RFC 1304 SIP Objects February 1992
1. The Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
RFC 1155 [3] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management. RFC
1212 [9] defines a more concise description mechanism, which is
wholly consistent with the SMI.
RFC 1156 [4] which defines MIB-I, the core set of managed objects
for the Internet suite of protocols. RFC 1213 [6], defines MIB-
II, an evolution of MIB-I based on implementation experience and
new operational requirements.
RFC 1157 [5] which defines the SNMP, the protocol used for network
access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2. Objects
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
International Standard 8824 [7] defined in the SMI. In particular,
each object has a name, a syntax, and an encoding. The name is an
object identifier, an administratively assigned name, which specifies
an object type. The object type together with an object instance
serves to uniquely identify a specific instantiation of the object.
For human convenience, we often use a textual string, termed the
OBJECT DESCRIPTOR, to also refer to the object type.
The syntax of an object type defines the abstract data structure
corresponding to that object type. The ASN.1 language is used for
this purpose. However, the SMI RFC 1155 [3] purposely restricts the
ASN.1 constructs which may be used. These restrictions are
explicitly made for simplicity.
The encoding of an object type is simply how that object type is
represented using the object type's syntax. Implicitly tied to the
notion of an object type's syntax and encoding is how the object type
is represented when being transmitted on the network. The SMI
specifies the use of the basic encoding rules of ASN.1 International
Standard 8825 [8], subject to the additional requirements imposed by
the SNMP.
SNMP Working Group [Page 2]
RFC 1304 SIP Objects February 1992
2.1. Format of Definitions
Section 4 contains contains the specification of all object types
contained in this MIB module. The object types are defined using the
conventions defined in the SMI, as amended by the extensions
specified in RFC 1212 [9].
3. Overview
These objects are used when the particular media being used to
realize an interface is a SIP interface. At present, this applies to
these values of the ifType variable in the Internet-standard MIB:
sip (31)
For these interfaces, the value of the ifSpecific variable in the
MIB-II [6] has the OBJECT IDENTIFIER value:
sip OBJECT IDENTIFIER ::= { transmission 31 }
The definitions contained herein are based on the SIP specifications
in Bellcore TR-TSV-000772 and TR-TSV-000773 [11,12].
The SIP (SMDS Interface Protocol) protocol stack is defined as
follows in TR-TSV-000772 [11]:
___________________
| |
| SIP Level 3 [11] |
|___________________|
| |
| SIP Level 2 [11] |
|___________________|
| |
| PLCP [12] |
|___________________|
| |
| DS1 or DS3 [12] |
|___________________|
The PLCP (Physical Layer Convergence Procedure) adapts the
capabilities of the transmission system (DS1 or DS3 formats) to the
service expected by SIP Level 2. Managed objects for DS1 and DS3
Interface Types are defined in RFC 1232 [13] and RFC 1233 [14]
respectively (and amended in RFC 1239 [17]), and can be utilized for
management of SIP interfaces. This document defines managed objects
for the remaining protocol levels of the SIP Interface Type. This
document does not specify objects for the management of subscription
SNMP Working Group [Page 3]
RFC 1304 SIP Objects February 1992
or configuration of Subscriber-Network Interfaces (SNIs). Those
objects are defined in Definitions of Managed Objects for SMDS
Subscription [18]. Bellcore requirements on these objects are
specified in TA-TSV-001062 [16].

contained in the address subfield can be used to
represent addresses up to 15 decimal digits. Each
decimal digit shall be encoded into four bits
using Binary Coded Decimal (BCD), with the most
significant digit occurring left-most. If not all
15 digits are required, then the remainder of this
SNMP Working Group [Page 18]
RFC 1304 SIP Objects February 1992
field shall be padded on the right with bits set
to one. An error is considered to have occurred:
a). if the first four bits of the address
subfield are not BCD, OR b). if the first four
bits of the address subfield are populated with
the country code value 0001, AND the 40 bits which
follow are not Binary Coded Decimal (BCD) encoded
values of the 10 digit addresses, OR the remaining
16 least significant bits are not populated with
1's, OR c). if the address subfield is not
correct according to another numbering plan which
is dependent upon the carrier assigning the
numbers and offering SMDS.
- Source Address Field Format Error,
The description of this parameter is the same as
the description of the Destination Address Field
Format Error.
- Invalid BAsize Field Value,
An error is considered to have occurred when the
BAsize field of an SIP L3PDU contains a value less
that 32, greater than 9220 octets without the
CRC32 field present, greater than 9224 octets with
the CRC32 field present, or not equal to a
multiple of 4 octets,
- Invalid Header Extension Length Field Value,
An error is considered to have occurred when the
Header Extension Length field value is not equal
3.
- Invalid Header Extension - Element Length,
An error is considered to have occurred when the
Header Extension - Element Length is greater than
12.
- Invalid Header Extension - Version Element
Position, Length, or Value,
An error is considered to have occurred when a
Version element with Length=3, Type=0, and Value=1
does not appear first within the Header Extension,
or an element Type=0 appears somewhere other than
SNMP Working Group [Page 19]
RFC 1304 SIP Objects February 1992
within the first three octets in the Header
Extension.
- Invalid Header Extension - Carrier Selection
Element Position, Length, Value or Format,
An error is considered to have occurred when a
Carrier Selection element does not appear second
within the Header Extension, if the Element Type
does not equal 1, the Element Length does not
equal 4, 6, or 8, the Element Value field is not
four BCD encoded decimal digits used in specifying
the Carrier Identification Code (CIC), or the
identified CIC code is invalid.
- Header Extension PAD Error
An error is considered to have occurred when the
Header Extension PAD is 9 octets in length, or if
the Header Extension PAD is greater than zero
octets in length and the Header Extension PAD does
not follow all Header Extension elements or does
not begin with at least one octet of all zeros.
- BEtag Mismatch Error,
An error is considered to have occurred when the
Beginning-End Tags in the SIP L3PDU header and
trailer are not equal.
- BAsize Field not equal to Length Field Error,
An error is considered to have occurred when the
value of the BAsize Field does not equal the value
of the Length Field.
- Incorrect Length Error, and
An error is considered to have occurred when the
the Length field value is not equal to the portion
of the SIP L3PDU which extends from the
Destination Address field up to and including the
CRC32 field (if present) or up to and including
the PAD field (if the CRC32 field is not present).
As an optional check, an error is considered to
have occurred when the length of a partially
received SIP L3PDU exceeds the BAsize value.
SNMP Working Group [Page 20]
RFC 1304 SIP Objects February 1992
- MRI Timeout Error.
An error is considered to have occurred when the
elapsed time between receipt of BOM and
corresponding EOM exceeds the value of the MRI
(Message Receive Interval) for a particular
transport signal format.
An entry is indexed by interface number and error
type, and contains Source Address, Destination
Address and a timestamp. All these errors are
counted in the sipL3Errors counter. When
sipL3PDUErrorTimeStamp is equal to zero, the
SipL3PDUErrorEntry does not contain any valid
information."
