dsx3FracTable OBJECT-TYPE
SYNTAX SEQUENCE OF Dsx3FracEntry
MAX-ACCESS not-accessible
STATUS deprecated
DESCRIPTION
"This table is deprecated in favour of using
ifStackTable.
Implementation of this table was optional. It was
designed for those systems dividing a DS3/E3 into
channels containing different data streams that
are of local interest.
The DS3/E3 fractional table identifies which
DS3/E3 channels associated with a CSU are being
used to support a logical interface, i.e., an
entry in the interfaces table from the Internet-
standard MIB.
For example, consider a DS3 device with 4 high
speed links carrying router traffic, a feed for
voice, a feed for video, and a synchronous channel
for a non-routed protocol. We might describe the
allocation of channels, in the dsx3FracTable, as
follows:
dsx3FracIfIndex.2. 1 = 3 dsx3FracIfIndex.2.15 = 4
dsx3FracIfIndex.2. 2 = 3 dsx3FracIfIndex.2.16 = 6
dsx3FracIfIndex.2. 3 = 3 dsx3FracIfIndex.2.17 = 6
dsx3FracIfIndex.2. 4 = 3 dsx3FracIfIndex.2.18 = 6
dsx3FracIfIndex.2. 5 = 3 dsx3FracIfIndex.2.19 = 6
dsx3FracIfIndex.2. 6 = 3 dsx3FracIfIndex.2.20 = 6
dsx3FracIfIndex.2. 7 = 4 dsx3FracIfIndex.2.21 = 6
dsx3FracIfIndex.2. 8 = 4 dsx3FracIfIndex.2.22 = 6
dsx3FracIfIndex.2. 9 = 4 dsx3FracIfIndex.2.23 = 6
dsx3FracIfIndex.2.10 = 4 dsx3FracIfIndex.2.24 = 6
dsx3FracIfIndex.2.11 = 4 dsx3FracIfIndex.2.25 = 6
dsx3FracIfIndex.2.12 = 5 dsx3FracIfIndex.2.26 = 6
dsx3FracIfIndex.2.13 = 5 dsx3FracIfIndex.2.27 = 6
dsx3FracIfIndex.2.14 = 5 dsx3FracIfIndex.2.28 = 6
For dsx3M23, dsx3 SYNTRAN, dsx3CbitParity, and
dsx3ClearChannel there are 28 legal channels,
numbered 1 throug h 28.
For e3Framed there are 16 legal channels, numbered
1 through 16. The channels (1..16) correspond
directly to the equivalently numbered time-slots."

