This variable represents the storage type value for the
traceRcvrFrDna tables.

This attribute specifies the Numbering Plan Indicator (NPI) of the
Dna that is entered. The address may belong to an E.164 or X.121
plan.

The Dna attribute contains digits which form a unique identifier for
the calling end of the trace connection. Dna digits are selected and
assigned by network operators. The maximum Dna length is 15
digits.

This attribute specifies that outgoing calls (from the DTE to the
network) can be made using this particular Dna component.

If this attribute is set to normal, then the default priority for
outgoing calls (from the DTE to the network) using this particular
Dna is normal priority when the priority is not specified in the call.
If this attribute is set to high then the default priority for outgoing
calls using this particular Dna is high priority.

This attribute specifies that outgoing international calls (from the
DTE to the network) can be made using this particular Dna.
This attribute also controls access to another numbering plan, and
specifies that cross-numbering plan calls are allowed.

This attribute specifies the default reliability class of routing for all
calls (from the DTE to the network) using this particular Dna. The
chosen default reliability class of routing normally applies to all
packets (including the call packets) travelling into the network.
A value of high specifies that packets are to be overflowed or
retransmitted at various routing levels. Typically high reliability
results in duplication and disordering of packets in the network,
when errors are detected or during link congestion. The VC handles
the duplication and disordering to ensure that packets are delivered
to the interface in the proper sequence and without duplication.

This attribute specifies that the called end of the connection will not
use the calling end provisioning data for reliability class of routing
to override the provisioning data at the called end.

This attribute specifies that reliability routing signaling is not used.

This attribute is an extension of the Closed User Group (CUG)
facility. If this attribute is set to a value of allowed, it specifies that
outgoing calls (from the DTE to the network) to the open (non-
CUG) part of the network are permitted. It also permits outgoing
calls to interfaces that have Incoming Access capabilities. If set to a
value of disallowed, then such calls cannot be made using this Dna
(the calls will be cleared by the local DCE).
This attribute corresponds to the ITU-T 'Closed User Group with
Outgoing Access' feature.

This attribute specifies that incoming calls (from the network to the
DTE) cannot be made to this Dna.

This variable represents the storage type value for the
traceRcvrFrDnaCug tables.

This attribute specifies the CUG type as either national or
international. A national CUG has significance within the local
network only. An international CUG has significance across
network boundaries.

This attribute specifies the Data Network ID Code of the network
that is administering the international CUG. This attribute is not
used for a national CUG and should be left at its default value.
The dnic value is not an arbitrary number. It is assigned by
international agreement and controlled by ITU-T.

This attribute specifies a numeric identifier of a national or
international closed user group. It is an arbitrary number. This
attribute may also be called CUG in some descriptions. Dnas
defined with this number can only make calls to Dnas defined with
the same interlockCode.

This attribute specifies that this Cug is to be used on all outgoing
calls to the Frame Relay trace receiver.

This attribute specifies that outgoing calls (from the DTE into the
network) can be made using this particular Cug.

This attribute specifies that incoming calls (from the network to the
DTE) cannot be accepted using this Cug.

provisioned value.
If the connection is using dprsOnly data path, the string
dprsOnly is displayed. (dynamic packet routing system)
If the connection is using dprsMcsOnly data path, the string
dprsMcsOnly is displayed.
If the connection is using dprsMcsFirst data path, the string
dprsMcsFirst is displayed.

This attribute displays the call reference number which is a unique
number generated by the switch.The same Call Reference Number
is stored in the interval data (accounting record) at both ends of the
call. It can be used as one of the attributes in matching duplicate
records generated at each end of the call.

This attribute displays the elapsed time representing the period of
this interval data. It is elapsed time in 0.1 second increments since
Vc started.

This attribute displays the number of segments received at the time
command was issued. This is the segment received count
maintained by accounting at each end of the Vc. This counter is
updated only when the packet cannot be successfully delivered out
of the sink Vc and to the sink AP Conditions in which packets may
be discarded by the sink Vc include: missing packets due to subnet
discards, segmentation protocol violations due to subnet discard,
duplicated and out-of-ranged packets and packets that arrive while
Vc is in path recovery state.

This attribute displays the number of segments sent at the time
command was issued. This is the segment sent count maintained by
accounting at the source Vc. Vc only counts packets that Vc thinks
can be delivered successfully into the subnet. In reality, these
packets may be dropped by trunking, for instance. This counter is
not updated when splitting fails, when Vc is in a path recovery state,
when packet forwarding fails to forward this packet and when
subsequent packets have to be discarded as we want to minimize the
chance of out-of-sequence and do not intentionally send out-of-
sequenced packets into the subnet.

This attribute displays the start time of this interval period. If Vc
spans 12 hour time or time of day change startTime reflects new
time as recorded at 12 hour periods or time of day changes.

This attribute displays the number of frames from link discarded
due to lack of resources. It keeps track of the number of frames
from link that have to be discarded. The discard reasons include
insufficient memory for splitting the frame into smaller subnet
packet size.

This attribute displays the number of discarded packets that can not
be forwarded into the subnet because of subnet congestion.
Number of frames from link discarded due to failure in forwarding
a packet from Vc into the subnet.- This attribute is increased when
packet forwarding fails to forward a packet into the subnet. If a
frame is split into multiple subnet packets and a partial packet has
to be discarded, all subsequent partial packets that have not yet been
delivered to the subnet will be discarded as well.

