1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines objects for monitoring and controlling
network devices with APPN (Advanced Peer-to-Peer Networking)
capabilities. This memo identifies managed objects for the APPN
protocol.
2. The SNMPv2 Network Management Framework
The SNMP Network Management Framework consists of several components.
For the purpose of this specification, the applicable components of
the Framework are the SMI and related documents [1, 2, 3], which
define the mechanisms used for describing and naming objects for the
purpose of management.
The Framework permits new objects to be defined for the purpose of
eXPerimentation and evaluation.
3. Overview
This document identifies a set of objects for monitoring the
configuration and active characteristics of devices with APPN
capabilities, and for controlling certain characteristics. APPN is
the ASPect of Systems Network Architecture (SNA) that supports peer-
to-peer networking. These networks transport both independent and
dependent LU session traffic. See the SNANAU APPC MIB [7] and the
SNA NAU MIB [8] for management of these sessions. See also the DLUR
MIB[9], and the HPR MIB[10] for management of extensions to the APPN
architecture. In this document, we describe APPN managed objects.
An APPN network comprises various types of nodes, and transmission
groups (TGs) that connect the nodes. Network nodes (NNs) provide
Directory and routing functions for session establishment. NNs may
be session end points or intermediate nodes in a session. A border
node is a type of network node that connects networks together for
session establishment without fully merging them. End nodes (ENs)
are session end points that receive directory and routing functions
from network nodes, over control-point to control-point (CP-CP)
sessions. Low-entry networking (LEN) nodes are also session end
points, but do not support CP-CP sessions, and therefore need
additional manual configuration definitions to establish sessions in
an APPN network. ENs and LEN nodes may have minimal directory and
routing functions to establish control sessions (ENs) or to connect
into the APPN network (LEN nodes). Virtual routing nodes (VRNs) are
not really nodes, but rather common definitions among actual nodes in
a shared transport facility such as a local area network (LAN) that
allow these actual nodes to temporarily establish a logical link with
one another without defining each other"s link-level addressing
information.
Ports and link stations are the node"s interface to the data link
control (DLC), which provides the physical transport, or to another
protocol such as Data Link Switching (DLSw), which provides transport
over an IP network. See the SNADLC SDLC MIB[11], the SNADLC LLC
MIB[12], and the DLSw MIB[13]. A link station uses a port to make a
connection to another node. This connection establishes a TG between
the two nodes.
The directory and routing functions enable an NN to find where an LU
is located in the network, and calculate the optimal route for the
session based on the requested class of service (COS). A network
node saves the LU information in a directory database, which is built
from LUs defined locally, LU registration from served end nodes, and
LUs learned from network searches.
Each NN maintains a local COS database that assigns a routing weight,
or relative cost, to each resource for each class of service. For
example, the #INTER COS assigns a lower weight to TGs with a greater
effective capacity, while the #BATCH COS favors TGs with a lower
relative cost per byte.
A node saves network topology information (on NNs, VRNs, and TGs
between them) in a network topology database. The topology
information includes state and routing characteristics. Topology
information is exchanged between NNs over CP-CP sessions such that
the database is fully replicated at each NN. Information on TGs from
NNs to ENs are kept in a local topology database. Local topology
information is shared with other NNs only during the session
establishment process, to give the NN responsible for route
calculation the necessary information for end-to- end route
calculation.
SNA names such as LU names, CP names, COS names, and mode names can
be padded with blanks (space characters) in SNA formats. These
blanks are nonsignificant. For example, in a BIND Request Unit (RU)
a COS name of "#INTER" with a length of 6 is identical to a COS name
of "#INTER " with a length of 8. However, in this MIB,
nonsignificant blanks are not included by the agent. Using the COS
name from the previous example, an agent would return a length of 6
and the string "#INTER" with no blanks for appnCosName, regardless of
how it appears in the BIND RU or in internal storage. The lone
exception is the all blank mode name, for which the agent returns a
length of 8 and the string " " (8 blank spaces). The MIB
variables that this applies to are identified by a textual convention
syntax that also describes this behavior.
When an SNA name is functioning as a table index, an agent treats
trailing blanks as significant. If a management station requests the
objects from a row with index "#INTER ", the agent does not match
this to the row with index "#INTER". Since an agent has no
nonsignificant blanks in any of its table indices, the only reason
for a Management Station to include them would be to start GetNext
processing at a chosen point in a table. For example, a GetNext
request with index "M " would start retrieval from a table at
the first row with an 8-character index beginning with "M" or a
letter after "M".
The SNA/APPN terms and overall architecture are documented in [4],
[5], [6], and [14].
Highlights of the management functions supported by the APPN MIB
module include the following:
o Activating and deactivating ports and link stations.
o Monitoring of configuration parameters related to the node,
ports, link stations, virtual routing nodes, and classes of
service.
o Monitoring of operational parameters related to ports, link
stations, virtual routing nodes, topology, directory, and
intermediate sessions.
o Historical information about link station errors during
connection establishment, or that caused the connection to
terminate.
o Deactivating intermediate sessions.
o Traps for SNA Management Services (SNA/MS) Alert conditions.
This MIB module does not support:
o Configuration of APPN nodes.
o Monitoring and control of endpoint sessions.
o Dependent LU Requester (DLUR) management.
o High-Performance Routing (HPR) management.
3.1. APPN MIB Structure
The APPN MIB module contains the following groups of objects:
o appnNode - objects related to the APPN node for all node types.
o appnNn - objects to represent the network nodes, virtual
routing nodes, and TGs between these nodes that make up the APPN
network topology database maintained in NNs.
o appnLocalTopology - objects to represent nodes and TGs between
nodes in the local topology database maintained in all nodes.
o appnDir - objects related to LU location information from the
node"s directory database.
o appnCos - objects related to classes of service information.
o appnSessIntermediate - objects related to intermediate sessions
that pass through this node.