4. Appendix A - Use of dsx3IfIndex and dsx3LineIndex This Appendix exists to document the previous use if dsx3IfIndex and dsx3LineIndex and to clarify the relationship of dsx3LineIndex as defined in rfc1407 with the dsx3LineIndex as defined in this document. The following shows the old and new definitions and the relationship: [New Definition]: "This object should be made equal to ifIndex. The next paragraph describes its previous usage. Making the object equal to ifIndex allows proper use of ifStackTable. [Old Definition]: "this object is the identifier of a DS3/E3 Interface on a managed device. If there is an ifEntry that is directly associated with this and only this DS3/E3 interface, it should have the same value as ifIndex. Otherwise, number the dsx3LineIndices with an unique identifier following the rules of choosing a number that is greater than ifNumber and numbering the inside interfaces (e.g., equipment side) with even numbers and outside interfaces (e.g, network side) with odd numbers." When the "Old Definition" was created, my understanding was that it was described this way to allow a manager to treat the value _as if_ it were and ifIndex, i.e. the value would either be: 1) an ifIndex value or 2) a value that was guaranteed to be different from all valid ifIndex values. The new definition is a subset of that definition, i.e. the value is always an ifIndex value. The following is Section 3.1 from rfc1407: Different physical configurations for the support of SNMP with DS3/E3 equipment exist. To accommodate these scenarios, two different indices for DS3/E3 interfaces are introduced in this MIB. These indices are dsx3IfIndex and dsx3LineIndex. External interface scenario: the SNMP Agent represents all managed DS3/E3 lines as external interfaces (for example, an Agent residing on the device supporting DS3/E3 interfaces directly): For this scenario, all interfaces are assigned an integer value equal to ifIndex, and the following applies: ifIndex=dsx3IfIndex=dsx3LineIndex for all interfaces.
The dsx3IfIndex column of the DS3/E3 Configuration table relates each DS3/E3 interface to its corresponding interface (ifIndex) in the Internet-standard MIB (MIB-II STD 17, RFC1213). External&Internal interface scenario: the SNMP Agents resides on an host external from the device supporting DS3/E3 interfaces (e.g., a router). The Agent represents both the host and the DS3/E3 device. The index dsx3LineIndex is used to not only represent the DS3/E3 interfaces external from the host/DS3/E3-device combination, but also the DS3/E3 interfaces connecting the host and the DS3/E3 device. The index dsx3IfIndex is always equal to ifIndex. Example: A shelf full of CSUs connected to a Router. An SNMP Agent residing on the router proxies for itself and the CSU. The router has also an Ethernet interface: +-----+ | | | | | | +---------------------+ |E | | 44.736 MBPS | ds3 M13 Line#A | ds3 C-bit Parity |t | R |---------------+ - - - - - - - - - +------> |h | | | | |e | O | 44.736 MBPS | ds3 M13 Line#B | ds3 C-bit Parity |r | |---------------+ - - - - - - - - - - +------> |n | U | | | |e | | 44.736 MBPS | ds3 M13 Line#C | ds3 C-bit Parity |t | T |---------------+ - - - -- -- - - - - +------> | | | | | |-----| E | 44.736 MBPS | ds3 M13 Line#D | ds3 C-bit Parity | | |---------------+ - - - - -- - - - - +------> | | R | |_____________________| | | | | +-----+
The assignment of the index values could for example be:
ifIndex (= dsx3IfIndex) dsx3LineIndex
1 NA NA (Ethernet)
2 Line#A Router Side 6
2 Line#A Network Side 7
3 Line#B Router Side 8
3 Line#B Network Side 9
4 Line#C Router Side 10
4 Line#C Network Side 11
5 Line#D Router Side 12
5 Line#D Network Side 13
For this example, ifNumber is equal to 5. Note the following
description of dsx3LineIndex: the dsx3LineIndex identifies a DS3/E3
Interface on a managed device. If there is an ifEntry that is
directly associated with this and only this DS3/E3 interface, it
should have the same value as ifIndex. Otherwise, number the
dsx3LineIndices with an unique identifier following the rules of
choosing a number greater than ifNumber and numbering inside
interfaces (e.g., equipment side) with even numbers and outside
interfaces (e.g, network side) with odd numbers.
If the CSU shelf is managed by itself by a local SNMP Agent, the
situation would be:
ifIndex (= dsx3IfIndex) dsx3LineIndex
1 Line#A Network Side 1
2 Line#A RouterSide 2
3 Line#B Network Side 3
4 Line#B RouterSide 4
5 Line#C Network Side 5
6 Line#C Router Side 6
7 Line#D Network Side 7
8 Line#D Router Side 8
5. Appendix B - The delay approach to Unavialable Seconds. This procedure is illustrated below for a DS3 C-Bit parity application. Similar rules would apply for other interfaces covered by this MIB. The procedure guarantees that the statistical counters are correctly updated at all times, although they lag real time by 10 seconds. At the end of each 15 minutes interval the current interval counts are transferred to the most recent interval entry and each interval is shifted up by one position, with the oldest being discarded if necessary in order to make room. The current interval counts then start over from zero. Note, however, that the signal state calculation does not start afresh at each interval boundary; rather, signal state information is retained across interval boundaries. +----------------------------------------------------------------+ | READ COUNTERS & STATUS INFO FROM HARDWARE | | | |BPV EXZ LOS PCV CCV AIS SEF OOF LOF FEBE RAI | +----------------------------------------------------------------+ | | | | | | | | | | | | | | | | | | | | | | V V V V V V V V V V V +----------------------------------------------------------------+ | ACCUM ONE-SEC STATS, CHK ERR THRESHOLDS, & UPDT SIGNAL STATE | | | |<------------- NEAR END ---------------->| |<---- FAR END ----->| | | |LCV LES PCV CCV PES CES PSES CSES SEFS A/U CCV CES CSES SEFS A/U| +----------------------------------------------------------------+ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | V V V V V V V V V | V V V V | +--------------------------------------+ | +-----------------+ | | ONE-SEC DELAY | | | ONE-SEC DELAY | | | (1 OF 10) | | | (1 OF 10) | | +--------------------------------------+ | +-----------------+ | | | | | | | | | | | | | | | | / / / / / / / / / / / / / / / | | | | | | | | | | | | | | | V V V V V V V V V | V V V V | +--------------------------------------+ | +-----------------+ | | ONE-SEC DELAY | | | ONE-SEC DELAY | | | (10 OF 10) | | | (10 OF 10) | | +--------------------------------------+ | +-----------------+ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | V V V V V V V V V V V V V V V

It is an implementation-specific matter whether an agent assumes that the initial state of the interface is available or unavailable.

Security Considerations SNMPv1 by itself is such an insecure environment. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET (read) the objects in this MIB. It is recommended that the implementors consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2274 [12] and the View-based Access Control Model RFC 2275 [15] is recommended. It is then a customer/user responsibility to ensure that the SNMP entity giving access to an instance of this MIB, is properly configured to give access to those objects only to those principals (users) that have legitimate rights to access them. Setting any of the following objects to an inappropriate value can cause loss of traffic. The definition of inappropriate varies for each object. In the case of dsx3LineType, for example, both ends of a ds3/e3 must have the same value in order for traffic to flow. In the case of dsx3SendCode and dsx3LoopbackConfig, for another example, traffic may stop transmitting when particular loopbacks are applied.
dsx3LineType
dsx3LineCoding
dsx3SendCode
dsx3LoopbackConfig
dsx3TransmitClockSource
dsx3LineLength
dsx3Channelization
Setting the following object is mischevious, but not harmful to
traffic
dsx3CircuitIdentifier
Setting the following object can cause an increase in the number of
traps received by the network management station.