This attribute records the number of frames from link discarded
when the Vc tries to recover from internal path failure.

This attribute displays the number of frames from subnet discarded
due to out of sequence range for arriving too late.

This attribute records the number of subnet packets discarded at the
sink Vc due to the Vc segmentation and combination protocol error.
Usually, this occurs when the subnet discards packets and thus this
statistics can be used to guest the number of subnet packets that are
not delivered to the Vc. It cannot be used as an actual measure
because some subnet packets may have been delivered to Vc but
have to be discarded because these are partial packets to a frame in
which some other partial packets have not been properly delivered
to Vc

This attribute displays the number of subnet packets discarded due
to duplication. Although packets are not retransmitted by the Frame
Relay Vc, it is possible for the subnet to retransmit packets. When
packets are out-of-sequenced and copies of the same packets arrive,
then this attribute is increased.

This attribute displays the number of subnet packets discarded when
data transfer is suspended in Vc recovery.

This attribute displays the number of lost frame timer expiries.
When this count is excessive, the network is very congested and
packets have been discarded in the subnet.

This attribute displays the number times that the out of sequence
byte threshold is exceeded. When the threshold is exceeded, this
condition is treated as if the loss frame timer has expired and all
frames queued at the sink Vc are delivered to the AP. We need to
keep this count to examine if the threshold is engineered properly.
This should be used in conjunction with the peak value of out-of-
sequenced queue and the number of times the loss frame timer has
expired. This count should be relatively small when compared with
loss frame timer expiry count.

This attribute displays the frame relay peak packet count of the out
of sequence queue. This attribute records the maximum queue
length of the out-of-sequenced queue. The counter can be used to
deduce the message buffer requirement on a Vc.

This attribute displays the frame relay peak size of the
sequence packet queue. The subnet may deliver packets out-of-
sequenced. These packets are then queued in an out-of-sequenced
queue, waiting for a packet with the expected sequence number to
come. When that packet arrives, this attribute records the maximum
number of packets that were out-of-sequenced, but now have
become in-sequenced. The statistics is used to measure expected
queue size due to normal subnet packet disorder (not due to subnet
packet discard). Current implementation also uses this statistics to
set a maximum size for the out-of-sequenced queue.

This attribute displays the Vc internal packet's send sequence
number. Note that a 'packet' in this context, may be either a user
data packet, or an OAM frame.

This attribute displays the number of packets which have
retransmission time-outs. When this count is excessive, the network
is very congested and packets have been discarded in the subnet.

This attribute displays the peak size of retransmission queue.
This attribute is used as an indicator of the acknowledgment
behavior across the subnet. Records the largest body of
unacknowledged packets.

This attribute displays the number of successful Vc recovery
attempts.

This attribute displays the number times that the out of sequence
packet threshold is exceeded. When the threshold is exceeded, this
condition is treated as if the loss frame timer has expired and all
frames queued at the sink Vc are delivered to the AP. We need to
keep this count to examine if the threshold is engineered properly.
This should be used in conjunction with the peak value of out-of-
sequenced queue and the number of times the loss frame timer has
expired. This count should be relatively small when compared with
loss frame timer expiry count.

This attribute displays the frame relay peak byte count of the out of
sequence queue. This attribute records the maximum queue length
of the out-of-sequenced queue. The counter can be used to deduce
the message buffer requirement on a Vc.

This variable represents both the value and the index for the
traceSessionFrVcDmepTable.

This entry controls the addition and deletion of
traceRcvrFr components.

This entry controls the addition and deletion of
traceRcvrFrDna components.

This group contains attributes common to all Dnas. This group is
composed of two attributes which define a Dna. These attributes are
used to interpret the format of the address digits.

This group defines the call options for outgoing calls.

This group defines the call options for incoming calls.

The CallOptions group defines additional options for calls which
are not specific to the direction of the call.

This entry controls the addition and deletion of
traceRcvrFrDnaCug components.

Attributes in this group define ClosedUserGroup options associated
with interlockCode. Dnas with the same CUG (interlockCode) can
make calls within this group. Various combinations of attributes are
defined under this option which permit or prevent calls in the same
CUG group.

This entry controls the addition and deletion of
traceRcvrFrDc components.

This group represents operational call data related to Frame Relay
Vc. It can be displayed only for Frame Relay Vc which is created by
application.

*** THIS TABLE CURRENTLY NOT IMPLEMENTED ***
This group defines display of interval data collected by Vc. Data in
this group is variable and may depend on time when this display
command is issued.

*** THIS TABLE CURRENTLY NOT IMPLEMENTED ***
This group defines Frame Relay attributes collected by Frame Relay
Vc.
The purpose of Vc attributes is to aid end users and verification
people to understand the Vc internal behavior. This is particularly
useful when the network has experienced abnormality and we want
to isolate problems and pinpoint trouble spots.
Attributes are collected on a per Vc basis. Until a need is identified,
statistics are not collected at a processor level. Each attribute is
stored in a 32 bit field and is initialized to zero when a Vc enters
into the data transfer state. When a PVC is disconnected and then
connected again, the attributes will be reset. Attributes cannot be
reset through other methods.
Frame Relay Vc uses a best effort data packet delivery protocol and
a different packet segmentation and combination methods from the
General Vc. The Frame Relay Vc uses the same call setup and
control mechanism (e.g. the support of non-flow control data
packets) as in a General Vc. Most General Vc statistics and internal
variables are used in a Frame Relay Vc and are displayed by
software developers