These groups are described below in more detail.
3.1.1. appnNode group
The appnNode group consists of the following tables and objects:
1) appnGeneralInfoAndCaps
This group of objects describes general information about the APPN
node. The type of information includes the node type and the time
since this node was initialized.
2) appnNnUniqueInfoAndCaps
This group of objects describes information specific to network nodes
such as node routing characteristics.
3) appnEnUniqueInfoAndCaps
This group of objects describes information specific to end nodes,
including its network node server.
4) appnPortInformation
This includes the appnPortTable, which describes the configuration
and current status of the ports used by APPN, including the port
state and DLC type.
5) appnLinkStationInformation
This includes the appnNodeLsTable, which describes the configuration
and current status of the link stations used by APPN, including the
link state and port name; and the appnLsStatusTable, which provides
information about errors this node encountered with connections to
adjacent nodes, such as the sense data captured during connection
failures. It is a product option to decide how many
appnLsStatusTable entries are kept.
6) appnVrnInfo
This includes the appnVrnTable, which describes the relationship
between virtual routing nodes" TGs described in the appnLocalTgTable
with ports in the appnPortTable.
3.1.2. appnNn group
The appnNn group consists of the following objects and tables
1) appnNnTopo
These objects contain general information about the network topology
database including the number of nodes present, and the number of
topology database updates (TDU) wars the node has detected.
2) appnNnTopology
This includes tables representing the APPN network topology database.
This includes the network nodes, virtual routing nodes, and TGs
between these nodes, as well as the information about these resources
carried in topology updates. The tables are first indexed by the
same flow reduction sequence number (FRSN) used in topology exchanges
between NNs. This allows a management station to retrieve only
incremental updates, since the agent will update the FRSN of new or
changed resources.
3.1.3. appnLocalTopology group
The appnLocalTopology group consists of the following objects and
tables:
1) appnLocalThisNode
a) appnLocalGeneral
Contains the local node and type.
b) appnLocalNnSpecific
These objects contain routing information about the local network
node.
c) appnLocalTg
This table represents information about this node"s local TGs.
2) appnLocalEnTopology
This table represents TG information for EN TGs learned by the NN via
TG registration with the local node.
3.1.4. appnDir group
The appnDir group consists of the following objects and tables:
1) appnDirPerf
These objects represent information related to information about the
directory database and directory searches involving this node.
2) appnDirTable
This table represents the directory database, listing LUs known to
this node, along with the owning node of the LU and the serving NN of
the owning node.
3.1.5. appnCos group
The appnCos group consists of the following tables:
1) appnCosModeTable
This table represents the mode to class of service mapping.
2) appnCosNameTable
This table represents the tranmission priority for each class of
service.
3) appnCosNodeRowTable
This table represents the node-row information for each class of
service, including the weight of each node.
3) appnCosTGRowTable
This table represents the TG-row information for each class of
service, including the weight of each TG.
3.1.6. appnSessIntermediate group
The appnSessIntermediate group consists of the following objects and
tables:
1) appnIsInGlobal
These objects allow control of the collection of intermediate session
information such as Route Selection Control Vectors (RSCVs) and
counters.
2) appnIsInTable
This table contains information on active intermediate sessions.
3) appnIsRtpTable
This table contains information on active intermediate sessions that
are being transported on Rapid Transport Protocol (RTP) connections
by High Performance Routing (HPR).
3.1.7. appnTraps
One APPN trap is defined. It is intended to correspond to SNA/MS
Alerts, but is optional for a product to implement this trap. The
trap identifies the Alert ID number and, where possible, the affected
resource.

SnaNodeIdentification ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"An SNA Node Identification consists of two parts, which
together comprise four bytes of hexadecimal data. In SNA the
Node Identification is transported in bytes 2-5 of the XID.
The block number is the first three digits of the Node
Identification. These 3 hexadecimal digits identify the
product.
The ID number is the last 5 digits of the Node Identification.
These 5 hexadecimal digits are administratively defined and
combined with the 3-digit block number form the 8-digit Node
Identification. A unique value is required for connections to
SNA subarea. In some implementations, the value "bbb00000"
(where "bbb" represents a 3-digit block number) is returned to
mean that the ID number is not unique on this node.
An SNA Node Identification is represented as eight
ASCII-encoded hexadecimal digits, using the characters "0" -
"9" and "A" - "F"."

DESCRIPTION
"A fully qualified SNA control point name, consisting of a 1 to
8 character network identifier (NetId), a period ("."), and a 1
to 8 character control point name (CpName).
The NetId and CpName are constructed from the uppercase letters
"A" - "Z" and the numerics "0" - "9", all encoded in ASCII,
with the restriction that the first character of each must be
a letter. Trailing blanks are not allowed.
Earlier versions of SNA permitted three additional characters
in NetIds and CpNames: "#", "@", and "$". While this use of
these characters has been retired, a Management Station should
still accept them for backward compatibility."
SYNTAX OCTET STRING (SIZE (3..17))
SnaClassOfServiceName ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"An SNA class-of-service (COS) name, ranging from 1 to 8
ASCII characters. COS names take one of two forms:
- a user-defined COS name is constructed from the uppercase
letters "A" - "Z" and the numerics "0" - "9", with the
restriction that the first character of the name must be
a letter.
- an SNA-defined user-session COS name begins with the
character "#", which is followed by up to seven
additional characters from the set of uppercase letters
and numerics.
Trailing blanks are not allowed in either form of COS name.
A zero-length string indicates that a COS name is not
available."
SYNTAX OCTET STRING (SIZE (0..8))
SnaModeName ::= TEXTUAL-CONVENTION
