RFC 2155 Definitions of Managed Objects for APPN June 1997
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'."
SYNTAX OCTET STRING (SIZE (8))
SnaControlPointName ::= TEXTUAL-CONVENTION
STATUS current
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
Clouston & Moore Standards Track [Page 10]
RFC 2155 Definitions of Managed Objects for APPN June 1997
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
STATUS current
DESCRIPTION
"An SNA mode name, ranging from 1 to 8 ASCII characters.
Mode names take one of two forms:
- a user-defined mode 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 mode 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 mode name,
with the single exception of the all-blank mode name, where
a string consisting of 8 blanks is returned.
A zero-length string indicates that a mode name is not
available."

SYNTAX OCTET STRING (SIZE (0..8))
SnaSenseData ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"To facilitate their display by a Management Station, sense
data objects in the MIB are represented as OCTET STRINGS
containing eight ASCII characters. Eight '0' characters
indicates that no sense data identifying an SNA error
condition is available.
An SNA sense data is represented as eight hexadecimal digits,
using the characters '0' - '9' and 'A' - 'F'."
SYNTAX OCTET STRING (SIZE (8))
DisplayableDlcAddress ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"DLC address of a port or link station, represented as an
OCTET STRING containing 0 to 64 ASCII characters.
A Management Station should use a value of this type only
for display. The 'real' DLC address, i.e., the sequence of
bytes that flow in the DLC header, is often available in a
DLC-specific MIB.
The zero-length string indicates that the DLC address in
question is not known to the agent."
SYNTAX OCTET STRING (SIZE (0..64))
AppnNodeCounter ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"An object providing global statistics for the entire APPN
node. A Management Station can detect discontinuities in this
counter by monitoring the appnNodeCounterDisconTime object."
SYNTAX Counter32
AppnPortCounter ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"An object providing statistics for an APPN port. A
Management Station can detect discontinuities in this counter
by monitoring the appnPortCounterDisconTime object."
SYNTAX Counter32

RFC 2155 Definitions of Managed Objects for APPN June 1997
AppnLinkStationCounter ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"An object providing statistics for an APPN link station. A
Management Station can detect discontinuities in this counter
by monitoring the appnLsCounterDisconTime object."
SYNTAX Counter32
AppnTopologyEntryTimeLeft ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Number of days before deletion of this entry from the topology
database. Range is 0-15. A value of 0 indicates that the
entry is either in the process of being deleted, or is being
marked for deletion at the next garbage collection cycle."
SYNTAX INTEGER (0..15)
AppnTgDlcData ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"DLC-specific data related to a connection network transmission
group. For other TGs, a zero-length string is returned.
Examples of the type of data returned by an object with this
syntax include the following:
Token-Ring - MAC/SAP
X.25 Switched - dial digits
X.21 Switched - dial digits
Circuit Switch - dial digits
This MIB does not specify formats for these or any other types
of DLC-specific data. Formats may, however, be specified in
documents related to a particular DLC.
The contents of an object with this syntax correspond to the
contents of the DLC-specific subfields of cv46, documented in
(6)."
SYNTAX OCTET STRING (SIZE (0..64))
AppnTgEffectiveCapacity ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A value representing the effective capacity of a transmission
group. This is an administratively assigned value derived from
Clouston & Moore Standards Track [Page 13]
RFC 2155 Definitions of Managed Objects for APPN June 1997
the link bandwidth and maximum load factor. It is encoded in
the same way as byte 7 of cv47, and represents a floating-point
number in units of 300 bits per second."
SYNTAX OCTET STRING (SIZE (1))
AppnTgSecurity ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A value representing the level of security on a transmission
group. A class of service definition includes an indication of
the acceptable TG security value(s) for that class of service.
The following seven values are defined:
nonsecure(1) -
(X'01'): none of the values listed below;
for example, satellite-connected or
located in a nonsecure country
publicSwitchedNetwork(32) -
(X'20'): public switched network; secure
in the sense that there is no
predetermined route that traffic will take
undergroundCable(64) -
(X'40'): underground cable; located in a
secure country (as determined by the
network administrator)
secureConduit(96) -
(X'60'): secure conduit, not guarded; for
example, pressurized pipe
guardedConduit(128) -
(X'80'): guarded conduit; protected
against physical tapping
encrypted(160) -
(X'A0'): link-level encryption is provided
guardedRadiation(192) -
(X'C0'): guarded conduit containing the
transmission medium; protected against
physical and radiation tapping"
