RFC 2584 APPN/HPR in IP Networks MIB May 1999
1. Introduction
This document is a product of the SNA NAU Services MIB Working Group.
It defines a MIB module for managing devices with 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 presently consists of five major
components:
o An overall architecture, described in RFC 2271 [1].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and 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].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
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 described in RFC 1901 [9] and
RFC 1906 [10]. The third version of the message protocol is
called SNMPv3 and described in RFC 1906 [10], RFC 2272 [11] and
RFC 2274 [12].
o 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].
o A set of fundamental applications described in RFC 2273 [14] and
the view-based access control mechanism described in RFC 2275
[15].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
Clouston & Moore Standards Track [Page 2]
RFC 2584 APPN/HPR in IP Networks MIB May 1999
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 provides fast data routing
and improved session reliability. APPN is the aspect 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 provides a method with
which APPN/HPR nodes can 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:
o A count of UDP packets sent with each type of APPN traffic on
HPR/IP links.
o Monitoring and setting configuration parameters for the mappings
between APPN traffic types on 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:
o 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 using IP as the transport with the following objects:
Clouston & Moore Standards Track [Page 3]
RFC 2584 APPN/HPR in IP Networks MIB May 1999
o appnPortDlcType
o appnLsDlcType
o appnLsStatusDlcType
These objects all have the syntax IANAifType, and 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 the
following objects:
o appnPortDlcLocalAddr
o appnLsLocalAddr
o appnLsRemoteAddr
o appnLsStatusLocalAddr
o appnLsStatusRemoteAddr
These objects have the syntax DisplayableDlcAddress, defined in the
APPN MIB as a textual convention to represent the address as an octet
string of ASCII characters.
The following two objects return object identifiers that tie port and
link table entries in the APPN MIB to lower-layer MIB entries:
o appnPortSpecific
o appnLsSpecific
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:
o hprIpMonitoringGroup - an object for counting outgoing HPR/IP
traffic for each APPN traffic type
Clouston & Moore Standards Track [Page 4]
RFC 2584 APPN/HPR in IP Networks MIB May 1999
o hprIpConfigurationGroup - objects to represent TOS Precedence to
APPN traffic type mappings
These groups are described below in more detail.
3.2.1. hprIpMonitoringGroup
The hprIpMonitoringGroup group consists of the hprIpActiveLsTable.
This table is indexed by the link station name and traffic type, and
contains a counter for the number of UDP packets sent on a link
station for that traffic type.
3.2.2. hprIpConfigurationGroup
The hprIpMonitoringGroup group consists of the following objects and
tables:
1) 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.
2) 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.
3) 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
Clouston & Moore Standards Track [Page 6]

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."

5. Security Considerations
Certain management information defined in this MIB may be considered
sensitive in some network environments. Therefore, authentication of
received SNMP requests and controlled access to management
information SHOULD be employed in such environments. An
authentication protocol is defined in [12]. A protocol for access
control is defined in [15]. It is a customer responsibility to
properly set up access control for MIB access.
Clouston & Moore Standards Track [Page 16]
RFC 2584 APPN/HPR in IP Networks MIB May 1999
None of the read-only objects in this MIB reports a password, user
data, or anything else that is particularly sensitive. Some
enterprises view their network configuration itself, as well as
information about network usage and performance, as corporate assets;
such enterprises may wish to restrict SNMP access to most of the
objects in the MIB.
The one read-write and four read-create objects in the MIB can affect
network operations; it is recommended that SNMP access to these
objects be restricted. The five objects are:
o 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.
o hprIpLsTOSPrecedence: Setting this object has the potential for
delay or disruption for this link station as described above
with hprIpPortTOSPrecedence.
o 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.
o hprIpCnTOSPrecedence: Setting this object has the potential for
delay or disruption for this links created for this connection
network as described above with hprIpPortTOSPrecedence.
o 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.
