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 RFC2119 [17].

2. The SNMP Network Management Framework

The SNMP Management Framework presently consists of five major

components:

o An overall architecture, described in RFC2271 [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, RFC1155 [2], STD 16, RFC1212 [3] and RFC1215 [4]. The

second version, called SMIv2, is described in STD 58, RFC2478

[5], RFC2579 [6] and RFC2580 [7].

o Message protocols for transferring management information. The

first version of the SNMP message protocol is called SNMPv1 and

described in STD 15, RFC1157 [8]. A second version of the SNMP

message protocol, which is not an Internet standards track

protocol, is called SNMPv2c and described in RFC1901 [9] and

RFC1906 [10]. The third version of the message protocol is

called SNMPv3 and described in RFC1906 [10], RFC2272 [11] and

RFC2274 [12].

o Protocol operations for Accessing management information. The

first set of protocol operations and associated PDU formats is

described in STD 15, RFC1157 [8]. A second set of protocol

operations and associated PDU formats is described in RFC1905

[13].

o A set of fundamental applications described in RFC2273 [14] and

the view-based access control mechanism described in RFC2275

[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.

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 RFC2353 [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, RFC2238 [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 RFC2474 [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:

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 (RFC2011),

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

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

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.

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.
