic types and TOS Precedence settings for an individual link station and APPN traffic type. If there is no entry in this table for a given link station and traffic type, then that link station inherits its mapping from its port 🍓.
hprIpCnTable
This table supports reading and setting the mapping between APPN traffic types and TOS Precedence settings for an individual connection network and traffic type. If there is no entry in this table for a given connection network and traffic type, then that connection network inherits its mapping from its port 🌈.

DESCRIPTION
"The MIB module for HPR over IP. This module contains two
groups:
- the HPR over IP Monitoring Group provides a count of the UDP
packets sent by a link station for each APPN traffic type.
- the HPR over IP Configuration Group provides for reading and
setting the mappings between APPN traffic types and TOS
Precedence settings in the IP header. These mappings are
configured at the APPN port level, and are inherited by the
APPN connection networks and link stations associated with an
APPN port. A port-level mapping can, however, be overridden
for a particular connection network or link station."

END5. Security Considerations 🔐
Okay bestie, this part is SERIOUS 😭 Some of the management info in this MIB can be sensitive depending on the network, so authentication of received SNMP requests and controlled access to management information SHOULD be used in those environments. The authentication protocol is defined in [12], and the access control protocol is in [15]. It's the customer's job to set up access control for MIB access, periodt.
None of the read-only objects in this MIB reports a password, user data, or anything else that's particularly sensitive. Some enterprises treat their network configuration, plus info about network usage and performance, as corporate assets 💼. Those folks may want to restrict SNMP access to most of the objects in the MIB.
The one read-write and four read-create objects can actually affect network operations 🚨, so it is recommended that SNMP access to these objects be restricted. The five objects are:
hprIpPortTOSPrecedence: Setting this object immediately changes the mapping for all link stations using this port which do not have an entry to override the port value. Improper mappings may cause delays or disruptions in the network. For example, if APPN traffic type 'High' is mapped to IP TOS Precedence bits '001', network control traffic will have the same TOS precedence as bulk data traffic. This may cause delays with session initializations, and timeouts on control sessions that could cause network outages. 💀hprIpLsTOSPrecedence: Setting this object has the potential for delay or disruption for this link station as described above withhprIpPortTOSPrecedence. 🫠hprIpLsRowStatus: Setting this object to delete(6) causes this link station to revert to the default TOS Precedence mapping for its port. The customized mapping for this link station will no longer be in effect. 🧹hprIpCnTOSPrecedence: Setting this object has the potential for delay or disruption for this links created for this connection network as described above withhprIpPortTOSPrecedence. 🌪️hprIpCnRowStatus: Setting this object to delete(6) causes links created for this connection network to revert to the default TOS Precedence mapping for its port. The customized mapping for this connection network will no longer be in effect. 👋

10. Full Copyright Statement 🎀
Okay bestie, time for the legal bit, and yes, it's giving a whole wall of text, but it matters 💅. The Internet Society has copyright on this document from 1999, and it's all reserved, so nobody gets to just run off with it.
What you are allowed to do is copy it and hand it out to your friends 🫶. You can also write derivative works that comment on the doc, explain it, or help people actually build the thing, and you can publish and distribute those too. Whole doc or just parts, no restriction, as long as the copyright notice and this paragraph stay on every copy and derivative work. Slay 🔥.
Here's the catch, though 💀. The document itself can't be modified in any way. You can't strip the copyright notice, and you can't scrub out the references to the Internet Society or other Internet organizations. The one exception is when you're developing Internet standards, and then you have to follow the copyright procedures in the Internet Standards process. Translating it into languages other than English is also allowed.
The permissions above are perpetual 🌈. The Internet Society and its successors or assigns can't take them back later.
Last but not least, the document and everything in it is provided "AS IS" 🙈, and THE INTERNET SOCIETY AND THE INTERNET ENGINEERING TASK FORCE DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTY THAT THE USE OF THE INFORMATION HEREIN WILL NOT INFRINGE ANY RIGHTS OR ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. No promises, no guarantees, just vibes ✨.
